  • AAC (Autoclaved Aerated Concrete)
  • Fibre Cement Sheeting (Fibro/Blue board)
  • Rendered expanded polystyrene
  • Clay and Concrete Brickwork
  • Tilt panel walls
  • Other primed exterior surfaces

SUBSTRATE PREPARATION

  • Areas not to be coated should be masked and protected
  • All surfaces to be coated must be clean, sound, free from contaminants including; oil, mould release, dust, dirt, silicone, mud, grease, salt, efflorescence, animal droppings and any loose or flaking material.
  • All substrates must be primed, normally with Acryloc Prime Seal.
  • Apply the Prime Seal at the rate of 12.5-16.5m2/L and allow to dry (approx 30mins).
  • (Note: The concentrate form of Prime Seal must be diluted before use).

APPLICATION

  • Acryloc Patch does not require thinning but mixing with a power stirrer will enhance workability and coverage.
  • For setting of Joints or installation of Beads and Trims, add Portland Cement to the pail as per the following table:
Pail Size Cement Addition
5 Litre 350g to 700g
10 Litre 700g to 1.4kg
15 Litre 1kg to 2kg

Caution: Excess quantity of cement can cause the product to have a reduced pot life and hamper application, workability and durability. Do not thin after addition of cement.

  • Mix thoroughly with a broad, flat stirrer, using an upward lifting action, or power mixer.

Setting Joints (use Acryloc Patch with added Cement)

  • Apply a 2mm layer of Acryloc Patch into the recessed joint.
  • Apply a single strip of alkali resistant fiberglass tape and trowel into the freshly applied material.
  • When the tape is fully bedded, skim over with one (1) further coat of Acryloc Patch, feathering edges as neatly as possible.

Beads & Trims (use Acryloc Patch with added Cement)

Either,

  • Use Acryloc Patch to fix the trim by fully coating the inside of the trim with Acryloc Patch, pressing firmly into place and trowelling off the outside of the trim to ensure that all holes are filled; Or, if the trim is already fixed in place,
  • Apply Acryloc Patch to the trim, trowelling it into the holes to ensure that there are no voids.

Skim Coating

  • Apply Acryloc Patch to the surface to a thickness of approx 1.5mm.
  • Where the entire surface is being skim coated, commence at the top of the wall panel. Two (2) or more applicators may be required for large uninterrupted wall areas.
  • Allow surface to stand for a short time prior to finishing.
  • Rub up or ‘finish’ with a suitable float either in a vertical or circular fashion, terminating only when a whole area or section is completely coated.
  • Typically one (1) coat should be adequate if the substrate is flatt and level, but a second coat may be applied if required.

Important Notes

  • Care should be taken to keep Acryloc Patch off windows and adjacent surfaces that are not to be coated, as it can be very difficult to remove once allowed to dry.
  • Acryloc Patch must be over coated using the appropriate components selected from the Wallcote system.
  • Do not apply Acryloc Patch when rain is anticipated within 5 hours of completion of the days work, longer in damp, cold +/or humid conditions.
  • Avoid application in full sun, on hot surfaces or in hot windy conditions.
  • Application should be carried out on a day with temperatures above 10°C and below 32°C.
  • Coated area must be protected from damage until the completion of the project; finished work must be protected from rain, frost and severe weather conditions until fully dried.

  • A wet edge should be maintained throughout the application and day joints formed at corners, expansion joints or mouldings where they will not be evident after completion.

METHOD

  • Apply Acryloc Roll on Texture to the surface with a suitable texture roller. Load the roller generously and apply in strips 500mm-750mm in length.
  • Once five (5) or six (6) strips have been applied, roll across to even out the surface.
  • Finish in one direction for an even texture.
  • Repeat the above steps, only re-rolling 70-100mm into the previously coated area.
  • Work quickly and without interruption, laying off from the edge to avoid texture imperfections.
  • If a small area is missed, it is best to touch up when the area is dry. Running out of material midway through a wall surface should be avoided at all times. In this event, feather the edge and allow texture to dry, then marry in with new material.
  • Acryloc Roll on Texture should not be extended (spread) too far; otherwise durability and hiding power may suffer.

Important Notes

  • Care should be taken to keep Acryloc Roll on Texture off windows and adjacent surfaces that are not to be coated, as it can be very difficult to remove once allowed to dry.
  • Do not apply Acryloc Roll on Texture when rain is anticipated within 5 hours of completion of the days work, longer in damp, cold +/or humid conditions.

  • Apply one coat of Acryloc Exterior Primer and allow to dry (approx 45mins)

APPLICATION

  • Armourflex Exterior Acrylic may require thinning, depending upon the application method used. Up to 1L of clean water may be added to a 15L pail (~6.5%) without the need to apply any extra coats. Thorough mixing is essential. Greater than 7% addition is not recommended.

Method

  • Mix thoroughly with a broad, flat stirrer, using an upward lifting action, or power mixer and check that the colour is correct before commencing work.
  • Care should be taken to keep Armourflex Exterior Acrylic off windows and adjacent surfaces that are not to be coated, as it can be very difficult to remove once allowed to dry.
  • Acryloc Exterior Acrylic can be applied using a roller, brush, pad, HVLP spray equipment or airless spray equipment.
  • If using a roller, roll the coating in one (1) direction only, to avoid cross masking of layers
  • If using airless spray equipment, a 19-21 thou tip and white gun filter is recommended. Try to maintain a Wet Film Thickness of 100-125µm for each single coat by checking regularly with a Wet Film Thickness Gauge.

Ecobrick

Efficient and environmentally friendly, ecobrick is lightweight (approximately half the weight of a clay fastwall brick). When used as an internal wall in conjunction with the traditional clay brick external wall, ecobrick improves the resistance to heat moving through that wall by 57%.

Ecobrick not only improves the thermal efficiency of walls, but improves their acoustic values as well. The aerated part of ecobrick is made up of non-connected air bubbles that do not allow
noise to travel across these spaces. As a result, noise bounces off a hard surface, which means that when you use ecobrick inside a room, the background noise will disappear. These
air bubbles are also the reason for ecobrick’s higher resistance to heat, in the same way as bulk insulation works in a roof space.

Ecobrick:

  • 6 star energy rating
  • lightweight and simple to install
  • excellent acoustic and fire properties
  • environmentally friendly and recyclable

Introduction

BGC Water Resistant (WR) plasterboard complies with the requirements of AS2588Gypsum Plasterboard’, (refer CSIRO Test Report DTS 713).

BGC Plasterboard designed and developed WR Plasterboard for wet area walls, in residential and commercial buildings, such as bathrooms, laundries, toilets and cleaning room areas.

BGC WR plasterboard is to be installed in accordance with AS 2589.1; 2007Gypsum Plaster Linings in Residential and Light Commercial Construction – Application and Finishes” and as detailed in AS 3740:2004Waterproofing of Wet Areas within Residential Buildings”.

BGC WR Plasterboard has a light-blue fungal resistant multi-layered facing board for easy identification. It is available in 10mm and 13mm thicknesses with recessed edges, ready for taping and jointing with proprietary water resistant stopping and setting compounds.

BGC WR Plasterboard has a low absorption core, eliminates the probability of water wicking, therefore preventing possible damage to the supporting structure and wall finishes.

Key Benefits

  • Cost effective, drywall wet-area lining system.
  • High serviceability performance board.
  • Dimensionally stable substrate for tiled wall finishes.
  • Ready for decorative paint and thin cover finishes.

Plasterboard Finish Selection

The selection of plasterboard finish in wet areas depends on the desired tiled surfaces and other wall decorations required. Generally, use Class 3 and 4 finishes in wet areas, as detailed in AS 2589.1-2007.

Where tiles are used, the finish can be of a lower standard and where other decoration is required, the standard is higher. BGC Plasterboard recommends the architect’s specifications for the level of finish required.

Handling & Storage

Water Resistant Plasterboard should be stacked flat, up off the ground and supported on level, equally spaced (max 450mm) gluts.

Care should be taken to ensure edges of the Water Resistant Plasterboard are not damaged when handling.

Water Resistant Plasterboard should be delivered to site immediately prior to installation to reduce the risk of damage.

Installation

Install and fix BGC WR plasterboard sheets horizontally to minimise the number of joints and to minimise light reflections across the joints.

Cut the BGC WR Plasterboard from the face and snap back away from the score, then cut the back paper face toward the front face.

Use a straightedge for neat straight cuts.

Framing

Install and fix BGC WR plasterboard to timber or Cold Formed Steel (CFS) framing or furring channels, which satisfy the BCA requirements and which have been plumbed true and straight.

NOTE: Timber shall be kiln dried with a moisture content below 16%.

Prior to installing and fixing BGC WR Plasterboard, ensure that the preceding trades have certified, that –

  • Structural movement will not occur (or is minimised) at wall-to-wall and floor-to-wall junctions.
  • All noggings, trims and the like, are correctly installed and fixed for the bath, basins and other fixtures (Noggings are spaced at 600mm maximum centres for 10mm plasterboard and 800mm maximum centres for 13mm plasterboard).
  • All perimeters, corner and control joint flashings are in place and correctly installed.

Fixing

Fix BGC WR Plasterboard sheets horizontally to wall framing and or metal framing, with the bottom sheets first, at 6-10mm clear of the finished floor.

Set out sheets around all wall openings, with cutouts 200mm horizontally and 250mm vertically, to prevent corner cracking.

For untiled walls space fasteners at 600mm maximum centres on internal studs and at 150mm for internal and external corners. See Figure 1.

Press sheets firmly against the frame and fasten along one recessed edge at each framing member.

For all wet areas fasten sheets with corrosion resistant Class 3, or better screws, which comply with AS 3566:

For timber-framing plasterboard nails must comply with AS 2334; 1980 Steel Nails – Metric series and have a minimum Class 3 or better corrosion resistance.

BGC Plasterboard recommends the use of screw fasteners instead of nails.

NOTE: When fixing into preservative treated timbers, Class 3 AS 3566.2-2002 coatings of screws and nails are to be used.

NOTE: Do not fix BGC WR Plasterboard with adhesives.

Figure 1 – Sheet Set Out Untiled Areas

Tiled Walls

Position fasteners between 10mm and 16mm from the edge of the sheets at the correct spacing to carry the loads of the tiles.

For walls with tiles 6.5mm thick or 12.5 kg/m2 or less, space fasteners at 200mm maximum centres on the intermediate studs and at 150mm on internal and external corners, butt joints and around openings.

Where tiles are greater than 6.5mm thick or 32 kg/m2, space all fasteners at 100mm maximum centres in the centre of sheets, on internal and external corners, butt joints and around openings.

Tile adhesive should be compatible with the waterproofing membrane.

Pre-Formed Shower Base and External Shower Tray

Preliminary work and detail fixing out is similar for external shower trays and preformed shower bases, as shown in Figure 2.

Install and fix perimeter-flashing angles, at the wall/ floor junction and preformed shower bases or external shower trays, prior to fixing WR plasterboard lining.

Cut and install PVC corner angle, down inside the pre-formed shower base; Figure 8 and fasten to framing at 600m centres, in a staggered pattern.

Seal the lower edge of WR plasterboard sheets, whether cut or not, with a proprietary wet-area acrylic sealant to prevent potential moisture wicking.

Figure 2
Pre-Formed Shower Base and External Shower Tray – cont.
Install and fix sheets to the wall framing 6mm clear of the shower tray up-stand; See Figure 2 and of the mortar bed in the external shower tray.

Caulk the bottom edge of the sheets and the shower base or the mortar bed and around plumbing fixtures with a flexible sealant. See Figures 2 & 3.

Penetrations 

The WR Plasterboard must be cut out to leave a 6 mm gap all round the fixture. This gap must be filled with a mould resistant flexible sealant.

BGC recommends using a hole saw to make a neat cut out for fittings such as taps, shower roses etc. Do not use a hammer.

Additional framing must be installed as required to properly support all fixtures.
Figure 3 – Sealing Penetrations
Insitu Shower Tray
Install and fix perimeter-flashing angles, at the wall/floor junction.

Cut and install PVC corner angle and fasten to framing at 600m centres, in a staggered pattern.
Seal the lower edge of water resistant plasterboard sheets, whether cut or not, with a proprietary wet-area acrylic sealant to prevent potential moisture wicking.

Install and fix sheets to the wall framing, as outlined previously, 6mm clear off the floor.
Form a bond-breaker with closed-cell foam backing rod and masking tape at the bottom edge of the Plasterboard at wall/floor junction, as shown in Figure 4.

Caulk around plumbing penetrations and up the internal corners of the shower with flexible sealant.

Apply a proprietary liquid membrane material to the face of the plasterboard and floor to form an insitu internal shower tray.

Follow the membrane manufacturers’ instructions.

Apply the membrane to the vertical corner to a minimum height of 1800mm from the finished floor surface.

The liquid membrane is to extend 75mm minimum each side of the corner.

Note: Use only insitu membrane materials appraised and approved by recognised authorities.

Figure 4
Shower Over Bath

Preliminary work and fixing out detail is similar for preformed shower bases and in part the insitu tray details, see Figure 13.

Cut and install PVC corner angle, down inside the bath up-stand flange and fasten to framing at 600mm centres, in a staggerd pattern, see Figure 5.

Seal the lower edge of water resistant plasterboard sheets, whether cut or not, with a proprietary wet-area acrylic sealant, to prevent potential moisture wicking.

Install and fix sheets to the wall framing, as outlined previously 6mm clear off the bath up-stand.
Caulk the bottom edge of the sheets and the bath edge around plumbing fixtures with a mould resistant flexible sealant.

Apply a proprietary branded liquid membrane 150mm above the bath edge and wall surround, to a minimum height of 1800mm above the finished floor level and 75mm each side of the corner, see Figure 5 & 13.

Perimeter and Bath Flashing

Vertical corner is to angle finish inside perimeter wall angles and also pre-fabricated shower tray/base, insitu-laid trays or the like Refer Figure 5.

Figure 5

Structural Movements and Control Joints

Buildings and their component parts move over time due to various factors which may lead to building and or system failures if design, materials and installation are not satisfactory.

To minimise the risk of system failure take care when designing, detailing, installing and finishing all aspects of wet areas.

The design of wet areas must take into account any relative movements in the building structure and components, due to loading and temperature and humidity variations and the like. See Figure 6.

Figure 6

In long runs of wall, control joints should be set at 5.4 metres maximum in non-tiled areas, and at 4.2 metres maximum, in tiled areas or at construction joints, which ever is the lesser. Control joints must allow for the differential expansion and contraction between the structure, wall lining and tiles. Control joints, must be constructed with double studs, with a gap to suit the control joint type. Refer Figure 7.

Figure 7

Corner Jointing

Corners are set and finished with paper tapes in wet areas for internal corners, or casing beads for external corners.

However, in wet area construction, corners above pre-formed shower bases, insitu trays and shower over baths situations require special attention to detail, as noted.

Vertical Corner Flashing

In tiled walls, vertical corner flashings finish inside pre-fabricated shower tray/base, insitu-laid trays or the like. Refer Figure 8.

 Figure 8

Jointing

Wet area plasterboard joints must satisfy the BCA requirements and comply with AS 2589.1:2007

All WR plasterboard joints in wet areas must be set with perforated paper tapes and proprietary branded base and flushing compounds such as BGC WR Taping Cement.

The wet area base-coat system is typically a two-coat system under tiled areas and a three-coat system where tiles are not used.

All horizontal, vertical and corner joints and fastener points must, be stopped and set with the same materials, to ensure water resistance across the wall areas.

The use of correct materials, application and sequencing of taping and jointing is important and any deviation may result in joint failure.

Mixing of different proprietary compounds or application of setting type compounds over acrylic drying compounds, may lead to joint failure and will negate any proprietary item warranties.
Only use drying type topping or finishing compounds over water-resistant acrylic drying type base-coat compounds.

NOTE: Do not use setting type compounds over water-resistant acrylic drying type compounds.

Do not use self adhesive tapes.

BGC Plasterboard wishes to acknowledge and recommend treatment and installation of wet areas as per the Australian Standards

 External Alfresco Ceilings

The construction of external entertainment areas attached to Fasteners a dwelling with a lined ceiling in Australia is proving popular. These areas are inherently exposed to much more arduous conditions to that of the rest of the house internally.

Areas that could be included are areas outside the main enclosed living area of a house or similar environment. E.g. carports, garage ceilings, alfresco areas or similar.

Environment

The environments of external ceilings are often severe and can be effected by;-

  • The generally constant high humidity
  • The climate of the region
  • Wind loads
  • Garage Roller Door Vibration
  • Insufficient perimeter support

To overcome potential problems in these areas it is important to consider the following points;-

  • The correct choice and installation of lining materials, fasteners, jointing and coating materials, designed to suit the environments
  • Correct placement and installation of battens and installation methods
  • The design and detail of the structural components and their protection from moisture
  • Final paint decoration

Condensation

  • Surface condensation and wind loads can be the main causes of lining board and jointing system failure. Insufficient protection can lead to the plasterboard distorting as well as potential mould attack.
  • Use sarking or foil backed insulation underneath metal roofing as this is more susceptible to condensation build up than roofing tiles.
  • It is important that ceiling cavity areas are well ventilated to prevent condensation build up, the Installation of eave and gable vents, roof ventilators etc can assist in this.
  • Building materials and systems may be adversely affected by these severe environmental and physical conditions, which if not installed correctly can lead to ceiling failure and or collapse.

Recommended BGC Plasterboard Materials

  • 10mm Water Resistant Plasterboard
  • 13mm Water Resistant Plasterboard
  • 13mm Wet Area Fireboard
  • 16mm Wet Area Fireboard
  • 10mm Moisture Resistant Flameboard

Fasteners

Fasteners used can be screws or nails and must be to Class 3. When fixing BGC Plasterboard to an external ceiling, use fasteners in the 1/3 spacing method using appropriate fasteners & stud adhesive.

Recommended fixing & spacing

Screw fixings:
Plasterboard width # of Screws Position of screws.
1200mm 5 evenly spaced 1 per recess & equally spaced 300mm centres.
1350mm 7 evenly spaced 1 per recess & equally spaced 225mm centres.

Nail fixings:

Plasterboard width # of nails Position of nails.
1200mm 7 evenly spaced 1 per recess & equally spaced 200mm centres.
1350mm 9 evenly spaced 1 per recess & equally spaced 170mm centres.
Installation

All perimeters to have appropriate framing/noggings etc in order to support all sheet edges. Perimeters to be screw fixed only at 300mm centres. The perimeter may be fixed out with timber noggings or metal plasterers angle (Rondo P18) or equivalent. Framing centres to be at a maximum of 450mm.

All flush joints must be back blocked in accordance with AS/NZS2589:2007.

Paper tape must be used in conjunction with setting type base products in the recessed joins. Base and topping to comply with ASTM C475.

Plasterboard sheets to have a minimum 6mm space from perimeter walls. Fascia boards/perimeter beams should continue at least 20mm below the bottom of the plasterboard ceiling or the perimeter wall/ceiling trim.

Painting

Roll or brush on high quality sealer undercoat designed for external application. Use only manufacturer’s recommended external paint for this application.

Level 4 shall be the minimum level finish for plasterboard.
Level 5 is recommended when critical lighting conditions apply.

Considerations

Before lining the building it is prudent to consider the following design and construction issues;-

  • Consideration must be given to the framing, this may vary throughout Australia especially in high wind and coastal areas
  • It is highly recommended to batten out the ceiling with Rondo 16mm metal battens or 16mm Furring Channel or 28mm Furring Channel or equivalent. These are to be fixed on the appropriate direct fix clips.
  • High-pressure differentials across a wall, may cause the wall to bend and move; hence
  • Ensure that wall and ceiling areas do not exceed maximum allowable areas, heights or lengths, and provide movement and or relief control joints where necessary.

Plasterboard and Cornice

BGC Plasterboard is an interior lining material which provides a blemish free, monolithic surface ready for decorative paint and thin cover finishes for both commercial and residential applications.

BGC Plasterboard is manufactured using a gypsum core covered with a linerboard which is wrapped around the gypsum to protect the core.

Complementing its plasterboard sheet range, BGC Plasterboard manufactures a range of cove and decorative cornices which provide a solution for the finishing of joints between walls and ceilings.

BGC Plasterboard:

  • Interior wall lining system
  • Suitable for residential & commercial applications
  • Cost effective
  • Ready for decoration
  • Quick and simple to install
  • Excellent acoustic performance
Product Information

BGC Plasterboard is purpose designed as a complete plasterboard wall and lining system, which complies with the requirements of the Building Code of Australia (BCA).

BGC Plasterboard has been tested by the CSIRO (Manufacturing & Infrastructure Technology) in accordance with AS 2588 – 1998: Gypsum Plasterboard; see report DTS698, April 2003.

BGC Plasterboard interior lining provides a blemish free, monolithic, smooth surface ready for decorative paint and thin cover finishes for homes, offices and institutional buildings.

BGC Plasterboard is to be installed as detailed in AS 2589:2007 ‘Gypsum Linings – Application and Finishes’.

Support framing must conform to the BCA and Australian Standards, be plumb, true and level, prior to the application of the plasterboard, see table 2 page 7. Refer to section 4.2.2 AS2589:2007

BGC Plasterboard may be fixed to timber or CFS (Cold-Formed Steel) light-steel framing or masonry, using plasterboard screws, nails and or adhesive.

Only screws or nails must be used for tiled areas and over existing lining or vapour barriers.

Jointing is effected with Plaster Cement Jointing Compounds and paper tape, to give reinforced crack resistant and seamless surfaces.

Key Benefits

  • Cost effective, easy to install drywall system.
  • Seamless, smooth monolithic appearance.
  • Excellent fire resistance and acoustic performance.
  • High serviceability performance.

Plasterboard Finish Selection

Selecting the level of finish of the interior lining depends on the function of the space, lighting and the desired decorative surfaces required.

For most applications, Finish Levels 4 or 5 are used, as detailed in AS 2589:2007.

Level 3 is used, where heavy to medium texture finishes are applied and the lighting is non-critical.

Level 4 is most commonly used in commercial and residential work, where the finishes are satin, flat or low sheen paint systems and the lighting is non-critical.

For large area walls and ceilings, where critical and severe glancing lighting have an effect, a Level 5 finish must be used to minimize any adverse effects of harsh lighting.

Early Fire Hazard Indices

BGC Plasterboard has been tested by the NATA accredited AWTA for fire resistance in accordance with AS 1530.3; see Report Test Number: 7-518246-CN, April 2003.

Installation

BGC Plasterboard recommends that this section should be read in conjunction with the architects’ specifications to determine the Level of Finishes.

BGC Plasterboard should be installed after all preceding trades have been completed.

Ceilings should be installed first. BGC Ceilingboard should preferably be fixed with their long edges perpendicular to the windows or light sources, to obviate unwanted light reflections across the joints.

For the walls, BGC Plasterboard sheets should be laid with their long edges horizontal, to minimise the number of joints as well as light reflections across the joints. This is most important when Finish Levels 4 or 5 are specified, as indicated in Table 2 page 7.

BGC Plasterboard may be cut by scoring the face side and snapping back away from the score. Then cut the paper on the second side following the original score line. Neat straight cuts can be made using a straight edge.

The cut edges should be sanded smooth to form clean joints.

Control joints should be set at twelve (12) metres maximum, or at construction joints, which ever is the lesser (refer page 6).

Control Joints

Control joints must be installed in walls and ceilings at a maximum spacing of 12m, or at control/construction joints, whichever is the lesser.

Architectural features, openings, and the like may be used as control joint set out points.

Rondo ‘P35’ or MBS ‘PXJ-30’ are suitable control/ expansion joints.

Control joints are centrally located across the 15mm minimum gap between adjacent BGC Plasterboard sheets, and the flanges nailed at 300mm centres to the framing behind.

Framing

BGC Plasterboard may be fixed to timber, CFS light steel framing or furring channels, which satisfy the BCA requirements and which have been plumbed true and straight.

Timber framing must comply with the requirement of AS1684 ‘National Timber Framing Code’ and AS1720.1&.2 ‘Timber Structures’ and have a moisture content less than 16% at time of lining.

CFS light-steel framing must be in accordance with AS/NZS4600 ‘Cold-Formed Steel Structure Code’, AS3623 ‘Domestic Metal Framing’ and AS1397.

BGC Plasterboard may be fixed to CFS steel framing not exceeding 1.25mm BMT. Framing members must have a 35mm minimum face width for nail fixing and 32mm for screw fixing.

Steel Frame Application

Framing

Frames must be plumbed true and straight, to comply with the degree of finish required of the BGC Plasterboard.

The tolerance deviation over 1.8m spans, along and across members, for 90% of the wall and ceiling framing, shall be as set out in Table 2.

*Refer to the Curveboard brochure for further information on spacing of framing members as this may change depending on the angle of the curve required.

Adhesive, Nails or Screws

BGC Plasterboard may be fixed to the framing with either adhesive and nails or adhesive and screws as appropriate.

Water-based acrylic gypsum plaster adhesives such as BGC Stud Adhesive, which comply with AS2753, are suitable for fixing BGC Plasterboard to both metal and timber framing

Adhesive fixing is used in conjunction with fasteners, except for wet and tiled areas, fire-rated construction, over vapour-barriers or existing work, where mechanical fasteners, nails or screws only must be used.

The position of daubs of BGC Stud Adhesive ‘O’ and permanent fasteners ‘X’ should be as set out as shown in the Table 4.

Fixing to Framing

Walls

Daubs of BGC Stud Adhesive, 25mm diameter x 15mm high are positioned in the pattern as shown in Table 4, spaced at a maximum of 300mm and a minimum of 200mm.

BGC Stud Adhesive must not be used at wall-to-wall and wall-to-ceiling junctions, around openings, butt joints or fastener points.

BGC Plasterboard is placed horizontally along each wall. Sheets to be packed 6-10mm from floor and fastened along the top recessed edge at each stud or furring channel.

The sheets are then pressed firmly against the studs and temporary fastened midway across the sheet at every second stud or furring channel.

Next, fasten the other recessed edge at each stud, or furring channel.

Fasteners must not coincide with BGC Stud Adhesive daubs, and fasteners should be kept to a minimum distance of 200mm from adhesive daubs.

Fasteners around openings should be placed at a maximum spacing of 300mm centres. Allow at least 24 hours for the adhesive to set.

Interior Ceilings

BGC Stud Adhesive, 25mm dia. x 15mm high, are positioned in the pattern as shown in Table 4, spaced at maximum of 250mm and minimum of 200mm centres.

BGC Stud Adhesive must not be used at wall-to-wall and wall-to-ceiling junctions, around openings, butt joints or fastener points.

BGC Ceilingboards are placed at right angles to the ceiling joists, battens or furring channels, and fastened along one recessed edge at each joist, batten or furring channel.

Next, press the sheets firmly against the framing, and fix two nails (for timber framing) or one screw (for CFS steel framing), along the centre of the sheet at each framing member.

Then, fasten off the sheets along the other recessed edge, at each framing member. Fasteners must not coincide with BGC Stud Adhesive daubs, and fasteners should be kept to a minimum distance of 200mm from BGC Stud Adhesive daubs.

Where allowed, fasteners at butt joints and around openings should be placed at a maximum spacing of 150mm for nails and 200mm for screws.

Allow at least 24 hours or 48 hours in slow drying weather, for the BGC Stud Adhesive to cure.

Ceiling Sheet Application

Exterior Ceilings

An exterior ceiling covers areas outside the main enclosed living area of a house such as entertainment areas (Alfresco), carports and garages.

The different environments of exterior ceilings are often severe and can be effected by:

  • The generally constant high humidity,
  • The climate of the region,
  • Wind loads,
  • Garage Roller Door Vibration,
  • Insufficient perimeter support.

To overcome potential problems in these areas it is important to consider the following points:

  • The correct choice and installation of lining materials, fasteners, jointing and coating materials, designed to suit the environments,
  • Correct placement and installation of battens and installation methods,
  • The design and detail of the structural components and their protection from moisture,
  • Final paint decoration.
Condensation
Surface condensation and wind loads can be the main causes of lining board and jointing system failure. Insufficient protection can lead to the plasterboard distorting as well as potential mould attack.
Use sarking or foil backed insulation underneath metal roofing as metal is more susceptible to condensation build up than roofing tiles.
It is important that ceiling cavity areas are well ventilated to prevent condensation build up. The installation of eave and gable vents, roof ventilatiors etc. can assist in this by providing permanent cross flow ventilation.

Building materials and systems may be adversely affected by these severe environmental and physical conditions, which if not installed correctly can lead to ceiling failure and or collapse.

Plasterboard Materials

BGC 10mm and 13mm Water Resistant Plasterboard, 10mm Moisture Resistant Flameboard, 10mm Ceilingboard and 13mm Plasterboard may be used as suitable lining materials in exterior ceiling areas.

All perimeters must have appropriate framing/noggings etc. In order to support all sheet edges. Perimeters to be screw fixed only at 300mm centres. The perimeter may be fixed out with timber noggings, metal plasterers angle (Rondo P18) or equivalent.

Plasterboard sheets fixed to exterior ceilings must be either mechanically fixed with appropriate screws or using the 1/3 spacing method using appropriate screws and stud adhesive as per AS/NZS 2589:2007. Paper tape must be used in conjunction with setting type base products in the recessed joins. Base and topping to comply with ASTM C475. All trowelled joins to be back blocked in accordance with AS/NZS 2589:2007.

Plasterboard sheets to have a minimum 6-10mm space from perimeter walls.

Fascia boards/perimeter beams should continue at least 20mm below the bottom of the plasterboard ceiling or the perimeter wall/ceiling trim.

Framing centres to be at a maximum of 450mm.

Ceiling Area

For long runs of sheets and or large sheet areas, with set joints, movement control (expansion) joints must occur at maximum prescribed distances.

Generally, set joint areas should not exceed 20m2, with a maximum distance of 3.6m across the sheets and a maximum of 5.4m along the sheets.

1/3 Fixing

Garage Areas

Roller/tilt door operation can result in differential movement due to vibration resulting in positive joint cracking and adhesive breakdown/failure.

While the finish and appearance of these areas remains the same as ceiling in habitable areas additional details are required.

BGC Plasterboard recommends the use of Water Resistant Plasterboard with 1/3 fixings.

  • Screw and glue fix only.
  • Back block all joints.
  • Use of proprietary branded quality sealer prior to painting.
  • Use wet area base coats in jointing system.

Considerations

Before lining the building it is prudent to consider the following design and construction issues:

  • Consideration must be given to the framing, this may vary throughout Australia especially in high wind and coastal areas.
  • It is highly recommended to batten out the ceiling with Rondo 16mm metal battens or 16mm Furring Channel or 28mm Furring Channel or equivalent. These are to be fixed on the appropriate direct fix clips.
  • High-pressure differentials across a wall, may cause the wall to bend and move.

Ensure that wall and ceiling areas do not exceed maximum allowable areas, heights or lengths, and provide movement and or relief control joints where necessary.

  • Decoration is as important as the plasterboard installation and is vital in protecting both plasterboard and the set trowelled areas. The surface of the installed plasterboard ceiling should be decorated with an approved exterior grade paint. Please refer to your paint manufacturer for the appropriate grade required.

Back Blocking

Back blocking is used to reinforce unsupported butt or recessed joints and must be positioned midway between supporting members, in ceilings and walls.

Back blocking must be used in open areas of ceilings (back of recessed joints) with 3 or more joints and where there is a likelihood of excessive shrinkage and movement in the structure.

Black Blocking Procedure For Recessed Edge Joins

  1. Cut back blocks at least 200 mm wide and long enough to fit between the framing members with a gap not greater than 30 mm at each end.
  2. Apply BGC Back Blocking Cement over the full face of the back block. A notched spreader providing 6 mm × 6 mm beads at approximately 20 mm centres at right angle to the joint would be satisfactory.
  3. Fix the plasterboard to framing members.
  4. Place back blocks centrally along the full length of the board edge.
  5. Immediately after the back blocks are in place, fix the next sheet.

Alternatively, ceilings back blocks may be cemented into position from above the ceiling after the sheets have been fixed and before they are flush jointed.

 Back Blocking Procedure

Jointing Application

Paper tape joints produce stronger and more enduring results than those that are set with fibreglass tapes.

BGC Plasterboard recommends the use of paper tapes.

  • Self-adhesive paper tapes should not be used.
  • Where fibreglass tape joints are used, they must be back

blocked before the joints are set (in accordance with the instructions set out in Back Blocking, page 12).

Tape & First Coat

Apply the BGC Base Coat bedding cement to fully fill the
recess of the joint.

Centrally bed the perforated paper tape into bedding coat and remove any air bubbles. Apply additional cement and cover lightly with BGC Base Coat.

Stop-up all fixing points and apply BGC Base Coat to any damaged areas.

Allow the BGC Base Coat to set and dry for a minimum of 24 hours in damp or humid conditions or 1 hour for setting type cements (or as per compound manufacturer’s recommendation).

Second Coat

Lightly sand the first coat.

Check the Level of Finish required in the architects’ specification, before applying the second coat as detailed in Plasterboard Finish Selection (page 4).

Apply a second coat of BGC Base Coat 180mm wide over the joints, making sure to feather out the edges.

Apply a second coat to all fasteners and damaged areas, feathering out by about 25mm.

Allow the second coat to set and dry for a minimum of 24 hours or 1 hour for setting type cements (or as per compound manufacturer’s recommendation).

Third Coat

Lightly sand the second coat.

Apply a thin finish coat of BGC Top Coat centrally over second coat, after it has set and hardened. Dampen the outer edges of the finish coat, with a sponge to feather out the BGC Top Coat about 280mm approx wide.

Apply a thin final coat of BGC Top Coat over all fasteners and damaged areas.

Sanding and Finishing

Allow the BGC Top Coat to dry at least 24 hours.

Lightly sand smooth with 150 grit paper or with 220 sanding mesh.

Wipe off excess dust with a slightly damp cloth.

BGC Plasterboard will perform to the architects’ specification and the Australian Building Codes, provided all procedures are followed as per the compound manufacturers’ specification.

Decoration

BGC Plasterboard does not recommend spray painting to achieve level 4 or higher finish.

Ensure all stopping of joints and nail holes is completed to AS/NZ 2589:2007.

Brush down area prior to painting to ensure board is free from sanding dust.

Roller apply a proprietary branded quality sealer, to the entire sheet area including joints, followed by two coats of full weight flat acrylic paint.

Choice of colour should be considered carefully – darker colours will exacerbate any defects and highlight any imperfections.

Where high humidity is of concern, ensure the chosen painting system will protect joints from moisture absorption.

Cove Cornice

BGC Plasterboard Cove Cornice is designed to give a clean continuous line at the junction of walls and ceilings, and can be used with confidence on both Plasterboard lining and cement plastered walls alike.

BGC Plasterboard Cove Cornice is made of a plaster core with paper face to complement BGC Plasterboard and Ceilingboard. Cove Cornice should be fixed using BGC Cornice Cement with few special tools required.

The use of a mitre box and hand saw for cutting internal and external corner mitres is recommended.

Fixing

Clean down area where cornice is to be applied, remove any excess render or loose material.

Mark a guide line to suite the bottom edge of the cornice (90, 75 or 55 down) and pre-cut lengths as required.

All corner joints, internal and external, are to be mitred.

Where butt joints are unavoidable, ensure both ends are prepared to align accurately.

Apply (butter) a 10mm bead of cornice cement to both long edges and ends of the cornice.

Locate cornice to guide lines and temporarily block as required.

Fill mitres, cleaning off excess cement as you go.

Remove temporary blocking after BGC Cornice Cement has set.

Apply second topping coat to mitres and joints as required.

Note: only ever butter one length at a time and install immediately.

Contact surface may require damping down prior to fixing cornice, depending on drying conditions.

Impactboard Plasterboard

Specialty plasterboard that has fibreglass strands within the product and a heavier paper liner meaning the board is much stronger than standard plasterboard. Impactboard is suitable for use in very high traffic areas where walls are subjected to being knocked.

Features and Benefits

  • Specifically designed for high impact areas.
  • High resistance to soft body impact.
  • Reduced indentations from hard body impact.
  • Equivalent acoustic performance to BGC Soundboard.
  • Stronger that standard 13mm plasterboard.
  • Same installation method as standard plasterboard.
  • Easy to joint and finish.
  • Easy to repair.

Impactboard is suitable for both residential and commercial applications and is especially recommended for high traffic areas such as entrance foyers, corridors, waiting rooms and many more. Impactboard should be considered when lining areas where the wall linings are subject to a lot of passing human traffic or lots of movement of equipment or furniture.

Impactboard is ideally suited for commercial applications such as schools, hospitals, airports and shopping areas and in residential applications for hallways, rumpus rooms and games rooms.
