WP350 Waterproofing Balconies with Acoustic Underlay
Preparation:
- All surfaces to be waterproofed must be firm, clean, dry, sound and smooth. All grease, oil, wax, curing compounds, loose material, paint and any other contaminants must be removed, masonry surfaces must be pointed flush and surface defects repaired. New concrete must be cured for a minimum of 28 days.
- External corners to be waterproofed must be bevelled to ensure a smooth transition of membrane from vertical to horizontal surfaces.
Installation:
- Waterproofing installation shall be in accordance with AS 4654.2 Waterproofing membrane systems for exterior use – Above ground level – Design and installation. Tile installation shall be in accordance with AS 3958.1 Ceramic Tiles – Guide to the installation of Ceramic Tiles.
- Install ACS Screed or an appropriate pre-blended bagged screed where required, to achieve appropriate falls to waste. Where a bonded screed is required, apply a bond coat using TPA 401M or TPA Lite.
ACS Screed is a pre-blended screed mixture for the installation of cementitious screeds and beds.
- Install Vibramat Acoustic Underlay with RLA RL1000 Adhesive.
Vibramat Acoustic Mat is an acoustic underlay made from recycled tyres and waste rubber.
RLA RL1000 is a single-part, VOC-compliant isocyanate-free water resistant resilient flooring adhesive.
- Apply WPA 200, WPA 230UV, WPA 400, WPA 500 or WPA Rapid membrane in a minimum of two coats to achieve the required dry film thickness. Ensure that the previous coat has completely dried before applying the subsequent coat(s).
WPA 200 is a flexible, two-part, rapid-drying, cementitious waterproofing membrane system, specifically designed for use under tile, stone and exposed applications.
WPA 230UV is an elastomeric, fibre-reinforced, water-based polyurethane membrane system designed for exposed or under-tile applications.
WPA 400 is an elastomeric, fibre-reinforced waterproofing membrane based on high-performance polymer technology designed for use under tile finishes.
WPA 500 is a waterborne, fibre-reinforced, flexible waterproof membrane designed for use under tile finishes.
WPA Rapid is a fast-curing, waterborne flexible waterproof membrane designed for use under tile finishes.
- Install tiles using TPA 401M, TPA 501R or TPA Lite tile adhesive.
TPA 401M is a white, flexible, powdered adhesive for wall and floor applications.
TPA 501R is a cost-effective, high-coverage, flexible, powdered adhesive for wall and floor applications.
TPA Lite is a premium grade, white, fibre-reinforced, flexible cement-based tile adhesive, based on a lightweight formulation. - Grout tiles using TPA Tru Colour Grout or an approved alternative.
TPA Tru Colour Grout is a high-performance stain & efflorescence resistant grout. It is designed for use with most types of Ceramic, Mosaic, Natural Stone and Glass Tiles.
- Install backing rod to all perimeter and intermediate movement joints and seal with TPA Tru Colour Sanitary Silicone or approved alternative.
TPA Tru Colour Sanitary Silicone is a mould-resistant, non-diluted, high-performance, UV-resistant, neutral cure silicone sealant.
