WP800 Waterproofing – Window and Door Reveals

1. 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.
2. External corners to be waterproofed must be bevelled to ensure a smooth transition of membrane from vertical to horizontal surfaces.

Installation:

1. Repair all surface defects on masonry surfaces with an appropriate repair mortar.
2. Install an appropriate fillet (bond breaker) to all internal corners using WPA MS, WPA SPUR or Admil Supaseal Hybrid PU.

   WPA MS is a single-component, moisture-cured silane-modified hybrid sealant.

   WPA SPUR is a high-quality, professional, universal, low-modulus sealant based on hybrid technology.

   Admil Supaseal Hybrid PU is a low-modulus, Hybrid Polyurethane, flexible joint sealant and adhesive that is free of Isocyanates and other hazardous raw materials and omits low odour.

3. Apply WPA 460 or WPA 560 primer to the substrate to be waterproofed.

   WPA 460 is a two-part, water-based epoxy primer, used to seal concrete and masonry surfaces.

   WPA 560 is a two-part, water-based epoxy primer, designed as a water and vapour-proof coating under waterproofing membranes.

4. Apply WPA 230UV 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 230UV is an elastomeric, fibre-reinforced, water-based polyurethane membrane system designed for exposed or under-tile applications.

5. Allow the membrane to fully cure before installing the window system.
6. Seal the window system using WPA SPUR or Admil Supaseal Hybrid PU.
