Application Procedure

 

Substrates

WPA 230UV is suitable for concrete, render, screeds, block work, fibre-cement sheeting, wet area grade plasterboard, PPA certified structural and marine plywood and Scyon sheeting.

 

All Aluminium, PVC and other non-porous surfaces must be primed with WPA 160 All Purpose Primer.

 

Always contact the manufacturer if in any doubt about the suitability substrates.

 

Preparation

All surfaces to be waterproofed must be firm, clean, dry, sound and smooth. All laitance, grease, oil, wax, curing compounds, loose material, paint and any other contaminants which may reduce or prevent adhesion must be mechanically removed. Masonry surfaces must be pointed flush and surface defects repaired.

 

New concrete must be cured for minimum 28 days. All concrete must be completely dry and primed with WPA 360 water-based primer, WPA 460 or WPA 560 two-part water-based epoxy.

 

Render and cement screeds must be cured for minimum 7 days. Damp concrete, render or screeds must be allowed to thoroughly dry or primed with WPA 460 or WPA 560 two part water based epoxy.

 

Fibre cement sheeting, water resistant plasterboard, PAA structural and marine plywood and Scyon sheeting must be installed in accordance with the manufacturers’ installation requirements.

 

Install a bond breaker/fillet using Admil SupaSeal PU at all horizontal and vertical transitions. For optimal performance, incorporate WPA Elastoband at all transitions.

 

Static Crack Treatment

For cracks less than 1mm, clean cracks thoroughly before filling Admil SupaSeal PU. WPA 230UV cannot span gaps. For dynamic cracks/expansion joints and control joints, the use of WPA Elastoband system is recommended. Contact the WPA Technical Department for further advice.

Priming

Porous substrates must be primed with WPA 360 water based or WPA SB solvent-based primer. Damp substrates and Scyon sheeting must be primed with WPA 460 or WPA 560 two-part epoxy primer. Dense

substrates must be primed with WPA 160 All Purpose Primer.

 

All aluminium, PVC and other non-porous surfaces must be primed with WPA 160 All Purpose Primer.

 

Apply the primer to the prepared substrate by using a brush or roller in accordance with the relevant product’s Technical Data Sheet. Allow the primer to fully dry prior to commencing the application of WPA 230 UV.

Application

Prior to application, stir the contents thoroughly. Using a brush or roller, apply the first coat of WPA 230UV after the primer has sufficiently dried. Apply an even and consistent coat of approximately 0.75mm wet film thickness.

 

Once the first coat has dried, apply a second of WPA 230UV at right angles to the first coat. Apply an even and consistent coat of approximately 0.75mm wet film thickness.

 

WPA 230UV must be applied with a minimum of two coats to achieve a dry film thickness of not less than 1.0mm (1000 microns). Test the depth of coats with a wet film thickness gauge at regular intervals during installation.

 

Note: Avoid contact with skin and eyes. Wear splash proof goggles and rubber or PVC gloves at all times.

 

Performance Data and Physical Properties @23°C & 55% RH

  • Allow 2-4 hours between coats.
