SURFACE PREPARATION

Ensure all areas are clean, dry, and free from dust or any other contaminating barriers. Remove any flaking or peeling layers. Background surfaces must be free from movement.

Skim Plaster: Ensure the plastered surface is fully cured and dust free, 14-28 days depending on temperature (with >0.5% moisture) prior to application.

Plaster Board: Ensure the boards are firmly fixed in place, securing any areas of deflection.

Concrete/Anhydrite type floors: Ensure the surface is fully cured and dust free with readings less than 75% humidity. All surface laitance must be removed prior to application.

Note: Moisture sensitive backgrounds should be protected from moisture ingress from behind.

APPLICATION
UltraTile ProAqua Shield should be applied using a brush or short pile roller to give a continuous thin layer of product at least 0.8mm thick. See application method. Drying time will be extended depending on thickness applied, porosity of background and temperature if less than 20°C.

APPLICATION METHOD

1) Apply coating to the junctions between wall to floor and wall to wall corners using a paint brush at coverage 1.1 kg / sq./m.

2) Bed a strip of membrane tape into the coating while still wet to strengthen and reinforce the junction points (adjoining boards). Tape can also be used to reinforce cracks, pipe entries and screw fixings.

3) When dry (after 30 minutes), apply one uniform coat over the complete wall and floor area including reinforced areas in a continuous layer at a coverage of 1.1 kg / sq./m using a paint brush or roller as previous. Allow 90 minutes drying time before commencing tiling.

TILING
Wall tiles should be fixed using UltraTile C2, S1 or S2 cement-based tile adhesive.
Floor tiles should be fixed using UltraTile C2, S1 or S2 cement-based tile adhesive.

Note: The use of dispersion adhesives may significantly extend drying times/ incomplete drying of the dispersion adhesive, depending on the tile type used.

CLEANING
Tools should be thoroughly cleaned with water to remove excess material immediately after use.
