Improved Cementitious grout with additional characteristics of reduced water absorption & high abrasion resistance

APPLICATION

Substrate preparation

Ensure to maintain 3 – 6 mm wide joints using spacers while fixing the tiles in position.

Immediately after setting the tiles & rake joints Clean to a uniform depth corresponding to the thickness of the tile. Allow bedding mortar to set.

Protect all connections and movement joints by inserting polystyrene profiles or foam sections. Remove polystyrene profiles prior to applying elastic sealants.

Mixing

Decide the gauging water in the range of 390 -450 ml per Kg of MasterTile 15, based on the consistency of mixed grout required, environmental conditions and open time warranted for the application.

Fill gauging water in a clean mixing container. Add powder and stir until a plastic, lump-free grout is achieved. Mixing shall be done using slow speed (300-500 rpm) mechanical stirrer.

Leave to stand for 5 minutes before using.

Apply to tile joints with a squeegee or rubber float. Fill joint flush with tile surface. Re-grout if necessary. Allow the grout to firm up in the joint (until it is resistance to thumb use thumb pressure) and scrap off excess grout with a slightly damp sponge or sponge board.

A grout film and/or pigment stains especially with very dark colours may remain on unglazed or matt glazed tiles after grouting. Follow the tile manufacturer's recommendations. A trial grouting might be recommendable. Remove any remaining haze carefully while still fresh. Joint have to be adequately pre-wet if acid-washing is necessary.
