Surface Preparation:

Before starting to grout, remove debris in grout joints and lightly sponge the tile surface to remove dust and dirt. Do not clean tiles with acid cleaners. In case acid cleaners were used to clean the tiles, ensure to wash the area with plenty of water before commencing grouting. Substrate temperature must between 60°F (l 6°C) and 90°F (32°C).

Mixing:

Stir DUROMIX Polymer Admix thoroughly before use. Use approximately 2.5 liters of DUROMIX for l 0 kg of DUROPOX-99 Sandy Grout powder. Place DUROMIX in a clean mixing container and add grout powder slowly. Mix by hand or with a slow speed mixer to a smooth stiff consistency. Potable grade Water can also use with DUROMIX.

Dampen tile surface with water. Spread with a sharp, firm rubber grout float. Work the grout paste into the joints until completely filled. Use diagonal strokes to pack the joints. Ensure that joint is filled and grout is not just sitting on top (i.e. "bridging the joint")

Note: For fuller flush joints sprinkle a thin layer of dry grout powder over surface immediately after grouting. When grout darkens over joint, buff with burlap, carpet remnant or cotton rag to pack joint and clean face of tile.

Remove excess grout from the face of the tiles with the edge of the grout float. Hold the float at a 90° angle and pull it at a 45° angle diagonally across the joints and tile to avoid pulling out the material

Grout Secondary Cleaning :

Remove remaining grout with a damp sponge (not wet) or a damp towel. Work diagonally to the joints. Allow to dry. When the grout joints are firm polish the surface with a coarse nylon pad or coarse cloth and minimal water.

Note: Use caution when polishing soft glazed tiles or polished stone. Contact DUROXZ technical services for large format tile or stone installations on exterior surface

It is recommended to check the colour of the grout, if it is meeting the desired colour of the client. It is recommended to do a small area with actual tile/stone at site and check for any colour ingress into the tile/stone. Many tiles/ stones have high absorption which may lead to wet patches / discoloration / colour marks. Plan to provide proper movement joints, peripheral joints as per TCA, EJ 171 detail to accommodate movements in tile/stone and use flexible grout/ sealant to fill these movement joints. For better color retention, flexibility and water resistance, use DUROMIX Polymer Admix.
