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 to effectively remove acidic particle remains from the joints before commencing grouting.Substrate temperature must between 60°F (16°C) and 90°F (32°C).

Mixing:

Stir DUROMIX Polymer admix thoroughly before use. Use approximately 3.75 liters of water or DUROMIX for 10 kg of DUROPOX - 99 Grout powder. Place water or 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 of Water should be used for mixing with grout powder for best results.

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

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.

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. When water is used for mixing with grout powder, non-absorbent tiles will have lesser demand of water to be mixed. It is estimated in the range of 3.30 Litres to 3.70 Litres for 10 Kg grout powder. For better color retention, flexibility and water resistance, use DUROMIX Polymer admix completely replacing water/a part of water

Coverage:

Please refer the coverage chart as it depends on the tile size, ioint width and depth.

Limitations:

Consult with Technical Services for specific exterior grouting recommendations. For industrial applications exposed to high concentra­ tions of food and mineral acids and to high heat, use DUROPOXY- l5K Epoxy Grout. Protect from exposure to acids and strong cleaners during service periods. Acidic cleaners can neutralize the cement-based grouts which leads to change of colour, cracking and powdering Not recommended for soft, polished marble or delicate glazed tiles.
