Cementitious colored grout with selected quartz aggregates, for grouting tile and marble, reinforced with special acrylic polymer resins.
The resulting finish surface is vitreous/porcelain-like and water repelling, while it does not allow for the accumulation of dirt and bacteria. It applies easily and cleans rapidly, presenting exceptional color stability and uniformity. It is resistant to both moisture and abrasion.
Classified CG2/WAr per EN 13888.


It is suitable for grouting widths from 0-3mm, both indoors and out (pic.2-5), wall and floor surfaces lined with ceramic tiles, marble, polished and honed granite as well as glass mosaic (pic1), as well as wherever the aesthetics of the space or lining requires ultra smooth joints.


1. Surface preparation
Remove from the tile surface all adhesive residues and clean the grout joints with a damp sponge. For outdoor areas, it is recommended that on every 16-20m², we create and prime the expansion joints with PRIMER-PU and after 2-3 hours, we apply the elastomeric polyurethane sealant DUROFLEX-PU to fill them out.
Also, both indoors and out, the creation of perimeter expansion joints, 5-8mm wide, is strongly recommended. Create expansion joints between tiles and vertical surfaces, and fill in the same way as described above, thus reducing the compression of the joints from expansions and contractions.
Alternatively apply DS-POLYMER, available in 32 shades (same with the grout colors of DUROSTICK), to ensure sealing without cracking at the junction of the tiles with the skirting and above it as well. For floors with radiant heating, it is recommended to create expansion joints every 20m². Use DS-POLYMER, available in 32 colors, to prevent the appearance of hairline cracks on the surface of the grouting material, and the consequent detachment of tiles.
2. Application
Empty the powder into a clean container with cool water, at a ratio of 1.5-1.6lt of water to 5kg of powder, and mix with a low speed electric mixer, until a lump free, homogenous mass is created.
Allow the mixture to mature for 5-10 minutes and mix periodically, without adding extra water. Apply the grout using a grouting float working diagonally towards the grout joints, without leaving any gaps or residue. When the grout begins to set, remove the residue using a damp sponge. Finally, when the material cures completely, clean/shine the surface with a dry cotton cloth. The addition of DUROSTICK ACRYLIC EMULSION in the mixing water, at a ratio of two parts water to one part emulsion, increases its impermeability and resistance to temperature variations (balconies, terraces, radiant heating). If a bigger degree of flexibility is required, then use the DUROSTICK FLEXIBLE & OIL REPPELENT grout, for tiles and marble.


• Avoid grouting at temperatures above 35°C when the surface is exposed to sunlight thus preventing cracking. If this is unavoidable, cover with wet burlap or polystyrene panels the still fresh grouted surface.
• Allow 20 days to pass before cleaning all debris and grout residues, using the DUROSTICK ACID TILE CLEANER, but only when the tiles are not absorbent.


DUROSTICK grouts are available in a variety of colors able to meet every styling requirement in relation with the lining. Furthermore, it is possible to color the DUROSTICK grouts, using the DUROCOLOR POWDER-C system. Color the white grouts based on the existing color chart or experiment creating unique colors or shading combinations.


Clean all tools with water, immediately after use.
