Cementitious colored grout with selected quartz aggregates, reinforced with special acrylic polymer resins.
The resulting finish surface of the grout 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, having exceptional color stability and uniformity. It is resistant to both moisture and abrasion.
Classified CG2/WAr per EN 13888.


It is suitable for grouting at widths from 1-10mm, both indoors and out, wall and floor surfaces lined with ceramic tiles, granite and mosaic.
It is suitable to apply on heavy traffic areas (airports, super markets, restaurants), as well as areas with permanent high moisture levels, such as bathrooms, balconies, terraces and kitchens.


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. To prevent the appearance of hairline cracks on the surface of the grouting material, and the consequent detachment of tiles, the creation of perimeter expansion joints, 5-8mm wide, is strongly recommended. Create expansion joints between tiles and vertical surfaces (plaster, skirting etc.) and fill it in the same way as described above.
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 indoor floors with radiant heating, it is recommended to create expansion joints every 20m².
The use of DS-POLYMER, available in 32 shades, will 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
1.1-1.4lt 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 (pic. 2).
When the grout begins to set, remove the residue using a damp sponge (pic. 3). Finally, when the material cures completely, clean/shine the surface with a dry cotton cloth (pic.4). 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 FLEXIBLE & OIL REPPELENT grout of DUROSTICK, 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 wet grouted surface.
• When working with rustic or absorbent cotto (terracotta) tiles, apply 2 coats of the waterproofing and oil repelling product, DUROSTICK D-29 SPOT FREE, to avoid staining from the residues of the grout. For the application, use the ‘wet-on-wet’ method.
• It is recommended to clean any grout residues, using the DUROSTICK ACID TILE CLEANER, but only after 20 days have passed from the grouting of the surface.


Store in tightly closed packages, in dry and shaded places for at least 12 months after production date.


Clean all tools with water, immediately after use.


The product contains Portland cement. Before using, refer to the cautions on the product packaging or the Material Safety Data Sheet.


Carton box with 4 pcs. of 5kg each one, on 1,000kg pallet.


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.


The following table is the indicative consumption, depending on the width and the depth of the joint, as well as the dimensions of the tiles.
