Litokol StyleGrout Tech is a flexible cement-based grout, here in light grey. It comes as a powder in a 3 kg bag and is mixed with water. You can use it to grout ceramics, porcelain stoneware, mosaics, large slabs, and natural stone, on floors and walls, indoors and outdoors.
Color & Atmosphere
Grey-1 is a light and neutral grey, without warm or cool undertones. It's the most discreet choice for grey tiling.
Product & Application
StyleGrout Tech falls into class CG2WA according to EN 13888 and ISO 13007-3. This is an improved cement-based grout with reduced water absorption and high abrasion resistance. The joint remains full and smooth, and the product is formulated to prevent efflorescence.
- Ceramic tiles, porcelain stoneware, and single- or double-fired tiles
- Ceramic and glass mosaics
- Large format tiles and thin laminated stoneware slabs
- Marble, granite, natural stone, and reconstituted stone
- Terracotta and clinker tiles
- Wet rooms, showers, swimming pools, fountains, spas, and hammams
- Terraces, balconies, facades, and industrial floors
- Underfloor heating
Polished porcelain stoneware and natural stone often have micropores on the surface, which can cause the tile to discolor or be difficult to clean. The manufacturer recommends always making a test joint first in such cases.
Substrate & Compatibility
First, check that the tile adhesive is completely dry and cured. The joints must be clean, dust-free, and open across the full tile thickness, and any adhesive residue that has seeped into the joint should be removed. Remove plastic tile spacers before grouting; butt joints without space are not permitted.
- For highly absorbent tiles or in warm weather: moisten the joints first with a damp sponge
- Do not apply on damp surfaces or with rising damp
- Do not add lime, cement, or other materials to the product
- For expansion, corner, and connection joints, use an elastic sealant, not grout
For indoor work, allow for expansion joints every 20 to 25 m², and outdoors every 9 to 15 m². Outdoors, these joints must also be waterproofed.
Processing
First, put the water into a clean bucket and slowly add the powder while mixing with a drill and mixing paddle until a lump-free mixture is formed. Let the mixture rest for about 3 minutes, then mix again for a few more seconds. Manual mixing is not recommended.
- Approximately 0.8 liters of water per 3 kg bag, which is 26 to 28%
- Process between +5 °C and +35 °C
- Approximately 50 minutes working time at +23 °C
- Apply with a rubber float, diagonally to the joint direction
- After 15 to 30 minutes, as soon as the product becomes matt, wash off with a well-wrung sponge
Adhere to the water-mixing ratio: too much water leads to shrinkage and lower final strength, and different amounts of water between two batches will result in color differences in the final product. Do not wash off too early — if the product is still plastic, you will partially empty the joint and the color will be uneven. Adding water after bonding has begun is not allowed.
Remove haze after hardening with a clean cloth. If residues remain on the tile, they can be removed six to seven days after grouting with Litoclean or Litoclean EVO. Do not use these cleaners on non-acid-resistant materials such as marble or limestone. Protect the work from direct sunlight and strong drafts for the first 12 hours, and do not cover the fresh joint: wait 24 to 48 hours before covering it with breathable material.

Frequently Asked Questions
How much water goes into a 3 kg bag? Approximately 0.8 liters, which is 26 to 28%. Adhere to this: more water leads to shrinkage and lower final strength, and you will see color differences in the joint between two batches with different water-mixing ratios.
Why do I have to wait 15 to 30 minutes before washing off? As long as the product is still plastic, the sponge will partially empty the joint and the color will become uneven. Wait until the surface becomes matt, then wash off with a well-wrung sponge.
Can I use this grout on natural stone? Yes, marble, granite, and natural stone are listed in the technical data sheet. However, always make a test joint first, as porous stones can discolor. The cleaners Litoclean and Litoclean EVO are acidic and may not be used on marble or limestone.
When can the floor be used again? The work is loadable after 24 hours. For swimming pools, seven days must pass before the pool can be filled.
