Litokol StyleGrout Tech is a flexible cement-based grout, here in black. It comes as a powder in a 3 kg bag and is mixed with water. It can be used to grout ceramics, porcelain stoneware, mosaics, large slabs, and natural stone, on floors and walls, both indoors and outdoors.
Color & Atmosphere
Black-1 is black with a gray undertone, not jet black. With anthracite tiling, it keeps the lines clean without stark contrast.
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
- Wet rooms, showers, swimming pools, fountains, spas, and hammams
- Terraces, balconies, facades, and industrial floors
- Underfloor heating
With polished porcelain stoneware and natural stone, there is often microporosity in the surface, which can cause the tile to discolor or be difficult to clean. The manufacturer advises 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 over the full tile thickness, and any adhesive residue that has seeped into the joint must be removed. Plastic tile spacers must be removed before grouting; butt joints without space are not permitted.
- For highly absorbent tiles or in hot weather: moisten the joints first with a wet sponge
- Do not apply to damp substrates or in case of 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 interior work, allow for expansion joints every 20 to 25 m², and for exterior work, every 9 to 15 m². Outdoors, these joints must also be finished to be watertight.
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 mass is formed. Let the mixture rest for approximately 3 minutes and then mix again for a few 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 of working time at +23 °C
- Apply with a rubber float, diagonally to the direction of the joint
- After 15 to 30 minutes, as soon as the product becomes matte, wash off with a well-wrung sponge
Adhere to the water mix ratio: more water causes shrinkage and lower final strength, and different amounts of water between two batches will result in color differences in the final result. Do not wash too early — if the product is still plastic, you will partially empty the joint and the color will be uneven. Do not add water after the bond has begun.
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 placing breathable material over it.

Frequently Asked Questions
How much water goes into a 3 kg bag? Approximately 0.8 liters, which is 26 to 28%. Please adhere to this: more water causes shrinkage and lower final strength, and different water amounts between two batches will result in color differences in the joint.
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 matte, 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 stone types can discolor. The cleaners Litoclean and Litoclean EVO are acidic and should NOT be used on marble or limestone.
When can the floor be used again? The work is trafficable after 24 hours. For swimming pools, allow seven days before filling the pool.
