Litokol Starlike Pro is a sixth-generation decorative epoxy grout, here in color Terra Fumicata (31). It is a two-component product: the colored gel and the polymeric hardener are together in one 2.5 kg bucket. You can use it to grout tiles, mosaics, and natural stone, and the same product can also be used as tile adhesive.
Color & Atmosphere
Terra Fumicata (31) is smoked brown, with more gray than red in it. It provides a calm frame for dark natural stone and smoked oak look.
Product & Application
Starlike Pro is intended for joints from 1 to 20 mm, on floors and walls, indoors and outdoors. The hardened joint is waterproof, stain-resistant, and UV-resistant. The color comes from colored quartz and glass microspheres instead of chemical pigments, ensuring color stability.
- Ceramic and glass mosaics, ceramic tiles, and porcelain stoneware
- Large-format tiles and laminated stoneware slabs
- Marble, granite, natural stone, and reconstituted stone
- Terracotta and clinker
- Wet rooms, bathrooms and showers, swimming pools and fountains, spas and hammams
- Terraces, balconies, facades, and industrial floors
For natural stone, polished porcelain stoneware, mosaics, and porous surfaces, the manufacturer recommends always making a test joint first. This determines whether the material discolors or is difficult to clean.
Substrate & Compatibility
When used as a grout, Starlike Pro should be applied to joints that are dry, dust-free, and open for at least two-thirds of the tile thickness. If used as an adhesive, the substrate must be load-bearing and free of loose parts, grease, oil, paint, wax, and rising damp, according to UNI 11493-1.
- Screeds, leveling compounds, and plasterwork
- Gypsum and anhydrite
- Concrete, cellular concrete, and fiber cement boards
- Existing tiles, metal, and wood
- Underfloor heating, waterproofing systems, and separation membranes
For the elastic sealing of expansion, control, and connection joints, do not use epoxy grout but a sealant from the Pixel 3D line.
Processing
Cut open the bag with hardener and empty it completely into the bucket containing part A. Mix with a slow-rotating mixer (approx. 300 rpm) until a creamy, lump-free mass is formed, scraping the sides and bottom of the bucket. Mixing by hand is not recommended, as an uneven mixture affects the final strength.
- Process between +10 °C and +30 °C
- More than 90 minutes working time in the bucket
- Apply with the Starlike rubber trowel, diagonally to the joint direction
- Clean while the product is fresh, with white felt and then a damp sponge
- Lightly walkable after 24 hours, fully in use after 5 days, swimming pools after 7 days
Remove residues within 24 hours and no later than 48 hours from the tile surface, using Starlike Care for floors or Starlike Wall Care for walls. After that, the product can only be removed mechanically. Do not apply anything if the temperature drops below +10 °C within 24 hours, and protect the work from direct sunlight and strong drafts for the first 12 hours.

Frequently Asked Questions
How much Starlike Pro do I need? Consumption depends on the tile format, tile thickness, and joint width. Use the calculation tool on the product page or Litokol's consumption calculator. As an adhesive, calculate with 1.1 kg/m² for a 2 mm notch, increasing to 3.5 kg/m² for 10 mm.
Can I use this grout over underfloor heating? Yes. Underfloor heating is listed in the technical data sheet among the permissible substrates, and the hardened grout is resistant from -20 °C to +100 °C. Do observe the normal waiting times: 24 hours for light foot traffic and 5 days for full use.
Why do I need to do a test for natural stone? Natural stone, mosaics, and polished stoneware vary greatly in origin and production. Litokol therefore prescribes a test joint so that you can see in advance whether the surface discolors or is difficult to clean.
What if it's colder than 10 degrees? Do not process the product if the temperature drops below +10 °C within 24 hours. If working around that limit, Litokol advises adding EpoxyGel booster: one 50-gram sachet per 2.5 kg, two sachets per 5 kg.
