Litokol Starlike Pro is a sixth-generation decorative epoxy grout, here in the color Pomice di Lipari (04). 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
Pomice di Lipari (04) has the soft, slightly grayish tone of pumice stone. It gives light tiles a warm base instead of a harsh white line.
Product & application
Starlike Pro is intended for joints from 1 to 20 mm, on floors and walls, indoors and outdoors. The cured joint is waterproof, stain-resistant, and UV-resistant. The color comes from colored quartz and glass microspheres instead of chemical pigments, which ensures stable color.
- Mosaic of ceramic and glass, 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, spa and hammam
- 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 way you can determine if the material discolors or is difficult to clean.
Substrate & compatibility
As a grout, Starlike Pro is applied to joints that are dry and dust-free and open for at least two-thirds of the tile thickness. If you use it as an adhesive, the substrate must be load-bearing and free of loose parts, grease, oil, paint, wax, and rising damp, in accordance with UNI 11493-1.
- Screeds, leveling layers 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 with part A. Mix with a slow-rotating mixer of approximately 300 rpm until a creamy, lump-free mass, scraping the sides and bottom of the bucket afterwards. Manual mixing is not recommended, as an uneven mixture affects the final strength.
- Process between +10 °C and +30 °C
- Processing time in the bucket is over 90 minutes
- Apply with the Starlike rubber float, 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 from the tile surface within 24 hours and no later than 48 hours, 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 size, tile thickness, and joint width. Use the calculation tool on the product page or Litokol's consumption calculator. As an adhesive, you can expect 1.1 kg/m² with a 2 mm notch, rising to 3.5 kg/m² with a 10 mm notch.
Can I use this grout over underfloor heating? Yes. Underfloor heating is listed in the technical data sheet among the permissible substrates, and the cured joint is resistant from −20 °C to +100 °C. However, 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 first for natural stone? Natural stone, mosaics, and polished stoneware vary greatly depending on origin and production. Litokol therefore prescribes a test joint to determine in advance whether the surface discolors or is difficult to clean.
What if it is colder than 10 degrees? Do not process the product if the temperature drops below +10 °C within 24 hours. If you are working around that limit, Litokol advises adding EpoxyGel booster: one 50-gram sachet per 2.5 kg, two sachets per 5 kg.
