Litokol Starlike Pro is a sixth-generation decorative epoxy grout, here in the color Ardesia (10). 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 & ambiance
Ardesia (10) has the warm gray tone of slate. It subtly outlines the tile pattern without harsh contrast, beautiful with natural stone and darker stoneware.
Product & application
Starlike Pro is intended for joints from 1 to 20 mm, on floors and walls, indoors and outdoors. The cured grout is waterproof, stain-resistant, and UV-resistant. The color comes from colored quartz and glass microspheres instead of chemical pigments, which ensures stable color.
- 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 helps to determine if 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, 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 rather a sealant from the Pixel 3D line.
Processing
Cut open the bag of hardener and empty it completely into the bucket with component A. Mix with a slow-rotating mixer at approximately 300 rpm until a creamy, lump-free mass is formed, scraping the sides and bottom of the bucket as you go. Manual mixing is not recommended, as an uneven mixture affects the final strength.
- Process between +10 °C and +30 °C
- Over 90 minutes of processing time in the bucket
- Apply with the Starlike rubber grout float, diagonally to the grout direction
- Clean while the product is fresh, with white felt and then a damp sponge
- Light foot traffic 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 format, tile thickness, and joint width. Use the calculation tool on the product page or Litokol's consumption calculator. For adhesive, calculate 1.1 kg/m² with a 2 mm notch, increasing to 3.5 kg/m² with 10 mm.
Can I use this grout over underfloor heating? Yes. Underfloor heating is listed in the technical data sheet as an allowed substrate, and the cured 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 first for natural stone? Natural stone, mosaics, and polished stoneware vary greatly depending on origin and production. Litokol therefore prescribes a test joint, so you can see in advance if 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 you are working around that limit, Litokol recommends adding EpoxyGel booster: one 50-gram sachet per 2.5 kg, two sachets per 5 kg.
