Litokol Starlike Pro is a sixth-generation decorative epoxy grout, here in the color Argilla di Cipro (30). It is a two-component product: the colored gel and the polymeric hardener are together in one 2.5 kg bucket. You can grout tiles, mosaics, and natural stone with it, and the same product can also be used as tile adhesive.
Color & Ambiance
Argilla di Cipro (30) has the grey-brown tone of dried clay. With sandstone and travertine, the grout blends with the stone instead of standing out.
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, 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 helps determine if the material discolors or is difficult to clean.
Substrate & Compatibility
As a grout, apply Starlike Pro to joints that are dry and 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 particles, grease, oil, paint, wax, and rising damp, according to UNI 11493-1.
- Screeds, leveling compounds, and plasterwork
- Gypsum and anhydrite
- Concrete, aerated 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 of hardener and completely empty it into the bucket containing part A. Mix with a slow-speed mixer (approximately 300 rpm) until a creamy, lump-free mixture is obtained, scraping the sides and bottom of the bucket. Manual mixing is not recommended, as an uneven mixture affects the final strength.
- Process between +10 °C and +30 °C
- Over 90 minutes of pot life
- 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
- 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 when 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 aid on the product page or Litokol's consumption calculator. For 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 cured grout 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 should I do a test first with natural stone? Natural stone, mosaics, and polished stoneware vary greatly depending on their origin and production. Litokol therefore recommends a test joint to determine in advance if the surface discolors or is difficult to clean.
What if the temperature is colder than 10 degrees? Do not apply the product when 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.
