Litokol Starlike Pro is a sixth-generation decorative epoxy grout, here in Nero Antico (12) color. 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
Nero Antico (12) is black with a gray undertone, not ink-black. With anthracite tiling, it keeps the lines sharp; with white tiles, it becomes a grid.
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 keeps the color stable.
- Ceramic and glass mosaic, 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, mosaic, and porous surfaces, the manufacturer specifies always making a test joint first. This determines whether the material discolors or is difficult to clean.
Substrate & Compatibility
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 separating membranes
For the elastic sealing of expansion, control, and connection joints, do not use epoxy grout but a sealant from the Pixel 3D range.
Processing
Cut open the hardener bag 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 wall 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 processing time in the bucket
- Apply with the Starlike rubber float, diagonally to the joint direction
- Clean as long as 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 residue 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.
Key Features
- Grout and glue with the same product: joints from 1 to 20 mm, adhesive layers from 1 to 10 mm
- Waterproof and shrink-free, even under permanent water load
- Resistant to temperatures from −20 °C to +100 °C
- Color-stable due to colored quartz and glass microspheres instead of pigments
- Part A and part B pre-dosed in one bucket, so no weighing
- Can be mixed with Starlike Finishes for a glitter or metallic effect, indoors only

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 should calculate 1.1 kg/m² with a 2 mm notch, increasing 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 for natural stone first? Natural stone, mosaic, and polished stoneware vary greatly depending on origin and production. Litokol therefore prescribes a test joint, so you can see 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 working around that limit, Litokol advises adding EpoxyGel booster: one 50-gram sachet per 2.5 kg, two sachets per 5 kg.
