Litokol Starlike Pro is a sixth-generation decorative epoxy grout, here in the color Arenaria (35). It is a two-component product: the colored gel and the polymer 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
Arenaria (35) is light sandstone, with a soft orange glow. It suits warm natural stone and Mediterranean tiled floors.
Product & Application
Starlike Pro is designed 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 keeps the color stable.
- 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 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, in accordance with 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 decoupling membranes
For the elastic sealing of expansion, control, and connection joints, an epoxy grout should not be used, but rather a sealant from the Pixel 3D line.
Processing
Cut open the hardener bag and empty it completely into the bucket containing part A. Mix with a slow-speed mixer (approximately 300 rpm) until a creamy, lump-free mixture is formed, scraping the sides and bottom of the bucket as you go. Manual mixing is not recommended, as an uneven mixture can impair the final strength.
- Process between +10 °C and +30 °C
- Working time of over 90 minutes in the bucket
- 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 this, the product can only be removed mechanically. Do not apply 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 required
- 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 tile size, 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 approved substrate, 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 for natural stone? Natural stone, mosaics, and polished stoneware vary greatly by origin and production. Litokol therefore recommends a test joint to determine in advance if the surface will discolor or be 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.
