Litokol Starlike® Pro in the color Pomice di Lipari (04) is a 6th generation decorative epoxy grout that combines aesthetics and technical performance at the highest level. The soft grey-beige hue of volcanic pumice, brought together in a color that transforms your tile or stonework into a finished whole. With 200 million colored quartz microspheres per kilogram and a water impermeability of ≤ 0.1 g (EN 12808-5), this product delivers both visual depth and uncompromising durability.
In brief
-
6th generation epoxy formula — two-component epoxy resin-based system provides adhesion that cement grout cannot match, ideal for long-term stressed surfaces such as bathroom floors and patios.
-
Waterproof: absorption ≤ 0.1 g (EN 12808-5) — moisture, mold, and bacteria have no chance; the grout remains fresh and hygienic for years without periodic impregnation.
-
Antimicrobial certified (ISO 22196) — active protection against bacterial growth and surface contamination, indispensable in kitchens, swimming pools, and care areas.
-
Working time > 90 minutes — ample open time for professionals and DIY enthusiasts to carefully finish large areas or complex patterns without time pressure.
-
HACCP/EC 852/2004 certified — suitable for direct contact with food and drinking water; used in professional kitchens, catering establishments, and swimming pools.
-
Temperature resistant from -20°C to +100°C — functions flawlessly on heated floors, in saunas, hammams, and on unprotected outdoor patios throughout all seasons.
Applications
Starlike® Pro Pomice di Lipari is designed for demanding environments where ordinary cement grout falls short. In the bathroom, it provides a waterproof, mold-free joint that lasts for decades — even on heated floors. On the outdoor patio, it withstands frost, UV radiation, and rainwater without discoloration or crumbling. In the swimming pool and hammam, the epoxy base offers maximum resistance to chlorine and water vapor. Professional kitchens and catering establishments benefit from the HACCP certification for hygienically responsible use. Also suitable for tiny houses, compact apartments, and guest toilets where every millimeter makes a visible design statement.
Design & color: Pomice di Lipari
The soft grey-beige hue of volcanic pumice. The color Pomice di Lipari (code 04) perfectly complements interior styles such as Wabi-Sabi, Scandinavian, and Natural Modern. Combine with concrete look, slate, bleached wood, sand for a cohesive interior picture that radiates both personality and sophistication. Concrete look bathrooms, industrial apartments, and spa suites are pre-eminently the spaces where this color shows its full potential. The quartz microspheres in the grout give the color a subtle depth that cannot be achieved with standard cement grout — the result is a finish that feels like a conscious design choice, not an afterthought.
Technical superiority
Where traditional cement grout remains porous and eventually darkens, fades, or crumbles, Starlike® Pro forms a closed, non-porous matrix after curing. The abrasion resistance of ≤ 250 mm³ (EN 12808-2) means that the grout is resistant to intensive foot traffic, hard-soled shoes, and industrial cleaning machines. Shrinkage is limited to ≤ 1.5 mm/m (EN 12808-4), making cracks and loose grout a thing of the past. The double certification as RG (EN 13888) and R2T (EN 12004) makes this product applicable as both grout and thin-bed adhesive, which makes it project-flexible for tiles, mosaics, and natural stone.
Tips for the best result
-
Preparation is everything: ensure the tile surface is completely dry, dust-free, and grease-free before you start. Use a pH-neutral cleaning agent and allow at least 24 hours to dry after removing any residues.
-
Correct mixing ratio: mix components A and B strictly in the provided ratio and use an electric mixer at a low speed (max. 300 rpm) for a homogeneous mixture without air bubbles.
-
Joint size 1–20 mm: Starlike® Pro is optimized for joint widths in this range. Before starting, check if your tile pattern and joint depth fall within this specification.
-
Clean quickly and thoroughly: remove excess grout within 30–45 minutes after application with a damp sponge and clean water. After full curing (24–48 hours), removal is considerably more difficult.
-
Underfloor heating: do not reactivate the heated floor until at least 48 hours after grouting. Then gradually increase the temperature to minimize thermal stress in the grout joint.

Frequently asked questions
Is Starlike® Pro Pomice di Lipari suitable for use on floors?
Yes. The abrasion resistance of ≤ 250 mm³ (EN 12808-2) and the shrinkage of ≤ 1.5 mm/m (EN 12808-4) make this product excellently suitable for floor applications, including high-traffic areas such as hallways, kitchens, and commercial environments.
Can I use this grout in combination with underfloor heating?
Absolutely. Starlike® Pro is temperature resistant up to +100°C and remains stable during the thermal cycles that a heated floor undergoes. Wait at least 48 hours after grouting before reactivating the heating.
How do I maintain a joint in Pomice di Lipari color?
Daily maintenance is sufficient with a damp cloth or a pH-neutral cleaner. Because the epoxy bond is non-porous, dirt does not penetrate the joint — periodic impregnation as with cement grout is not necessary.
Can Starlike® Pro also be used outdoors?
Yes. Its UV resistance and thermal shock resistance from -20°C to +100°C make the product suitable for terraces, facade cladding, and other outdoor applications in the Benelux climate.
What is the difference between Starlike® Pro and ordinary cement grout?
Cement grout is porous and susceptible to mold, stains, and discoloration. Epoxy-based Starlike® Pro forms a closed, non-porous matrix after curing that limits water absorption to ≤ 0.1 g and is chemically resistant according to class RG (EN 12808-3). The initial investment is higher, but the absence of periodic maintenance, regrouting, or impregnation makes it the more cost-effective choice in the long run.
