In short
-
6th generation epoxy formula — two-component system based on epoxy resin provides adhesion that cement grout cannot match, ideal for long-term stressed surfaces such as bathroom floors and terraces.
-
Waterproof: absorption ≤ 0.1 g (EN 12808-5) — moisture, mold, and bacteria stand 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, essential in kitchens, swimming pools, and care facilities.
-
Working time > 90 minutes — ample open time for professionals and DIY enthusiasts to carefully complete 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 terraces throughout all seasons.
Applications
Starlike® Pro Terra di Volterra 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 terrace, it withstands frost, UV radiation, and rainwater without discoloration or crumbling. In swimming pools and hammams, the epoxy base offers maximum resistance to chlorine and water vapor. Professional kitchens and catering establishments benefit from HACCP certification for hygienically sound use. Also suitable for tiny houses, compact apartments, and guest toilets where every millimeter makes a visible design statement.
Design & color: Terra di Volterra
The rich, earthy brown color of Tuscan terracotta soil. The color Terra di Volterra (code 22) perfectly matches interior styles such as Rustic Italian, Mediterranean Warm, Country Luxe. Combine with warm brown wood, terracotta, bronzed copper, natural stone for a cohesive interior picture that exudes both personality and sophistication. Tuscan villa, rustic bathroom, rural holiday home 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 can withstand intense foot traffic, hard-soled shoes, and industrial cleaning machines. Shrinkage is limited to ≤ 1.5 mm/m (EN 12808-4), making cracks and loose joints a thing of the past. The dual 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, mosaic, 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 exclusively in the provided ratio and use an electric mixer at low speed (max. 300 rpm) for a homogeneous mass without air bubbles.
-
Joint size 1–20 mm: Starlike® Pro is optimized for joint widths in this range. Check before starting whether your tile pattern and joint depth fall within this specification.
-
Clean quickly and thoroughly: remove excess grout within 30–45 minutes of application with a damp sponge and clean water. After full curing (24–48 hours), removal is significantly more difficult.
-
Underfloor heating: do not restart the heated floor until at least 48 hours after grouting. Then gradually increase the temperature to minimize thermal stress in the joint area.

Frequently asked questions
Is Starlike® Pro Terra di Volterra suitable for use on the floor?
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 suited 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 switching the heating back on.
How do I maintain a joint in Terra di Volterra color?
Daily maintenance with a damp cloth or a pH-neutral cleaner is sufficient. 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 applied outdoors?
Yes. The 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. Starlike® Pro, based on epoxy, 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, re-grouting, or impregnation makes it the more cost-effective choice in the long run.
