In short
-
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 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, indispensable in kitchens, swimming pools, and healthcare areas.
-
Working time > 90 minutes — ample open time for professionals and DIY enthusiasts to finish large areas or complex patterns carefully and 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 through all seasons.
Applications
Starlike® Pro Nero Antico 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 outdoor terraces, it resists 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: Nero Antico
Deep antique black — maximum drama, minimal tiles needed. The color Nero Antico (code 12) pairs excellently with interior styles such as Art Deco, Dark Luxury, Modern Maximalist. Combine with gold-colored brass, white marble, black granite, copper for a coherent interior picture that exudes both personality and sophistication. Luxury black bathrooms, art deco toilets, high-end hotel rooms are precisely 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 over time darkens, fades, or crumbles, Starlike® Pro forms a closed, non-porous matrix after hardening. 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 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, 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 starting. Use a pH-neutral cleaner and allow at least 24 hours to dry after removing any residue.
-
Correct mixing ratio: mix components A and B strictly in the provided ratio and use an electric mixer at low speed (max. 300 rpm) for a homogeneous, bubble-free mass.
-
Joint size 1–20 mm: Starlike® Pro is optimized for joint widths in this range. Before starting, check that 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 complete curing (24–48 hours), removal is significantly 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 stresses in the grout surface.

Frequently asked questions
Is Starlike® Pro Nero Antico suitable for floor use?
Yes. The abrasion resistance of ≤ 250 mm³ (EN 12808-2) and the shrinkage of ≤ 1.5 mm/m (EN 12808-4) make this product excellent for floor applications, including high-traffic areas such as hallways, kitchens, and commercial environments.
Can I use this grout with underfloor heating?
Absolutely. Starlike® Pro is temperature resistant up to +100°C and remains stable during the thermal cycles of a heated floor. Wait at least 48 hours after grouting before reactivating the heating.
How do I maintain a Nero Antico colored joint?
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. Starlike® Pro, being epoxy-based, 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.
