Main highlights

Unique technology made in Germany: the stone seal SP5000 was developed by leading nano experts. StoneprotecT is based on a special molecular structure that penetrates the stone without sticking its interior. The stone impregnation guarantees preventive hydrophobization against green growth, moss infestation, lichens, dirt and frost damage, as well as easy cleaning of the treated surfaces.
RECOMMENDED BY LEADING NANOFACHPORTALS: If a stone surface is porous, dirt and water penetrate the stone capillaries. With the award-winning seal, you reduce the absorption of moisture and dirt on all absorbent, mineral surfaces. So the stone retains its high-quality look.
Many possibilities: ideal sealing for patios, balconies, walkways, facade, roof tiles, carport, as well as concrete, paving stone, clinker, travertine (open-pored) or sandstone – refreshing the effect at any time. Box contents: 2 x 5 litres for up to 100 m².
Environmentally friendly and non-toxic: the water-based, odourless impregnation is non-toxic for humans and animals. Free from PFAS and microplastic. The unique technology of the stone impregnator successfully reinforces resistance to external influences on surfaces and reduces dirt adhesion.
Easy to use: clean the stones thoroughly and then apply StoneprotecT evenly. Best results by using a pressure sprayer. After a drying time of approx. 30 minutes, the cleaned surface can be fully walked on and resilient. For pre-cleaning, we recommend the StoneprotecT products SPGREEN and SPBLUE.

Protection against water and dirt: If a stone surface is porous, dirt and water penetrate the stone capillaries and destroy the stone from the inside. The SP5000U sealant protects your stone by preventing the absorption of moisture and dirt. So the stone retains its beautiful look.
Nano technology made in Germany: the stone care product was developed by leading nano experts from Germany and the USA. So the stone impregnator penetrates the stone without sticking its interior. The moisture created in the stone can escape instead of freezing. Therefore, no stone quarries and running marks are risked.
Extremely economical: whether concrete slabs, paving stones, natural stone, granite, travertine, sandstone, tiles or marble, with the mixed concentrate all absorbent, mineral surfaces can be easily sealed. 1 litre concentrate mixed with 9 litres of water results in 10 litres of impregnation, with which you can impregnate 80-120 m².
Environmentally friendly and quick drying: the odourless impregnation is non-toxic for humans and animals as well as biodegradable. Clean the stones thoroughly. Then mix the concentrate with water in a 1:9 ratio and apply the seal. After a drying time of 45 - 60 minutes, the cleaned surface is fully walkable and resilient.
Easy post-treatment: unlike conventional stone sealants, the old layer of the natural stone impregnation does not have to be removed laboriously during a post-treatment. StoneprotecT fills the worn areas outdoors and can be easily reapplied. Free from PFAS.
