Protectosil® SH ensures the hardening of stones.

Protectosil® SH is used to deposit silicic acid formed as a result of complete hydrolysis. The resulting silicic acid bonds well to many mineral, inorganic substrates, such as natural stone, brick or terracotta stones. The deposition of a thin SiO2 layer improves chemical and thermal stability as well as mechanical properties.

In the case of porous mineral substrates Protectosil® SH is used for stone consolidation. Depending on the kind of natural stone Protectosil® SH is applied in specifically developed formulations as a silica source.
