ECO.CALIBRE Concrete Protect is a truly remarkable, easy to apply and environmentally-friendly building material based on innovative silicate technology. It is one of the highest performance forms of liquid glass, known in Germany as “Kalium Wasser Glass”.

 

ECO.CALIBRE Concrete Protect penetrates deeply (some 3mm – 4mm) below the surface, reacting with the calcium present in the substrate to form an incredibly hard silicate structure that reinforces stone, masonry and concrete. It closes the pores and protects the surface with an extremely high resistance to chemical attack and abrasion. Treated surfaces are waterproof but remain breathable.

 

Suitable for all types of absorbent mineral substrates such as concrete, paving stones, floor screed, sand and cementitious materials, ECO.CALIBRE Concrete Protect is odourless, free from solvents and easy to use. The coating dries out over 10-15 year and is permanent. Suitable for indoor and outdoor use, it performs best in cementitious products with high calcium content. In particular, because it is an impregnating, hydrophobic sealer it also protects porous building materials such as brick, tiles, concrete and paving against efflorescence.

 

Compared to ECO.CALIBRE Rainoff HO, It provides extra protection outdoors where freeze-thaw cycles may be a significant issue.
