Crystal Sealer 5kg

A cement-based, waterproofing compound that chemically reacts with moist cement-based substrates. Crystal Sealer forms insoluble crystals in the capillary tracts of the substrate, permanently waterproofing the surface yet still allowing the surface to breathe.

Features
*Penetrates into and becomes a permanent. integral part of the surface, therefore it can not peel or blister off as do normal coatings.
*Will not tear or puncture and does not have to be protected from back fill.
*Being a cement based material, Crystal Sealer has an expansion and contraction the same as the cement surface to which it is applied.
*Crystals can grow up to 0.4 metres into the concrete in the presence of water. Crystals grow approx. 1cm depth per week.
