A transparent, colourless wall coating, water and siloxane-based, ideal to protect porous walls of various substrates from wind-driven rain. After treatment, the wall is deeply impervious to water ingress and so better protected against frost damage. The treated wall will continue to dry and vapour drive is not effected due to the coating being very vapour permeable.
The resultant dry wall is much more thermally efficient and will save on heating bills also. Having a low molecular weight, Diasen BKK penetrates deeply into the substrate, creating an invisible but deep layer of protection that is extremely stable to lime and very permeable to water vapour.
