ProBlock – Pre Sealer

Aqua Mix® ProBlock – Pre Sealer for porous stone & tile is an economical, natural look, breathable sealer. It is a water based penetrating pre sealer designed to resist staining caused by water soluble minerals (including picture framing effect) which are normally absorbed through the back of the stone during installation. It also helps resist efflorescence migration. ProBlock is not an adhesive bond breaker.
