Waterproof Sealers

When water's getting into concrete, brick or sandstone, surface coatings only buy you time. This range of waterproof sealers works from the inside — penetrating porous substrates to block moisture pathways, harden the surface and stop efflorescence before it starts.

From polyester-polymer treatments that pass negative hydrostatic pressure to siloxane-based invisible sealers that let the substrate breathe, each product in this range is built for a different exposure and substrate condition. Low-voc water-based options sit alongside solvent-based formulations for dense or trafficked surfaces — match the chemistry to the job and you'll get lasting protection without a film to peel or flake.
