Formulated for Porous Block

Iso-Tek™ 8555 is a deep penetrating, silane/siloxane water repellent specially formulated for porous block. Once applied the change of the surface tension creates a surface environment that is hydrophobic forming an effective shield that aides in a dramatic reduction of chloride and water absorption. It eliminates problems caused by efflorescence, leaching, acid rain, deterioration, scaling, staining, and corrosion of steel reinforcement.

Reduces Water & Chloride Absorption

Easily applied with a sprayer, roller or brush, the 8555 is specifically formulated for porous substrates such as cinderblock, CMU block, split-face, fluted, or ground-faced blocks. Can be used on interior and exterior substrates, on new and old concrete and any surface made of concrete, brick, masonry and natural stone.
