Siloxa-Tek 8505 is an advanced, high performance, industrial strength water based concrete/masonry water and oil repellent solution designed to reduce water and moisture intrusion. This unique formula incorporates leading molecular nanotechnology; putting an end to water, oils, fluids and moisture migration through any porous cementitious substrate. Siloxa-Tek 8505 is a uniquely transparent, blended formula with added enzymes and surfactants that aide in accelerating a penetrating disbursement. It provides a hydrophobic barrier beneath the surface and seals out moisture while remaining highly vapor permeable and chemically bonding with the substrate. The treated surfaces will show no change in visual appearance from application and the surface will not chip, flake, delaminate or breakdown with UV light exposure.
