Silex® GLASS Micro-Crack & Pinhole Filler

Silex® GLASS Micro-Crack & Pinhole Filler is a proprietary formula designed for filling pinholes, micro-cracks and small voids within the substrate during the concrete grinding and polishing process.

This unique formulation combines our silicate technology that chemically reacts with the dust, creating a slurry that automatically fills imperfections while at the same time producing a harder more densely refined surface, increases surface tension and contributes to increased gloss levels.
