Colloidal silica densifier concentrate designed to penetrate into most unsealed cementitious surfaces to densify, harden, and increase the strength of the top layer of a substrate while retaining its breathability. 

Ideal for sealing commercial and residential concrete floors such as distribution center floors, factory floors, warehouse floors, automotive garage floors, retail store floors, pole barn and shed floors, workshop floors, basement floors, garage floors, and other machine troweled, burnished, or polished concrete surfaces. It can also be used on low lime decorative concrete overlay products, integrally colored concrete, and is compatible with most dyes and stains.

“An electrostatically charged stable dispersion of 99.5% pure silica nanoparticles in an ultra low surface tension liquid solution. The low viscosity and 4-8 nm particle size allow it to penetrate deeply into a concrete surface.” -Retrieved 12/3/2024 from https://www.concretesealersusa.com/ps112-colloidal-silica-densifier-wb-penetrating-sealer-1-gal/
