Aqualon S-400 is an environmentally friendly, VOC free, sodium silicate concrete floor densifier, hardener, and sealer which works by reacting with the free lime in the concrete. Aqualon S-400 is designed to penetrate and protect the surface by reducing porosity and dusting to improve abrasion resistance and hardness. The finished concrete surface is breathable and easier to maintain since it does not wear or peel away.
