Although concrete is one of the most durable man-made building materials, it is inherently porous, with many air pockets. The material will deteriorate over time unless a penetrating reactive sealer is applied to turn it into a usable and resistant floor finish.
Silicate-based sealers, including lithium silicates, sodium silicates, and fluorosilicates, have been used to improve the durability of concrete for decades, reducing porosity and increasing density to result in a surface that resists penetration of liquids, including oil and many chemicals.
