Penetrating water-base sodium silicate solutions harden and densify concrete by chemically reacting with the calcium salts present in concrete. It can be applied in one coat or multiple coats depending on the concrete porosity and can be used on either new or existing concrete floor. Sealers actually penetrate into the concrete surface to a depth of about 1 to 4 mills to increase water repellency and resist stains on absorbent concrete.
They provide invisible protection without changing the surface appearance, and can increase the surface strength of your concrete floor. Film forming solvent and water based acrylic sealers inhibit penetration of water and contaminants such as oil, grease, and stain by forming a barrier on the concrete surface. When used on newly placed concrete, sealers can help protect against spalling, dusting, efflorescence, freeze-thaw damage, and alkali degradation. Many also impart a gloss or sheen, so they often are used to enhanced colored, stamped, or exposed aggregate concrete.
