Silicate concrete sealers penetrate into the surface of the concrete where they chemically react below the surface to form a permanent calcium silicate hydrate (CSH) barrier within the pores. Once cured, the CSH barrier will reduce the size of the concrete pores and increase the surface strength by up to 45%. By reducing the size of the pores, the movement of sub-surface water and moisture through the pores is also reduced. Concrete sealed with a silicate concrete sealer will be more resistant to dusting and deterioration caused by weak concrete or surface abrasion.
