With numerous choices facing anyone who wishes to purchase a concrete sealer, it is imperative that you narrow down your choices by general type of sealer. For many applications, silane/siloxane sealers are flexible options that provide excellent coverage and protection of numerous types of concrete surfaces and concrete sealing situations.
Silane/siloxane sealers are sealers that contain particles of silane and siloxane. Silane particles are small, designed to penetrate past the surface of the concrete substrate. It is important to note, however, that silane/siloxane sealers are not concrete densifiers, and they will not react chemically with the material. Rather, the penetrating silane particles will work in concrete with the surface level siloxane particles to create a hydrophobic barrier that will comprehensively block out water and salts from passing through the concrete.
