The MasterProtect H 400, formerly the Enviroseal 40, manufactured by the BASF chemical company, is a clear, water-based silane sealer. Silane sealers are a type of penetrating sealer that features small particles of sealant that penetrate past the surface of the concrete to lock out water and salts.
The MasterProtect H 400 is a reputable silane on the market. The MasterProtect H 400 is an excellent source of protection for chlorides, freeze/thaw cycles, and other such potential threats. Because of this and other characteristics of its chemical formula, the MasterProtect H 400 is a preferred sealer for certain environments that need protection from high traffic, whether from machinery or from humans. The smallest available quantity is a 5 gallon bucket so it is typically used in commercial applications.
The MasterProtect H 400 is also a great choice for commercial projects because of its international appeal. As it is manufactured by BASF, you can be assured that it will perform up to the high standard required of that company. Similarly, it is marketed across the world, as facilitated by the resources of a company as large as BASF.
