ABSTRACT:
This invention concerns coating and impregnating compositions for concrete of an essentially anhydrous character comprising (1) a monomer blend of (a) dicyclopentenyl or dicyclopentenyloxyalkyl methacrylate or acrylate and (b) hydroxy alkyl methacrylate and (2) a polymerization catalyst of (a) an organic peroxide and an aromatic amine accelerator, or (b) a polyvalent metal salt or complex and an organic hydroperoxide, or (c) mixtures of (a) and 0.0005% to 2% by weight, based on total amount of monomers, of a polyvalent metal salt or complex, or (d) mixtures of (a) and (b), which can be applied to porous surfaces such as concrete as an impregnant and which can be polymerized in situ in order to reduce the permeability of the surface and to provide hard, continuous, hydrophobic, wear resistant and weather resistant surfaces.
