Abstract
This invention relates to impregnant compositions for porous substrates prepared from dicyclopentenyl and dicyclopentenyloxy (C.sub.1 -C.sub.4)alkyl acrylates and methacrylates and which include at least about 4% by weight of the impregnant composition of a component selected from the drying oil fatty acids and mixtures thereof. Cementitious surfaces impregnated with and sealed using these compositions exhibit improved water and crack resistance.
Claims11
A nonaqueous composition for impregnating cementious substrates comprising at least one monomer selected from the group consisting of dicyclopentenyl- and dicyclopentenyloxy(C.sub.1 -C.sub.4)alkyl acrylates and methacrylates and at least about four percent by weight of the composition of a component selected from the drying oil fatty acids and mixtures thereof.
