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.
