Abstract

See full text

A method of surface sealing a porous fibrous substrate is provided. According to the method, a porous fibrous substrate possessing a moisture content and a surface with pores is provided. A sealant composition is applied to a surface of the porous fibrous substrate and permitted to penetrate the surface pores of the porous fibrous substrate and undergo cure while participating in a foaming reaction with the moisture content to establish a water-resistant polymeric foam sealant impregnated into the porous fibrous substrate. The water-resistant polymeric foam sealant contains a polyurethane and/or polyurea.
