Abstract
Abstract A textured building material, suited for use as an acoustical wall and ceiling covering, comprising a cellular urethane foam substrate and an elastomeric coating and a method for its production is disclosed. The building material is flexible and damage resistant, which makes it especially useful in mobile vehicles and homes. The process consists of applying a foamed elastomeric resin emulsion onto a urethane substrate to a desired thickness; drying the coated substrate thus formed; and thereafter crushing the dried elastomeric coated substrate to form a composite textured material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
65 words
A composite building material having a continuously textured surface comprising: (a) a resilient urethane foam substrate, said substrate having an irregular sea sponge cell structure; and (b) a cured elastomeric layer adjacent to and embedded in the cells of one surface of said substrate, said elastomeric layer having an exposed surface with a texture which approximates the cellular structure of the adjacent sea-sponge substrate surface.
Claim 2
Dependent Claim
65 words
A composite building material having a continuously textured surface comprising: (a) a resilient urethane foam substrate, said substrate having an irregular sea sponge cell structure; and (b) a cured elastomeric layer adjacent to and embedded in the cells of one surface of said substrate, said elastomeric layer having an exposed surface with a texture which approximates the cellular structure of the adjacent sea-sponge substrate surface.
