Abstract
Abstract A paint roller for producing texture paint surfaces having a cylindrical core with a paint applying and texturing cover bonded to the outer surface of the cylindrical core. The paint applying and texturing cover is an open web of interengaged continuous crinkled coarse filaments of resilient material. The open loops of the open web carry the texture paint material, apply it to the surface being painted, and texture it in essentially a single motion. During application, the loop elements are actually immersed in the texture paint material and lift it into peaks, thereby producing deeper textures than has generally been possible in the past.
