Abstract
Coating compositions can be applied to substrates to produce a smooth finish by the use of a coating applicator having a mat of sized glass fibers and/or strands having fibers and/or strands projecting from the surface of the mat. The coating applicator has a core with two surfaces, a mat of sized glass fibers with projecting fibers and/or strands attached to one surface of the core. The glass fibers within the strands have a residue of a sizing composition having a carrier, a film forming polymer, and compatible coupling agent. The glass fibers within the strand may be selected from bulked, texturized, hollow, hollow with etching and solid continuous and staple glass fibers and mixtures thereof. The thickness of the mat on the core to comprise the applicator is in the range of about 0.125 to about 2 inches (3 to 50 mm.).
