Abstract
Skid-resistant moisture barriers of the invention, such as house wrapping, waterproofing membranes, and roofing underlayrnents, have a carrier sheet with polymer nodules deposited thereon through a rotating screen roll or by transfer means such as a gravure roll. Precise coating levels and polymer distribution can be achieved more easily when compared with prior art coating and embossing methods.
