National Gypsum is the manufacturer of PermaBase® cement board, which is often used as a substrate for exterior wall systems intended for stucco application. PermaBase’s reinforced edge allows for closer fastener application of nails or screws at the ends without crumbling or spinout. It’s highly durable being both moisture and impact resistant. PermaBase helps applicators to speed up their schedules by being faster, easier and cleaner than the traditional metal lath and scratch coat method.
National Gypsum also has an excellent lineup of veneer finish plasters including Uni-Kal®, X-KALibur® and Kal-Kote®. Each plaster in the Gold Bond lineup has a high resistance to cracking, nail-popping, impact and abrasion failure. Each plaster is designed to offer rapid installation to reduce overall construction time. Because each of the plaster components are mill-mixed you can expect uniform installation performance and outstanding job quality regardless of your batch size. Uni-Kal® and X-KALibur® plasters are both single coat systems that need to be applied over specific substrates, while Kal-Kote® is a two-coat system that bonds directly to Kal-Kote Basecoat.
Plaster additives, both an accelerator and retarder are also available from the National Gypsum stable of products.
