OPCMIA General President Daniel E. Stepano released a memorandum.

National Gypsum Company is the exclusive service provider of reliable, high-performance products manufactured by its affiliate companies and marketed under the Gold Bond®, PermaBASE®, and ProForm® brands.

Stucco is a very versatile material that can be applied to just about any structure, with just about any sheathing, and can accommodate flat or curved surfaces either externally or internally.

In the past, when French lace textures or heavy grit sand finishes were popular, preparing the brown coat was a matter of rodding a wall, knocking off the clinkers and curing the heck out of the plaster.

Imagine not just applying plaster as a protective and decorative finish but as the primary material for the walls themselves.

The 2021 IBC has now been published, and with it came some significant changes/improvements for stucco assemblies over wood-based sheathing.
