SD433
SD 433 is a permeable water-based asphalt emulsion modified with blended polymers and special additives. SD 433 is used as an air barrier vapor barrier and water resistive barrier in above-grade wall assemblies. This product is applied through co-spray, 1-part spray or roller application to attain a 40-mil dry film thickness membrane. SD 433 can be applied over masonry, concrete, exterior gypsum sheathing, plywood, OSB and many other common building materials. This product fully adheres to the substrate and is rubber-like flexible.
