R-Guard - Spray Wrap Rain Screen 1 Gal - Prosoco

Spray Wrap Rain Screen is a fluid-applied air and water-resistive barrier engineered for pressure-equalized rainscreen wall assemblies. This spray-applied formula dries into a durable, seamless, elastomeric membrane that protects exterior sheathing while allowing vapor transmission.

Fast installation reduces labor costs and eliminates risks associated with taping and lapping. The dark charcoal color conceals the backup wall behind open-jointed or vented cladding. Seamless application prevents tears, holes, and improper joints that compromise performance.

Minimizes air leaks that cause condensation buildup and energy loss. Vapor-permeable design allows trapped moisture to escape, reducing mold and mildew risk while protecting structural integrity. Low-odor, non-toxic formulation.

Compatible with most paints, sealants, and self-adhered waterproofing. Suitable for vertical, above-grade applications on gypsum, plywood, OSB, CMU, cast concrete, and other standard building substrates. Works effectively with cavity wall, masonry veneer, stucco, and EIFS assemblies.
