SPRAY-APPLIED AIR & WATER-RESISTIVE BARRIER FOR RAIN SCREEN SYSTEMS
Spray Wrap Rain Screen is a high-performance, fluid-applied air and water barrier that creates a seamless, durable, elastomeric membrane on exterior sheathing. Designed specifically for open-jointed and vented rain screen cladding systems, this advanced formulation protects against air and moisture infiltration in above-grade wall assemblies.
FEATURES
-
Gray finish – visually hides the backup wall behind open joints or vented cladding
-
Fast spray application – lowers labor costs and speeds up installation
-
Airtight performance – minimizes energy loss and prevents condensation
-
Durable protection – shields sheathing from water damage
-
Seamless membrane – no risk of holes, tears, or faulty lap joints
-
Low-odor and non-toxic – safe and easy to apply on-site

OVERVIEW
Spray Wrap Rain Screen is purpose-built for pressure-equalized rain screen assemblies, offering best-in-class weatherproofing performance. It dries into a resilient, vapor-permeable rubberized membrane that stops air and water leakage while allowing trapped moisture to dry. Ideal for cavity walls, masonry veneers, EIFS, stucco, and a variety of cladding systems, Spray Wrap Rain Screen helps prevent mold, mildew, and energy loss—while maintaining compatibility with most paints, sealants, and waterproofing products. Trusted for vertical, above-grade wall protection across a wide range of substrates, including gypsum, OSB, plywood, CMU, cast concrete, and more.
