R-Guard Spray Wrap MVP Air & Water-Resistive Barrier - Bulk

R-Guard Spray Wrap MVP — Fluid-Applied Air & Water-Resistive Barrier for Above-Grade Wall Assemblies PROSOCO R-Guard® Spray Wrap MVP is a fluid-applied air and water-resistive barrier engineered to stop air and water leakage in cavity wall, masonry veneer, stucco, EIFS, and most other building wall assemblies. Applied as a liquid, it dries quickly into a rubberized, highly durable, water-resistant, vapor-permeable membrane that conforms and adheres to most common building surfaces. Designed for contractors working on above-grade wall systems, Spray Wrap MVP delivers superior protection against water intrusion while minimizing condensation risk within wall cavities. It is intended to be used as the primary air barrier over above-grade wall assemblies prepared with R-Guard Joint & Seam Filler and/or R-Guard FastFlash. The latest formulation of Spray Wrap MVP features improved viscosity for better sprayability, making application faster and more consistent across large wall areas. Unlike mechanically attached wraps, this fluid-applied system conforms to irregular substrates and integrates seamlessly with most paints, sealants, and self-adhered waterproofing or air barrier components, reducing compatibility concerns on complex assemblies. Key Features & Benefits Improved Viscosity for Better Sprayability The updated Spray Wrap MVP formula features improved viscosity specifically engineered for more consistent spray application. This means contractors can achieve more uniform coverage with less effort, reducing application time on large-scale projects. Rubberized, Vapor-Permeable Membrane Once cured, Spray Wrap MVP forms a rubberized membrane that remains vapor-permeable, allowing walls to dry out while still blocking bulk water and air infiltration. This balance is critical in modern wall assemblies where trapping moisture can lead to long-term structural damage. Superior Air and Water Leakage Control Spray Wrap MVP is formulated to stop both air and water leakage across a wide range of above-grade wall assemblies. Controlling air infiltration reduces energy loss and protects the building envelope, a key concern for contractors building to modern energy codes. Broad Substrate and Assembly Compatibility The membrane adheres to most common building surfaces and is compatible with most paints, sealants, and self-adhered waterproofing or air barrier components. This broad compatibility simplifies coordination across trades and reduces the risk of product conflicts on the job site. Conforms to Irregular Surfaces As a fluid-applied product, Spray Wrap MVP conforms to the contours of the substrate, sealing around penetrations and irregular surfaces that would be difficult to wrap with sheet products. This results in a more continuous, monolithic barrier across the wall assembly. Living Building Challenge Red List Reviewed Spray Wrap MVP has been reviewed for conformance with the Living Building Challenge Red List, and PROSOCO has verified it does not contain intentionally added chemicals present on the Red List (affidavit available). The product also complies with LEED 2009 and LEEDv4 referenced architectural coating and sealant regulations including CARB 2007 SCM, SCAQMD Rule 1113, and SCAQMD Rule 1168, supporting green building project submittals. Common Applications Cavity Wall Construction Apply Spray Wrap MVP over cavity wall assemblies as the primary fluid-applied air and water-resistive barrier, protecting the wall cavity from air and moisture infiltration. Masonry Veneer Use on masonry veneer wall assemblies where a continuous, rubberized air and water barrier is required behind the veneer cladding system. Stucco Systems Spray Wrap MVP is suitable for use as the water-resistive barrier in stucco wall assemblies, providing a durable substrate barrier before stucco application. EIFS (Exterior Insulation and Finish Systems) Apply as the air and water-resistive barrier layer in EIFS assemblies to manage water and air movement behind the insulation and finish layers. Above-Grade Wall Assemblies with R-Guard System Components Use Spray Wrap MVP as the primary air barrier over above-grade wall assemblies prepared with R-Guard Joint & Seam Filler and/or R-Guard FastFlash, creating a fully integrated R-Guard building envelope system.
