Spray adhesives are commonly used to attach various building materials, such as drain boards, insulation boards, and protection boards, to waterproofing systems, building envelope membranes, and sealants. Determining chemical compatibility and ensuring strong adhesive bonds is essential. Several spray adhesives have been tested and approved for use with W. R. MEADOWS products, as shown in the table below.

Please note: These spray adhesives are intended only for use where specifically indicated and are not intended to replace or supersede MEL-PRIME or like primers/adhesives when installing the initial W. R. MEADOWS product. See specific W. R. MEADOWS technical data sheet for full installation information.

These recommendations are provided to help licensed design professionals and installers understand product compatibility. They are not intended to replace project specifications and should not be used as a standalone reference. All W. R. MEADOWS products must be installed in accordance with the applicable drawings, details, and product literature. This document does not extend any additional approvals or extend the use of products beyond the terms of W. R. MEADOWS published warranties.
