Sure Cavity® Rainscreen Drainage Plane Installation
Sure Cavity® Rainscreen Drainage Plane Installation
Follow these steps for the correct installation of Sure Cavity® rainscreen drainage plane/drainage mat:
Installation Steps:
- Roll out the Sure Cavity® rainscreen drainage plane/drainage mat over the WRB (weather-resistant barrier) on the backup wall, with the spunbond fabric facing the installer.
- Back-wrap 4 inches of fabric on the bottom course to act as a bug screen.
- Fasten the rainscreen mat using a hammer stapler for wood backup walls or apply dabs of adhesive on masonry surfaces. Only install as much as can be covered with lath or siding on the same day to prevent wind damage.
- For subsequent courses, roll out the next section of Sure Cavity® rainscreen drainage mat. Overlap the fabric only—plastic should butt directly against the top of the course beneath it.
- Install the veneer material, which will sandwich the Sure Cavity® rainscreen drainage mat in place in thin veneer applications.
