Membrane Installation
Apply Grace Vycor V40 in fair weather when the air, surface and
membrane are at temperatures of 25°F (-4°C) or higher. After
precipitation, allow a minimum of 24 hours for drying before
installing the ashing.
Cut the membrane to appropriate length. Peel back the release
liner, align the membrane, press into place and rmly roll. Laps
must be a minimum of 3 in. (75 mm). Mechanically fasten
the membrane at vertical terminations. Consistent with good
construction practices, install Grace Vycor V40 such that all laps
shed water. The top membrane layer should go over the bottom
layer. Always work from the low point to the high point.
