5. INSTALLATION INSTRUCTIONS
Mesh Application (Flashing)
Flashing with TEC
®
Skill Set™ Waterproofing Mesh for common
problem areas like; inside corners, outside corners, anywhere
vertical surfaces meet horizontal surfaces; or anywhere dissimilar
materials meet is optional.
To accomplish flashing, first pre-coat the substrate intersections 4"
on each side. Then fully embed the 6" wide waterproofing mesh in
both directions into the pre-coated areas with a 3" overlap on each
side. Allow to dry (approximately 30 to 45 minutes) before full
application of membrane.
Membrane Application
Clean substrate from dust with a damp sponge and install
membrane right away. For crack isolation apply one coat 50 mils
thick. For waterproofing installations, membrane must be applied in
two 25 mils thick coats over the entire surface. Using a 1/4”-1/2” nap
roller or 3/16” x 5/32” V-notch trowel, apply a continuous, even film
with overlapping strokes. Make sure there are no voids, bubbles or
breaks in the membrane after cured. Apply first coat at 25 mils wet
thickness measuring periodically with a wet film thickness gage. Let
it dry for 1 hour. Apply a second 25 mils thick coat at right angle to
the first in order to fill the imperfections and pinholes. If trowel used,
smooth out the membrane ridges with a flat side of the trowel
immediately after the application.
