Installation Instructions

adhesive is curing. Repositioning of the membrane is possible
while the adhesive is still wet. After the adhesive begins to
set-up (approximately 20 to 35 minutes) apply pressure with a
push broom to ensure good contact. This application requires
a porous substrate, such as High Density Fiberboard, OSB or
plywood.
Contact Application Method: For vertical or horizontal
applications. Open and thoroughly stir the White Membrane
Water Based Bonding Adhesive. Using a large nap roller,
apply White Membrane Water Based Bonding Adhesive to
both the substrate and the membrane at a rate of 100 square
feet per gallon. Use care not to get the adhesive into the seam
area(s). The adhesive is white when applied, but will turn clear
when ready for bonding. When adhesive is dry (clear) on both
surfaces, carefully fluff air under the top half of the membrane
and roll the membrane into the glued substrate. Roll the middle
of the membrane first, followed by the ends. DO NOT let the
ends of the membrane roll ahead of the middle. Finally, apply
pressure to the installed membrane with a push broom to
ensure good contact. Fold back the remaining unglued portion
of membrane and repeat this process.
If installing more
than one roll,
always install
the membrane so
that the flow of
water goes over
and not against
the lapped edges.
Start at the low
side of roof if
seaming rolls.
Allow the next roll of membrane to over lap the previous roll
of membrane a minimum of three inches (3"). Again, fold the
membrane onto itself so that one-half of the under side of the
membrane is exposed. Apply White Membrane Water Based
Bonding Adhesive to the substrate and proceed as you did with
the first roll.
