5. Installation
STORAGE & HANDLING
Store all materials in a dry space at tempera-
tures between 50 and 90 degrees F (10 and 32
degrees C). Do not store in direct sunlight. Do
not remove from box until ready to use.
PREPARATORY WORK
Deliver materials in manufacturer’s original,
unopened, undamaged containers with identi-
fication labels intact. Store materials protected
from exposure to harmful environmental
conditions and at temperature and humidity
conditions recommended by the manufacturer.
Verify that site conditions are acceptable
for installation. Do not proceed with installation
until unacceptable conditions are corrected.
Surfaces should be clean, dry, free of dirt
and other foreign matter. There should be no
solvent based caulks used in conjunction with
BT25XL. This product eliminates the need for
caulk.
For best results, apply BT25XL at a tempera-
ture above 45 degrees F (7 degrees C). For
applications from 20 - 45 degrees F (-7 - 7
degrees C), the material must be stored in a
warm area prior to use and must be applied
with either Protecto Wrap BT-Primer or
Protecto-Tak Spray Adhesive.
When used as an air/vapor barrier system,
all lap and butt joints must overlap a minimum
of 4" (102 mm). Masonry ties must be placed
on top of the BT25XL and sealed with Protecto
Wrap’s JS160H Mastic.
BT-Primer Application
Apply primer to all surfaces by roller or brush. The
primed surface must be free of runs, puddles or
excessive primer, as this can cause blistering.
Brush or roll out all primer puddles or drips
immediately. Prime only as much area as can
be covered in half a day’s work. Reprime
areas not covered in half a day’s work with a
light coat of BT-Primer.
The primer will become tack free in approx-
imately 10 - 20 minutes. When not in use, con-
tainers must be tightly sealed to minimize
evaporation of the solvents.
Note - Some surface bubbling in the primer
may occur as it cures. This will not affect per-
formance of the product. Bubbles will smooth
out as the membrane is applied.
