gENERAL APPLICATIONS
Fill small pitch pockets:
1. Depending on the depth of the
pocket, use two or more coats or
passes of the foam to obtain the
desired thickness (Figure 2). Apply
the foam in layers of 2" (5 cm) or
less in any single pass.
Note: If the foaming area to be filled is
wide, start by spraying from the edge
and build toward the center.
2. In approximately 5 minutes, the foam
should be no higher than the top of
the pocket.
Repair parapet/roof:
1. If the area to be repaired has been
previously painted, scrape away
all loose or poorly adhered paint.
Conduct an adhesion test if any
previously painted surfaces are
involved in the repair.
2. If the area is wet, let the surface
dry completely. Any additional
moisture may cause premature
curing and limit work time of the
FROTH-PAK ™ Foam Sealant.
3. Check the underlying substrate for
soundness and repair, if applicable.
4. Cut the damaged or blistered area
at an inward, tapered, 45° angle
(Figure 3). Cut back any defective
and moist foam until solid, dry
foam is exposed. Where possible,
remove at least 6" (15 cm) beyond
the area to be repaired.
5. Place a piece of plywood wrapped
in polyethylene next to the area to
be filled.
6. Depending on the depth of the
repair area, use two or more coats/
passes of FROTH-PAK ™ Foam
Sealant to obtain a thickness that
is approximately 2" (5 cm) from the
top of the area. Apply the foam in
layers of 2" or less in any single
pass (Figure 4).
7. To “form” the final pass, place the
plywood wrapped in polyethylene
over the area to be filled. Carefully
spray the foam under the plywood,
holding the plywood down (Figure 5).
Wait about a minute for the foam
to rise to the underside of the
plywood and begin curing. Remove
the plywood, checking that the
foam is equal to the height of the
surrounding parapet.
8. In approximately 5 minutes, remove
any overspray with a roofing knife
(Figure 6). If additional shaping is
required, cut the cured foam with a
handsaw.
APPLy FINISh COATINg
(IF REquIREd)
Brush or roll a 30-40 mil quality
protective coating (similar to the
originally applied coating) within 3
hours after application.
dISPOSAL
