Specification

Co. for detail recommendations.
All outside corners must be double-covered
to a minimum of 6" (152 mm) on each side of
the axis of the corners. Apply a 12" (305 mm)
wide strip of membrane; then cover it with a
full width sheet or overlap the full width a min-
imum of 6" (152 mm) from the axis on both sides
of the corner.
Cant strips of epoxy mortar, latex modified
cement mortar or urethane sealants should be
used on inside horizontal corners. Do not use
JS160H Mastic as a fillet. Ensure outside corners
are as smooth as possible and free of sharp
protrusions by rounding or chamfering.
Apply JS160H Mastic to all terminations and
overlaps within 12" (305 mm) of corners. For
inside corners at all vertical-to-horizontal transi-
tions, apply a troweled bead of JS160H Mastic
to the overlap. Trowel the mastic 3" (76 mm) up
and 3" (76 mm) out from the transition on the
seam. A 60 mil
(1.5 mm) maximum wet film
thickness is recommended. Apply mastic the
same day of application.
Protrusions and Drains
Areas around pipe, conduit or any protrusions
through the membrane should be taped with a
6" (152 mm) piece of Jiffy Seal 500. Jiffy Seal
500 should be forced and formed to fit tightly
to the protrusion and the deck.
At the drain opening, apply a light coat of
primer and allow it to fully cure. Cover the drain
at least 6" (152 mm) past all perimeters with Jiffy
Seal 500. Remove the release film, make an X
cut and form the Jiffy Seal 500 into the drain,
ensuring that the membrane has 100% contact
with the primed metal drain surface.
Double-ply the opening with a full sheet of
Jiffy Seal 140/60 over the Jiffy Seal 500. Cut
and form it around or into the protrusion or
drain. This should be followed with a troweled
bead of JS160H Mastic. Special care should
be taken in placing a troweled bead of
JS160H Mastic at any drain, conduit or protru-
sion where cutting or forming of the mem-
brane is required.
JS160H Mastic and Protecto Wrap primers
are specifically formulated for use with Jiffy
Seal membranes. Substitutions are specifically
not recommended.
A good drainage design at or near the
footings, along with a drainage mat, will assist
in having a waterproof system. Protecto Wrap
2000V and 2000H drainage boards are rec-
ommended and approved for use with the
Jiffy Seal waterproofing system.
Expansion Joints and Cracks
For joints less than 1/4" wide (6.4 mm) with move-
ment less than 25%, use a 12" (305 mm) strip of
Jiffy Seal 140/60 to cover the opening.
All joints 1/4" (6.4 mm) and wider, or those
that move 25%
or more, must be treated as a
standard expansion joint. Follow the
approved sealant manufacturer’s recom-
mendation for design and use of appropriate
sealing materials.
Place a 12" (305 mm) strip of Jiffy Seal 140/60
face down over the expansion area, leaving
the release film in place to create a slip plane
over the joint. Cover the entire deck with stan-
dard width Jiffy Seal 140/60. Apply the material
from the low point of the slope to the high
point in a shingling effect. Remove the release
film and place protection board immediately
after application of the membrane.
APPLICATION
Priming
The application surface must be cleaned
using a broom, vacuum or an air compressor
dispensing clean, dry air so that all dust, loose
concrete, etc., is removed.
Thinning of the primer is not recommended.
When not in use, seal open containers to pre-
vent evaporation of the solvents.
Apply primer to all surfaces by roller or brush,
at a rate of 150 - 250 ft
2
/gal (3.8 - 6.3 m
2
/L),
depending on the porosity of the surface.
Primed surface must be free of runs, puddles or
excessive primer, as the presence of these con-
ditions can result in blistering.
The entire surface to be waterproofed
must be primed. Brush or roll out all primer
puddles or drips immediately. Prime only as
much of the surface as can be covered with
the membrane in half a working day. Do not
cover wet primer. The primed surface must be
protected from dust. Apply membrane when
primer is tacky but not wet.
Test the primer using the “Rule of Thumb”
method. Press thumb firmly on the primed sur-
face and twist. If the primer feels pliable but
does not adhere to thumb, the primed sur-
face is ready for membrane application.
Primed areas not covered within 8 hours
must be reprimed. If an area must be reprimed,
do not remove existing primer, but be certain
the area is clean and dry. The surface must be
free of dust, dirt and moisture. Reprime and
again allow the primed area to become tacky
prior to applying the membrane.
For all vertical applications over 8' (2.4 m) in
height, a second coat of primer should be
applied to the top 10" (254 mm) of the surface
to be covered. The membrane can be
applied when the second coat of primer is
tacky but not wet. The top 10" (254 mm) of the
membrane, along with all overlaps, must be
firmly rolled.
Vertical Application
After application of No. 100 Primer, run a strip of
Jiffy Seal 500 along the footing joint. Jiffy Seal
500 is unreinforced and may be formed well
into the footing corner reaching 3" - 6" (76 - 152
mm) up the vertical wall and 3" - 6" (76 - 152
mm) onto the footing, conforming to any irreg-
ularities in the surface.
Remove the release film from Jiffy Seal 500
and apply Jiffy Seal 140/60 from the top edge
of the wall downward so that the tack side
faces the primed surface. Pull the Jiffy Seal off
of the roll to the desired height on the wall or to
the height that is going to be readily backfilled.
Set the top edge of the sheet firmly onto
the primed surface. Roll or squeegee down-
ward in the center of the material working
outward to the edges.
Jiffy Seal must be rolled or squeegeed over
the entire membrane surface to gain maximum
surface contact to the primed wall. The top 10"
(254 mm) edge of the membrane and all over-
laps of the membrane must be well-adhered.
Bring Jiffy Seal 140/60 down the wall and
onto the footing. Terminate the membrane a
minimum of 3" (76 mm) over and past the edge
of the footing.
As application proceeds, remove the Zip
Strip from the preceding sheet of Jiffy Seal.
Move the roll over and align the overlap.
Again, pull the membrane off the roll to the
desired height and depress the top edge of
the material into the primer. Roll or squeegee
downward in the center of the material.
Working outward to the edges and pay par-
ticular attention to the overlap area. Remove
the release film from the entire membrane
the same day of application and install pro-
tection system.
Mastic Application
Ensure the release film is removed prior to
application of JS160H Mastic. Apply a trow-
eled bead of JS160H Mastic at the top edge
of the applied membrane and extend cover-
age at least 1" (25.4 mm) onto the wall and 1"
(25.4 mm) onto the membrane. JS160H Mastic
also must be applied at any other termination
of the membrane, and this application must
take place at the end of the working day or
