JSIWGHT-BUTYL rev 7/12
SHELF LIFE
Jiffy Seal BUTYL Ice & Water Guard HT maintains optimum initial adhesion to substrates when used
within one year from the date of manufacture.
STORAGE
Jiffy Seal BUTYL Ice & Water Guard HT should be stored in the original, unopened container at
ambient temperatures between 40°F to 90°F (5°C to 32°C). Storage area should remain dry and out of
direct sunlight. Do not remove materials from original containers until ready for use. Do not double stack
pallets. Do not store rolls on end.
PREPARATION
Roof deck surface shall be clean, dry and free of any foreign materials. The roof deck surface shall be
free of gaps, sharp edges and protrusions. Do not walk on surface when wet or covered with frost as
there is an increase risk of injury.
Metal surfaces may need to be solvent wiped and/or abraded to achieve optimum adhesion.
On vertical applications, all surfaces shall be clean, dry and free of any foreign materials. The surface
shall be free of gaps, sharp edges and protrusions.
Priming
Prime DensGlass Gold, DensDeck, masonry and concrete substrates: for other substrates such as wood
composition and gypsum sheathing, prime as necessary if adhesion is found to be marginal. Refer to:
“Technical Letter Primer Recommendations” for more information regarding primer recommendations and
“Technical Lettter Adhesion to Substrates” for adhesion guidelines.
APPLICATION
Jiffy Seal BUTYL Ice & Water Guard HT can be installed on any exterior grade solid sheathing normally
used for roof decking. Apply Jiffy Seal Ice & Water Guard HT only in fair weather conditions when air,
roof deck and membrane temperatures are at 40°F (5°C) or higher.
Install membrane such that all laps shed water in both vertical and horizontal installations.
Valleys require a minimum 18” wide roll of Jiffy Seal BUTYL Ice & Water Guard HT centered down the
full length of the valley.
Install membrane starting at the lowest point of roof slope and work up the slope.
Position the roll into the desired location, roll out the membrane and cut to length as needed.
Align the roll with edge of eave or overlap of preceding roll, pull membrane tight, start by removing a
portion of the release liner and adhere to roof deck (reposition as needed prior to removing the remaining
release liner).
Lift the opposing end of the membrane and remove or strip the release liner, pulling it to one side, keep
membrane aligned and tight, adhere membrane to the roof deck while another person brooms the sheet
flat.
Edge laps are 3” minimum and end laps are 6” minimum. All laps should be firmly pressed or rolled to
ensure a positive seal.
VERTICAL APPLICATION
Apply first piece to the rough opening sill; firmly roll into place using a hand roller (J-roller, Laminate roller)
to smooth out any wrinkles, air bubbles or creases that would allow water to migrate behind the
membrane. Set window into the rough opening and fasten per window manufacturer’s instructions. Apply
vertical pieces over the nailing flange at the sides of window frame, firmly roll into place using a hand
roller to smooth out any wrinkles, air bubbles or creases, apply the final piece over the top nail flange and
overlap the vertical side pieces, firmly roll into place using a hand roller to smooth out any wrinkles, air
bubbles or creases.
Through-wall flashing and full wall air/vapor barrier applications should be installed to shed water to the
exterior of the building.

CLEAN UP
Dispose of waste in accordance to local requirements. Control worksite so that boxes and release liner do
not present a hazard.
