environments such as under copper or zinc metal roofing.
PS200
HT
must be covered with a finished roof covering
within the specified exposure time of the product. Refer
to section on Features and Benefits for exposure times.
Application
Cut the PS200
HT
roll to suitable, manageable lengths
before installation.
Place a full width piece of the pre-cut PS200
HT
underlayment on the substrate, parallel to the eave
(low) edge of the roof.
Align PS200
HT
so that it is parallel with the edge of the eave
and extend over the eave and rake approximately 3/8".
Place the side lap on the up side of the roof, fold back
the sheet, and remove the exposed release film, taking
care not to displace the sheet.
Working from the center out, roll the sheet onto the
substrate, taking care to avoid wrinkles and ridges.
PS200
HT
must be set straight. Repeat this process for
the remaining half of the sheet.
Apply a 1/16" thick layer of asphalt plastic cement
over the eave and rake metal drip edges extending
2" to 3" onto the deck surface where the roll will
intersect.
Apply full roll width, a 1/16" thick layer of asphalt
plastic cement to the surface of the first course in the
6" end lap area before adhering the next course.
Surface Preparation
Surface must be clean, dry, and without voids that
may interfere with adhesion.
For re-roofing, all old roofing and other loose
materials must be removed prior to installation.

For best results, surface may be primed with an ASTM
D41 Primer prior to installation of PS200
HT
. When
primer is used, ensure the primer is fully dry prior to
application of PS200
HT
.
Apply the next eave course in the same manner
overlapping the first course at the end lap by 6".
Remove release film covering the selvage, if present,
prior to application of the next sheet.
Lap the succeeding course over the lap area just to the
fabric edge of the preceding course.
Apply succeeding courses in like manner, as in steps
above.
Stagger the end laps a minimum 3' from the preceding
course.
Install capped or tin tagged nails 6 inches on center
in the middle of the selvage edge (side lap) or fasten
according to applicable building codes.
At the T-joint (where an end lap and next overlapping
course intersect), apply a bead of roofing lap cement
before the overlapping course is laid.
Roll the entire membrane surface, paying special
attention to side laps, end laps and T-joints. Roller
weight shall be 70 lb. minimum for low slope (<2:12
pitch) and 28 lb. minimum for steep slope (>2:12
pitch).
