Technical Specifications
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.
Acceptable substrates for adhesion of LeakBarrier membranes can be found at the Tarco website.
For best results, surface may be primed with an ASTM D 41 Primer prior to installation of EasyBase.
When primer is used, ensure the primer is fully dry prior to application of EasyBase.
If EasyBase is left exposed for more than 30 days, the EasyBase surface must be primed prior to
installation of a self-adhesive membrane.

Application
Cut the EasyBase roll to suitable, manageable lengths before installation.
Position the pre-cut EasyBase beginning at the lowest corner of the roof where the eave (gutter edge)
and rake (rising edge) intersect.
Align EasyBase so that it is parallel with the edge of the eave and extend over the eave and rake
approximately 3/8".
Starting at the middle and extending to one end of EasyBase, drive securing nails in 18" centers in the
side lap area, 1½" from the edge. Do not drive the nails all the way in.
Backroll the unsecured portion of the roll up the middle where the first securing nail is driven.
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.
Carefully remove the release film the full width of the sheet and apply the EasyBase membrane firmly
into place as it is being applied, taking care to avoid wrinkling or creasing of the roll.
Remove the securing nails from the other half of EasyBase, backroll and apply in like manner.
On slopes greater than 2:12, drive nails flush in the selvage area 1½" from the edge on 18" centers, after
EasyBase has been applied and prior to the next overlapping course.
Apply the next eave course in the same manner overlapping the first course at the end lap by 6".
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.
Lap the succeeding course over the side lap for minimum 3".
Apply succeeding courses in like manner, as in steps above.
Stagger the end laps a minimum 3' from the preceding course.
At the T-joint (where an end lap and next overlapping course intersect), apply a bead of asphalt plastic
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).
EasyBase is warranted to be free from manufacturer’s defects.
