5.6 Allowable Substrates:
5.6.1 LeakBarrier self -adhering direct -bond to deck:
➢ New untreated plywood (unprimed or primed with ASTM D41 primer);
➢ Existing plywood (unprimed or primed with ASTM D41 primer);
➢ New or existing OSB (unprimed or primed with ASTM D41 primer);
➢ Structural concrete (unprimed or primed with ASTM D41 primer).
Note: Tarco does not require priming of new or existing plywood or OSB sheathing. New or existing
plywood or OSB sheathing should be cleaned of all dirt and debris prior to application of LeakBarrier
membranes.
ASTM Organic Mineral Surface Tile Underlayment or LeakBarrier EasyMop SBS Direct -Bond to Deck:
ASTM D41 primed structural concrete.
Note: Refer to 5.6.4 for uplift limitations associated with direct -deck underlayment installations where the
overlying roof cover is foam -on tile roofing.
5.6.2 Bond to Mechanically Attached Base Sheet:
LeakBarrier self -adhered to:
➢ ASTM D226, Type I or II felt;
➢ ASTM D4869 felt;
➢ LeakBarrier EasyLay, LeakBarrier EasyLay UDL 15, LeakBarrier EasyLay UDL Basic or LeakBarrier
EasyLay UDL 50.
ASTM Organic Mineral Surface Tile Underlayment or LeakBarrier EasyMop SBS in hot asphalt to:
➢ ASTM D226, Type I or II felt;
➢ ASTM D4601, Type II base sheet.
For installations under mechanically attached prepared roof coverings, base layer shall be attached per
minimum codified requirements. For installations under foam -on tile systems, base layer shall be attached
per minimum requirements of FRSA/TRI April 2012 (04-12).
5.6.3 LeakBarrier Self -Adhering Bond to Other Substrate Types:
➢ ASTM D41 primed metal (flashing metal, valley metal, etc.)
5.6.4 Wind Resistance for Underlayment Systems in Foam -On Tile Applications: FRSA/TRI April 2b12 (04-12)
does not address wind uplift resistance of all underlayment systems beneath foam -on tile systems, where
the underlayment forms part of the load -path. The following wind uplift limitations apply to underlayment
systems that are not addressed in FRSA/TRI April 2012 (04-12) and are used in foam -on the applications.
Maximum Design Pressure is the result of testing for wind load resistance based on allowable wind loads,
and reflects the ultimate passing pressure divided by 2 (the 2 to 1 margin of safety per FBC 1504.9 has
already been applied). Refer to FBC 1609 for determination of design wind loads.

➢ At all T-joints, where an end -lap and the next overlapping course intersect, apply a bead of roofing laps
cement before the overlapping course is laid.
➢ Roll the entire surface with a weighted roller, paying particular attention to side laps, end laps and eave
/ rake areas to ensure a complete bond.

deck per 5.6.1 or over mechanically attached base sheet per 5.6.2) is allowable for use under mechanically
attached prepared roof systems. Limits of use are those associated with the top -layer material. This is not
a requirement, but is allowable if a multi -ply underlayment system is desired.
6.5 Tarco 15 and 30:
6.5.1 Tarco 15 and 30 shall be installed in compliance with the requirements for ASTM D226, Type I and II
underlayments, respectively, in FBC Sections 1507 for the type of prepared roof covering to be installed.

FBC Sections 1507 for the type of prepared roof covering to be installed.
6.7.2 Re -fasten any loose decking panels, and check for protruding nail heads. Sweep the substrate thoroughly
to remove any dust and debris prior to application.
6.7.3 Non -Tile Applications:
Place a full width section of EasyLay, parallel to the eave edge of the roof and unroll 2 to 3 feet with the lay
lines facing up, and position to the edge of the eave and rake. Install a few fasteners at the top, near the
rake, and roll out the sheet to a manageable length. Pull, straighten and align the sheet so that any
wrinkles are eliminated and the sheet is even with the eave edge. Fasten with 3/8" headed roofing nails or
1" capped (plastic or metal) nails, driven by hand or pneumatically, spaced 6" o.c. at all laps in the center
of the seam area, and two staggered rows fastened 12" o.c. in the field of the sheet. Install nails such that
the head of the nail is flush with the surface, without cutting into the surface. Fasten from the top to
avoid walking or kneeling on unsecured sheet. Continue to the end of the substrate and fasten down.
Align the next roll over the preceding sheet so as to form a minimum 4", water -shedding lap, and install
per instructions above. Apply subsequent sheets in the same manner, with minimum 4" water -shedding
laps and minimum 8" end -laps, which are staggered minimum 36" fro the preceding course.
For double layer applications, follow the instructions noted above, but using a minimum 19", water -
shedding side lap.
Allow for minimum 6" up the vertical transitions and minimum 6" over hips and ridges.
At valleys, first install a vertical length of EasyLay down the center of the valley, then start at the low point
and work to the high point, rolling the membrane from the center outward in each direction, ensuring no
wrinkles or tears. Covered with valley -metal or other valley lining material in accordance with NRCA
recommendations.
Apply a thin coat of asphalt plastic cement to waterproof areas where any cuts or tears have occurred.
Seams or joints that require adhesive or sealant can be treated with high quality plastic cement (asbestos
free).
