• Polyester fabric surface allows for better walkability and cooler surface temperatures.
• Specifically designed for the demands of metal and tile roofing systems, with high temperature stability of 260 °F, and polyester fabric surface for maximum walkability. Non-skid surface also helps prevent tile from sliding off the roof.
• Split-back release film peels off for easy installation and handling.
• 180 day exposure limitation allows for long term dry in.
• Adheres directly to concrete, plywood, wood composition board and gypsum sheathing decks.
• Self-sealing around nails preventing moisture penetration.
• Product available for multi climates.
• Functions as a vapor barrier for commercial roofing applications.
• Meets ASTM D1970.
• Miami Dade County Approval NOA No. 18-1105.05.
• ICC-ES ESR-2116.
• Florida Building Code FL 10450-R10.
• UL Prepared Roofing File No. 16744.

• Tarco LeakBarrier PS200HT High Temp Ice and Water Shield rolls must be stored indoors, in a dry location.
• Rolls must be stored on end only. Do not store in a leaning position.
• The rolls must be protected from the elements. Do not expose rolls to direct sunlight.
• Store rolls at room temperature. Prolonged exposure to elevated temperatures may reduce the adhesive characteristics of the membrane.
• General Precautions
• Install Tarco PS200HT High Temp Ice and Water Shield only when material interface temperatures (air, deck, material) are 40 °F and rising.
• Do not install when any form of moisture such as water, ice, snow, dew, rain, etc. is present.
• Ensure roof has positive drainage prior to installation.
• Proper ventilation is critical. When applying over the entire roof deck, the roofing system must provide sufficient ventilation, including both ridge and soffit venting.
• A full, irreversible adhesion is achieved when the underlayment goes through a complete heat cycle. Do not attempt to remove the underlayment immediately after adhesion to the substrate.
• Use of a hand-held "hot air gun" might help in enhancing adhesion during application of underlayment in cooler weather.
• (Applicable for the State of Florida only) - All tiles shall be staged (two tile perpendicular to slope, four tiles on top parallel to slope), not to exceed 6-high. When installing flat tiles and lugged tiles above 6:12 roof pitch, PS200^HT shall be installed behind a nominal 1" x 2" horizontal batten.
• Not recommended for extreme high temperature environments such as under copper or zinc metal roofing.
• Tarco PS200HT High Temp Ice and Water Shield 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.

• 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 D41 Primer prior to installation of PS200^HT. When primer is used, ensure the primer is fully dry prior to application of PS200^HT.
• 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.
• 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).
