Fully Adhered TPO Single Ply Membrane
Consult Material Safety Data Sheets and container labels for specific safety instructions prior to use.
Avoid breathing vapors of solvent, sealant and adhesives. Use with adequate ventilation. Avoid prolonged contact of solvents, sealants and adhesives with skin.
Do not use TPO roofing products near fire or flame.
Do not use open flames for drying of surfaces, sealants, or adhesives.
Do not use oil-based paint on TPO Coated Metal or membrane. Contact Manufacturer's
Technical Service Department for recommendations.
Do not allow muriatic acid (masonry cleaner) to come in direct contact with the TPO Membrane or accessory products.
PART 3· EXECUTION
When installing a Fully Adhered Reinforced TPO Membrane Roofing System in cooler weather, it is recommended that liquids such as solvents, sealants, etc. be stored at warmer temperatures (60°F or more but not exceeding 80°F) until just prior to use in order to facilitate the installation.
3.02 Substrate Conditions
The following general conditions apply to the substrate that will receive a Fully Adhered Membrane Roofing System for new construction:
The roof deck must be structurally sound and free of defects. Any defects must be corrected prior to installing the roofing system.
Preparation Of Existing Substrate
Surface of roof deck must be clean and dry. Do not begin roofing if there is ANY trace of moisture on the deck surface.
Keep surface of roof deck clean throughout roof application.
Vapor Retarder Installation (where specified)
Specific climatic and job conditions may require the use of a vapor retarder. It is the sole
responsibility of the design professional to determine the need for a vapor retarder, and its type and location in the roofing system. A vapor retarder may often act as an "air barrier" which may have a positive effect in reducing internal air pressure. Vapor retarders should be strongly considered for buildings subject to high internal air pressures such as airplane hangars and bulldings with many loading bays such as warehouse facilities.
Nailers shall be firmly anchored to the decks at a maximum 2'-0" o.c. and shall resist a pullout force of 200 Ibs./linear foot in any direction. Spacing and fastener embedment shall conform to Factory Mutual Loss Prevention Data Sheet 1-49.
Refer to the Fastener Guidelines section in this manual for the type of fastener to be used with each type of deck and the maximum spacing requirements.
