APPLICATION

1. Stir thoroughly until all settled pigments are dispersed and the adhesive is uniform in color.

Minimum 5 minutes stirring is recommended.

2. The surface, on or against which adhesive is to be applied, shall be clean, smooth, dry, free of fins,

sharp edges, loose and foreign materials, oil and grease. Depressions greater than ¼” (6 mm)
should be feathered, using epoxy, mortar or other approved patching material. All sharp
projections shall be removed by sweeping, blowing or vacuum cleaning.

3. After thorough stirring (minimum 5 minutes), apply Flex TPO Bonding Adhesive to substrate and

membrane using a 9” (23 mm) medium nap roller. Application shall be continuous and uniform
avoiding globs or puddles. An open time of 5 to 50 minutes, based on drying conditions are
recommended before assembly. Flex TPO Bonding Adhesive must be allowed to dry until it does
not string or stick to dry finger touch. Any coated area which has been exposed to rain should be
allowed to dry and then recoated. Do not apply adhesive to splice areas to be hot air welded.

4. Roll the membrane onto the adhesive coated substrate while avoiding wrinkles. Immediately

brush down the bonded portion of the sheet with a soft bristle push broom or a clean dry roller
applicator to achieve maximum contact.

Flex TPO Bonding Adhesive- 60 ft² (5.6m²) per gallon finished surface. Coverage rates are average and
may vary due to conditions on the job site. Porous surfaces and substrates may require more bonding
adhesive than the typical coverage rate.

CAUTIONS

1. Review the applicable Material Safety Data Sheet for complete safety information prior to use.

2. Flex TPO Bonding Adhesive is EXTREMELY FLAMMABLE- It contains solvents that are
dangerous fire and explosion hazards when exposed to heat, flame or sparks. Do not smoke while
applying. Do not use in a confined or unventilated area. Vapors are heavier than air and may
travel along ground or may be moved by ventilation and ignited by pilot lights, other flames,
sparks, heaters, smoking, electrical motors, static discharge, or other ignition sources at locations
distant from material handling point and flashback. All containers should be grounded when
material is transferred from one container to another. A red caution label is required when
shipping. A fire extinguisher should be available. In case of fire, use water spray, foam, dry
chemical or carbon dioxide. Do not use a solid stream of water because it can scatter and spread
the fire.

3. Avoid breathing vapors. Keep container closed when not in use. Use with adequate ventilation.
If inhaled, remove to fresh air. If not breathing, perform artificial respiration. If breathing is
difficult, give oxygen. Call a physician immediately. During application, efforts must be made to
prevent fumes from entering the building via air ventilation ducts. Do not place open containers
or mix adhesive near fresh air intake units. When possible, shut down or seal off the closest units.

4. If swallowed, DO NOT INDUCE VOMITING. Call a physician immediately.

5. Avoid contact with eyes. Safety glasses or goggles are recommended. If splashed in eyes, flush
eyes with plenty of clean water for at least 15 minutes. Contact a physician immediately.

6. Avoid contact with skin. Wash hands thoroughly after handling. In case of contact with skin,
thoroughly wash affected area with soap and water. Contact physician if irritation persists.

Note: Solvent resistant gloves are recommended to be worn when using this product to protect
hands from irritating ingredients.

7. Do not thin Flex TPO Bonding Adhesive. Thinning will affect performance. Excessively thick or
gelled material should be discarded.

8. Job site storage in excess of 90ºF (32ºC) may affect product shelf life. Should the Flex TPO
Bonding Adhesive be stored at temperatures lower than 60ºF (15ºC), restore to room temperature
prior to use.
