All data are averages of several tests under laboratory conditions. In practice climatic variations such as temperature, humidity, and porosity of substrate may affect these values.
• Only proceed with application when ambient temperature is minimum of 50°F (10°C) and falling, and more than 6°F (3°C) above dew point. Temperatures must be maintained within this range for at least 24 hours after the installation. Do NOT proceed with application when the temperatures drop below 50°F (10°C), if precipitation is expected, or if humidity is at or above 80%. Coating should not become wet within 48 hours after application. Special precautions are to be taken when ambient and/or substrate temperatures are approaching, at, or above 90°F (32°C) and it may be necessary to limit material application to evening hours. • Hot surfaces should be cooled and shaded while cold surfaces should be heated and sheltered. Mixing: • Condition material to 70°F to 80°F (21°C to 27°C) prior to mixing and application. • Use chemical resistant (Nitrile) gloves and goggles when mixing or applying RE-ROOF White Urethane Top Coat. • Open container and mix at slow speeds (not exceeding 500 rpm) for 1–2 minutes to evenly distribute pigments and other ingredients that may have settled, until a homogeneous mixture is achieved. Thoroughly scrape sides of pail as material is mixed. Boxing material is recommended to ensure color uniformity. Page 1 of 3

RE-ROOF White Urethane Top Coat • Use caution not to whip air into the material as this may result in pinhole blisters and/or shortened pot life. Do not mix in an up and down motion. Application: Read all instructions thoroughly prior to installation. • Flashing Treatment: Treat edges, seams, joints, metal flashing, penetrations and transitions with a RE-ROOF urethane flashing. Refer to the corresponding RE-ROOF urethane flashing Technical Data Sheet for surface preparation, mixing and application instructions, dry mil thickness requirements, approx. coverage, curing and recoat times. Allow to cure and pay close attention to recoat times. • Primer: Apply the appropriate primer to the field areas in preparation for a RE-ROOF urethane base coat. Refer to the corresponding primer Technical Data Sheet for surface preparation, mixing and application instructions, approx. coverage, curing and recoat times. Overlap the flashing according to the primer instructions. Allow to cure and pay close attention to recoat • First Base Coat: Apply the first coat of a RE-ROOF urethane base coat. Refer to the corresponding RE-ROOF urethane base coat Technical Data Sheet for surface preparation, mixing and application instructions, dry mil thickness requirements, approx. coverage, curing and recoat times. Allow to cure and pay close attention to recoat times. • Second Base Coat: Apply the second coat of a RE-ROOF urethane base coat. Allow to cure and pay close attention to recoat times. Inspect the surface for damage prior to the application of RE-ROOF White Urethane Top Coat. Any surface damage must be repaired with a REROOF urethane base coat prior to the application of RE-ROOF White Urethane Top Coat. • First Top Coat: Apply the first coat of RE-ROOF White Urethane Top Coat in a monolithic application at a rate of 94 ft²/gallon to achieve a minimum of 17 (± 1) mils WFT (wet film thickness). Use an airless sprayer, brush, or phenolic resin core roller. RE-ROOF White Urethane Top Coat must be a uniformly thick, void-free, continuous membrane across the entire roof surface. Allow to cure and pay close attention to recoat times. Notes: Do not apply RE-ROOF White Urethane Top Coat at a rate of more than 1 gallon per 100 ft². Sagging and running is more likely to occur on sloped, slanted and vertical areas especially when the coating is applied to thick. Thicker coating applications also increase the chances of bubbles, blisters and/or pinholes. If necessary, apply RE-ROOF White Urethane Top Coat in several thinner coats, allowing each coat to properly cure. • Second Top Coat: Apply the second coat of RE-ROOF White Urethane Top Coat in a monolithic application at a rate of 94 ft²/gallon to achieve a minimum of 17 (± 1) mils WFT (wet film thickness). REROOF White Urethane Top Coat must be a uniformly thick, void-free, continuous membrane across the entire roof surface. Notes: Always verify that the proper WFT (wet film thickness) has been achieved by measuring each coat using a wet film gauge. As a minimum, it is recommended to check the mil thickness in every corner, plus the center areas of the roof. Large areas will require many check points. When applying multiple, thinner coats, verify that the total DFT (dry film thickness) meets the stated requirements. See coverage chart for minimum WFT (wet film thickness) mil guidelines and DFT (dry film thickness) mil requirements. Total System Thickness (field areas): 54 mils DFT Notes: Total system thickness requirement excludes additional dry mils of primer coat(s), and flashing. Curing: • Curing time for RE-ROOF White Urethane Top Coat is typically 16 hours
at 75°F (24°C) and 50% relative humidity. Notes: Mix White Urethane Top Coat with RE-ROOF Urethane Accelerator when faster curing times are desired. Refer to RE-ROOF Urethane Accelerator Technical Data Sheet for more information. When RE-ROOF White Urethane Top Coat is mixed with RE-ROOF Urethane Accelerator, curing time is approx. 8 hours [based on 75°F (24°C) and 50% relative humidity]. • Apply second coat of RE-ROOF White Urethane Top Coat within a maximum of 48 hours after the first coat of RE-ROOF White Urethane Top Coat. Note: When RE-ROOF White Urethane Top Coat is mixed with RE-ROOF Urethane Accelerator, apply the second top coat within a maximum of 24 hours. • If more than 48 hours has passed after the first application of RE-ROOF White Urethane Top Coat [24 hours if RE-ROOF Accelerator is used], re-prime with RE-ROOF Primer PO before proceeding with the second application of RE-ROOF White Urethane Top Coat. • Allow to cure for at least 48 hours [based on 75°F (24°C) and 50% relative humidity] before permitting light pedestrian traffic on the finished surface. Limitations: • Do not dilute under any circumstance. • High temperatures and high humidity will accelerate the cure time. Low temperatures and low humidity will extend the cure time. Clean-up: Clean tools and equipment with Methyl Ethyl Ketone (MEK), Xylene, or similar product immediately after use. Cured material must be removed mechanically. Packaging: RE-ROOF White Urethane Top Coat is packaged in a 5-gallon pail (18.9 liters). Shelf Life & Storage: • 12 months in unopened, original packaging when stored at temperatures between 40°F and 80°F (4.4°C to 27°C). • Keep containers closed, store in a dry, cool place away from heat, direct sun, sparks, open flame, and moisture. • Protect material from freezing.
