RE-ROOF Acrylic Base Coat • Do not weld, smoke or allow any open flames during mixing, application or drying. • Ensure that CO2 or other dry chemical fire extinguishers are within easy access. • 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 48 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 90%. Coating should not become wet within 72 hours after application. Special precautions are to be taken when ambient and/or substrate temperatures are approaching, at, or above 105°F (41°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 Acrylic Base 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. • 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: Prior to the application of RE-ROOF Acrylic Base Coat, treat edges, seams, joints, metal flashing, penetrations and transitions with RE-ROOF Acrylic Flashing. Refer to the RE-ROOF Acrylic Flashing Technical Data Sheet for surface preparation, mixing and application instructions, WFT (wet mil thickness) requirements, approx. coverage, drying and recoat times. Allow to dry and pay close attention to recoat times. • Primer: Apply the appropriate primer to the field areas in preparation for RE-ROOF Acrylic Base Coat. Refer to the corresponding primer Technical Data Sheet for surface preparation, mixing and application instructions, DFT (dry film thickness) requirements, approx. coverage, drying and recoat times. Overlap the flashing according to the primer instructions. Allow to dry and pay close attention to recoat times. • First Base Coat: Apply the first coat of RE-ROOF Acrylic Base Coat in a monolithic application at a rate of 94 ft²/gallon to achieve a minimum of 17 mils WFT (wet film thickness). Use an airless sprayer, paint brush, or 3/8” nap phenolic resin core roller. Always backroll with a roller, even when spray-applying. RE-ROOF Acrylic Base Coat must be a uniformly thick, void-free, continuous membrane across the entire roof surface. Allow to dry and pay close attention to recoat times. Notes: Do not apply RE-ROOF Acrylic Base Coat at a rate of more than 1 gallon per 60 ft² (or more than 2 gallons per 120 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 Acrylic Base Coat in several thinner coats, allowing each coat to properly dry. 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. • Second Base Coat: Apply the second coat of RE-ROOF Acrylic Base Coat in a monolithic application at a rate of 94 ft²/gallon to achieve a minimum of 17 mils WFT (wet film thickness). RE-ROOF Acrylic Base Coat must be a uniformly thick, void-free, continuous membrane across the entire roof surface. Allow to dry and pay close attention to recoat times. Inspect the surface for damage prior to the application of RE-ROOF Acrylic Topcoat. Any surface damage must be repaired with RE-ROOF Acrylic Base Coat prior to the application of RE-ROOF Acrylic Topcoat. • First Top Coat: Apply the first coat of RE-ROOF Acrylic Top Coat. Refer to the RE-ROOF Acrylic Top Coat Technical Data Sheet for surface preparation, mixing and application instructions, WFT (wet film thickness) requirements, DFT (dry film thickness) requirements, approx. coverage, drying and recoat times. Allow to dry and pay close attention to recoat times. • Second Top Coat: Apply the second coat of RE-ROOF Acrylic Top Coat. Allow to dry and pay close attention to recoat times. • Third Top Coat: Apply the third coat of RE-ROOF Acrylic Top Coat. Allow to dry and pay close attention to recoat times. • Fourth Top Coat: Apply the fourth coat of RE-ROOF Acrylic Top Coat. Allow to dry. Drying: • Drying time for RE-ROOF Acrylic Base Coat is typically 24 hours at 75°F (24°C) and 50% relative humidity. • Apply second coat of RE-ROOF Acrylic Base Coat within a maximum of 48 hours after the first coat of RE-ROOF Acrylic Base Coat. • Apply RE-ROOF Acrylic Topcoat over RE-ROOF Acrylic Base Coat within a maximum of 48 hours after the application of RE-ROOF Acrylic Base Coat. • Allow to dry for at least 72 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. • Do not apply over spray polyurethane foam roofing. • High temperatures and high humidity will accelerate the drying time. Low temperatures and low humidity will extend the drying time.
Clean-up: Clean tools and equipment with mineral spirits immediately after use, while still fresh/wet. Hardened/dried material must be removed mechanically. Packaging: • 5-gallon pail (18.9 liters)
• 55-gallon drum (208 liters) Shelf Life & Storage: • 12 months in unopened, original packaging when stored at temperatures between 50°F and 80°F (10°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.
