Temperatures must be maintained within this range for at least 24 <br />hours after the installation. Do NOT proceed with application when the <br />temperatures drop below 50°F (10°C), if precipitation is expected, or <br />if humidity is at or above 80%. Coating should not become wet within <br />48 hours after application. Special precautions are to be taken when <br />ambient and/or substrate temperatures are approaching, at, or above <br />90°F (32°C) and it may be necessary to limit material application to <br />evening hours. <br />• Hot surfaces should be cooled and shaded while cold surfaces should <br />be heated and sheltered. <br />Mixing: <br />• Condition material to 70°F to 80°F (21°C to 27°C) prior to mixing <br />and application. <br />• Use chemical resistant (Nitrile) gloves and goggles when mixing or <br />applying RE-ROOF White Urethane Top Coat HS. <br />• Open container and mix at slow speeds (not exceeding 500 rpm) <br />for 1–2 minutes to evenly distribute pigments and other ingredients <br />that may have settled, until a homogeneous mixture is achieved.</p> <p>Page 1 of 3</p> <p>(03/14/23/EK/AC)</p> <p>RE-ROOF White Urethane Top Coat HS <br />Thoroughly scrape sides of pail as material is mixed. Boxing material is <br />recommended to ensure color uniformity. <br />• Use caution not to whip air into the material as this may result in pinhole <br />blisters and/or shortened pot life. Do not mix in an up and down motion. <br />Application: <br />Read all instructions thoroughly prior to installation. <br />• Flashing Treatment: Treat edges, seams, joints, metal flashing, <br />penetrations and transitions with a RE-ROOF urethane flashing. Refer to <br />the corresponding RE-ROOF urethane flashing Technical Data Sheet for <br />surface preparation, mixing and application instructions, dry mil thickness <br />requirements, approx. coverage, curing and recoat times. Allow to cure <br />and pay close attention to recoat times. <br />• Primer: Apply the appropriate primer to the field areas in preparation <br />for a RE-ROOF urethane base coat. Refer to the corresponding primer <br />Technical Data Sheet for surface preparation, mixing and application <br />instructions, approx. coverage, curing and recoat times. Overlap the <br />flashing according to the primer instructions. Allow to cure and pay close <br />attention to recoat times. <br />• First Base Coat: Apply the first coat of a RE-ROOF urethane base coat. <br />Refer to the corresponding RE-ROOF urethane base coat Technical <br />Data Sheet for surface preparation, mixing and application instructions, <br />dry mil thickness requirements, approx. coverage, curing and recoat <br />times. Allow to cure and pay close attention to recoat times. <br />• Second Base Coat: Apply the second coat of a RE-ROOF urethane <br />base coat. Allow to cure and pay close attention to recoat times. <br />Inspect the surface for damage prior to the application of RE-ROOF <br />White Urethane Top Coat HS. Any surface damage must be repaired <br />with a RE-ROOF base coat prior to the application of RE-ROOF White <br />Urethane Top Coat HS. <br />• First Top Coat: Apply the first coat of RE-ROOF White Urethane Top <br />Coat HS in a monolithic application at a rate of 94 ft²/gallon to <br />achieve a minimum of 17 (± 1) mils WFT (wet film thickness). Use an <br />airless sprayer, brush, or phenolic resin core roller. RE-ROOF White <br />Urethane Top Coat HS must be a uniformly thick, void-free, continuous <br />membrane across the entire roof surface. Allow to cure and pay close <br />attention to recoat times. <br />Notes: Do not apply RE-ROOF White Urethane Top Coat HS at a rate <br />of more than 1 gallon per 100 ft². Sagging and running is more likely to <br />occur on sloped, slanted and vertical areas especially when the coating <br />is applied to thick. Thicker coating applications also increase the chances <br />of bubbles, blisters and/or pinholes. If necessary, apply RE-ROOF White <br />Urethane Top Coat HS in several thinner coats, allowing each coat to <br />properly cure. <br />• Second Top Coat: Apply the second coat of RE-ROOF White Urethane <br />Top Coat HS in a monolithic application at a rate of 94 ft²/gallon to <br />achieve a minimum of 17 (± 1) mils WFT (wet film thickness). RE-ROOF <br />White Urethane Top Coat HS must be a uniformly thick, void-free, <br />continuous membrane across the entire roof surface. <br />Notes: Always verify that the proper WFT (wet film thickness) has been <br />achieved by measuring each coat using a wet film gauge. As a minimum, <br />it is recommended to check the mil thickness in every corner, plus the <br />center areas of the roof. Large areas will require many check points. When <br />applying multiple, thinner coats, verify that the total DFT (dry film thickness) <br />meets the stated requirements. See coverage chart for minimum WFT (wet <br />film thickness) mil guidelines and DFT (dry film thickness) mil requirements. <br />Total System Thickness (field areas): 54 mils DFT <br />Notes: Total system thickness requirement excludes additional dry mils of <br />primer coat(s), and flashing.</p> <p>Curing: <br />• Curing time for RE-ROOF White Urethane Top Coat HS is typically 16 <br />hours at 75°F (24°C) and 50% relative humidity. <br />Notes: Mix White Urethane Top Coat HS with RE-ROOF Urethane <br />Accelerator when faster curing times are desired. Refer to RE-ROOF <br />Urethane Accelerator Technical Data Sheet for more information. When <br />RE-ROOF White Urethane Top Coat HS is mixed with RE-ROOF Urethane <br />Accelerator, curing time is approx. 8 hours [based on 75°F (24°C) and <br />50% relative humidity]. <br />• Apply second coat of RE-ROOF White Urethane Top Coat HS within <br />a maximum of 48 hours after the first coat of RE-ROOF White Urethane <br />Top Coat HS. <br />Note: When RE-ROOF White Urethane Top Coat HS is mixed with REROOF Urethane Accelerator, apply the second top coat within a maximum <br />of 24 hours. <br />• If more than 48 hours has passed after the first application of RE-ROOF <br />White Urethane Top Coat HS [24 hours if RE-ROOF Accelerator is <br />used], re-prime with RE-ROOF Primer PO before proceeding with the <br />second application of RE-ROOF White Urethane Top Coat HS. <br />• Allow to cure for at least 48 hours [based on 75°F (24°C) and 50% <br />relative humidity] before permitting light pedestrian traffic on the finished <br />surface. <br />Limitations: <br />• Do not dilute under any circumstance. <br />• High temperatures and high humidity will accelerate the cure time. Low <br />temperatures and low humidity will extend the cure time. <br />Clean-up: <br />Clean tools and equipment with Methyl Ethyl Ketone (MEK), Xylene, or <br />similar product immediately after use. Cured material must be removed <br />mechanically. <br />Packaging: <br />RE-ROOF White Urethane Top Coat HS is packaged in a 5-gallon pail <br />(18.9 liters). <br />Shelf Life & Storage: <br />• 12 months in unopened, original packaging when stored at <br />temperatures between 40°F and 80°F (4.4°C to 27°C). <br />• Keep containers closed, store in a dry, cool place away from heat, <br />direct sun, sparks, open flame, and moisture. <br />• Protect material from freezing. <br />Note: <br />Proper application is the responsibility of the user. Field visits by AQUAFIN <br />personnel are for the purpose of making technical recommendations and <br />not for supervising or providing quality control on-site. <br />Safety: <br />Refer to SDS.
