The RE-ROOF System is an eco-friendly, <br />reliable solution for new roofs and cost-effective option for extending the <br />life of existing roof systems. <br />Typical Applications: <br />• As the base coat for Aquafin’s RE-ROOF Urethane System. <br />• Apply RE-ROOF Urethane Base Coat over a wide variety of common <br />roof surfaces that have been primed with the appropriate Aquafin <br />primer. <br />Advantages: <br />• Quick & easy application <br />• Excellent resistance to chemicals, acids, and oils <br />Priming and Surface Preparation: <br />• RE-ROOF Urethane Base Coat requires a primer for all applications. <br />Select the appropriate primer(s) based on the type of substrate(s) and <br />surface material(s) from the list below. <br />• BUR: use RE-ROOF Primer WB <br />• Concrete: use PRO-Tekt SP (Sealant Primer) <br />• EPDM: use RE-ROOF EPDM Treatment <br />• Galvanized Steel: use PRO-Tekt SP (Sealant Primer) <br />• Masonry: use PRO-Tekt SP (Sealant Primer) <br />• Modified Bitumen: use RE-ROOF Primer WB <br />• Oil Contaminated Concrete: use VAPORTIGHT COAT®-SG2 <br />• Polyurethane: use RE-ROOF Primer PO <br />• PVC: use RE-ROOF Primer PO <br />• TPO: use RE-ROOF Primer PO <br />• Wood (trim only): use PRO-Tekt SP (Sealant Primer) <br />• Refer to the corresponding primer Technical Data Sheet for surface <br />preparation instructions and other important information. <br />• Ensure RE-ROOF Urethane Base Coat is applied to primed substrate <br />within the required recoat times. <br />• Primed substrates must be dry, clean and free of dirt, dust, grease, oil, <br />and other foreign substances that could interfere with adhesion.</p> <p>Check our website for the latest version of the Technical Datasheet. <br />www.aquafin.net</p> <p>RE-ROOF Urethane Base Coat</p> <p>All data are averages of several tests under laboratory conditions. In practice <br />climatic variations such as temperature, humidity, and porosity of substrate may <br />affect these values.</p> <p>Adhesion Test: <br />To ensure a successful application, always perform several adhesion tests <br />(ASTM D-903) with RE-ROOF Urethane Base Coat to ensure that the <br />primer has successfully bonded to the roof substrate, and the primed roof <br />substrate will accept RE-ROOF Urethane Base Coat. Do not proceed with <br />the application of RE-ROOF Urethane Base Coat before adhesion testing. <br />Jobsite Preparation: <br />• Take all necessary precautions to ensure safety. <br />• Cover all intake vents near the work area. <br />• Minimize or exclude all personnel not directly involved with the <br />application. <br />• Follow appropriate measures to prevent any sparks. <br />• Do not weld, smoke or allow any open flames during mixing, <br />application or curing. <br />• Ensure that CO2 or other dry chemical fire extinguishers are within easy <br />access. <br />• Only proceed with application when ambient temperature is minimum <br />of 50°F (10°C) and falling, and more than 6°F (3°C) above dew <br />point. 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 />Page 1 of 3</p> <p>(03/14/23/EK/AC)</p> <p>RE-ROOF Urethane Base Coat <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 Urethane Base Coat. <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. <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: Prior to the application of RE-ROOF Urethane <br />Base Coat, treat edges, seams, joints, metal flashing, penetrations <br />and transitions with a RE-ROOF urethane flashing. Refer to the <br />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 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 RE-ROOF Urethane Base Coat in <br />a monolithic application at a rate of 94 ft²/gallon to achieve a minimum <br />of 17 (± 1) mils WFT (wet film thickness). Use an airless sprayer, brush, <br />or phenolic resin core roller. RE-ROOF Urethane Base Coat must be a <br />uniformly thick, void-free, continuous membrane across the entire roof <br />surface. Allow to cure and pay close attention to recoat times. <br />Notes: Do not apply RE-ROOF Urethane Base coat at a rate of more <br />than 1 gallon per 50 ft² (or more than 2 gallons per 100 ft²). Sagging <br />and running is more likely to occur on sloped, slanted and vertical <br />areas especially when the coating is applied to thick. Thicker coating <br />applications also increase the chances of bubbles, blisters and/or <br />pinholes. If necessary, apply RE-ROOF Urethane Base Coat in several <br />thinner coats, allowing each coat to properly cure. <br />• Second Base Coat: Apply the second coat of RE-ROOF Urethane Base <br />Coat in a monolithic application at a rate of 94 ft²/gallon to achieve a <br />minimum of 17 (± 1) mils WFT (wet film thickness). RE-ROOF Urethane <br />Base Coat must be a uniformly thick, void-free, continuous membrane <br />across the entire roof surface. Allow to cure and pay close attention to <br />recoat times. Inspect the surface for damage prior to the application of a <br />RE-ROOF urethane top coat. Any surface damage must be repaired with <br />RE-ROOF Urethane Base Coat prior to the application of the top coat. <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)</p> <p>meets the stated requirements. See coverage chart for minimum WFT (wet <br />film thickness) mil guidelines and DFT (dry film thickness) mil requirements. <br />• First Top Coat: Apply the first coat of a RE-ROOF urethane top coat. <br />Refer to the corresponding RE-ROOF urethane top coat Technical Data <br />Sheet for surface preparation, mixing and application instructions, dry <br />mil thickness requirements, approx. coverage, curing and recoat times. <br />Allow to cure and pay close attention to recoat times. <br />• Second Top Coat: Apply the second coat of a RE-ROOF urethane top <br />coat. <br />Curing: <br />• Curing time for RE-ROOF Urethane Base Coat is typically 16 hours at <br />75°F (24°C) and 50% relative humidity. <br />Notes: Mix RE-ROOF Urethane Base Coat 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. <br />When RE-ROOF Urethane Base Coat 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 Urethane Base Coat within a maximum <br />of 48 hours after the first coat of RE-ROOF Urethane Base Coat. <br />Note: When RE-ROOF Urethane Base Coat is mixed with RE-ROOF <br />Urethane Accelerator, apply the second base coat within a maximum of <br />24 hours. <br />• Apply a RE-ROOF urethane top coat over RE-ROOF Urethane Base <br />Coat within a maximum of 48 hours after the application of RE-ROOF <br />Urethane Base Coat. <br />Note: When RE-ROOF Urethane Base Coat is mixed with RE-ROOF <br />Urethane Accelerator, apply the RE-ROOF urethane top coat within a <br />maximum of 24 hours. <br />• Allow to cure for at least 24 hours [based on 75°F (24°C) and 50% <br />relative humidity] before permitting light pedestrian traffic on the finished <br />surface. <br />• If more than 48 hours has passed after the application of RE-ROOF <br />Urethane Base Coat [24 hours if RE-ROOF Accelerator is used], reprime with RE-ROOF Primer PO before proceeding with the application <br />of a second coat of RE-ROOF Urethane Base Coat or the application of <br />a RE-ROOF urethane top coat. <br />• Allow to cure for at least 24 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 />5-gallon pail (18.9 liters) <br />55-gallon drum (208 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).</p> <p>Check our website for the latest version of the Technical Datasheet.
