PRODUCT NO. 4000 TUFF-COAT is an ultra white 100% acrylic elastomeric roof coating with state of the art bleed-blocking technology. This premium grade roof coating is designed for maximum protection against sun and extreme weather. Its bright white finish enables it to deflect the sun’s heat and harmful UV rays, protecting the roof substrate and extending life expectancy. PRODUCT NO. 4000 TUFF-COAT forms a thick, rubber-like shield that expands and contracts greater than 250% to prevent roof damage. PRODUCT NO. 4000 TUFF-COAT resists cracking, peeling, and mildew while offering unbeatable weatherproof protection and excellent resistance to ponding water. USES: PRODUCT NO. 4000 TUFF-COAT with state of the art bleed-blocking technology can be used over asphalt, tar, hotapplied built-up roofing, granulated cap sheet and metal roofing systems. PRODUCT NO. 4000 TUFF-COAT can be directly applied over most previously coated roof surfaces. PRODUCT NO. 4000 TUFF-COAT should not be applied over 100% silicone. When applying over aluminum roof coating, exposed spray polyurethane foam, TPO, or EPDM follow surface preparing instructions below. SURFACE PREPARATION: Roof substrates must be clean, dry, free of all debris, and any contaminants which would impede proper adhesion. A pressure wash is recommended, if a pressure washer is not available a cleaning agent should be used in conjunction with hose and broom washing. In addition to pressure washing, a wire brush should be used to remove any surface rust on metal roofing systems. Metal panels where the structural integrity has been compromised should be removed and replaced with like panels. A bleach and water solution (1 part bleach to 2 parts water) should be used to treat any roof areas that have mildew or algae. All roof surfaces should be thoroughly cleaned and allowed to dry completely prior to application of any Tucson Rubberized Coatings products. Over aluminum roof coating, one coat of PRODUCT NO. 295-G STAIN SHIELD or PRODUCT NO. 297-X XTREME must be applied prior to the application of PRODUCT NO. 4000 TUFF-COAT. All large cracks and seams should be repaired by embedding one layer of polyester fabric between two layers of PRODUCT NO. 501-W-P ACRYLIC MASTIC or PRODUCT NO. 510 REINFORCED ACRYLIC MASTIC prior to application of PRODUCT NO. 4000 TUFF-COAT. To achieve proper adhesion over TPO, PVC, EPDM or exposed spray polyurethane foam, one coat of PRODUCT NO. 297-X X-TREME must be applied prior to any Tucson Rubberized Coatings repair or top coat products. APPLICATION: Proper protective clothing and PPE should be worn when applying products. It is normal to see a small amount of separation when first opening a pail. If necessary, gently mix the product with a roller frame or paddle mixer, being careful to not introduce air into the product during mixing. Product can be applied by roller (3/4 – 1 1/4” nap), brush, and spray equipment capable of 2000 – 3000 PSI and 1 – 3 GPM of output. For best results when spraying, an 8-31 – 8-41 reversible spray is recommended. Do not dilute product. Tucson Rubberized Coatings Products should not be applied when freezing temperatures or rain is expected within 24 hours of completed application. During application, roof surface temperatures should be between 40 and 115 degrees Fahrenheit, with no moisture present. RECOMMENDED COVERAGE RATES (completed in 2 coats): PRODUCT NO. 4000 TUFF-COAT should be applied at a minimum rate of 1 – 1 ½ gallons per 100 square feet of roof surface, per coat. The first coat should be allowed to cure approximately 24 hours before a second coat is applied. The second coat should be applied perpendicular to the first coat (cross hatch application). Two coats applied at the specified rate are required to obtain a Limited Manufacturer Material Warranty. Coverage rates will depend on porosity of the roofing substrate. Final Dry Film Thickness (DFT) will determine the overall success and warranty term. DO NOT APPLY TO ANY SURFACES THAT CONTAIN SILICONE. STORAGE: Product should be stored in a clean and dry area, away from direct sunlight and protected from freezing. CLEAN-UP: Clean brushes, tools and other equipment with warm soapy water immediately after use. Dried film may require paint remover.
