Designed to Endure Guam's Tropical Climate
Roofseal Tropical Roof Coating works great over:- Mineral surface and smooth surface modified bitumen
- Ultraroof 900 Primer
- Spray polyurethane foam
- Smooth surface built-up roof (BUR)
- Mineral surface built-up roof (BUR)
- Granulated asphaltic surfaces
- Hot-mopped asphalt cutback
- Emulsion tar and gravel
- Metal and galvanized
- Roofseal Tropical Roof Coating was designed as a single-part water-based coating with the highest performance in coastal, temperate, humid, hot, and extreme alkaline environments. Roofseal Tropical creates a tough, long-lasting protective membrane that remains flexible Over time even under adverse conditions. lts elongation and tensile strength provide unsurpassed resistance to maintenance traffic, weather conditions, and wear.
- Its proprietary formula features copolymer elastomeric resins to produce a seamless, flexible, durable membrane that displays exceptional weatherability and UV resistance. Because it is a high-solids coating, Roofseal Tropical has low shrinkage, allowing it to bridge hairline cracks and provide protection against new cracks forming.
Roofseal Tropical Roof Coating is one of
- Ultraroof 900 Primer
- Acrylastic 510 Roof Coating
- Roofseal Acrylic Elastomeric Roof Coating

Applications & Uses
- Applications & Uses
Surface preparation
- Remove all contaminants and loose material, such as dust, dirt, oil, silicone, release agents, wax, mildew, salt deposits, and chalky or loose coating. Check the entire roof and thoroughly powerwash it.
- Polyurethane foam: Repair all cracks and holes in foam by filling with Acryflex 1210 and embedding polyester tape or fabric into wet coating. New urethane foam surfaces that require no cleaning should be coated within the time-frame recommended by the manufacturer.
Application procedure
- Stir Roofseal Tropical until uniformly blended, but avoid excessive mixing to prevent air entrapment. Flush all equipment with water before use. Apply a wet coat in even, parallel passes, overlapping each pass 50% to avoid holidays, bare areas, and pinholes. Cross-roll or spray at a right angle to the first pass. Apply 1 coat of Roofseal at 1 gallon per 100 square feet, DFT 8 mils. Allow 4-8 hours to dry. Use rule-of-thumb test prior to installing the next coat: when one's thumb is pressed firmly into the coating, none of the coating will adhere to the thumb. Apply second, third, and fourth coats, per system specifications. For additional durability, roofing granules may be broadcast into the final coating application at the rate of 35-40 ounces per 100 square feet.
- Clean up: Clean all equipment with detergent and water.
Application equipment
The following is a guide; suitable equipment from other manufacturers may be used. Changes in pressure, tip size, and equipment may be needed for proper spray characteristics.
- Airless: Standard equipment such as Graco Bulldog Hydra Spray 30 or 45:1 pump with a 0.025-0.031 inch reversible fluid tip.
- Conventional: Industrial equipment such as Binks 11:1 Saturn pump or equivalent with air control cut-off, a material hose 3/4 inch ID minimum, and a heavy air hose 1/2 inch ID and 50-75 psi air pressure minimum.Heavy mastic spray gun such as Binks 7E2 with 1/4 inch fluid tip or larger and slotted nozzle.
- Brush or Roller: Suitable for waterborne coating. Multiple coats may be required to achieve specified DFT. Roller nap will vary according to substrate texture and thicknss of coat typically 3/4 inch nap will work.
