This best waterproofing paint for roof available in market. Truworth imports this from Rust-Oleum USA. (Best manufacturer of surface treatments). Rust-Oleum 980 Waterproofing Silicone Roof Coating Paint is based on silicone that offers long term protection from weather. Services that paint offer are waterproofing, weatherproofing, resist UV rays, and more. Do you know it is not necessary to use primer when you apply single coating of 980 silicone paint? It works best on spray applied polyurethane foam, concrete, aged acrylic coatings, aged single-ply roofs, asphalt built-up roof, metal, RV, over existing roof coating, and more.

How to Apply Rust-Oleum 980 Waterproofing Silicone Roof Coating Paint
All surfaces must be clean and free from dirt, grease, oil, mold, algae, loose granules, loose paint, rust, excess chalk and other foreign matter which could prevent proper adhesion. Use a high pressure wash and stiff bristle brush or broom scrub the surface. An appropriate non-filming cleaner should be used to remove all grease or oily deposits.
EPDM roofs may require aggressive power washing and may need to be cleaned twice to remove all surface contamination. Rinse thoroughly and allow to dry. Seams, fasteners, roof penetrations and any roof defects should be repaired and sealed prior to applying the topcoat.
Do not thin or alter product. Apply only when air, material,and surface temperatures are between 32-120ºF (0-49ºC). For cold weather application (below 55ºF), store unopened container indoors for 24 hours prior to application. Do not apply if rain is expected in less than 2 hours. Mechanically mix prior to application and during use. Avoid entraining air when mixing. Apply with a brush, ¾” nap roller or spray equipment. For one coat application, apply at a minimum rate of 1.5 gallons per 100 square feet (25 mils wet). Coating must be applied uniformly and without pinholes. The dry film thickness (DFT) will be approximately 24 mils. A second coat may be required on rough or uneven surfaces. For a two coat application, apply a base coat at a minimum rate of 1 gallon per 100 square feet (16 mils wet). Apply a second coat at the same rate. Allow 2-4 hours before applying a second coat. Apply perpendicular to the first coat. The dry film thickness (DFT) will be 15 mils per coat.
