Various coating materials are available in the market for strengthening the durability of the roof. The method of application and the quality differs with every coating material. All the coatings are not compatible with all the roof surfaces. The pre-application process of the coating also differs and needs to be done according to the requirements of the coating manufacturer. Let us discuss some ways of coating the roof for increasing its strength.
With the dissolution of 100 percent silicone, the coatings are created with high solids. The coating materials are elastic and provide adhesion. A huge weather resistance can be observed and the silicone never becomes brittle or hard in any conditions. This type of coating has gained a huge market share in the commercial market of Resolve Roofing in the last decade. Ponding water should be resisted by the silicone coating, unlike the other coating which cannot withstand accumulated water. This coating also helps in proper protection from ultraviolet rays.
There are some drawbacks like holding dirt on the surface and losing the reflectivity with time, and only a few materials can be used for applying on the silicone surface.
There are several ways to seal a metal roof and acrylic coatings are one of them. Superior protection can be provided from ultraviolet rays with the help of this coating. The coatings can be used for different roof membrane surfaces including the metal systems and the single-ply membranes. Resistance to damage from hail and radiation can be acquired with inherent flexibility. When the coating has been done appropriately, the surface temperature can be decreased to 20 degrees F and when exposed to direct sunlight can go up to 85 degrees F.
Made with 100% pure acrylic and can be applied for more than one coat. Depending on the coverage rates, most of the manufacturers provide warranties. Additional coverage will be required for the extended warranties. During precipitation or freezing temperatures, the acrylic coating should not be applied. The curing time of this coating is dependent on the weather and should not be done in cold weather and high humidity. The ideal weather for curing is low humidity with warm weather.
If you possess existing roof membranes, you can apply different layers of coating. Aliphatic and aromatic are two different types of polyurethane coating. The best rates and high foot traffic resistance can be offered by this type of coating. It remains clean and the color stays longer compared to other coatings says Chiang Rai Times.
Rubber Membrane System
The life of the existing roof can be extended with the help of this fluid-applied rubber membrane coating. The rubber material helps in combining the features of rubber with the waterproof characteristics of asphalt.
Irrespective of the facility of roof coating, the managers select the adhesives and liquids depending on the weather and the location. The coatings are generally applied on the existing roof surface for strengthening the roof. As all the coating materials have a limited period of shelf-life, proper storage of the on-site material is very important.
