Non-fibered roof coatings have asphaltic oils, which are protected from harmful intense sun rays by the reflective properties of aluminum. . This property is usually represented as a decimal between 0 and 1, with 0.65 being considered ideal for an elastomeric roof coating. So, if you still want a silicone product, Id recommend you go for this version. Silicones provide good weather resistance and rarely become hard or brittle. Polymeric coatings are made using any of various synthetic resins (polymers) as the primary waterproofing component. Therefore, when curing, let the non-fibered coating do so for at least 24-48 hours, and make sure there is proper air circulation before exposure to water or backfilling. But, they are best for sloppy roofs as they cant withstand ponding water. For a flat roof, always go for silicone coatings as they can withstand ponding water, and for sloppy-sided roofs, I recommend going for acrylic coatings.

A roof coating system (or roof restoration system), on the other hand, provides all the benefits of a new roof but for a fraction of the cost. 19 Flashing Cement. If you live in an environment that experiences extreme weather conditions and temperatures, you need to consider your coatings tolerance. # for 2 coats. Add to Cart. Meets the requirements of ASTM D 2824, Type III (Asbestos Free) Use: Used as a protective, reflective coating over built-up, SBS and APP modified bitumen roofs and approved substrates. However, a fibered aluminum roof coating does reflect almost 80% of the suns UV rays that would otherwise hit the roofs surface. Many building and commercial roof project owners often say that acrylic coatings cost less than silicone coatings. Gardner-Gibson Sta-Kool 17-Year Turbo-Dri Elastomeric Roof Coating, White, 5 Gal, Flexible White Acrylic Roof Coating, Reflective Finish Keeps Roof Cool, Resists .

They are highly reflective, fast-drying, and great for roof maintenance and repair. Because its solvent-based, silicone coating has superior UV stability and resistance to ponding water than elastomeric coating. The reflective properties of the aluminum are the ones responsible for the protection of the roof against the suns UV rays. Please note that this only applies under dry and warm weather conditions. Multiple passes may be required to achieve proper results. The moisture that accumulates in the roof sheathing generally comes from interior humidity which condenses on the underside of the roof sheathing. This adds extra years to the life and performance of the membrane. It can be used on various surface types and substrates such as; metal surfaces, built-up applications, modified bitumen, freshly sprayed polyurethane foam, and much more. In the case of a black EPDM roof, for instance, a reflective coating can reduce the normal afternoon temperature of the roof by up to 60F (34C). You can use silicone roof coating on various commercial roofing substrates, including; EPDM, TPO (can be directly applied as a base coat for these two), PVC, metal, built-up roofs, concrete, modified bitumen, and spray polyurethane foam. Most non-bituminous roof coatings are elastomeric. Fibered aluminum roof coatings are ultra-premium aluminum coatings that form a shiny, reflective, and rigid surface. A rubberized coating is a bituminous coating that contains a synthetic rubber. The inflexible nature of these coatings can lead to the development of bubbles, cracks, and gaps in a commercial roof. Silver Seal 300 4.75-Gallon Aluminum Reflective Roof Coating (3-year Limited Warranty) Model # 5175-A-30. Resistance to tearing is another inherent weakness. Many substrates wont. Asphalt emulsion is inexpensive and easy to work with. Silicone has high solid content (exceeds 90%), reducing the coating material needed for a single application. On the other hand, silicones will last significantly longer (between 15-20 years). View.

Some types of coatings are subject to environmental and health restrictions. The reflective coating in fibered coatings reinforces the strength, thus protecting low and steep slope roofs from harmful UV rays damage and at the same time supporting overall energy efficiency. Its a lot like adding ethanol to gasoline that way. Acrylic roofing coats will usually last for about ten years before they deteriorate. Most elastomeric coatings typically measure anywhere between 250-900%. Many homeowners believe that choosing a roof coating is challenging. A butyl coating system is suitable for a variety of commercial roof surfaces including metal, modified bitumen, single-ply, built-up roofs, and spray polyurethane foam. The thickness that fibered roof coatings have ensures that they reflect almost 80% of the UV light initially hitting the flat roofs surface. On the other hand, silicone will be dry to the touch within 30 minutes of application but will take 24 hours to cure. Up to 20-year Material, Labor & Workmanship Gold Seal systems warranty. Its important to note that higher permeability does not equate to inferior weather resistance. On the roof, smoother surfaces like metal will achieve better coverage rates and require less product. On the other hand, silicone coatings are noticeably more difficult to apply. If, according to the factors considered, the pros of silicones outweigh the cons, go for it, and if the reverse applies, then pick acrylic coatings. On the other hand, silicone roof coatings have two main uses and benefits.
