Silicone coatings have been in the industry for a long time and are mostly used to cover and protect spray polyurethane foam (SPF) roofs due to the coatings permeability. Silicone roof coatings are the most flexible material available on this list, and they are often chosen for their ability to compensate for a building’s flexing with the change in temperature. Solvent-based silicone coatings: the best roof coating Silicone coated roof. This is because silicone coating warranties do not specifically exclude sections of the roof where ponding water occurs for more than 48 hours like TPO. Polyurethane succeeds with this material as well because it dries hard. One notable downside is it has little resistance to abrasion, so it’s not a good option if your roof has considerable foot traffic. Once a coating is in place, the maintenance is fairly straightforward. Silicone Resin (SR) Silicone resin coatings are single-component compounds that are often chosen for electronics that will be subjected to extreme temperature ranges. The testing standards required may vary by sealant chemistry- silicone or urethane. There are many types of elastomeric roof coatings such as acrylic, butyl, polyurethane or silicone. Some of these products may also be used as a top coat. These types of coatings are now used across a variety of roof membrane surfaces, including single-ply membranes and metal systems. The weight and composition of the fabric as well as the intended application are both important factors in coating choice. Urethane – Urethane roof coating is a solvent-based coating that is becoming more popular on the roofing market. Comparing Silicone vs. Acrylic Roof Coatings If you are in the market for a commercial roof coating , you may know there are plenty of different types to choose from. Acrylic Coatings. The Aldo product line includes Silicone, Acrylic and Polyurethane coatings for repair and restoration of a variety of roof systems including metal, membrane, and modified bitumen roofs. Both silicone and urethane coatings tend to be more expensive than other types of coatings, Ripps adds. Silicones are also very well suited for areas with extreme temperature ranges and where UV exposure is more frequent. Acrylic Coatings . Silicone Roof Coatings. The bright white color reflects UV rays, saving up to 35% in energy costs by reducing air conditioning usage to keep the facilities cool. Silicone roof coatings are a more cost-effective alternative than a TPO membrane installation. As one may guess, opinions aside, there are pros and cons that exist for both silicone and acrylic roof coatings. Waterproofness All coatings have their place in the market. The most significant difference of a silicone-based polymer when compared to a urethane polymer is the Si-O (silica-oxygen) bond as opposed to the C-O (carbon-oxygen) bond found in urethane sealants. Waterborne, acrylic coatings are the most popular. Silicone Roof Coatings. It is recommended for use on flat roofs that normally pond water such as built up, modified bitumen, concrete, EPDM, TPO and spray foam. Coolguard Roof Coating is a powerful, high Coolguard Roof Coating is a powerful, high performance roof sealer, made from a thick and single component acrylic urethane that is 100% elastomeric and will waterproof roofs and walls.
