Ask Your Roofing Contractor: Silicone or Acrylic Roofing Coating
When we are investing in a roof, we want our investment to be protected. For that, we look for roof coatings that provide us the maximum value for our purchase. Amongst the many spray based roof coatings, silicone and acrylic coatings are most extensively used. When it comes to selecting between the two, we should be well informed and as such, it is advisable to seek our roofing contractor for help.
Hello, Roofing Contractor on the Line?
Acrylic Roofing Coating
Acrylic coating is a water based roof coating, having less odor and significantly cheaper than silicone coating. Acrylic coating can only be applied in temperatures above 50 degree Fahrenheit. They are elastomeric in nature which makes them a convenient option in fluctuating temperatures. They are highly reflective, hence offering an effective and affordable roof cooling option.
One big disadvantage of acrylic roofing coating is that because of low tensile strength, they are subjected to wear and tear easily. Plus, they are not ideal for tackling with water ponding situations.
Silicone Roofing Coating
Silicone coating is solvent based roof coating, having more durability than acrylic and other water based coatings but also more expensive. They do not require a primer but in cases of re-application, we have to make sure that only compatible silicone is used or the previous layer needs to scraped-off. They can be applied on cold days unlike acrylic coating and has cure time far lesser than that of acrylic coating, which may take up to 7 days to dry.
Besides that, silicone is more resistant to UV as compared to acrylic, but far softer which can make it vulnerable to footprints in case of heavy traffic. The water proofing characteristic of silicone coating is also found to be superior to acrylic coating.
What we choose entirely depends on our needs and budget. Silicone roofing although more expensive as the first time upfront cost but it has advantages that are more tempting than the overall package of what acrylic coating has to offer. If you are stuck and want professional help, you can always count on the expertise of our roofing contractors.
