How to Apply Elastomeric Roof Coatings
Preparation
Step 1: Clean
Elastomeric coating is a popular choice for flat roofs and metal roofs. It is a seamless, waterproof membrane that can extend the life of your roof and protect it from ponding water, UV rays, and extreme temperatures. However, before applying an elastomeric coating, you must clean the roof surface to remove any dirt, debris, or moss. Cleaning the surface will ensure that the elastomeric coating adheres properly and creates a tight seal. You can use a power washer or a soft-bristle brush to remove any build-up on the roof. Once the surface is clean, you can apply the elastomeric coating according to the manufacturer’s instructions. With proper preparation, an elastomeric coating can provide an effective barrier against the elements and help prolong your roof’s life.Step 2: Repair
Elastomeric coating is highly flexible, which helps it to resist cracking and peeling. Before applying an elastomeric coating, it is essential to repair any cracks or holes in the roof using a sealant. This will ensure that the coating adheres properly and does not allow water to seep. In addition, other elastomeric coatings should be removed before applying a new coating layer. Silicone-based coatings are tough to remove, so it is essential to consult a professional if you are unsure how to do this. Finally, it is best to apply the silicone roof coating in the spring or fall months, as the extreme temperatures in the summer and winter can cause the coating to fail.Application
Step 3: Apply
Applying a silicone roof coating is a great way to extend the life of your roof and prevent leaks. Silicone coatings are highly resistant to UV light, impact, and extreme temperatures, making them ideal for protecting roofs from the elements. When applying silicone roof coatings, it’s essential to use a brush, roller, or sprayer designed explicitly for the product. This will ensure that the coating is evenly applied and that there are no missed areas. Here are what you need to remember:- First, evenly spread a base coat of AcryShield across the entire roof using either a sprayer or roller.
- For best results, allow the coating to dry for 8-24 hours.
- Lastly, put on a top coat of AcryShield using a crosshatch pattern.
Step 4: Dry
Silicone coatings are durable and resistant to sunlight, making them ideal for use on outdoor surfaces. However, allowing the silicone coating to dry completely before walking on it or allowing pets onto it is essential. If the silicone coating is not given enough time to dry, it may not adhere properly to the surface and could start to peel off. Allowing the silicone coating to dry completely before using the surface will help ensure that it lasts many years.Silicone Roof coating Rate per Gallon per 100 Square Feet
