What Are Elastomeric Roof Coatings?
Elastomeric roof coatings are a coating applied to roofs to protect them from the elements. These coatings are made of rubber or latex and are designed to be flexible, allowing them to expand and contract with the roof as it moves. Moreover, this flexibility makes elastomeric coatings ideal for protecting roofs from the elements, as they can withstand significant temperature changes and movement without cracking or breaking.Guide to Installing Elastomeric Coatings:
Remove Debris
One of the most critical steps in installing elastomeric coatings is to ensure that your roof is clean of debris. This can be a relatively simple or complex task depending on your roof type. You can either use a vacuum, power broom, or a scraping method to do this. No matter what type of roof you have, taking the time to prep your surface will ensure a better final product.Use a Power Washer
Before enjoying the benefits of elastomeric coatings, you need to ensure your roof is clean. This is especially important for flat and metal roofs, which can be more susceptible to leaks. The best way to clean your roof is with a power washer, which will remove all the dirt, debris, and moss that can accumulate over time. Once your roof is clean, you can apply a silicone coating to help prevent leaks and extend the life of your roof. Elastomeric coatings are a great way to protect your investment, but they must be applied to a clean surface to be effective. However, with some prep work, you can ensure that your elastomeric coatings will last for years.Repair Cracks and Blisters
Before installing elastomeric coatings, it is vital to repair any cracks or blisters that may be present. These can impact the performance of the coating and may lead to other elastomeric coatings delaminating. Once the repairs are complete, allowing the area to dry completely is vital before continuing with the installation process.Reinforce Localized Problem Areas
Localized problem areas (such as blistered areas) can be reinforced by embedding T272 polyester reinforcing fabric in an AcryShield base coat. This ensures that the fabric will not degrade over time and provides a high-strength bond between the fabric and the base coat.Apply the Silicone Roof Coating
After all the preparation, you can now start the process of applying the silicone roof coating. Using a 1/4″ Nap Roller for this task is recommended, but you can also spray it. Again, start at one roof edge and work your way across, evenly distributing the coating. Here’s what the process should look like:- Coat the roof evenly with AcryShield using a spray or roller.
- Give the coating 8 to 24 hours to dry completely.
- After it has dried, apply a top coat of AcryShield in a crosshatch pattern.
- Let the second coat dry before allowing anyone onto the roof.
The Rate Per Gallon Per 100 Square Feet
Asphalt / BUR / Mod Bit We will use the ARM (ACRYSHIELD Roof Management System) for the entire roof. It uses 3 gallons of ACRYSHIELD per 100 square feet and needs to be applied evenly in two coats:- 1.5 AcryShield A503 base coat per 100 square feet
- 1.5 AcryShield A400 top coat per 100 square feet
- AcryShield A502 base coat – 1 gallon
- AcryShield A500 top coat- ½ gallon
- AcryShield A502 base coat – 1.5 gallons per 100 square feet
- AcryShield A500 top coat – 1.5 gallons per 100 square feet
- AcryShield A510 base coat – 1.5 gallons per 100 square feet
- AcryShield A400/A510 top coat – 1.5 gallons per 100 Square feet
