The Need for Elastomeric Coating 

What, exactly, is Elastomeric Coating? 

Before understanding the need for Elastomeric coatings for roof, let’s first look at its meaning. 

Elastomeric coating for roofs is fluid-applied coatings made of silicone or acrylic. After drying on the roof, they become strong, highly durable, and elastic membranes.

As mentioned earlier, roofs face numerous challenges over time, such as leaks, cracks & a decrease in efficiency. 

Common Problems in Roofs

Leaks: They can result in water damage & compromise the structural integrity of a whole building. 

Cracks: Harsh weather conditions, such as strong winds or heavy snow, can cause cracks in the property, potentially allowing water penetration. 

Low Efficiency: Over time, roofs often lose their efficiency, resulting in increased heating or cooling costs. 

A Go-To Solution for All Types of Roof Issues

Elastomeric coatings are the go-to solution for all types of roofing issues. They are not just a quick fix; they provide long-lasting protection for your roof. These coatings have everything- top-notch durability, flexibility, and versatility. By investing in elastomeric coatings, you’re not only addressing existing issues but also proactively extending the life of your roof and protecting your investment.

How do you apply elastomeric roof coatings properly? 

To ensure proper application of elastomeric coating for roofs, you require careful preparation and execution. Follow the steps below for proper application.

Step #1: Inspection of the Existing Roof & Cleaning 

Before starting anything else, inspect the existing roof and repair any cracks or damaged areas (if there are any). Moreover, fill gaps and seams with appropriate sealants. After inspection of the existing roof, proceed with cleaning the roof surface to remove dirt, debris & dust, or any loose material. 

Expert Advice:

Use a stiff-bristle brush to clean. For extremely dirty areas, use a power washer, keeping it 18 inches away from the roof surface. Also, consider having a local roofer inspect your existing roof. 

Step #2: Collecting Important Tools & Equipment 

To successfully apply Elastomeric coating for roofs, ensure you’ve state-of-the-art equipment and tools. Assemble the essential tools such as: 



Push Brooms


Power Drill

Sprayer Equipment 

Besides this, also consider personal safety gear, including 


Work Boots 



& Safety Harnesses 

Expert Advice: 

If you don’t have all this equipment, consider renting them. 

Step #3: Determining the Use of Primer through Field Adhesion Test

Some elastomeric coatings may require a primer to enhance adhesion.

But how would you find out if your elastomeric coating for roof requires a primer application? 

There’s nothing to worry about. 

All you need is a Field Adhesion Test. 

To conduct a field adhesion test, follow these methods. 

  1. Apply a primer to the designated area where the polyester reinforcing fabric will be attached. Then, carefully place the polyester reinforcing fabric onto the primed surface. 
  2. Now, apply a second coat of primer over the attached polyester fabric, leaving a two-inch portion uncoated. 
  3. Wait for the entire coated area, including the attached fabric, to dry for at least 24 hours. 
  4. After the drying period, perform a fabric pull test. You need to grasp the two-inch uncoated segment of the fabric and carefully pull the adhesion strength. 
  5. Now, evaluate the test. If the coating clearly separates from the substrate during the pull test, it may indicate the need for primer application. However, if the primer remains on the surface and the coating detaches, get assurance that primary application is not necessary. 

Expert Advice:

Take into account the local climate conditions during application. Extreme temperatures or adverse weather can affect drying times and adhesion. Thus, consider applying an elastomeric coatings for roofs only during favorable weather conditions. 

Step #4: Mixing of All Products 

Mix all roofing products, including Polyglass products & elastomeric coating, to start the application process. 

Expert Advice: 

Use a ¾-inch corded electric drill to perform a top-tier mixing. Store the mixture in different storage equipment to avoid melting. 

Step #5: Application Process

Use a high-quality paint roller, brush, or airless sprayer to apply the elastomeric coating on the roof. Start at one end of the roof and thoroughly work your way toward the other end. Ensure you’re applying the coating evenly across the entire roof surface since it is common in DIYs to

Expert Advice: 

  1. If your roof is small, use a roller or brush. Moreover, apply steady and even pressure while using a roller or brush. 
  2. Utilize an Airless sprayer for larger roofs. Follow a systematic pattern, such as back-and-forth or side-to-side motion. 

Step #6: Drying and Curing

Wait for 24 to 48 hours to let the elastomeric coating for roof get dry and cured. 

Step #7: Inspect and Touch-Up

Once the coating is fully cured, inspect the roof for any missed spots or areas that may need additional attention. Moreover, these areas should be touched as needed to ensure complete coverage. Also, clean tools and equipment should be used for application promptly with water or a recommended cleaning agent.

By following these steps, you can seamlessly apply the elastomeric coating for roof.
