What is an Elastomeric Roof Coating?
Most types of elastomeric roof coating are classified as having both weatherproof and waterproof properties. Elastomeric roof sealers are typically polymeric products, which create a seal when they are applied to a roof. They are effective in sealing roof leaks and preventing existing damage from worsening. Since they are durable and versatile in their abilities, they can be applied to the roof during any season. The components form a strong bond, which means that the finished product forms a type of membrane across the roof. Since roofs usually have drains, pipes or other protruding pieces, it is important to spray around them. When the coating goes around these objects, it becomes one surface for maximum durability and water resistance.

How to Apply Elastomeric Roof Coating Step by Step
If you want to extend the life of your roof, then roof coating is a must. Roof coatings can reduce heat transfer, thermal shock, and leaks. You can use roof coatings to benefit nearly any kind of roofing, and when the original coating wears away, you can recoat the roof to extend its life.
Step 1: Choose the Right Roof Coating Products
First of all, you need to use the right roof coating product for your style of roof. It’s easier to treat sloped roofs that don’t have drainage issues, as any reflective white roof coating will work. Flat roofs and roofs with drainage problems require more attention to prevent standing water and moisture from becoming a problem.
Step 2: Wash the Entire Roof Surface
Before you worry about how to apply elastomeric roof coating, you’ll need to clean the roof thoroughly. First, remove all debris from the surface. Use a sprayer or a pressure washer for the cleaning, taking care not to disturb the roof membrane and lap seams. After you clean the roof, remove any loose materials.
Step 3: Repair Any Damage
You can fix some kinds of damage, such as minor leaks, when you coat the roof. However, it is better to go ahead and make repairs before you apply the coating. Coating over damage can make your coating wear out faster, making the coating only a quick fix.
Step 4: Check the Weather Forecast
You will want to reserve at least two full days for the roof coating process. Ideally, you should coat your roof when you are expecting moderate, dry, and sunny weather. Temperature extremes that cause frost or dew can interfere with your coating.
Step 5: Apply Polyester Membrane and Patching Compound
Tietex polyester membranes are 100% polyester, stitch-bonded fabrics that do not rely on adhesives. These membranes are very strong and help to reinforce roof membranes while providing water protection. The Tietex polyester membranes come in rolls, and you should place them over large cracks, joints, and seams along the roof.
Step 6: Waterproof Porous Surfaces
If you have any surfaces that are porous or that have not been previously treated with a waterproofing agent, you should treat them with an emulsion, such as Elastomeric Emulsion, or a primer, depending on the roofing material. You can apply the waterproofing agent with a roller, brush, or spray equipment.
