Any areas of damage should be repaired before applying the elastomeric roof coating.

Use Polyglass PolyBrite polyester fabric and mastic to reinforce these repaired areas, as well as around any roof penetrations, curbs, and rooftop equipment.

To address inside corner details:

Apply a generous coat of Polyglass base coat to the inside corner, then embed reinforcing polyester fabric into the corner.

Once the fabric is smoothed into the corner and adhered to the base coat, apply more base coat to seal overlapping pieces of fabric, then cover the fabric area with a saturation coat.

To address outside corner details:

Apply a generous coat of Polyglass base coat to the outside corner, then embed reinforcing polyester fabric over the corner to adhere it, then apply a saturation coat. Then connect the details with an additional 12-inch piece of polyester fabric, applied in the same manner.

To address pipe penetration details:

For pipes, stands, drains, and scuppers that penetrate the roof surface, cut the polyester fabric for the finger flashing so the fabric can cover and overlap the pipe by at least 3 inches.

For the target flashing, cut an opening so the fabric can slide down over the drain pipe. Apply a base coat around the penetration area and work outward horizontally from the penetration point as well as up the pipe. Apply the finger flashing around the pipe, then apply an additional base coating to secure it. Fit the target piece over the pipe and apply a saturation coat.

How To Seal Coat A Roof

Ace Roof Coating Tucson

Any homeowner who has had to replace a roof can attest that it’s an expensive proposition. If you have already made this investment, or if you are hoping to stave it off for a while, consider applying seal coat to the roof for protection. Though generally considered optional on sloped roofs, seal coat is a critical addition to flat roofs, where puddles of water can collect. Seal coat can help prevent standing water from creating leaks, shield the surface against ultraviolet light damage and can improve your homes energy efficiency.


Clear away any old, flaking or loose seal coat with a stiff brush. Brush off any rust present on metal roofs, as well.


Wash the roof thoroughly with an etching cleaner such as trisodium phosphate, or TSP. Unless the manufacturers instructions state otherwise, mix ¼ to ½ cup of TSP into 2 gallons of hot water. If there is mildew on the roof, modify your TSP solution to 1 cup of TSP, 1 quart of bleach and 3 quarts of warm water. The TSP detergent mixture can be applied to the roof using a stiff brush or sprayer. Always wear eye protection when handling TSP.


Rinse the roof thoroughly and allow it to dry.



Check the directions on the seal coat to ensure that current weather conditions comply with the manufacturers recommendations. Some seal coats require a certain temperature range and humidity level for proper curing. If the weather is not with you, wait for a day when it is.

When applied to roofing systems, it forms a highly resilient waterproof top layer that can easily expand and contract with the roof itself as it responds to temperature changes and weather conditions, all without cracking or tearing.

Elastomeric coatings are typically used on roofs, but they can also provide protective coatings for walls and other applications. Many elastomer types are available on the market, but the most common types for roofs are made from acrylic, urethane, or silicone.
