Application Instructions

Proper surface preparation is important to ensure optimal adhesion. To apply, thoroughly clean the surface of dust, oil, dirt, and loose particles with a broom or brush. If there are any loose parts and laps, secure them with nails. Use a trowel to spread, covering the surface about ?” thick. Be sure to smooth down all edges. Trowel onto splits, blisters, and cracks and cover three inches around the affected areas to mend them. Embed the asphalt coated glass fabric into the newly patched area and cover over with a topcoat layer. Use waterless hand cleaner to clean up directly after use.

Recommended For Use With Superior Industries’ #303 Reinforcing Fabric

When repairing larger cracks and crevices, we recommend that you use Sentry Seal 100 in combination with #303 Reinforcing Fabric. #303 Reinforcing Fabric is a specially designed black asphalt saturated fabric that is perfectly suited for strengthening repairs. #303 Reinforcing Fabric is ideal for strengthening repairs on seams, flashings, gutters, cracks, breaks, and blisters. This easy to apply reinforcing material makes long-lasting repairs a cinch. And because #303 Reinforcing Fabric is coated in asphalt, it ensures the best possible cohesion with roof patching materials. Ensure the success of your roof repair and make that needed repair really last by adding in a layer of #303 Reinforcing Fabric. It is available in rolls that are 6 inches wide by 50 feet long.
