Additional Product Information


The area should be dry and free from debris or other substances before RoofSeal can be applied. Cleaners such as EternaClean can help with this step. Remove the lining as the tape is being applied to reduce the chance of mistakes and to keep the tape from coming into contact with the wrong surface. Pressure should be applied to set up the bonding process and remove any air bubbles. A steel roller provides the best results, although you can use your hand if a roller is not available. It works under a wide range of temperatures, however if the ambient temperature is 40 F to -20 F, the surface should be treated with EternaPrime surface conditioner before application.
