Using this duct sealant is easy. First, clean the area around junction boxes, flashings, or service entrances where you want to apply it. Then, take the 1 - pound block of the sealant and mold it to fit the area that needs sealing. Press it firmly in place. You can paint over it immediately after application. As for maintenance, since it's non - toxic and won't corrode metals or affect plastics, you don't need to worry about it causing damage to other materials. Just check the seal periodically to make sure it's still in good condition. If there are any signs of wear or if the seal seems to be coming loose, you can add more sealant as needed.
