Ideal 31-605 Duct Seal Compound, 5 lbs Dark Gray Putty

Using the Ideal 31-605 duct seal compound is easy. First, make sure the area around junction boxes, flashings, or service entrances is clean and dry. Then, take the 5 - pound dark gray putty and apply it to the area you want to seal. Since it's permanently soft, you can mold it easily to fit the shape. Right after applying, you can paint over it as it's non - toxic. When it comes to maintenance, there's not much to worry about. It won't harm other plastic materials or corrode metals, so it should last a long time. Just keep it away from extremely high temperatures. That's it! You're all set to have a well - sealed area.
