Mobile Home Flex Mend Underbelly Repair Tape 4" (inch wide) x 108' (feet long) This Is a Smaller 36 Yard Roll Than the 180' Roll Listed Separately Finally - a neat, fast permanent and inexpensive way to mend holes, cuts, and tears in most mobile home bottom closure materials is at hand. Flex-Mend is a time tested mending product that matches the appearance and texture of bottom board closure materials used by most manufacturers in the mobile home industry today. Flex-Mend is a woven polyethylene film currently meeting all requirements for use as bottom board by the mobile home industry. It has been solid-coated with specially formulated, high tech adhesive, and has an easily removed release liner. It goes on like a band-aid! Polyethylene underbelly is a black tarp-like material. This material is found on the bottom of most manufactured homes built since the 80's. If your underbelly is more rigid like a board use a different type of repair like Eternabond. Very few tapes will stick to the underneath material of a mobile home, much less stick permanently. Duct tape will only work for a short period of time. If you want to eliminate taping the rips and tears in your underbelly over and over again, use Flex-Mend tape. When placed over holes and tears, the entire Flex-Mend patch bonds tightly to the bottom closure material PERMANENTLY. Immediately following application, flex-mend patches are almost impossible to remove without destroying the patch and/or the surface to which it is bonded. During the next few hours, adhesion becomes stronger and stronger. Repair holes, cuts and tears resulting from plumbing repairs, weak seams and damage by cats and other animals quickly, neatly and permanently. Flex-Mend is also waterproof and unaffected by cold and can be applied in below-freezing temperatures and will hold regardless of the season.
