Flex-Mend:
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. 

Uses:
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.

It has been solid-coated with specially formulated, high tech adhesive, and has an easily removed release liner.

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. We carry a full line of Eternabond if needed. 

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.

Mobile Flex:
Mobile Flex is a special bottom closure, woven from black high density polyethylene and extrusion coated with a continuous layer of low density polyethylene. The material is uniform in quality with no weak spots. Its beach puncture resistance is more than five times the minimum established by HUD! Staple hold out is excellent. Penetrations and cuts will not spread and can be easily patched using our Flex-Mend tape.

MOISTURE- Mobile flex is totally impervious to water. Its strength can not be adversely affected by moisture. Because of its black polyethylene coating, Mobile Flex qualifies as a vapor barrier. Technical report #19757 from Chicago Paper Testing Laboratory, Inc., reports the material to have an average perm rating of 0.037.

DURABILITY- Mobile Flex is produced from a material that has been tested for durability and weatherability. After seven years of continuous, direct exposure to the elements in Arizona, the material retained 70% of its strength. The tapes and coatings are both chemically tested to ensure maximum performance.

FLAMMABILITY- Mobile Flex is classified by Underwriters Laboratories, Inc., as to surface burning characteristics. Mobile Flex tested out to zero flame spread and zero smoke developed. The tests were conducted in accordance with UL Standard Test Method for Surface Burning Characteristics of Building Materials, UL 723.
