## Overview

Flex-Mend Mobile Home Flex Mend Underbelly Repair Tape is a 6-inch wide by 108-foot long polyethylene film tape designed specifically for permanent repairs of holes, cuts, and tears in mobile home underbelly materials.

Trusted by the mobile home industry, it offers a neat, durable, and weatherproof solution that eliminates the need for repeated patching.

## Description

Mobile Home Flex Mend Underbelly Repair Tape 6" (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.

Review: Sticks like CRAZY!!! - Had to repair damage on my tiny-home. Had several tears from the idiot who moved it. Because of that mice got in. Got the underbelly stapled back in then taped the seams with this. Make sure you have it where you want it direction-wise cause it STICKS. You get one, repeat ONE chance with this stuff. Mess up a little? Just apply some more. THIS. STUFF. WORKS!
Review: Works great - I used vinegar and water in a spray bottle and paper towels to clean the area around the tears and this stuff worked really well.

## Questions & Answers

**Q: Would this be a good choice to adhere a plastic repair piece to the paper type underbelly of a mobile home?**
A: That is what it is designed for---just have to be certain you do not try to adhere it to the old "buffalo board" type underbelly (does not stick as well to that material). We advise you utilize the non adhesive flex mend for the patch but the adhesive will adhere to most plastics.

**Q: Floor is tore up in mobile home---can we repair on the inside or does if have to be on the outside of the hole/tear??**
A: From outside

**Q: Would this be a good choice to repair a crack in our black water tank in our RV?**
A: No.. it will not fix your crack. It is only designed to mend holes in the plastic bellyboard under a manufactured home.

**Q: What is the difference between fm6108t and fm600t?**
A: 6108 is 6" wide x 108' long
600 is 6" wide x 180' long (72' longer roll)

### ⭐⭐⭐⭐⭐ This stuff sticks great
*by J***R on November 6, 2022*

Excellent adhesion, way better than the best of any brand of duct tape , it is thin , admit I was a bit concerned at first , but this is the right stuff for a professional looking job , sticks extremely well , easy to reposition at first , ( but once you rub it into place its permanent ) , which is exactly what you want ! , adheres to dirty or wet plastic , just wipe plastic off with a rag or gloved hand for best result , no need to get crazy trying to clean perfectly
