Dicor 522TPO-450-1C Seal-Tite RV, Trailer, Motorhome Sealing Repair Tape - 4" x 50' - White

This tape worked perfectly for sealing a tear on my camper roof. Used it to double seal some other areas also

Used on the front cap of a Class C Motorhome, where I discovered after removing a Yamaha decal, that a limb had punctured the fiberglass skin.I had to call DiCor customer service when I couldn’t remove the plastic backing from the adhesive side of patch, and was advised to place patch in refrigerator for 15 minutes to loosen plastic backing!

This really worked well and was extremely easy to use. I also purchased a small hard roller to use with the repair.

The patch I received must have been old because the backing was almost impossible to remove. It should have peeled back easily but the patch stuck to the backing so bad I almost ruined the patch getting the backing off.

A tree branch made a small puncture in our TPO roof. This patch fixed it perfectly. I used a self leveling lap sealant from Dicor as well to cover the edges to make it completely weatherproof. The patch was easy to use. Be sure to clean the area prior to adding the patch and place it exactly where it needs to go the first time. Must be careful to not leave air bubbles.

This is on a 1998 palomino camper with aluminum roof. I cleaned the seams with dish soap and water. Then rubbing alcohol. Then denatured alcohol and then acetone before putting on the roof tape. I would hope that got it clean. It didn't stick the best, better if you caulk the edge. It is not leaking yet though.

Great online instructions. Excellent product. Gave me high confidence that I've got a dependable fix for my the bit of damage to my trailer roof. Just had to wait a long time for our terrible local weather to clear up to remover the temporary fix and get this patch applied. I'm sleeping better at night when it rains now!

Leaks in a RV can drive ya nuts locating them. This product is the best on the market. My husband did all the seams on the roof. Works great sealed all leaks!!! Follow easy directions.

This stuff is great, used to repair some torn TPO roof membrane on the edge of the roof. I put it on in the longest continuous strip I could manage (about 5’ long). It took a lot of careful maneuvering but it went down with minimal wrinkles. Used a rubber roller to roll flat and dicor self levelling sealant to go around the edges. I put it on in early spring and after checking it in the summer it has a few more wrinkles and bumps, probably just from expansion due to the temperature change, I’m not really worried about it. No leaks!

The sealing material is very adhesive and should provide excellent sealing and would get a 5 rating. I hope there is a easier way to get the release tape off the back - I give it a 1 for that. The film is very light and as one might expect stills very well to the adhesive. I had to actually stretch a corner of the patch very aggressively. After many attempts it did come of but holding and pulling on the tape ended up transferring some of the adhesive to the white part of the patch - which is now streaky grey. The patch also need to be cut bigger so when the release tape did dome off the part of the patch that was stretch and destroyed could be cut off

Love this stuff, hate the price. Great for seams or emergency repairs

I cut it in half was too wide for my trailer. Did the job

worked perfect when I used it to repair my rv's roof.
