DicorCS114B-1 Seal-Tite Corner Seal Tape - 1.25" x 50' - RV, Trailer, Motorhome Repair Tape

I used this to repair/reseal the aluminum corner beads on my fiberglass 2016 Gulf Stream Vista Cruiser. The tape is very, very, very sticky and therefore a challenge to work with, but man does it adhere to the fiberglass! Tips: Once you figure out how to peel away the clear plastic film, make sure to maintain at least an inch or so of plastic beyond the tape itself. Try your best to only touch the adhesive with one finger at a time, LOL. I discovered that you can sometimes use the plastic film to hold the tape as you apply it. It's surprisingly thin; thinner than the butyl tape I removed. Use a SHARP utility knife to cut it, starting on the fabric side so the knife doesn't get stuck. Try not to stretch it too much length-wise as you lay it down... easier said than done. I applied it first to the vertical wall surface, which is where I set my guideline (less than 1/4" from the edge of the fiberglass). After applying 2 feet or so, I'd lay the roll on the roof or just stick it to the side of the camper, then go back and fold the tape over the corner onto the roof. Try to stretch a bit as you do this to "pull" the surfaces together. Then I used the side of my utility knife to smooth the back of the tape and "set" it. Take your time and prepare for some frustration. (The prep will take you longer to remove the old butyl and silicone (use mineral spirits and a plastic scraper)). Have already driven through several hard rains and it's working. I've also used it in place of butyl tape under marker lights and when replacing the stove hood exhaust outlet.

Nice material very sticky .Installed on the corners of our trailer and put buytle tape over the top. Worked very nicely.

For anyone who doesn't know, only one side is sticky. The other side is a soft white fabric. So if you're planning on using this for a non-RV project, be aware of this fact. Other than that, it's a nice quality and easy to use butyl tape.

I bought this to seal the corners of my camper as it had extensive water damage from prior owners, not taking care of it. You need to clean the surface very well before applying, and make absolutely sure that where you lay this stuff is where you wanted to stay, because does not peel up! It will stick on and ruin the piece that you are using. If it’s not super hot outside, maybe go over it with a heat gun just to make sure it is sticking well because it sticks best in warm weather or in the sun.

This product came in a timely manner. It worked great on sealing the camper’s seams.

We really liked this product. It was very easy to apply and the adhesion was excellent. We have a 15 year old trailer and we decided it would be good to seal the corner seams on both front edges. We just noticed a small leak on a front corner on the floor and we believe the leak began in a front roof top corner and ran down the front edge. We resealed the front roof edges with lap sealant but also decided to do the front vertical corner edges too. When we removed the vinyl trim we noticed the four top screws on the metal corner trim on the side with the leak had rust on them. We removed the corner trim pieces, applied the Dicor corner tape, cleaned off the old caulking, added new butyl tape and reattached everything. We have had one rain since then and could not find any evidence of leaking so it seemed the corner tape and new sealant worked well. Thank you, Dicor for an excellent product at a good price. And we have enough tape to do the back two corner edges as well. We watched a YouTube video for additional instructions on how to do it.

Good quality and makes a great waterproof seal. Follow the instructions and the installation is easy

Was skeptical at first but this stuff worked amazingly to seal up the corners on a RV I repaired. Would definitely recommend.

Amazing product works as seen, easy installation and seals up really well!

Love this product. Stuck really well as we put it under the J mould. Was able to fix some gaps with it as it is thin but really strong.

Worked very well. Great adhesive quality. Most difficult part was separating thin clear covering from adhesive layer.

Can't say to much as seems to seal well but only time will tell.

It’s as advertised, it went on easy seems fairly strong! People said it was impossible to remove and once it’s stuck on and rubbed down tight it is but while installed if I stick on one side and didn’t really stick hard I could pull up and move over a bit but once I was done and rubbed it down good to stick it, well it ain’t coming off.
