Black Waterproof Patch & Seal Tape

Great product as usual. It gets the job done. But just a small note, when you try to use it for the first time, take your time to open the seal tape. It's glued tightly and easy to mess up the very first part of the tape.

This waterproof tape is perfect for sealing in many cases. I recently used it when installing snow cleats on a metal roof. I used it to seal the base of my garage walls to concrete preventing water infiltration . Very good adhesion and awesome waterproofing tape!

This is a great product , very sticky , however if you have a leak with pressure , it will not hold , it blows off really easy and breaks ..I had a very small leak in my sprinkler water pump , and I had to put clamps around it in order to hold .

Needed to repair my basement walkout drainage where the builder did horrible job and water was going into many large gaps around the drainage pipe versus into the drainage pipe. I used this to seal a ton of gaps and cracks and worked awesome! now the water goes where it is suppose to. I used AI to recommend product off amazon after uploading to AI a photo of the damage and this is what it recommended.

Excellent tape! The adhesive is strong but not too difficult to work with. It’s a little funny identifying the adhesive side since it’s not transparent but it’s easy to figure out. The quality is excellent and it feels like it will last for a very long time once applied. I’ve been using it for patchwork and haven’t had any complaints. Depending on the surface, it hasn’t been too difficult to remove and reapply on surfaces that are strong and it hasn’t left any residue yet that I have noticed. This really feels like it’ll work very well for sealing up my cable connections temporarily in light rain.

I had a broken pipe in a two door freezer. When it would defrost the water would run out and then refreeze on the bottom, or anything I had stored inside. Eventually the problem caused a censor to trip and the freezer shut itself down. I got this tape to see if I could patch up the problem without having to pay a tech a small fortune. It worked great, the pipe no longer leaks and the tape is holding up in sub zero weather. I'll see how it holds up over a long period of time but so far so good.

There used to be a different tape made by this company that was fairly thin but worked much better that I cannot find anymore so I got this instead. This product was overall pretty mediocre as far as doing what it says it does. I tried it on a water pipe that had cracked during the winter and it did slow the leak but did not stop it. It was still enough of a leak that the pipe just had to be replaced. When I tried on an airbed type inflatable it worked okay, as in I had to refill the air only daily but it was still useable despite the leak. There was flocking on the airbed I had to get rid of first for it to work. A couple pointers if this is your intended use: 1. Make sure the piece you are using overlaps the leak by at least an inch in every direction. Kind of common sense but I had only about a half inch the first try and it was not working once any weight was applied to mattress. 2. Make sure item is completely empty of all air and repair area lays good and flat. Use something bigger than the repair area that is smooth and flat both under and as a weight on top of repair. After you place the tape put a heavy weight on top to help apply pressure and seat the tape. Doesn’t work well with just hand pressure, I had to leave the weight on for a few hours before it was stuck down well enough. The adhesive isn’t great but works okay after the time left sitting weighted down. Still peels off easier than I’d like no matter how long it is on there. I might try to seal edges of the tape with some kind of glue to improve performance but really shouldn’t have to if manufacturer description is correct. Overall I’m disappointed in this product, it just doesn’t seem to be what they claim in my opinion. Of course real world application and use in a lab setting where originally tested will not be the same as with anything. Fine for use in a pinch. I’m keeping in emergency toolbox as it does have some useful qualities.

I bought this over a year ago. Originally bought it for a blow up pool and yes it did stop the leak from the hole that I covered with it. But we all know inflatable pools suck and it got several more holes very quickly. Well my kids sprinkler pad recently broke open. And I used this tape and to say the least I am impressed. I have attached a photo it is holding up really well.

駐車場の上に敷いた防水シートに亀裂が入り水漏れが発生してので購入しました。自前に亀裂周りの汚れを落としてからテープを貼れば強力に密着し、使用してから1年になりますが特に問題は発生していません。おすすめです。

This stuff works great. I have used it to waterproof truck windows, seal fabric on my ice tent and stop leaks on my aluminum boat. Once on- it is good on all weather. I have purchased over a dozen rolls- best stuff. Once on- it stays put.

I bought this to patch a hole in my pool liner. It's a half inch hole, about 6 ft under water. It's holding perfectly and I can barely see the patch. Remember to peel the protective coating from the tape before you apply it. It doesn't feel very sticky when you first touch it with your finger, but it adheres to smooth surfaces quickly, even under water.

Rubbish. Not working under water nor outside water when try to patch a leak on the above water Bestway pool. Lots money list R375😡😡😡😡😡

Used it for above ground pool (Bestway). Didn’t have to drain the pool. 2 weeks in and still no leaks!
