ADHES Butyl Tape Waterproof Tape Aluminum Foil Tape Sealan Tape 50mm x 5m(2inch x 5m), for RV Repair, Window, Silicone, Boat and Pipe Sealing, Glass & EDPM Rubber Roof Patching, Silver

Had a leak in my downpipe & tried this tape as a temporary measure. Worked a treat! Really good grip, very strong & I'll definitely use it again (well, I have) & would definitely recommend this product!

The tape worked perfectly for sealing and repairs initially. However, after some time, the glue started shifting to one side, making continued use a bit tricky.

Does a great job, really works perfectly. Glad I went for this.

this does the job properly, its very sticky and easy to use.

Was really good for the first half of the roll, but not sticky on last half of roll.Would usually have rated lower but customer service excellent and refund offered without fuss. I have put down to dodgy roll in batch - these things happen!I will buy again as product good and works well.

Some dubious claims for this tape. Cannot seal if wet, loses its tackiness immediately. Parts need to be dry before application. I wouldn’t describe this as an adhesive tape, more of a mastic tape. The “adhesive” does not seem to cure over time. It is very tacky and sticks well, but not particularly high strength. Expect to see some creep under shear loading, particularly as it doesn’t cure. The tape does have a good thick layer of mastic, and the backing seems OK. Most useful if able to be applied to surfaces that are not too complex or contoured. Would be a better tape if it cured. As it is it’s more like chewing gum backed tape!Update after 4 months use: it’s clear the gum “adhesive” on this tape is VERY weak in shear. If anything pulls on the tape from the side it slides off after a few days. Even flex in the tape itself will make it slide. Very difficult to trust this tape. Seems great when you first stick it, but pretty poor a few days later. I’m left with the impression that the tape is being oversold. The only way I could get it to work was to stick gaffer tape over it to hold it in position. Reduced the rating to one star

Easy to use, and so far appears to be adhering well. Have only used so far for small patching jobs.As an aside, wear gloves when using. The gum is hard to get of your hands.

Brilliant tape
