Kleiber Canvas Style Self-Adhesive Waterproof Nylon Repair 2 Patches (10cmx12cm Each) -Light Grey, 12 x 10 Centimeters

The spars of my garden umbrella, wore through the fabric due to some violent winds. These pieces of stuff easily helped plug the holes and umbrella is as good as knew.

ok for tent repair but did not stickvery well to the gazebo cover

Awesome - does what it is supposed to do. Just use it on correct material. I used it to fix military heavy duty nylon rucksack and it worked perfectly. I was using Gorilla tape but that started to peel after a couple of days. Worked so well that i bought more. Not sure how well it would would on other materials as Gorilla tape has worked well on other stuff but not on heavy duty nylon.

Used to cover a small tear in a patio table cover. Seemed good but after a couple of weeks the edges began to lift. Not adhesive eniugh.

Waste of money. Initially they look good, easy to use and stick down firmly to clean canvas but started lifting after a couple of days then one fell off altogether.Did try again with fresh patches and re-cleaned the canvas that was damaged...same result again.This was on a boat canvas so may work better on less exposed materials.

A number of small holes had appeared in the canvas roof of my gazebo. Most were tiny but wanted to patch them before they got larger. Early days, but the patches seem to stick well. Each patch can easily be cut into c.8 patches ideal size for these small holes. Attached one on inside and outside of the hole (see pic).

Really does what it says and water tight

Very pleased with purchase
