3M™High Strength Large Hole Repair Kit is rated 4.4 out of 5 by 58.
Rated 5 out of 5 by from This is the good stuff. This is by far the best drywall hole repair remedy you can buy. It is the good stuff. The only additional thing needed is a clear dry time range ,after application, to be stated on the container because while “…5x FASTER…” is eye catching and appealing, it is not a common way to state a dry time range. Or maybe add the longer dry time that is being referenced?

Rated 1 out of 5 by from Not like the video. I read the instructions and watched the video. It all started out good applied the backer, then started to apply the spackle. The backer promptly fell in the wall I was able to retrieve it and tried again. This time once the spackle was applied I left it to dry. Checked on it and it had cracked all around the hole and the 2 sided tape is coming off at the top. No I wouldn't reccomend. Very disappointed.

Rated 1 out of 5 by from DO NOT BUY ! Just bought this to patch a hole . Followed the instructions on back of packaging as well as watching the video . The patch plate stuck on at first and then fell into the wall only seconds later. This is not a product you should trust on home repairs. It’s a good idea but 3M did not get it right on this one

Rated 5 out of 5 by from Awesome I’m a female 65+ years old. Never repaired a 5” hole in the wall ever. Followed the directions and the wall looks perfect . Thanks for this invention.

Rated 5 out of 5 by from Works!! Few products perform as advertised. 3M large hole wall repair kit absolutely does. This product repaired a pair of 3 inch holes left in a bathroom wall by a torqued-out curved shower curtain- and one literally cannot see the repair. The compound is superb, easy to work, and sands like a dream. If one follows the directions carefully- it's fail-proof. If I can do it, anyone can. The quality of your repair will only be limited by the paint match you will be able to achieve.

Rated 1 out of 5 by from The continuing saga of the hole in the wall. The repair kit worked well until the spackling compound was applied. The adhesive melted and the patch needed to be reapplied, but first the first coat of spackling had to be removed. It was a pain in the neck.
