If you plan on using them on the wall, they are slightly heavier than vinyl planks intended for walls only, and will eventually fall. I reinforced with 3M super adhesive spray and several stubborn spots still fell. So, I brad nailed them, which did the trick. Im sure they would have stuck fine if we used them on the floor. We had ran electrical for the TV and smart switches. I hate mudding and sanding, so I decided on an accent wall to cover the drywall patching.  It was more work than I had anticipated, but love the end result.
