I was very sceptacle that the product would work for me. However much to my surprise, this product was incredibly simple to install. Easy to reposition and once pressed to wall it adheres very well. Follow instructions, clean the wall as required, watch the video if necessary. I'd also like to add that when I show this to people they honestly believe they are real tiles that I spent countless hours installing, wrong.... 4 hrs. for the job I did including washing wall and allowing to dry. I've attached an after picture but don't have a before picture however, picture a stained, eggshell white wall prior to installation.
