Ok so I LOVE these. They’re very shiny and appear like polished glass, but have a vinyl, almost jelly texture when touched. They clean easily, they’re DIY, and they transformed my space.Some helpful tips:- I used a peel-and-stick wallpaper paste spray to assist with repositioning while I worked. It was very helpful as someone used to traditional wallpaper to be able to “slide” them on the wall.- Probably obvious but prep your wall. Clean, dry, smoothed, and LINED with a level. Don’t imagine you can just line up the joints and it’s gonna end up level down the line ?- Use a wallpaper roller or seam roller for maximum adhesion- Plan to trim in over the ends or butt it directly to a 90 degree surface. They have texture - each shell protrudes. So when cut, you’ll have a scalloped edge where it goes flat-1/8 inch thick-flat etc.. On sides where it touched the wall, it looks fine. On the top and bottom, I placed behind the baseboard and added a chair-rail trim over it to encase the edges and hopefully prevent any future peeling.- I placed out my whole pattern on the floor before I started to stagger the start of each row and avoid the repeated pattern showing up as much as possible.It took me several hours working alone to do a half wall but I’m meticulous and probably took twice as long as some could do it in.Overall love this product and have gotten SO many compliments on my “mermaid tile.”
