When you pull off the plastic pull from the solid side so you do not stretch the material. I’ve had it installed for a month and have had no lifting. Also use a paper cutter if you want perfect easy cuts. If your cut is wrong you can recut it on the paper cutter with sticky side up. Dont think a little more is better when butting to an edge. It pushes the product up. Recut it and it will lay down.
If you do end up with a gap you can use appliance white touch up paint. It comes in a tube with brush like white out.
I only say I’m an expert because I’ve done a lot of peel and stick stainless steel paper (super hard).
