Then I drilled one top hole and installed the drywall anchor

The four predrilled holes are very helpful

We used Gorilla tape to mount it to the wall and put some small nails in the top 2 holes, mostly to cover the holes.

Easy to install, 4 screw holes

I held the sheet up again and installed the one screw and rechecked the other top hole location

I like the predrilled corner holes because the sheet's weight can be held by the screws

Easy to install,has mounting holes in corners to fasten to wall,excellent back splash behind stove,cleans easily,protects wall from heat.
