Glue for backsplash?

Don't use adhesive. Use these:

Doug have you ever used these?

A few problems that might arise

Jim I use the appropriate Liquid Nails and wedge boards between the backsplash and a 2x4 clamped to the counter. Before installing the backsplash I spread silicone caulk along the bottom to keep the water out.

Many times. They're great.

It's not like it *needs* a lot of support; in any event, the depth removed is something like 5/16".

No, you want to leave as little material as possible, actually -- that way, if any water does get between the backsplash and the countertop, there isn't anything there for it it swell up or rot.

I haven't found that to be a problem. Just measure and mark carefully, and it goes together slicker than snot.

Adjust the position of the clips so that they follow the wall, not the countertop. If the wall isn't perfectly straight, the backsplash will conform to the wall.

We had very old formica covered plywood counters and backsplashes. The backsplashes came loose and it appeared the old adhesive was something like hide glue. I put them back, using just a few dabs of silicone caulk. I then used caulk along the top and front to seal them off. Held just fine until we replaced the countertops.

Go for it. Being sparingly on the adhesive, i.e, use "dabs" along the back edge quarter/half dollar size. 3-5 dabs? Mirrors are install on drywall similarly.

Caulk edges after install. If you ever need to remove it, cut the caulk and pry the splash off. Damage would be paper tearing off the paper of the drywall.

How about contact cement
