I agree with Mark.
It also depends on what the Formica is attached to, what adhesive was used, and what shape it’s in now.
Also, does the Formica run down onto a raised portion of the Countertop or all the way down to a Flat countertop. You will be adding about 1/4 to 3/8 of an inch to the thickness of the wall.
If it’s held onto Drywall with Contact Cement, which is the usual way of applying Formica. Say Goodbye to the Drywall. it will come off WITH the Formica.
” the fact that the backsplish covered with the laminate in not problem as long as it is well-bonded to the dry wall, has smooth surface and it is not bucking.”
With all due respect I believe he WANTS to cover the wall with Ceramic Tile.
So, as I see it you have 2 choices. Take it all off, back to the wall studs or strapping, depending on how it was built in the first place. New Drywall, I’d even Prime it before using the Proper Adhesive AND Grout for the new Tile.
Or you MIGHT be able to do it by running a Sander over the Formica, roughing it up, ONLY if it’s FIRMLY Bonded to the sub-strate and using an adhesive such as PL Premium to attach the Tile.
That stuff will Stick Anything To Anything! DO NOT get it on your Skin. I learned the way. Took me about 2 weeks to get it off. Guess I missed the part on the Tube that said ”Can only be removed by Mechanical Means.”
The ONLY way “I” would do it would be to strip it all the way back and new Drywall. BUT! That’s just the way I do “Things”.
The extra work involved, over and above trying to stick it on the Formica wouldn’t be all that much and the Job is done right.
