Cement for ceramic tile.
I wouldn't risk it. It's not recommended to tile over Formica. No matter what adhesive you use, some tiles can still come loose, and the grout may crack, especially at the front edge.
The best course is to tear off the old top and install a solid 3/4-in. plywood underlayment and a layer of tile backer board before tiling. It's less work than it sounds and will ensure a long-lasting tile countertop.
Tile mastiic for adhering tile to Formica (laminate). Thinset will not hole to laminate.
Use dry ice and a scraper to remove the laminate. Then 1/4' "backer board" sold at the home stores over the, now exposed, particle board. Glue it and screw it according to instructions. The problem with leaving the laminate, is you will cause uneven tension, from the new glue, and it will de-laminate from the particle board, causing a mess. Then use Flex Bond tile mortar, and install your tile. Be sure to tap each tile lightly, (like vibrating it) with a rubber mallet, to remove all air bubbles, and "set" the tile. Then grout and finish the tile. Cheers
I have never done this myself, so I would go to Large DIY store and ask an expert in the tiling department what you should use!
Spread a small amount of thinset mortar onto the Formica in the bottom center of the backsplash. Use a trowel to apply the thinset; once it's on the wall, comb through it with the notches until the mortar is an even depth.
