What modifications do I need to make to install ceramic tile on a formica backsplash? Can I simply "rough-up" the formica with coarse sandpaper? OR Is installing cement board onto the formica the best approach? OR Is there another method better or the only way?

Thanks

if it were my job i would just pull the formica off the wall, it will pull some of the paper off the sheetrock but not enough to damage the surface to where you couldnt install the tile. other than that scuffing it up would be you only other option, id use 60grit and go to town on it, make sure all the dust is off the wall before you start tiling, as for cement board,,,, i wouldnt for this, if it was a tub surround ok but its really not needed

In my province, B.C. that type of installation does not meet building code. I would remove formica, install hardibacker, paint with membrane & use thinset. You will avoid a lot of down the road problems, like bonding on Formica breaking down.

TMflan - Back in the 60's&70's we used to use what was called (SIZE) you painted it on with a brush on formica and then you could paint, hang wall paper, what ever and i never seen anything come loose. I dont know even if they still make it, you used to buy it at lumber yards, paint stores . anythin that always worked real good ,they would stop makeing it ,so you'd have pay larger prices. Check at lowes, home depot if you have them, or a paint store. I think i'll find out the next time I go to lowes:: GOOD LUCK F.B.E. Galvine has a good answer though:::::::
