Any advice on tiling over old laminate countertops. the countertop is solid, level and i think would make a great structural support, only question is do i need a backerboard or other type of material before i mortar the tile down? Any help would be great. Figured i'd just lay backerboard, screw into teh laminate and tile, didn't know if there was another material besides backerboard that would work, or if i need a membrane as well. thanks.

Dont even bother with the cement board. The screws used to hold it down will puncture and shatter the formica laminate, causing some high spots under the board as well as opening a channel for water migration along the screw to get into the particle board under the laminate.

Clean the top so it has no soap or grease residue, rough it up with sandpaper and use modified thinset to install the tile

that was kind of my original idea, then i had seen people use backerboard... its already a rough surface so sanding a bit and then tiling should work fine... any reason i wouldn't want to use the existing laminate? I've seen several shows where they remove the laminate and instally a 3/4" sub base (did this for my floors), but the laminate they were pulling up had front lips and 3" backsplaces build in, so they couldn't tile over that... but with a nice square edged laminate with no backsplash, i see no reason why i'd want to temove it, its nice and sturdy...

I only reason to not go over it is if the seams have split open, That would indicate water has already gotten into the particle board underneath the laminate and compromised it. Putting thinset mixed with water on there would only be piling on the problem and not really fixing it.

Why is it that American's love to put tile on their countertops? I think it is one of the most unsanitary things you could ever do. Even if sealed, there is no way to ensure that all bacteria and microbes have been cleaned away due to the irregularities in the grout surface. I strongly urge you to reconsider your decision, even if you end up paying more in the long run.

Not too concerned about microbes and bacteria... thanks for the concern though... our space is so irregular that getting laminate or solid countertops would be incredibly cost prohibitive and just wouldn't look good... we're going with tile floor and countertops and backsplash and it should look great... i'll take my chances with the bacteria as i've never had a problem before...
