can i put ceramic tile on laun board in kitchen and will it stick ok?
You can do anything. But you should not do this. Use wonder board for tile. Dur Rock. Cement board. Whatever you want to call it. I can tell you 100's of horror stories from people who didn't do this. Your job will look great maybe a year if you don't then the inevitable cracks, shifts and unevenness will appear. You need a firm hard thick solid surface for tile.
It ll stick for awhile but won t last. The total substrate thickness won t support tile. There will be to much deflection and the bond between the tile and luan will come loose from movement. You need a minimum of 1 1/4 total flooring to support tile. Most cases this is 3/4 sub floor and a 1/2 of a cement board or special plywood , properly installed. This come from both the TCA and ATC tile guide hand books. Any questions you can e mail me through my avatar and check my qualifications there. GL
