High-density fiberboard is the only material thin and flat enough to use as a level surface for my new backsplash. The drywall was ruined slightly when we ripped the old laminate crap off the wall. Can I do glass mosaic tile over hardboard if I glue & screw the hardboard to the drywall? I’m using a modified thinset for the tile, so hopefully it will have good adhesion since hardboard is porous.
Just curious if this is a bad idea or not. There’s are no specialty tile guys to ask in my little town.
I wont recommend it, Since it is so porous it can swell a bit and tile should not be put over any wood that thin.
You d be better off mudding over the holes and ripped up areas in the dry wall. You can even repair some ( depending on the size) with a good thin set. It may take a couple of coats since on bigger rips and tears the thin set will shrink a bit.
EDIT: I saw your 1 st question before this one and saw the pictures you also posted there. I go by my recommendations. Those are not bad fixes, useing a compound or spackle just a quick primer or paint on thoses areas to seal the paper os compound which ever way you decide to go. Easier and cheaper than doing all that area in any kind of board. Plus you run into a fire hazard and possible code violations by having wood that close to electrical. That you can fix by adding box extensions but thats more work and expense.
Any questions you can e amil me through my avatar and check my qualifications there. GL

It’s best to use 1/4" thick cement board. It can go right over the drywall, screwed to the studs. Cement board isn’t expensive, and it’s a moisture barrier. Your backsplash tile will last for years and years over cement board (sometimes called Hardie board). You can buy sheets of it at home centers.
