Need to relay a ceramic tile floor

We laid ceramic tile in a 8'x12' area and put a wood stove in the one corner. We laid the tile over particle board and all the tiles have let loose and are no longer adhered to the floor. We are going to take up the tiles and put down cement board and start all over again.

Question: Can we relay the tiles just as they are, with the adhesive on the backs of the tiles? I do not think we could get the adhesive off of the backs.

Thank you for your time...Donna

first off the particle board has to come up and be replaced with plywood then Cement board.

what type of "adhesive" did you use ?

I hope not the premixed type.

If you in fact have particle board for subflooring/underlayment then it's gotta go. You won't have any better success putting CBU down over particle board. We should probably go back to the start and find out about joist size, spacing and span to see if the joist structure is sturdy enough to support a tile installation.

I would vote "no" for reusing any tile that you can't get the thinset off of. You did use thinset didn't you? It wasn't premixed stuff out of a bucket was it? If it was stuff out of a bucket, you may be able to soak them in a bucket of hot water and scrape the mastic off.

If that doesn't work, I'll always think it should have.

Aside from preparing the floor to recieve new tiles,

Why not just look at buying new tiles, and compare that to the drudgery of cleaning up dried adhesive or thinset covered tiles...?

If it's not a huge amount of tiles, I'd just go buy new .........
and if it is a large amount of tiles, that's still a lot of drudgery ahead.

Stimulate the American Economy, buy tile!

Good luck,,,,

I will combine answers from the 3 posts.

1. The flooring is 16"OC and 2x10s, at least. This is a manufactured home and the frame for the flooring is very beefy.

2. I did use the premixed adhesive that came in a bucket. I got it at Lowes. I tried soaking a small piece in water, but the mastic would not come off.

Now, for a couple more of my questions:

1. We believe that the particle board is the only subflooring and we can not take it up. Can't we just screw plywood right over top of the particle board? Then put the tile on the plywood. We put tile in another house on the floor in a kitchen and put it on plywood. Do we have to have the cement board because of the heat from the wood stove?

2. You all seem to be indicating that we have to get the adhesive off of the tiles. We can not just put another layer of adhesive right on the previous layer?

I really appreciate you taking the time to answer my posts.

Thanks alot...Donna (dreading this job!!!)

1. It probably is your only floor. If you install ply over it, the particle board can still buckle and ruin your floor. You should tear it out. When you do you'll see your joists. Screw your new ply to this to be happier longer. You need the CBU to adhere the tile to. Wood expands and contracts. Cement: not as much.Yes it also gives more protection from the stove too.
2.Either remove the adhesive or even better, buy new tile. That adhesive came from a bucket. It's not proper thinset. You'll have way too many problems if you use glue like that. Get real thinset. It comes as a powder in a bag.
