Tiling over glass tiles & hardboard? - TilersForums.com

[banimeuk]

Re-tiling batchroom/shower. I've got some glass tiles I'd ideally like to avoid ripping off, so I've got some tile-on-tiles adhesive. All great.
Problem is, I'd like to extend the area I'm tiling past where the existing tiles finish. Can I put up some hardboard (3mm hardboard is just the right thickness) over most of the additional area?
Will all the tiles just fall off?!
Should I prepare the hardboard surface with anything?
Rough or smooth side facing the tiles?
Or should I just get the tiles taken off and do it properly..!!!

Thanks for any advice offered!

Wouldn't use hardboard would suggest either remove tiles or build out additional area with plaster.

take the tiles of and do it properly!:yes:
you can come across problems tiling over tile such as the weight that that wall will be holding,you also don't know how secure the previous tiles are!

I'll put the hardboard away. Removing the glass mosaic tiles might be a complete nightmare, so I guess it's build out with plaster or not extend the tiled area.
Thanks for the advice!

Yes - that's a fair point... I reckon the tiles are pretty secure, and the are isn't large (roughly 2.7m2 on the main wall) so I'd hope the weight wouldn't be too much? I might try to start a corner of the mosaic tiles, and see how easily they come off. If they fall off, I definitely need to remove them all! That would leave me without the problem of making tiles that stand 12mm proud of the wall look OK I guess...

Thanks again for your help - really is appreciated!

Well, the tiles are coming off Pretty easily actually! I'll need to do some scraping to get the remaining adhesive and some of the paper backing off, but shouldn't be a problem.
Thanks!

OK, well, I reckon that's about half of them, and some of my fingers are wrapped in masking tape on account of the blisters...
This of course was all the missus idea, and she's just phoned to say she's going for a couple of drinks after work. What's that on my forehead? guM?
It'll make the whole job easier tomorrow though, assuming I can convince these arms to move tomorrow...
