green chipboard floor help

[The Legend; Phil Hobson RIP]

Hi Andy, how thick is the quartz? CI matting is 3mm laid with 3mm/4mm notched trowel so if you allow 1mm/ 2mm under the mat, and 3mm on top for tile bed, plus the tile thickness. I must add to the above comments chip-board is bad news for tile installations:yikes: sorry

thanks Rich, i was wondering if it would have been more with fixing the matting and then the tiles, 3mm or even 5mm in total would be great so sounds ideal, thanks Andy

thanks Phil , thats great, the tiles are 12mm , i have 20mm under the bi fold doors to the seal so will work out ideal, all the best, Andy

the grey fella in Phils post looked like me when i looked at the price of the matting

Andy we have Dural as sponsers on the forum, they may be able to cut a deal. Price tends to go off volume, if you have 40m2 to do a 30m2 roll and a 10m2 roll. Give them a call. Better to get it right at the begining imo, good luck

I'd be thinking of removing the chipboard and tiling onto the concrete, maybe using something like weber floor flex to build up the concrete to desired height.

thanks doug , but unfortunatly i have 90mm insulation with 90mm x45 joist screwed down to the concrete ,

Is there any chance of replacing the chipboard with ply?

 

[andypar]

not really rich , i think i will sand the chipboard a bit and make a key and seal it ,then try a test area, use the matting and hope, now it is whether to tile under the kitchen units or not hmm, i was going to, but now am wondering if that would be such a good idea.
