Chipboard floor

[rj1884]

Thanks for your replies. Andy I was told not to use af200 on chipboard only on ply. I take it you've done this many times before. I'm thinking to be on the safe side I would still over board then ditra. What's your thoughts on this.

As you I would always overboard!cement board is always the best substraight to tile on to. If it's not recommended then I wouldn't use it!
I always make the phone call if I'm unsure?
Hope that helps?
Cheers Andy

A lot of adhesive company's don't recommend priming timber now!so always check with the adhesive manufacturer beforehand 

Intrested in your advice.
always prime my floors usally use granfix adhesive.
Which adhesive manufacturers dont ask chipboard floor to be primed?
Not saying your wrong, just interested.

I don't tile straight onto chipboard! It's to risky
I use Tilemaster adhesive for everything!

Cheers Andy. I've spoken schulter and they said you can ditra over hardie backer. Can I just you all this question for my piece of mind. I mentioned to the customer about putting ditra over the backer board to assist with the movement of the floor as it's a new build and the substrate is chipboard. This option was questioned straight away by the customer who just so happens to be a builder. Am I right in thinking that this would be the best course of action in this scenario or am I being to cautious. I'd rather be cautious then not. There may be an issue with height as the first plumbing fixing has already been done.
Thanks in advance.

I'd be interested to hear everyone's thoughts on this too.. My understanding is that it's unnecessary, but I've been wrong before.. 😉

I was going to comment that its not needed to on the basis that cement board doesn't expand/contract as much as the chipboard would but im guessing that is wrong lol
