Tiling on Particle Board Floor?

[Dave Holland]

Hi All,

New to the forum. I'm after a bit of advice because you guys seem to be the ones to ask! I'm about to lay ceramic floor tiles in a small bathroom with a particle board floor, I've had a lot of conflicting information as to whether it can or can't be done and whether the subfloor must be changed. I understand the particle board is not an ideal base because of its porosity, can it be sealed or waterproofed? If so what primer/membrane should I be using?

I've tackled a few larger floor tiling jobs on compound floors and the room I'm about to do is small so I'm not overly concerned about changing the sub-floor if this will produce the best result. If so, changed to what, marine ply?

ANY advice would be greatly appreciated.

Thanks!

Dave

I would change it mate and use WPB ply 22 or 25m. Marine ply is also good stuff but very pricey. Or you could overboard it with Hardi board

I would just overboard with Hardi if there's no bounce in the floor.

Thanks Both,

That's a great help and pretty much confirmed what I was thinking. If I use either the cement backer board or ply, do I need any additional waterproofing or do they work well alone and which adhesive should be used?

Thanks again

Why does the floor need to be waterproof?
I would clean up floor, prime with suitable primer & fix Hardi 250 (6mm) with either a slow or fast set SPF adhesive & appropriate screws.

Thanks mate appreciate the advice, it's cleared a lot up

Cheers

I would then use bal single part fast flex and bal wide joint grout with GT1admix..

Hope it's a DIY and your not charging for it!
