Plywood base query

Postby soblue2001 » Thu Jul 19, 2007 6:40 pm


hope this isnt a duplicate post, but i have the following query.

Ive read in many places that before laying large travertine tiles on my bathroom floor, I should lay a plywood base of probably 18 mill as opposed to 12 mill. This though would considerably raise the height of the floor from the hall carpet, therfore anybody walking into the bathroom would probably trip up.

Obviously im concerned more for my large travertine tiles here!

Anyway, is there any possibility to lift up the existing floorboards and lay large sheets of 18 mill ply directly onto the floor joists?

Any advice appreciated.

Simply Build It

really speaking you should line the room with 18mm ply as you have been told.
However if your floor boards are rock solid and there is no give in them at all you can buy ultra flexible adhesives to go iver floorboards.
I would probably line with 18mm ply, but of course it is up to you.

Thanks for the reply Martin.

Not too sure how to proceed. The boards are actually 26 mm and are pretty chopped up.

I think I'll lift them and put 20 plus ply down with flexible adhesive.

All this DIY is doing my head in!
