Hi Guy's,
This is my first post on your great site. I'm laying 333mm Ceramic Tiles on to bathroom floorboards, approx 4.5 sqm. I heard people say with a flexible adhesive you can tile directly onto floorboards,if secure!
If i "Ply-out" it will produce a step up to the bathroom and I wondered what the minimum ply gauge I could use would be? is 9mm aceptable?
The materials I have purchased are; Bal Single Part Flexible Adhesive, Bal Bond, Tilemaster Flexible Wide Joint Grout for Ceramic Tiles.
Can anyone assure me before I commence, just repairing some boards and removing Bidet and Toilet.
Thanks,
Pete
