Tiling on a Wooden Floor

oddman

I have wooden floor boards in my kitchen/dinner and havebought some polished porcelain tiles for it. It’s a Victorian ground floor flat and can bea bit damp – although I’ve taken steps to rectify that. I’veread loads of stuff online (sometime contradictory) but I’d love someone toadvise whether I’m planning on doing this properly and if poss recommend someproducts:

1. Screw all floorboards down securely.
2. Get 12mm WPB plywood and paint the underside andedges to seal against damp (can anyone advise a product for this?)
3. Glue and Screw the plywood to the floor, leavinga 3-5mm gap between
4. Fill the gap between with silicone sealant
5. Paint the top of the Ply with an acrylic primer (cananyone advise a product?)
6. Tile the floor using a flexible adhesive andgrout (can anyone advise a product or products?)

I’ve only seen the idea of leaving a gap & filling witha sealant once....is this necessary?


Any help, really appreciated. There’s a lot of info out there for tiling butit’s hard to find one source that will give me the full process and whatproducts to buy.

yes
you can use backerboard for the floor
no need to glue or leave a gap
no need
yes
yes get some decent stuff (bagged not tubbed) from the tile shop not the sheds, if they are light coloured tiles get white adhesive.



you will also need sealer for the tiles fila rather than lithofin, one coat before grounting & one after grouting.
