Tiling on bowed/warped T&G

Not ideal, but as it's for you and not a paying customer i'd say at 400c/c screwed down every 150mm you'd probably be ok.
Make sure a flexible ady is used.

Slightly confused over nggin spacing.

If I go for screwing 18mm wpb down every 150mm along the joists do I also need to fit noggins across the joists so that the noggins are 150mm apart (centres). That would allow me to screw along the noggins every 150mm as well so I can see it makes sense - just sounds like a lot of noggins.

Up for doing a thorough job so don't mind that many noggins - just want to make sure before going too far.

Advice welcome please.

Better to over do things than skimp.

300mm spacing is BS standard...overboarding an existing substrate requires closer fixings but not direct onto joists....22mm ply would be my option and then keraquick with latex plus.....

Cheers for the advice. I'm going straight onto the joists and not over the existing boards - they are too far gone.

So the upshot is I put a noggin in every 300 mm if I then screw 22mm ply on top, with the screws going in every 300 mm.

As I said earlier - all advice welcome - thank you.

Might lift the level of the floor too much!

tile on the floorboards then, you will be lifting the tiles up instead :lol:
