sub-floor lip

that doesn't look like 30mm centres to me! lol

30mm centres?? You would use a box of 500 screws for one sheet!!

You might be alright with 35mm centres

sorry?

the ply is screwed at 150mm - ( apart from where pipes are below )

regarding shims - would that work good enough for tiles?
rather than the pennys ill just grab a bag of packers from the shop. i think its like £3 for mixed bag of 1mm-10mm packers

Was only having a laugh.
I would lift that sheet & put shims in & bring it up to the height of the other boards.
A lot cheaper than flinging slc at it.

that's alright lol.

such a straightforward and obvious solution that I didnt even think of it! :lol:

is there an "acceptable" lip in subfloors? say 1mm between adjoining boards?

 

[Stef]

Depends on what size trowel?
I wouldn't bother about 1mm, tiled to a lot worse than that.

150mm centres is more than adequate.
At 30mm centres you would use 3240 screws,a bit much if my calculations are correct.

20mm or 200mm? 20mm centres would be a LOT more than 200 screws lol!
