new tongue n groove - bathroom

[Pac]

hello again, after that last lot of great help i am back for another question if i may.

i have recently replaced the bathroom floor at my daughters. the floor was left for a week to adjust to room temperature and then isntalled with joist vises. they have been cramped very tightly so it will not shrink and leave gaps.

now i have tiled many floor but as this is the 1st time i have done it on new floorboards, i thought i would ask if there was anything i need to be aware of?

do i just ply sheet the floor as normal and screw it down or is there something else i need to do?

any special thickness of ply? or anything to be aware of?

thanks

you can gun screw no issues and get fine thread screws:8:

with the normal drywall gun?

just wasn't sure if 6mm would just snap.

Don't use drywall screws Pac, they are for plasterboard and although sharp they are brittle and can easily snap. I always use interior wood screws.

i already sourced them thanks anyway. it was me having a no hair day not thinking properly. how on earth i expected to cover the floor area with just 2 sheets is beyond me

picked up 8 sheets of Hardibacker from my local tile trade counter. the only weird thing was when i just picked all 8 sheets up in one go, they came running behind me with a trolley but i didn't think it was that heavy rrr:

when you lads say to screw it down and apply SPF. which SPF do you mean? are you talking about a tubed adhesive or a mixed adhesive?

is it alright to use drywall screws (the collated ones i use in my gun)

Hmmm, you a big guy then? 2 sheets is enough for me, 3 at a push!!

erm, normal to me but maybe a little larger than average. i do go to the gym. i'm about 5`11`` and erm..18St

not all fat though, i can bench press just under 22 stone properly without stupid substances because i hate cheaters.

so no, it didn't seem anything untoward to just pick them up but then again, i usually do stupid things like grabbing the missus for a bit of fun and her saying "owe that hurt" :incazzato:

as for the screws, now i am unsure cos one says yes and another says no.

to me, normal screws rust and would react with the adhesive but drywall screws don't. however, the one that said the dry wall screws are brittle is also correct as i have snapped quite a few over the years.
