Floor tiling (Shhh say nothing it's LVT!) - Tile Advice

[Deleted member 49260]

Hi All (well @Spacey really )

I'm about 90% through my bathroom and happy with the refit so far, and especially so with the wall tiling following advice gleaned from here lurking, albeit this is mostly tile on tile, heaven forbid it's actually brick-bonded, AND with bumpy tiles (I know - but I'm not the boss...)

Next job is now the floor and I've stabilised the 19mm chipboard with lots of screws and noggins, over-boarded with 6mm ply - 150mm centres across the staggered panels with 50mm at the board edges.

My question is (rambling I know) is should the plywood panels be butted tight and then prime/SLC'd or loose fit and gaps filled with skim coat then SLC, for SLC I'm using a smoothing compound of course ;-) my spikey roller arriving tomorrow so I can't put job off much longer! I have a Fein multimaster if I need to detune the butt fit panels to gappy ;-)

If job wasn't a quick refit of an old Aunts house (penthouse red bog anyone?) to then sell to fund her care I would have used a pro - but then I wouldn't have met you lot straight away, as I'd have had 3 quotes and picked the cheapest AND then come here to ask for help ;-)

Few pro's would have over-boarded with 6mm ply. A failure waiting to happen. 6mm Hardie glued & screwed would have been a better choice.

Could be worth popping over to the Flooring Forum where Spacey originated from and currently resides:

I think you will find the minimum overboarding recommended by the likes of karndean is 10 mm

Cheers for that I was going to try Flooring Forum - Flooring Advice Forum | Flooring Forum | The Original Flooring Advice Forum - https://www.flooringadviceforum.com but it just tumbleweed in there...

I know cement boards are definitely not recommended, although once it has SLC on top I'm noture it matters - and is probably overkill for Vinyl?

Not according to the tech docs (which don't like wood full stop!) but I do just have just enough room for another 6mm (really 5.5mm) though I doubt 2x6/5.5 as good as 11/12??

6mm Flooring grade plywood is the minimum requirement for Lvt flooring.
To make the best job prime it (not pva ) then use a quality flex screed which must be 3mm min.
