How to lay Luxury Vinyl Click Flooring and sub floor?

[jasjas17]

Hello

ive had a look at a few videos but ive never actually fitted any of this stuff.
Ive dont plenty of laminate and oak etc and im guessing it goes in quite easy.

here is the stuff

1st is sub floor.
its going in a bathroom over timber floorboards.
id assume 6mm ply overboarded ontop of the floorboards is enough? ive also seen some just suggest hardboard? is 6mm overkill ?

underlay:
whats best to use for this over the ply/hardboard?
the white foam 1mm stuff, the green foam 3mm stuff, or the silver backed 3mm?

Fitting:
After the 1st row is done, on the 2nd row onwards, it seems like you somehow 'click' either the small length or longer length into position and dont have to tap it in? i assume its easy to do but there seems to be different methods?

Expansion gap:
ive seen from 2mm to 5mm listed.


anything else to add?


thanks in advance

1st of all you can't use a Laminate underlay with it.
6mm ply is perfect mate

okay thanks

yes i was thinking of just going with the ply however B&Q said to use an underlay.

A small area 2mm expansion is ok

hi
in bathroom with wall tiles and flooring as above,

would you tile all the walls apart from the bottom row, then lay the vinyl click floor then put in the bottom row of tiles so its ontop of the floor.

or, tile to the floor, then fit the vinyl, leave a 2mm gap and then it would have to be siliconed around the edges really.

If tiles off I'd do last row ontop of the floor. No silicone then. But a thin bead in clear looks good anyway
