Sub floor

[joec1985]

I'm getting some Lino fitted in my bathroom but the floorboards are uneven and not adequate. I've been told I need plywood fitted but to be honest it's going to cost to much from what I've been quoted. Saw this product and was wondering if it would be suitable for Lino and if anyone has used it for the same purpose? Thanks.

Maybe but at 18 quid you can get some hardboard yourself or thin ply and cut to size and tack it down as necessary. Then you'll have enough left over for a pint.
That stuff is more for cushioning than covering holes and gaps. If you have a slop or differing heights even overlaying it won't sort it completely.

Cheers. The room is 9ft by 7ft 8 I've been getting quotes ranging from £100-£200 I wouldn't even know how much I'd need to buy

Standard sheet is 8 foot by 4 so just over 2 sheets. If you go to wickes or b&q they'd cut it for you to get it in your car.

That's a laminate underlay. You can't use that for vinyl. Put 6mm plywood down. Costs about £15 per 3m2 sheet

You may find the 4x2 sheets easier to handle, and you'll want 20mm ring shank nails to fit the boards down with. Nailt at every 6" in a square pattern, and that'll hold the boards down nicely. Lino is normally glued down at the edges, but the screwfix boards you were looling at can't be fixed down, and wouldn't take the glue either.

Ok thanks folks very helpful as always!

Sorry for raking up an old thread. Would 4mm be to thin?

Well, hardboard is 3mm, but I suspect 4mm plywood may be too thin. Hardboard is more flexible, so unless you've got serious problems with the floor, I'd go with the harboard, but if there is problems with the floor, then yu'll need at least 6mm ply.

4mm ply is very suitable for covering the gaps between floorboards, which would otherwise cause wear lines on the vinyl or other floor covering.

It does not sag or bubble like hardboard can

when cutting it to fit, make all your cuts round the outside of the room, so that the factory edges, which will be perfectly true, straight and square, butt together with no visible seam.

You can use giant staples or carpet tacks. It won't need many.

You can, but the ring shank nails won't come loose.

Thanks the room is 9ft by 7ft 8 how many 8x4 sheets would I need do you reckon? Thanks.

 

[Doggit]

Are yu going to take the toilet and wash basin out; you'll get a much better job if you do.

In theory, you only need 2 sheets, but it'll make for a bit of a patchwork job, and you're going to end up cutting the sheets into smaller sections to get them to fit, if you don't take the bits out first. Looking at the room, I'd still go for 4x2 hardboard.

 

[joec1985]

Went to b and q today and they do 3.5mm hardboard 8x4 they can cut them down. I'm moving the toilet basin and sink yes. Just wondering what I would use to attach them to the floorboards?

20mm ringshank nails. They have serations around them tat stop them creeping out. Tacks etc will come lose over time. Nail them every 6 to 8 inches in a sqaure grid pattern, and you'll be fine. There's school of though which says wet them first, but I never have.
