Lino on hardboard with underlay

[rjm2k]

Water damage to some click laminate kitchen tiles so I'm replacing with sheet vinyl ontop of Hb. The floor has an underlay which is was going to take off but I'm wondering if it's worth leaving and screwing the hb on top. Would that be worthwhile or a bad idea?

Thanks

Really bad idea! remove all underlays and fix the smoothing product directly to the floor.

Are you fitting lino (linoleum) or sheet Vinyl? or LVT (Luxury Vinyl Tiles)?

Sheet Vinyl should be laid onto pre-wet 4mm Hardboard which is usually pinned to the subfloor, it may require some perimeter fixing with anti-plas tape or spray adhesive suitable for vinyl flooring but should not be fully stuck down.

Lino or LVT will need to be fitted to 6mm Ply which needs to be screwed down every 3-4 inches and then a microcoat or feather edge applied to the gaps between the planks and also to the counter sunk screw heads, before the Lino or LVT is glued down in place.

Lino (Linoleum) is incredibly hard to fit and a pro job really.

LVT is doable DIY if you are competent at flooring preparation and experienced in doing this type of install.

Thanks, sheet vinyl, I don't want click tiles again, they hid a leaking dishwasher which is why I need to do something as water got under and spread without it being obvious

Sounds like Sheet Vinyl is what you are looking for, as said, Lino (Linoleum) is a very specialised product, Marmoleum is the brand name that it is sold under in the UK but its a very specialised product and fitting procedure.

So assuming you are looking at sheet vinyl, remove all underlays etc, then assuming its a wood based subfloor, level with 4mm pre-wet Hardboard and looselay your sheet vinyl over this, you can finish the edges with silicone sealant to seal it off and disguise cut marks etc.

Thanks , I'm looking to use atmospheric conditioning as don't have the space to wet and store flat to condition unless I can do that as they go down and leave to settle before pinning into place?

You can buy the hardboard pre-wet and ready to go.

Not from the places I can get to and small sizes due to lack of van

You buy it in 4’ x 2’ sheets.

I've got 6x2 from Wickes, the more trade type places like jewson only do bigger sheets from my enquiries. Thanks anyway

moot point anyway for now, it turns out the chipboard underneath has gone spongy so will look to replace, fortunatly it's only a 6sqm area , probably with ply as this is becoming a frequent thing in different rooms

cheers

If I replace the subfloor with either t&g boards or ply, do I really need the hardboard on top?

Thanks

If the finished surface is flat and level, you can lay the vinyl straight to it.
