Laminate Question

[Chrispy6169]

Im looking to put laminate flooring down in my dining room. My problem is that the floor boards are old and arn't very flat. Should i replace with 18mm ply then lay the flooring on top of that or could i just screw all the floor boards down hoping they will pull down flat enought to lay the laminate over the top?

You always want to make sure the original floor is well fixed by screws, and all screw countersunk as should be any existing screws/nails.
depending how far the floor is out, it can be sanded and planed to remove any highs, then a good underlay installed.

If the floor is slightly out, will the underlay help level it?

yes, provided its 4mm fibreboard or sheet, the thin basic foam stuff will be ineffective.

dont forget to lay at 90 degrees to the original

Afternoon guys, ive screwed all the floor boards down but what ive noticed is the floor is sloping up towards where the fireplace used to be! Is there anything that I can do about it?

90 degrees to the the direction of the floorboards? Even if it means laying the boards across the shortest part of the room and across the light?

You can lay it anyway you want as long as you sort out any high spots of the floor boards by sanding the, down and also using a good underlay.

Ok thanks.

Anyone got any suggestions for my previous post about it sloping slightly?

Is the fireplace high?
You could use some leveling compound like level flex which can go over wood.

What I do is plywood the floor then screed it all level. Not cheap though

Yea where the wood meets the concrete it kind of peaks then drops off slightly. My other thought would be lay 4mm hardboard everywhere apart from the higher part to raise it level then lay the underlay over that to hopefully create a level flat surface.

That's will work mate. But use plywood over hardboard.
