Boarding over uneven slate flooring
computid - 7/5/21 at 11:53 PM

Hi all,

I'm a bit new to all of this house decorating and re-building stuff so I thought I'd ask the collective!

I have a slate tiled floor in my kitchen. The slate is uneven and has up to 5mm of change between edges in some places. Its impossible to keep clean and I think it looks awful. The kitchen units were installed over the top of this flooring.

I would like to replace this flooring with modular wooden flooring for both ease of keeping clean, and to brighten up the room. I'm not keen to try and remove the flooring, not least because it runs under the kitchen units which I would like to keep.

I've come across a product called Jackoboard which states it can be installed as flooring over uneven substrates. I'm considering installing this over the top of the slate, and then putting wooden flooring on top of it. Does anybody have any experience of this, or have any other suggestions as to how best to deal with this?

Thanks!

I would be using a floor levelling compound. I can't get a perfect finish with the stuff, but I had a rental with a tiled floor done by the flooring chap, which then had a HD vinyl floor installed. All perfectly flat/smooth.
I would think 5mm is a very big ask of a board, unless very soft and thick.

You need to get the floor completely flat for laminate/wood flooring. I had some issues in a room with a slight uneven floor and I used 1 of these wood look plastic laminates that is meant to deal with that and to be honest it does but only just. Wood is not at all forgiving so I think leveling would be required. If not removing the kitchen make sure after levelling and flooring that you can get plinths in/out and also.appliance aren't trapped in (had this in a rental once).

The floor needs to be flat for laminate flooring otherwise you'll have issues with the joints separating

The other thing is laminate looks nice in a kitchen, but if you ever have a leak in the future it can cause you a real headache

Is the kitchen too big to just take the old tiles up, re-level and then fit the new flooring?

I have just fitted a ceramic tiled floor in place of a slate tiled floor. It was extremely difficult to remove and took most of the day and created so much dust. With hindsight I should have just used self lever over the slate and tiled over that. Problem comes with different levels between rooms. Be careful with any type of wood floor in a kitchen as it is likely to swell and buckle within a short time. Ask me how I know this!! I think a vinyl click floor is the best alternative to tiles in kitchens & bathrooms and I fit lots of these instead.

I would be inclined to leave the floor alone as long as its secure, but possible remove the high spots and fill in and level them

And go epoxy, like the link below, as this is what i am planning on my Parents house soon

You need to go over it with self levelling compound. We lay lots of vinyl click flooring, it's pretty straight forward.

I had a particularly ugly, part-tiled floor in an old pub we own - it had been knocked around so much the floor was all over the place but really solid. Self levelling compound was the answer although it took some time. We now rent it commercially and there are no complaints although it's a funeral directors so I doubt the 'customers' would complain!
