Levelling compound gone bad

Hi there

Our tiny kitchen has predominantly a wooden floor with a small patch of concrete just in front of where kitchen cabinets will be.
We had someone put plywood over the wood and then levelling compound over the concrete with the idea of having the two surfaces be same height.
Unfortunately the levelling compound was a tiny bit off and the fitter tried applying a second layer by scraping it on (I know). Result: slight undulation. I've sanded it but still not perfectly flat. We're talking small amounts.

We're thinking of having an Amtico click smart floating floor and I am weighing up the options:

- Take a hammer/chisel to the compound and start again (annoying prospect)
- Keep sanding (may be a waste of time)
- Pay a professional to come in and give his opinion on best practice.

Anyone had experience with this kind of thing? Any thoughts greatly appreciated.

Can't you skim it?
If the ripples are tiny, the underlay will take care of them.

How far out is it?

The way you describe it doesn't appear to be a million miles from being ok

What would you skim it with?

It's not a million miles from being o.k for sure.
Difficult to say for certain how far out it is. I have some sample Amtico LVT with underlay attached. When laying them over the concrete area there's slight movement/wonkiness in some places. Perhaps 1mm.

1 mm won't make any difference.
Old properties have dips of a lot more than that.
Anyhow, if you want to skim the ripples, anything will do.
If you have some levelling compound left over, mix it wet and use a float to smooth it.

Something like FBall Microcoat Stopgap 500 Featheredge is perfect for skimming small imperfections.
