Floor not level

[F]

I've just spent the last couple of days laying a laminate floor.

I assumed the concrete floor onto which it was laid was level but now the laminate is down and I can stand back it's clear it's not. The last

600mm drops by 10 - 20mm.

I've got someone coming in on Wednesday to mitre and fit the worktops. Ideally I would like to level the floor but I'm concerned that any damp screed will damage the laminate which has to go down (admittedly onto a dampproof underlay) before the cabinets and then the worktops can be installed.

Anyone able to offer a view on how to proceed? I could simply ignore the slope and just raise the back legs of the units. But Management is aware of the situation...

Will your managements guests be looking under the cabinets?

I've already asked that question. The answer was something like 'No, but I know it's there...'.

Slope sounds too big to ignore, especially if management has spotted it.

Self levelling screed dries pretty quickly, something like 24hrs - would that help?

Secondly, I wonder if a hardener added to a powdered self levelling screed or even a mortar mix would help - or maybe not.

Always seems worse once she has!

I had used some to remove a hollow and it took a couple of days to dry - I ended up pointing the exhaust from the Earlex vacuum on it for an hour!

Unfortunately, when I levelled the 'hollow' I hadn't seen the forest, just a single tree. I wanted to get the job done and didn't have time to stand back and admire my handywork until I was finished. Not!

I've got a couple of sheets of plasterboard in the garage. Would that be too soft to use as packing/filler with some self levelling to get a smooth surface?

You can get floor filler that is ready to be trafficked in an hour or

2, its used in commercial situations. Alternatively you might be able to use some wood strips trimmed and glued to reduce the problem.

I got some of that and have left it for the last 20 hours. Hopefully there's not enough moisture left in it to affect the laminate tiles which have got to go down today on top of some Quickstep Combifloor damp proof underlay...
