Screeded floor v dusty advice on laying wooden floor

[worz]

Hi all,

I have a screeded floor in my newish extention (1 year old) and am at last ready to actually plan laying the flooring.

The screed is very dusty will I need to put some sort of pva across the whole thing before laying the floor? Obviously after thouroughly hoovering it.

Also the screed falls away towards the patio doors, should i just fill these areas with a leveling compound ?

I was thinking of trying to lay 15mm engineered using the sika liquid batton method, thinking this would be a better job than my other option which was going to be floating the whole lot on an underlay?

Any advice welcome

As usual thanks in advance.

How big is the area? How much does the floor slope towards the doors?

I'd be inclined to use levelling compound over the whole area to give a perfect finish to work to.

The whole area is about 33 sqm and it slopes away to a maximum of about 8mm on one door and 5 mm on another. The slope is approx 50 cm length ways.
