Floor levelling question

[bluebaron]

hi all

I've removed three layers of floor buildup in exsisting house and plan on blending into new extension. My new screed will end up at the correct level but the old floor is now very chewed up. It has levels up and down 30-50mm.

How's would I approach sorting this out? What is the limits for floor levelling compound?

Thanks

You can use Tilemaster level flex. Goes up to 50mm
Or use standard Screeding compounds with granno
