Hello uk.d-i-y
I've Googled quite a few old levelling compound posts in this group, but none are exactly the same situation.
I've got an asphalt floor which undulates a bit. I want to put a laminate floor down, so I've tried to level it.
First I got it really clean, then covered it with a couple of layers of dilute PVA adhesive which I let dry. I've poured Wickes Levelling Compound over about 15 sq m of it and quickly spread it with a trowel.
(I see now that other posters have recommended against using this on anything except clean, almost flat concrete).
Well, I mixed it to exactly the right dilution, stirred it mechanically till it was very smooth (but not airy) and used it within minutes. Immediately it hit the floor, the suspended grey concretey bit separated from the clear brownish bit. I managed to trowel the grey stuff around a bit, but it's dried to a swirly mess of distinct grey, light brown and white regions (although it is flatter).
My questions:
What did I do wrong, and how can I avoid it next time?
Is there some reagent which will help removing the stuff without harming the asphalt?
Or can I just do the rest of the room, put down the laminate floor and forget about it?
Many thanks.
