thanks mate going to buy some tomorrow..... oh the pva, is it still
worth using that?

Yes.

If you only need a little get some white glue and water it down. Its
near enough.

i've got rid of most of the dust with a hoover, but
there is still some crumbly stuff here and there.

if i need pva should i do that first , then after that do the leveling/
adhesive?


You MUST seal with PVA ,with levelling compound. Otherwise the floor
'grabs' the water and the compound sets crumbly.
