Like many other people, I want to lay a wood floor (engineered board) over a concrete slab. For various reasons, the slab has been screeded, but the work was not done very well and the screed is not perfectly flat. "Self-levelling compound" I hear you cry! All the advice I have seen says you should seal the (screed) with PVA before pouring the self-leveller. However, I am not in the UK and I have not seen PVA for sale here. What alternatives are there? (An old builder here suggested what they call "milk", which turns out to be a thin water/cement mix. Any old UK builders heard of this?)
Thanks in anticipation.
