Prep work from the Amtico job above. Old click LVT and parquet flooring underneath was uplifted and disposed of, which left a height difference of 22mm and a damp floor. To overcome this we used x3 coats of moisture tolerant latex screed and a liquid DPM. This left the floor the correct height with the original skirting so as to not leave a gap and a smooth, dry floor to lay the Amtico on
