Just screeded 3m x 3m bathroom ready for quickstep lvt. Not had much experience with the glue down or screeding. Im going to get a couple of courses under my belt when i get chance. Can anybody tell me if the screed would need rubbing down before the glue goes on? I used ardex k39 screed and its completely flat. Also whats the best glue for it? Was looking at the quickstep livyn glue but never used it.
