Hi, we are having new luxury vinyl flooring fitted next week and all out old flooring is up, we have a concrete floor and I want to take the opportunity to run a HDMI cable between 2 rooms, is it advisable to chisel a channel or not? It wouldn’t have to be deep and hoping it would be filled in by the levelling compound the flooring guys use. What would be the best way to do the work by hand without much dust please.
