Hi All, As a lot of you will know from my other thread, I am having to open the channel in my wall where my broken HDMI cables are and re-run the HDMI cables but this time use trunking. However my run for the cables is an L shape and I wondered what the best way is to do the corner? As I am worried (maybe unnecessarily) that when plastered over that the plaster may seep into any joint and stick to the cable. Am I worrying unnecessarily? have any of you had this problem? How did you get round it?
