andrewg:Whats the best way to channel a wall, i thought about just using my angle grinder to cut a 5-6mm line down the wall, and do you need to prep the cable or coat it with anything
Before cutting,hitting anything,establish what type of wall you are attacking. Brick/plaster or lathe/plaster or plasterboard,then find out if there are already any cables in there. Then come back and request further help.
