I'm going to fit some lightweight polystyrene type coving. Where the long, straight lengths of coving join the corner pieces, there will be a line/join.
Is it normal to fill these joins so they don't show, or just leave them? If yes, what type of filler is best?
I'm a bit worried that if I put filler on and sand down, I will wear away the soft polystyrene surface of the coving. Any advice on best technique appreciated.
