I have been doing my skirting and have used various methods to fill gaps (its painted so no worries) and hide the counter sunk screws. Just wanted to get a bit of a debate on the best methods. I have used 1. Caulk - on the tops for wonky walls 2. All purpose filler - for the screws 3. Wood filler - for small gaps at the scribed internals. Anybody have and preference or can caluk be used for the lot? One more thing - one plank i did has a gap below it of 5mm. How best to deal with it or at least minimise it. Beading is not a option!
