Hi all - builders have finishing contructing a new room at the top of the house and now its down to me the decorate. They have screwed all the skirting boards on and deeply countersunk the screws. Any suggestions as to what's best to fill the holes prior to painting. I've never found wood filler that easy to get a really good finish with and ideally I want something that'll be resistant to shrinking and cracking.
All suggestions gratefully received.
TIA
Peter
