Hi, I want to use woodstain on a cupboard, not MDF but I am told it is better quality wood, which has never been painted before and I have bought Dulux Trade Woodstain. Asking in the shop whether I needed to sandpaper the wood down first, I had two different replies from them, yes and no. Can anyone please advise whether I need to sandpaper and also if I put on two coats, will I need to sandpaper between coats. It is a big cupboard so don't want to do any unnecessary work. I looked at the Dulux Datasheet 605 as per the tin and it doesn't mention sanding. Thank you for any replies received.
