One room in my house has been occupied for the last ten years by a very heavy smoker, so I'm redecorating it.
The walls are coming up fine with a hard scrubbing and a repaint, but I'm not sure what to do about the woodwork, which was painted ten years ago with white gloss.
It's all in very good condition -- no flaking, very few dents and chips etc -- and in other conditions, I would be happy to just sand it with wet-and-dry, touch up the chipped bits, and then paint one undercoat before re-glossing.
However, the normal sanding doesn't entirely remove the yellow stain. I don't think I need worry about it showing through the paint, but I do worry about it not providing enough adhesion.
Can anyone tell me whether I need to sand off all the yellowed stuff?
Thanks!
