Remove accumulated paint
Whether the paint that’s already on it is water-based or oil-based, wood trim usually looks best if the built-up paint is removed before you apply fresh paint.
- But, if the trim already has five or fewer coats of an oil-based paint, then you could probably get away with adding a fresh coat or two on top.
- This short cut won’t work for water-based paint, though.
- So if you’re planning on repainting trim that’s been painted with water-based paint, then you’ll have to sand or strip the old paint away before applying a new coat.
