To ensure that the paint adheres to the furniture, it's best to sand the furniture first. Sanding is important to remove an existing smooth finish that may repel the paint, or to smooth out rough wood so the paint goes on evenly.

Refinishers can use latex primer with latex or oil-based paint, but only use oil-based primer with oil-based paint. Oil-based paints stick to the wood better, but have a very strong odor.Learn more about Furniture
