Most house painting professionals will agree that two coats of paint are needed on a home. Using one coat of paint may look sufficient, but will not hold up over time. Two coats of paint, on the other hand, provide protection, washability, and help retain the true color of the paint. If you are still toying with the idea of hiring a professional painter, ask if two coats of paint are included in the pricing estimate.

Like the rest of your home’s exterior, you should start from the top down when painting exterior trim. If your window sills look particularly weather-beaten, you might want to give them a second or third coat of paint.

The strength of oil-based paints makes them a great choice for moldings and trims.
