How do you paint a door?

To paint a door, you can remove it from the hinges or paint it standing up. The first step is to prime the doors. Then, you can paint the door.

Consider the time of year when you are painting because you don’t want the temperature to be too hot or too cold. When you purchase a door from Window World, you can choose from a wide selection of door colors.

Window World did two replacement casement windows and one patio door. They came on time, were professional and completed their work in a timely manner. Used drop cloths on floors and furniture.
