Preparation is key to a superior house painting job. The hours of prep work give the finish that finished look.  If you are a house painter, then preparation will include: scraping, repairing and sanding until it’s smooth, then put it back together with attention to every step. After meticulous prep work, you need to apply primer and two top coats. The primer seals and allows the first top coat to adhere. The second top coat gives the room a finished, complete look, with smooth even color and texture. Double priming may be needed in some circumstances, such as when changing colors, or when the walls are very dry. A third top coat is sometimes needed when changing to a darker color.
