This video is about Paint The Exterior Of A Home. To estimate the exterior wall surface area, measure the entire perimeter of the home. As a general rule of thumb it will take 1 gallon of trim paint for every 8 gallons of body paint. Although this could vary depending upon the type of paint and the surface area requiring paint.To determine the number of coats your project requires examine the surface area. Porous, rough, textured, and previously unpainted surface areas will require more paint. The same is true when there is a huge difference in color.
