Preparing the exterior surface of a house or other structure properly before applying paint is equally import as painting itself. If you are going to take the time and effort to paint, you should prep it in a way that will allow the paint to adhere properly to the surface. Doing this will allow it to look nice for a lot longer than if you do not complete the necessary preparation work. Working on the exterior of a structure usually requires additional tools and equipment. For example, on most houses or structures, ladders will be a necessity. You may be able to get by with an 8′-13′ step ladder if you are working on a ranch-style building. For larger homes with two or more stories you will need to have a longer extension ladder. A power washer is also an additional tool required for painting the exterior. Even though the house or structure being painted may not appear dirty, IT IS. In order for paint to adhere to the surface properly, you must get the majority of the dirt and chipping paint off of the structure first. If you are planning to paint the exterior of your home yourself, which will probably save you at least $1,000, but are not sure of the proper process, here are step-by-step instructions to properly prepare the exterior surface.
