Painting your house is one of those maintenance projects that most homeowners undertake at some point, whether it's the outside or the inside. With the exception of hardened DIY-types (you know who you are!), just about all homeowners will hire painters at some point—whether to prepare their home for moving in, or for a sale, or perhaps to kick off a remodel with a new color scheme.
If your home was built before 1978, there is a good chance that lead paint was used in its construction. Scraping, sanding, or removing old paint can release toxic lead dust which can cause serious illness in children and pregnant women. Special handling is required when working with lead-based paints. If lead paint is present in your home, you will need to hire a lead-certified painting contractor or lead abatement contractor. Before getting started with your exterior painting project, consult your local building authority or visit www.epa.gov for more information.
You can use the spray cleaner while working from a ladder -- although scaffolding is better -- but practice at ground level first; the force of the spray against the house could knock you off a ladder if you're not careful. Some of these machines come with separate containers you can fill with cleaning solutions or anti-mildew solutions. Sprayers are so powerful that ordinarily you probably won't need to use a cleaning solution; if you do, remember to rinse the surface with clean water afterward.
A professional painter will help you select an exterior paint designed for long-lasting results, superior protection, and ample coverage. Higher quality paint requires fewer coats and lasts far longer, saving you money down the road. Oil or latex paints in a flat/matte or satin finish make excellent choices for the exterior of your home. These paints will endure extreme weather conditions, can be customized to your specific climate, and are ideal for painting siding.
