When painting your home’s exterior, proper preparation is one of the most important steps you can take. Do thoroughly clean the surfaces with pressure washing or a hose and scrub brush to remove dirt, mildew, and loose paint. Do scrape, sand, and repair any damaged areas before applying primer, as this ensures better adhesion and a longer-lasting finish. Choosing high-quality exterior paint designed for your specific climate is another smart move, as it will resist fading, cracking, and peeling. Finally, always check the weather forecast—mild, dry conditions with moderate temperatures provide the best environment for exterior painting.

On the other hand, don’t skip priming bare wood, patched areas, or heavily stained surfaces, as this can lead to uneven color and premature failure. Don’t paint in direct, intense sunlight or during extremely humid or cold conditions, since these factors can affect drying time and overall durability. Avoid rushing the job or applying overly thick coats in an attempt to finish faster; this can cause drips, blistering, and inconsistent coverage. Taking the time to follow best practices—and knowing when to call in a professional—can make the difference between a paint job that lasts for years and one that needs attention far too soon.
