Yes — professional power washing is one of the most important steps in prepping a home for painting or staining. In fact, most paint manufacturers, contractors, and coating specialists require exterior cleaning before applying any new coating. Power washing removes dirt, chalking, oxidized paint, mildew, algae, and contaminants that prevent new paint or stain from properly adhering to the surface.
When this prep is done using proper techniques — especially soft washing for siding and delicate materials — the new coating lasts significantly longer and looks dramatically better. Many homeowners and painting contractors rely on the pros found in the PowerWashing.com Directory to ensure surfaces are cleaned to professional standards before any painting or staining project.
Here’s the full breakdown.

The drying time depends on the surface and weather conditions.
Typical Dry Times:
Painting over damp surfaces causes blistering and adhesion failure.
Many PowerWashing.com contractors provide guidance on ideal drying windows and even coordinate directly with paint crews.
⭐ 5. What About Removing Old Paint?
Power washing alone is not a full paint removal method, but it does remove:
For complete paint stripping, additional sanding or chemical stripping may be required.
Professionals ensure that:
This prep dramatically improves the quality and longevity of the new finish.
