Frequently Asked Questions
Why is power washing necessary before painting?
Power washing removes dirt, mildew, chalking old paint, pollen, and other contaminants that prevent new paint from bonding to the surface. In Texas, exterior surfaces accumulate significant mold and algae growth due to heat and humidity. Paint applied over dirty surfaces peels within months. Every professional painter considers power washing the single most important step in surface preparation for a lasting paint job.
How much does power washing before painting cost in Texas?
Power washing for painting prep in Texas costs $250 to $600 for a full home exterior. Most painting contractors include power washing in their painting estimate. If hired separately, expect to pay $0.10 to $0.40 per square foot depending on surface type and contamination level. Deck and fence washing costs $150 to $400. The cost is a small fraction of the painting project but dramatically extends paint life.
How long should surfaces dry after power washing?
Surfaces must dry for 24 to 48 hours after power washing before paint or stain application. In dry Texas summer weather, siding may dry in 24 hours. Wood decks and fences need a full 48 hours to allow moisture to evaporate from the wood grain. Painting over damp surfaces traps moisture under the paint film, causing blistering and peeling. Professional painters schedule wash and paint days accordingly.
What PSI should be used for washing before painting?
House siding should be washed at 1,200 to 1,500 PSI to avoid damage to wood and fiber cement. Soft washing with chemical cleaning solution at lower pressure is preferred for delicate surfaces. Concrete and masonry can handle 2,500 to 3,000 PSI. Wood decks and fences should stay under 1,500 PSI to prevent wood fiber damage. Professional washers adjust pressure based on surface type and condition.
Can power washing damage siding before painting?
Yes, excessive pressure can damage wood siding, drive water behind lap joints, and gouge fiber cement boards. Soft washing at lower pressures with cleaning chemicals is the safest approach for siding. Never spray upward under lap siding as water will infiltrate behind the boards. An experienced pressure washing technician knows the proper angles, pressures, and nozzle tips for each surface type to clean effectively without damage.
Should I power wash or hand scrape before painting?
Both are typically needed for exterior painting prep. Power washing removes surface contamination, mold, and loose paint. Hand scraping follows to remove any remaining loose or peeling paint that the pressure washer did not dislodge. Professionals power wash first, let the surface dry, then scrape and sand problem areas. This combination provides the best surface for new paint adhesion and long-term performance.
