Why Pressure Washing Before Painting Matters

Paint sticks to clean surfaces. Pressure washing removes dirt, chalk, and mildew before exterior painting so the new coating can bond and last.

Pressure washer cleaning mildew off the siding of a home

Pressure washing before painting removes dirt, chalked paint, and mildew so the new coating bonds to a clean surface. Painting over a dirty or chalky wall leads to early peeling.

Paint needs a clean surface

Exterior walls collect dust, pollen, pollution, and chalked paint residue. New paint cannot grip through that layer, so it fails early even if the paint itself is fine.

A thorough wash clears the surface so the coating bonds to the siding itself rather than to the grime sitting on it.

Mildew has to go

In Alabama's humidity, mildew is common on shaded siding and soffits. Painting over mildew does not kill it; it keeps growing under the new film and stains through.

Washing removes the visible growth and gives the new paint a clean start. The surface also needs time to dry before any coating is applied.
