Pressure Wash Stucco

Written by:

Stucco’s textured surface collects a lot of dust and dirt. A pressure washer can quickly blast away this buildup.

Before pressure washing, patch any cracks or chips in the stucco’s surface. Allow these patches to dry for a week before beginning the pressure washing project. Remove obstacles from the work area, cover nearby plants and electrical components, and close all windows and doors before pressure washing.

Tips for Pressure Washing Stucco:

  • To prevent streaks, spray cleaning solution from the bottom and working up in identifiable sections. Allow the solution to work five to 10 minutes. Don’t let it dry; keep it wet.
  • Use a rotating scrub brush attachment to scour heavily soiled areas of your stucco.
  • Switch to a delicate, low-pressure spray pattern, and flush remaining detergent from the system.
  • When you rinse the detergent, hold the gun and wand so the spray pattern hits the surface at a 45-degree angle, and keep the nozzle at least 24 inches away from the stucco.
  • Work from the top down to remove the detergent and residue.
  • Use a rust-removing detergent on rust and copper stains, and scrub by hand with a soft-bristle brush. Flush with plenty of clean water.
