How to Pressure Wash Your House Before Painting

Pressure washing your house before painting is an important step to ensure that the new paint adheres properly and looks great. Here are the steps you can follow:

  1. Choose the right pressure washer: Select a pressure washer with at least 2,000 PSI (pounds per square inch) of pressure and a flow rate of at least 2.5 GPM (gallons per minute).
  2. Prepare the area: Remove any outdoor furniture, decorations, or plants from the area you will be pressure washing. Cover any electrical outlets or light fixtures with plastic bags to prevent water from getting inside.
  3. Pre-rinse the area: Use a garden hose to pre-rinse the area you will be pressure washing. This will help remove loose dirt and debris.
  4. Apply detergent: Apply a detergent solution to the surface of your house using a low-pressure nozzle. Allow the detergent to sit for 10-15 minutes.
  5. Pressure wash: Attach a high-pressure nozzle to the pressure washer and begin washing the surface of your house. Start at the top of the house and work your way down, using long, sweeping motions. Keep the nozzle at least 6 inches away from the surface of the house to avoid damaging it.
  6. Rinse: Rinse the house thoroughly with clean water, starting at the top and working your way down. Be sure to remove all detergent residue.
  7. Allow the house to dry: Allow the house to dry completely before painting. This may take several hours or even a full day depending on the weather.

By following these steps, you can pressure wash your house before painting and ensure that the new paint adheres properly and looks great.
