How To Pressure Wash Patio Stones

Essential Aspects of Pressure Washing Patio Stones

Maintaining the pristine beauty of your patio stones requires regular cleaning, and pressure washing is an effective method for removing dirt, grime, and stubborn stains. Follow these essential steps to ensure a thorough and safe pressure washing process.

Preparation

Begin by clearing away any furniture, plants, or debris from the patio. Inspect the stones for any loose or cracked pieces that may require repair before pressure washing. Protect surrounding areas, such as walls or vegetation, with plastic sheeting or drop cloths to minimize overspray.

Choose the Right Equipment

Select a pressure washer with a pressure rating between 2,000 to 3,000 PSI (pounds per square inch) for patio stones. A higher pressure may damage the stones, while a lower pressure may prove ineffective. Utilize a nozzle with a wide spray pattern (40-60 degrees) to ensure even coverage and prevent etching.

Adjust the Pressure and Angle

Adjust the pressure of the water to an appropriate level for patio stones. Start with a lower pressure and increase gradually if necessary. Hold the nozzle at a 45-degree angle to the stones to avoid direct and perpendicular impacts, which can cause damage.

Use a Detergent (Optional)

For heavily soiled patio stones, you may consider using a specialized pressure washer detergent specifically designed for stone surfaces. Follow the manufacturer's instructions for diluting and applying the detergent.

Pressure Wash in Sections

Begin pressure washing a small section at a time, working from one end of the patio to the other. Start by directing the spray from the outer edges towards the center to prevent water from splashing out. Overlap each pass to ensure thorough cleaning.

Rinse and Dry

After pressure washing, rinse the stones with clean water to remove any remaining detergent or dirt. Allow the stones to dry completely before walking on them or placing furniture back on the patio.

Additional Tips

Always wear safety goggles and gloves when pressure washing.
Never point the pressure washer nozzle directly at people, pets, or electrical outlets.
If you encounter stubborn stains that do not respond to pressure washing, you may need to use a specific stain remover designed for patio stones.
Regularly pressure washing your patio stones (every 1-2 years) will help maintain their beauty and prevent the buildup of dirt and grime.
