Can You Pressure Wash Pavers?

July 15, 2024

Yes, you can pressure wash pavers safely—but using too much pressure or the wrong nozzle can damage the surface and wash out the joint sand that keeps the patio stable. The key is using moderate PSI, the correct spray angle, and consistent cleaning technique.

Here’s how to do it correctly.

Helpful Patio Washing Tips:

  1. Choose the Right Pressure: Use a pressure washer with a 1000-1500 PSI setting to avoid damaging the pavers.
  2. Use the Appropriate Nozzle: A fan tip nozzle (25-40 degrees) is ideal for cleaning pavers. It spreads the water over a larger area and reduces the risk of damage.
  3. Pre-Treat Stains: For tough stains, you may want to pre-treat with a suitable cleaner before power washing.
  4. Test a Small Area: Test the power washer in a small, inconspicuous area. Be sure it won’t damage or change the pavers. Always start from far to near when testing your nozzle’s strength.
  5. Maintain Distance: Keep the nozzle about 6-12 inches away from the pavers to avoid excessive force that could damage the surface.
  6. Use Even Strokes: Move the nozzle in even, sweeping motions to clean uniformly and avoid streaks.
  7. Rinse Thoroughly: After cleaning, rinse the pavers thoroughly to remove any soap or cleaning solution residue.
  8. Re-sand if Necessary: After power washing, you may need to re-sand the joints between the pavers with polymeric sand to maintain stability. At Pristine Clean, we offer a polymeric sweep sand service.
  9. Seal the Pavers: Consider sealing the pavers after cleaning to protect them from future stains and weather damage.

Common Mistakes to Avoid When Pressure Washing Pavers

Pressure washing patio pavers can improve the appearance of your outdoor space, but using the wrong technique can lead to costly damage. Here are some of the most common mistakes homeowners make when cleaning pavers.

Using Too Much Pressure

More pressure is not always better. Excessive PSI can damage the surface of pavers, leave visible marks, or loosen the joint sand that helps keep the patio stable. Most paver patios should be cleaned using moderate pressure settings.

Spraying Directly Into the Joints

Pointing the nozzle directly at the joints between pavers can quickly remove sand and create uneven areas or shifting pavers over time. Always spray at a slight angle instead of straight down.

Holding the Nozzle Too Close

Keeping the nozzle too close to the surface concentrates the pressure and increases the risk of etching or cracking the pavers. Maintain a consistent distance of approximately 6–12 inches while cleaning.

Using the Wrong Nozzle

Narrow spray tips like 0-degree or 15-degree nozzles can damage pavers and wash out the joints. A 25–40 degree fan-tip nozzle is the safest option for most patio cleaning projects.

Skipping a Test Spot

Different paver materials react differently to pressure washing. Always test a small, hidden section first to confirm the pressure and technique will not damage the surface.

Forgetting to Re-Sand the Joints

If joint sand is removed during cleaning, the patio may become unstable over time. Reapplying polymeric sand after pressure washing helps maintain the integrity of the paver system.

Not Sealing the Pavers After Cleaning

Sealing your pavers after cleaning can help protect against moisture, algae growth, stains, and Ohio’s freeze-thaw weather conditions. It can also make future cleanings easier.

FAQs About Pressure Washing Patio Pavers

Can pressure washing damage patio pavers?

Yes. Using too much pressure or the wrong nozzle can damage the surface of the pavers and remove the sand between the joints. Proper pressure settings and technique are important.

What PSI should you use to clean pavers?

Most patio pavers can be safely cleaned using a pressure washer set between 1,000 and 1,500 PSI.

Will pressure washing remove polymeric sand?

It can if the pressure is too high or the spray is directed into the joints. Using a fan-tip nozzle and spraying at an angle helps reduce the risk of sand loss.

Should pavers be sealed after pressure washing?

Sealing pavers after cleaning is recommended because it helps protect against stains, moisture, algae growth, and weather damage while extending the life of the patio.

How often should patio pavers be pressure washed?

Most patios only need pressure washing every 1–2 years, depending on tree coverage, weather exposure, algae growth, and foot traffic.

Is pressure washing safe for brick pavers?

Yes, brick pavers can be pressure washed safely when moderate pressure and the correct nozzle are used. Avoid excessive pressure that could chip the surface or loosen the joints.

What is the best nozzle for cleaning pavers?

A 25-degree or 40-degree fan-tip nozzle is typically the safest and most effective option for patio paver cleaning.

Can you pressure wash pavers without removing sand?

Yes. Using lower pressure, maintaining proper distance, and avoiding direct spray into the joints can help clean pavers while minimizing sand loss.
