How to Pressure-Wash Pavers

Large gaps will need to be filled with dry mortar or concrete sand after pressure washing.

Cleaning pavers that were properly installed is a simple task. A pressure washer and concrete cleanser will work wonders to remove dirt and debris. The only requirement before cleaning is to inspect the pavers. Look closely at each edge to verify that the edge pavers are firm and immobile. Look for signs of loose or damaged pavers. Repair or replacement is not necessary, but you will want to take care in cleaning any loose sections.

Things You'll Need

• Pressure washer
• Pump sprayer
• Concrete cleanser
• Stiff-bristled broom

Instructions

1. Spread a concrete cleanser over the surface of the pavers with a pump sprayer. Dampen the entire surface with the cleanser.

2. Scrub the surface of the pavers with a stiff-bristled brush. Allow the cleanser to remain on the pavers for approximately 15 to 30 minutes. Do not let the liquid dry.

3. Rinse the pavers thoroughly with a pressure washer, taking care to avoid any weak joints or loose pavers.

4. Repeat the process as necessary to remove stubborn stains.

Tips & Warnings

• You will want to seal your pavers every two to three years with an approved sealant. Refill grooves and gaps in the pavers with concrete sand by brushing the sand into the grooves with a broad-head broom after cleaning. Wet the sand down with a water hose and allow the surface to dry before sealing.
