Can You Power Wash Pavers? The Definitive Answer

The short answer is yes, you absolutely can you power wash pavers. It’s one of the most effective ways to blast away years of built-up dirt, moss, algae, and stains, restoring your patio, driveway, or walkway to its original beauty. However, doing it correctly is crucial to avoid damaging the pavers or the sand in the joints.

Essential Equipment and Pressure Settings

Using the right equipment makes all the difference. A gas or electric pressure washer with an adjustable PSI (pounds per square inch) is ideal. For most concrete or clay pavers, start with a low to medium pressure setting (around 500-1500 PSI). Always use a 25-degree or 40-degree wide fan tip nozzle, never a zero-degree pinpoint jet, which can etch and scar the surface.

Step-by-Step Safe Cleaning Guide

Follow this proven process for safe and effective results. First, clear the area and sweep away loose debris. Pre-treat any oil or organic stains with a dedicated cleaner. When washing, keep the wand moving steadily 6-12 inches from the surface, working in small sections. Pay special attention to not dislodging the jointing sand for too long in one spot.

Post-Wash Maintenance is Key

After power washing, your job isn’t quite finished. Allow the pavers to dry completely for 24-48 hours. Then, you must replenish the polymeric sand in the joints. Brush the new sand into the gaps and use a plate compactor to settle it, followed by a light misting to activate the binding agents. Finally, applying a sealant will protect your pavers and make future cleanings much easier.
