If you’re looking to revitalize your patio, driveway, or walkway, you’ve likely asked the big question: Can you power wash pavers? The short answer is yes, but it must be done correctly to avoid damage. This complete guide will walk you through the safe and effective methods to make your pavers look brand new.
The Benefits and Risks of Power Washing Pavers
Using a pressure washer is a fast and efficient way to remove deep-seated dirt, moss, mildew, and stains from paver surfaces. However, the high-pressure stream can be a double-edged sword. Done improperly, it can erode the joint sand between pavers, damage the paver surface itself, and even create a hazardous, slippery film.
Choosing the Correct Pressure and Nozzle
This is the most critical step for safety. Never use a high-pressure, zero-degree (red) nozzle on pavers. Instead, opt for a 25-degree (green) or 40-degree (white) nozzle. Start with the widest fan and the lowest pressure setting that is effective, typically around 1,200 to 1,500 PSI for concrete pavers. Always keep the nozzle moving and maintain a consistent distance of at least 12 inches from the surface.
Essential Pre-Cleaning and Post-Cleaning Steps
Preparation is key. Begin by sweeping the area thoroughly to remove loose debris. Pre-treat any oil or organic stains with a dedicated cleaner. After power washing, the most important task is to replenish the joint sand that was inevitably displaced. Apply new polymeric sand, sweep it into the joints, and lightly mist with water to activate the binding agents. This stabilizes the pavers and prevents weed growth.
