Can I Use a Pressure Washer on a Resin-Bound Permeable Courtyard?

Pressure washing is a common method for keeping outdoor surfaces clean, but when it comes to resin-bound permeable courtyards, a gentle approach helps preserve their structure and longevity. Here’s how to clean these surfaces without risking damage.

How to Pressure Wash Resin-Bound Surfaces

You can safely pressure wash a resin-bound permeable courtyard, provided you use the right settings. Always opt for a low-pressure mode and attach a wide spray nozzle. This minimises the force on the surface, helping to avoid disturbing any loose aggregates and protecting the bond between resin and stone. Hold the nozzle at least 20–30 cm from the surface and use a sweeping motion—never a direct, concentrated jet at close range.

Routine Cleaning and Stain Removal

Regular care extends the life of your courtyard. A soft-bristled broom or brush can be used for sweeping debris. For algae or moss, use an appropriate outdoor cleaner diluted with water before rinsing with low-pressure water. If you need a resilient, easy-to-maintain surface, Flowstone kits help create robust permeable flooring that stands up well to regular cleaning routines.

When Is Pressure Washing Most Important?

Pressure washing matters most after heavy pollen seasons, autumn leaf fall, or when moss and algae begin to make surfaces unsightly. Keeping your resin-bound courtyard clean not only maintains its appearance but also ensures continued drainage performance, preventing water pooling or slip hazards.
