It is generally acceptable to pressure wash pavers, but whether it is truly "OK" depends entirely on the type of material your pavers are made from. Using a pressure washer on the wrong type of paver can lead to significant damage.
Pressure washing can be an effective method for cleaning outdoor surfaces, but the intensity of the water jet necessitates a careful understanding of the underlying material.
Understanding Paver Materials and Pressure Washing Suitability
The composition of your pavers dictates their resilience to high-pressure cleaning. Different materials react distinctly to the force of a pressure washer.
| Paver Type | Pressure Washing Suitability | Explanation |
|---|---|---|
| Natural Stone | Generally OK | Pavers made from sturdy and tough natural stones like granite or basalt are resilient enough to withstand the high-pressure water jet without damage. |
| Concrete | Not Recommended | The intense water jet can quickly damage the surface of concrete pavers, leading to undesirable erosion, pitting, or discoloration. |
| Terracotta | Not Recommended | Similar to concrete, terracotta pavers are susceptible to surface damage when exposed to a high-pressure water stream. |
Why Paver Material Matters for Pressure Washing
Natural stone pavers, such as those crafted from granite or basalt, possess a dense and inherently robust structure. This allows them to withstand the direct force of a pressure washer, making them suitable candidates for this cleaning method. Their hardness ensures the surface remains intact under high pressure.
Conversely, pavers made from materials like concrete or terracotta are typically more porous and softer. The powerful water jet from a pressure washer can quickly erode their surface. This can lead to a compromised appearance, including pitting, rough textures, and a general degradation of the paver's integrity. For these more delicate materials, the risk of damage often outweighs the benefits of high-pressure cleaning.
