Can marble outdoor seating withstand pressure washing without surface degradation?
Marble outdoor seating is prized for its elegance and durability, but many wonder if it can endure pressure washing without surface degradation. The answer depends on factors like marble quality, sealant application, and washing technique.
High-quality marble with a proper sealant can generally withstand low to moderate pressure washing (under 1,200 PSI). However, excessive pressure or harsh nozzles may erode the surface over time. Always use a wide-angle nozzle, maintain a 12-inch distance, and avoid acidic cleaners.
For routine cleaning, gentle soap and water are safer alternatives. Regular sealing (every 1-2 years) significantly enhances marble’s resistance to pressure washing and environmental wear. By following these guidelines, your marble furniture can retain its beauty for decades.
