What PSI and Technique Do Professionals Use for Power Washing Stone?
For power washing stone, professionals match pressure to the material: low pressure or soft washing for limestone, travertine, marble, and flagstone, and moderate, controlled pressure for concrete pavers. Crews identify the stone, check for existing sealant, and test pressure on an inconspicuous corner first, using wide spray patterns and pH-balanced detergents.
