Will saltwater harm honed sandstone coping tiles in any way?
Firstly, you should only have water that is treated with salt – not ‘saltwater’. Pool water will always leave deposits in the pool and the surrounding area. If the coping is correctly sealed with a high quality stone sealer it will be fine if it’s kept clean and deposits are hosed and bushed off on a regular basis. I’d also suggest sealing the sandstone coping a couple of times a year.
