We are thinking of getting some sand stone paving installed, however we have to be able to use lots of deicing salt in a bad winter.
Will the salt stain the sand stone?
Any other issues we should be aware of?
Salt on stone can cause pitting, but it should be okay as long as you don't over-do it. If you still have visible salt crystals after the ice has gone, you're using too much. If you have trouble both avoiding visible crystals and clearing enough ice for safety, try using a sand/salt mix.
