got my sandstone flags to finish off round my decking area today, but just wondering wether or not to give them a coat of impregnating sealer or not (I am keen to try LTP's new H20 sealer too). It'll be simple enough to keep the unsealed flags clean enough with my pressure washer but I really don't want to blast the pointing out of the joints. So my idea is to seal with the H20 and then turn the pressure down on my washer so as not to damage the pointing. Any thoughts folks?
