Is there some kind of sealer that I can apply to the underside of a stoop that is made of carved sandstone that will stop, or help prevent, the stone from dusting. I can clean the stone down to a solid surface but then, in time, it will start to dust again. I think what I’m looking for is something that will soak into the stone and harden but will still let the stone breath. I live in New England so it will go through a lot of freeze thaw cycles.
