Using Indian Sandstone Patio Flags Indoors? Help, advice, information, answers and tips on all types of flooring from laminate and carpet to timber and vinyl

[Maca]

I have some Indian sandstone flags left over from a patio project. I was thinking to use them in my Hall. Is this OK? There is an existing concrete floor in the hall and I've recently lifted the old tiles, cleaned and sealed the concrete. I can adjust the doors so there shouldn't be any physical reason I can't but just wondering if there is any reason the stone for patio flags won't be suitable for inside. I'll seal them afterward so any advice on best sealant would be good.
