We've been looking at various options for a new patio area, limestone, sandstone, slate
and now granite. Yes, it's expensive but it does look nice.
However, SWMBO is worried about whether it will stain. What happens to it when you drop
butter, curry, red wine etc on it? Does it need to be sealed? Can it, and does it need to
be, cleaned? My thoughts are that it shouldn't be porous like limestone and sandstone but
even granite will have a surface that can retain grease etc.
Many thanks for your thoughts / experience.

Granite is as you say, not porous and pretty impermeable. There's a
question in my mind as to what is described as 'granite'. AIUI almost
any stone kitchen worktop is described as 'granite' regardless of it's
true geological category. Granite for patios may suffer the same
nomenclature imprecision. Not that it matters a lot.

Remember also that over time, any patio paving will get a patina of
algae or moss, and dirt etc. that will change its appearance from the
pristine attractive surface that it had in the brochure/showroom and
when first laid. Without regular and frequent cleaning, all external
surfaces of that general nature start to look the same.

Many thanks, Chris.
