although all timber gets bleached by the sun and goes grey so after a few moths to a year it will all turn grey (unless re treated/oiled)
I'm surprised at a pine as its a softwood so would need to be tanalised treated.
and Treatment wise you get a green or brown tanalith (pressure treatment) for softwood to stop it rotting but it wont last forever? however as its not in ground contact it would last longer.southern yellow pine is a heavier pine but still softwood.
you used to be able to use creosote but that's banned now, well the chemicals in it.
A hard wood would last a lot longer and not rot as quick? but be 3 times more expensive.
But I guess they know what they are doing
Hardwood isn't a sustainable resource. Not only will it cost a huge amount to make an entire coaster from hardwood, but many environmentalists wouldn't be very happy. Yes it's stronger and can last for longer, but it's much cheaper just to replace the pine every so often.
