I was looking at osmo but I thought it was for interior applications only?
Osmo UV protection oil 420, the manufacturers say two coats will give a four year protection
The timber has maybe lasted 130 years but unless it is treated every few years, it will lose it's treated colour. Untreated wood will go a silvery grey (nice according to some people) but not a scratch on timber which is retreated every few years. If anyone can remember the time before plastic windows, wooden windows used to get a coat of paint every couple of years or so and they lasted a lifetime.
It amazes me that people will have timber fitted to a building or buy garden furniture and listen to the rubbish advice dished out "leave it to go grey" it will go grey and it will also become rough, splintery, scratchy and uncomfortable to use. Folks think nothing of shelling out shed loads of money on servicing some shiny car every year but ignore the place they are living in which is going to be standing long after the car is in the scrap yard (if looked after the same way and with less monetary outlay)
Depending on prevailing weather conditions, timber will need different care, timber facing South will be bleached by the sun, timber facing North will have moss growing on it, it's drier in Norfolk than Wales etc etc etc. These factors all add up to how often the timber needs treating and with what.
Timber needs looking after, it doesn't grow on trees you know!!!!!!!!!!
