Hi I am replacing the wood on a park bench with a metal frame. Teak, I don’t want to let it go to grey. Any suggestions, I have been told spar varnish.30 May 2015 at 3:11 am #127397Matt McGraneParticipant
I think there are some varnishes specially designed for outdoor use. And some of them have UV inhibitors to slow down the sun’s effects. Another idea might be teak oil, but I don’t think that will help with the graying.

Thanks Matt, I think varnish would be longer lasting than oil.30 May 2015 at 11:00 pm #127407Steve FollisParticipant
General Finishes makes two clear products that I have used successfully,
Exterior 450 is a varnish with a harder finish, however your bare skin may stick to it, and it will feel warmer in the direct sunlight.
The Outdoor Oil leaves with you with a more natural wood feel, you won’t stick to it and it doesn’t warm up like the harder finishes do.
For preservation of the natural color, the 450 would probably do better, but will require some routine maintenance to keep the finish fresh.

If it is for someone else, I would try to convince them of the merits of letting it go grey with minimal preservation. That is after all the main benefit of using teak.
All exterior finishes need regular maintenance to remain at their best, there’s no escaping it, and even more so on a bench which will be subject to mechanical wear and the full blast of the sunlight. Personally I am biased against exterior varnishes because of the time involved in maintenance, however if it is possible to remove the wood from the metal frame when it needs re-finishing varnish becomes much more viable.
