Topic tags/keywords: finishing outdoor meranti resource question

Hi felow LJ’s. I just finished two folding Adirondack chairs using Meranti. Meranti is a Malaysian Hardwood used a lot for window and door frames and is suppose to stand up really well outside. My problem is I don’t know how to finish it. Anything I’ve tried on outdoor projects has never stayed on very long and exterior varnish is just a waste of time. I was thinking about just putting a coat of boiled linseed oil, whch really makes the colour pop. Has anyone ever tried BLO on an outdoor project? How did it work out for you. Or, of course any other finishes that you have had good luck with. Thanks Bruce

I would try Minwax Helmsman spar urethane. It’s supposedly UV resistant and can expand with temperature/humidity changes without cracking. I’ve never actually used it for an outdoor piece, though.

About the best finish for outdoors is Sikkens and it is really expensive. Last time I used it I think it was $75 per gallon and it is only sold through distributors.

Any type of oil that is rated for exterior use will protect the wood but still allow it to turn silver over time. There are no U.V. inhibitors like in the Sikkens product.

Many of the guys I know use Messmers instead of Sikkens and it is more widely available at the chain hardware stores.

One other thing to keep in mind when it comes to outdoor finishes is this, regular maintenance is much easier and less costly than letting the finish deteriorate to the point of needing stripped.

The surface coat is sacrificial. It should get a light sanding and a new coat applied every couple of years or as necessary depending on the project’s needs.

Thanks for your input, Sikens I’m quite familiar with, my home is board and batten and it took 17 gallons to complete. :)

Sometime in the last year, FWW had an article on exterior finishes. The best is several coats of thinned epoxy, followed by a UV inhibiting varnish or polyurethane.

Gerry – I missed that one, I will have to check it out.

I admit that I gravitate towards canned products due to my background as a remodeling contractor.

I remember that test in FWW and the conclusion was that a marine varnish was best and that epoxy with poly which had uv inhibitors wasn’t any better than the poly alone. Sorry Gerry, I’m not trying to be ornery, but if you reread that article you will see I’m right.

I re-read the article (at least the last paragraph), and the conclusion was that the 7 coats of Epifane varnish was equal to 3 coats of epoxy + 5 coats of Epifane. Both were better than poly alone.
