Question: will teak DARKEN after being varnished if sitting outside? Using Epifanes WoodFinish, which is quick build so slightly less UV protection I’m told.

Question is newly planed teak is always lighter, and after sitting even in the shop tends to darken up… Sun will definitely tend to darken it, but I’ve also seen it darken just sitting which leads me to believe the oils/waxes start coming to the surface and tend to darken the wood.

Will this happen after having a varnish on it?

Long story short is I fabricated some HIGHLY complex panels to use as a dashboard, and now that I’m varnishing them the grain is not optimum. Seems quite light.

ANY input on how teak behaves after a spar varnish will be appreciated…I just never really paid that much attention as I’m usually happy with the grain I get.. NOT this time.

Long story short teak behaves badly under varnish. There is a saying that refers to teak on boats that goes “Varnish is for boat lovers. Cetol is for boaters.”
Varnish on teak is great if you make the commitment to keeping it up but it will be a chore for life.

I’d use King Starboard before I’d apply any cetol to any wood on my boat… I have a very small, and manageable amount of teak on my boat so I find it more appealing but I agree with you 100% that this will be a chore for life, but one I thoroughly enjoy.

This is the first couple pieces of teak that color did not come out to my liking…

I’ve found teak will darken no matter what I put on it. As you mentioned it’s the oils that oxidize on the surface I think?
But I’ve also found all woods eventually turn gray outside in us rays. Unless your meticulous about keeping up the finish.
Good Luck

You are entitled to your passion, I applaud it. I used to feel that way too but after a few decades of boats I find that I have less passion for the upkeep and by the way Cetol is no longer your father’s Cetol. Properly applied with the clear gloss topcoat it’s hard to tell from varnish.

My uncle’s old Mastercraft had a teak boarding platform we used Cetol on as needed, usually every couple years and it looked great until he sold it in ‘13 for a new Mastercraft, this time with an integrated fiberglass platform, far less visually appealing but certainly less maintenance.

Now that is interesting… The cetol I’ve used typically obscures any grain… I have found it to be a bit to “orange” for my liking… and I like orange…lol.. just not on my teak…

I’d love to see an example if you ever come across one…

Not the best pic. This is 35 year old teak revived from the dead. I’m using one or two coats of Cetol marine and about five coats of thinned Cetol Clear gloss. They have a natural teak that you can use instead of the marine but I prefer this colour. I just did my annual maintenance last week. For all my trim it took an hour one day and a half hour the next. The pic doesn’t really show the gloss.

I use the Star brite premium (not the regular) teak oil on the platform on my 96 Ski Nautique and I have a couch and six person table with chairs in my backyard made of teak and use the same stuff. Turns it a beautiful golden color. That’s a personal preference but we like it. Holds up well too but there is maintenance. About 15 minutes of reapplying one time a year on it.
