FAQ: Varnish over Oiled Teak
How do I varnish over oiled interior teak?
Original Message:
The previous owner oiled the interior teak in the
cabin. I prefer a varnished finish. Anyone know whether the oiling is
going to present problems in varnishing? Anyone done this? Any tips,
secrets or suggestions?
Thanks for the info!

All my interior teak used to get white growth on it when
the winter cold set in. I had success with my last boat in using varnish
on the teak, so I decided to try it on my C34. After varnishing, I did not
see any growth the past two winters. Excess teak oil had to be dealt with
first. I washed all the walls and wood work with Brush Clear..the water
soluble type. Then I wiped all walls and woodwork with acetone. Then I
applied three coats of Helmans Semi-gloss varnish. It gives the boat a
nice low luster wood look and is easy to clean. If it gets scratched, I
carry a touch up bottle of varnish and some fine sandpaper. Because it is
not in the sun, any touch-ups could wait till the next spring. No
maintaince should ever be needed to the woodwork other than normal
cleaning. Try not to use a gloss finish as it will show any defects and
not look as rich looking.

Maybe. I have had good success using Deks Olje #1 &
2 on a previously oiled teak table and a yellow poplar mast on a homebuilt
boat. The #1 is a matte finish and the #2 gives it an almost varnished
look. Well, at least it’s shiny. It isn’t very rugged but it has the
advantage of being easy to refinish. Just wipe more #2 on with a rag.
I recommend you test on an area that doesn’t show no matter what you end
up applying to the teak.

I refinished the interior our C34 using Daly’s
Pro-Fin.
Pro-Fin is a resined tung oil which produces a bright durable finish that
can be easily repaired by wiping on another coat.
Daly’s also produce a tung oil without the resin additive for external
use. Its called Sea-Fin.
I prepared the original oiled teak by spraying with domestic bleach
solution and rubbing in the grain direction with fine bronze wool. This
removed dirt and mold and lightened the surface. Bleaching is not a
pleasant job and must be done with lots of ventilation or you’ll end up
coughing for day’s after. You’d need to clean the surface in much the
same way if you were going to use a regular varnish. After allowing the
wood to dry, I then wiped on two coats of Pro-Fin. Each coat is liberally
washed on, allowed to stand for a few minutes and then any excess is wiped
off. The second coat can be applied a few hours later.

I’ve used tung oil as a first coat to seal wood before
varnishing and it seems to work fine. I’ve always used oil based rather
than a poly or synthetic varnish. I’m not sure what happens if you put a
poly over an oil. On the other hand, I have found that a couple of coats
of tung oil wet sanded on with a fine grit emery paper can produce a
smoother finish that lasts longer on interior teak than using varnish. It
won’t hold up on exterior teak. Personally, I’ve found tung oil easier
to work with than varnish especially on vertical surfaces and easier to
touch up if there’s any dings—just rub some more on, smoothing it out
with emery paper, if needed.
