Tropical Weather Varnish

2 posts in this topic

We have a good amount of varnished teak on the exterior of our 35' sailboat kept in FL.


Previous owners had stripped it to bare wood and use cetol natural and then cetol gloss.  We had good results with this with 2 annual maintenance coats of cetol gloss for 8 years.  The only issue was that it was hard to fix a spot that had to be sanded to bare wood without it being obvious that is what was done (color didn't match). 


Last fall we stripped the toerail to bare wood and went with 8 coats of epiphanes.  The epiphanes is quite sensitive to dew at night (hard to find a night that does not dew here in FL) and also is not holding up all that well, we already have spots worn thru to bare wood in less than a years time.


We need to do cockpit surrounds and cabin top rails this fall so I am starting the search for the best option.


What are the thoughts of the new total boat Lust Varnish for long term adhesion to bare teak?  How is it expected to wear compared with cetol or epiphanes? 


Second question - can it be applied over epiphanes in good condition?

Lust is a spar varnish that is fast drying allowing multiple coats in a day.  In Florida I wouldn't expect much better results than the Epifanes unless you first seal the teak with a clear penetrating epoxy.  One of the reasons varnish fails is that moisture gets into the wood causing spots to fail.  If the teak is sealed prior to applying varnish it should help the finish to remain intact.  You can apply Lust over other varnish in good condition.  The other cause of failure is UV damage where Cetol advertises a UV-absorbing technology and being more flexible will allow natural expansion and contraction and allows moisture to escape.
