Finish Failures Can Darken Wood (Tuggers Vol. 63)


This past summer, while the crew of Cruz-In 37VT74 was away, a deck leak allowed water to drip and pool inside the liquor cabinet. The picture shows the dramatic effect on the surrounding wood's color. The teak wood in both the deck and on the sides of liquor cabinet was the most affected. The laban in the floor, the yard used laban in lieu of holly, was also affected but less so. Interestingly, the areas of darkened wood weren't underwater but are structurally connected to the wet area. Perhaps water vapor is migrating under the finish of the connected components. Whatever the cause, the good news is that removing the finish and then lightly sanding the wood brings the original color back.

There's evidence that Cruz-In's wood darkening is happening on Nellie D. 37VT63 too.  And as in Cruz-In's case I believe the explanation has to do with water (humidity) and the OEM wood finish.



The above picture is of a darkened spot in Nellie's pilothouse.  I suspect that water or humidity penetrated the finish.   I'll follow Cruz-In's example in the repair process.
