Originally Vespera had a glued teak deck. About 2000 tiny retainer screws were used to hold the wood in place while the glue cured. In between each 2“teak plank was a ¾” teak retainer strip that held the larger planks in place. The 2000 screws went through these retainer strips into the deck. Some of the screws eventually leaked allowing about 40% of the balsa core to become moist.

All 2000 screws were removed and each screw hole was carefully sealed from above. The deck was also dried and sealed from below. The ¾“teak retainer stripes were thrown away because the planks were firmly glued to the deck. Black silicone deck sealant replaced wooden stripes. Notice the wide caulk seams in the photo.

Note, the teak retainer strips and screws that were discarded. Because the deck was firmly glued in place the strips had no purpose.

In the photo below the retainer strips and screws have been removed and the remaining grooves have been partially filled with West epoxy. Also each screw hole was individually injected with epoxy.

Although none of the main deck was rotted, a perimeter of rot existed around each through deck fitting. Here up to a 7” radius of balsa core was removed using a special tool. Polyurethane was injected to replace the lost balsa. The fiberglass laminate was not disturbed. See the sections on balsa core rot and balsa core moisture problems for details on the repairs.

The deck was re-caulked with a silicone base product from Teak Decking Systems. Silicone was selected because it is almost 100% resistant to UV light. Because of the unusually wide seams over $2500 in caulk was used.

The finished product should last for years. Not 1 wood screw exists in the deck.
