Re-caulking the deck is an essential operation to deal with in the life of a vessel. The constant wetting and drying and the foot traffic to which a yacht’s deck is exposed to might require removing the existing caulking from the seams and replace it. Especially if the deck gets to be so worn out to an extent that the caulk in the seams is too shallow to be effective. Another reason that may cause the deck to worn out is the exposure to maximum UV rays from the sun, which can be very harmful to the caulk.
