Applications
Sikaflex-290 DC PRO is designed for caulking joints in traditional timber decks for boat, yacht and commercial ship construction. Use this teak joint sealant in combination with the corresponding primer: Sika Primer-290 DC.
We advise placing bond breaker tape at the bottom of the seam. The tape prevents an adhesive bond of the caulking to the bottom of the seam, allowing movement during sealant expansion and contraction. For example, fineline tape can be used. Apply the sealant with a caulking gun and ensure a convex finish, as Sikaflex will shrink slightly. After three days, excess sealant can be sanded away and any air bubbles can be refilled.
