Sikaflex 290-DC PRO is designed for caulking of joints in traditional timber decking for boat-, yacht and commercial ship constructions. Please use this teak joint sealant in combination with the corresponding primer: Sika primer 290-DC.
We advise to place "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 caulk expansion and contraction. You can use fineline tape for this, for example. Apply the sealant with a caulking gun and ensure a convex finish, Sikaflex will shrink a little. After three days, excess sealant can be sanded away and you can fill air bubbles again.
