How To Properly Prepare & Re-Caulk a Teak Deck Seam — Part 1 of 2

An earlier cut of our re-caulking Part 1 guide. Step-by-step instruction on seam prep, bond breaker tape, and professional caulking technique from TDS craftsmen. This version of the tutorial provides a comprehensive walkthrough of the preparation phase — the most important stage in achieving a long-lasting, watertight caulk seam.

For our updated two-part series with additional detail on tooling and finishing, see the links below. Both guides use TDS SIS 440 caulk and cover the same fundamental technique.
