TEACKDECKING SYSTEMS deck caulk SIS440 was developed by professional teak deck installers over 30 years ago. The 1-component, air-moisture hardening silane-based deck joint compound is very well suited for deck joints of 3-10 mm width.
The TEACKDECKING SYSTEMS deck caulk runs very well during application and does not shrink during hardening. When hardened, it is easy to sand, extremely flexible and highly resistant to UV light. A primer is not recommended for teak deck caulking. However, the joints must be well sanded and cleaned with acetone. An inlay masking tape is recommended to prevent 3-flank adhesion.
