Product Description

Professional Deck Caulking Compound

Sikaflex®-290 DC PRO is a 1-component, polyurethane-based joint sealing compound, specifically formulated for caulking joints in traditional timber marine decking. It exhibits excellent weathering resistance and is therefore well suited for highly exposed open joints within the maritime environment. The sealing compound cures to form a flexible elastomer which allows a fast and easy sanding process.
Sikaflex®-290 DC PRO meets the requirements set out by the International Maritime Organization (IMO).  


Sikaflex®-290 DC PRO is designed for caulking of joints in traditional timber decking for boat-, yacht and commercial ship constructions.
