For more than four decades, Sika continues to sponsor the 2026 Sikaflex® Challenge Build-a-Boat Cup series. These exciting competitions challenge contestants to design, build and race small boats using plywood and lumber, zip ties and fast-curing Sikaflex®-291 adhesive & sealant to keep their watercraft afloat.
