Sikaflex 291 Adhesive Sealant, White - 367g/300ml Cartridge

The product featured faster cure (than 4200) and superior adhesion to damp wood.
With temps in the 70s, product was terrible to push out of tube. Needed extra effort and leverage, which was extremely difficult under a boat!! Two days later, plastic nozzle of the tube, full of sealant, was NOT cured! This is not good...... Sealant MUST cure in 8 hours max, for critical uses like a wood boat hull, going in the water a day after caulking structural seams!
