Sikaflex® 291 is a 1-component, polyurethane elastomeric adhesive, and sealant. Its fast cure time makes it ideal for applications where speed is important. It has excellent adhesion to gel coat, fiberglass, metal, and wood. It may be squeezed or brushed in place. Sikaflex® -291 can be overpainted after the product is tack-free and can be sanded after full cure.
