SikaBiresin® AP077 White Quart is a high-performance polyester filler and fairing compound designed for repairs at or near the surface of boats and composites. This formula is intended for above and below-waterline applications and requires the BPO hardener for cure. It creates a smooth, workable paste that cures quickly to accelerate repairs or finishing tasks.
Easy to work with and easy to sand, AP077 can be finished to a feather edge, reducing the need for heavy blocking and leaving a seamless surface ready for coatings. It applies smoothly with a squeegee, spatula, or flat tool, and once cured, will accept virtually any coating or decorative film.
