Polyester Spray Filler

SK4 and SK4S are polyester spray fillers developed for model finishing and surface filling. These sprayable polyester fillers allow the application of high thicknesses in a single spraying session with multiple passes. Characterized by very low shrinkage, they are easy to sand and polish, and offer excellent adhesion on wood and laminate substrates. Compatible with all types of paints, they are ideal for professional composite model preparation and finishing.
