STOPGAP FILL AND PRIME is a two-component, fast drying, flexible cement based primer that is designed to fill and prime joints in raised access panels quickly and easily. Its formulation gives it a thixotropic consistency, which enables it to fill joints up to 4mm wide in raised access panels. When applied up to a thickness of 1mm, it sets rapidly and is ready to receive foot traffic from 60 minutes. This quick turnaround time allows floor fitters to complete projects to a high standard with minimal downtime.
