Gyproc Joint Filler Multipurpose is a gypsum-based setting compound for bulk and secondary filling of plasterboard joints. It is used in the traditional three-stage jointing process to embed paper tape and build up filled joints before the finishing coat.
The mixed material remains workable for approximately one hour. Each coat should be allowed to set before the next is applied, with a minimum setting period of 140 minutes before the finishing coat.
This 12.5kg bag provides an average coverage of approximately 37m² for professional internal drywall jointing.
