Protect working areas in plastic before use. Powertex works best with natural fabrics such as cotton, silk, linen. Once Powertex has been rubbed into the fabric fibers, the fabric can be draped and shaped and left to harden. It will be completely dry within 3 days and weatherproof enough to go outside in three weeks.
Powertex must be kept away from frost in its unused state, so please store containers above 5 degrees.
