Can Artisan Enhancements™ Scumble be used as an extender?

Yes! Scumble can be used to extend open-times (to keep paint from drying out on larger surfaces) and as a leveler (to improve flow and help reduce brushstrokes) for water-based paints. Add 5% by volume Scumble to paint to extend. If using a Scumble + Paint mixture, allow the surface to dry overnight before recoating or sealing.
