Yes. Once fully dry, we recommend sealing all Scumble applications with Artisan Enhancements™ sealers. If the Scumble technique is left unsealed it can re-open and re-activate if exposed to moisture. Note: Wax maybe used over surfaces with Scumble Glazes. To add an additional layer of wax, first seal the surface with one thin coat of Clear Topcoat sealer. After 72 hours of dry-time, additional colored waxes can be layered over the Clear Topcoat sealed surface. Follow wax manufacturer’s instructions for wax applications.
