Task C-10 Repairs plastered surfaces and restores textured surfaces and mouldings
Task Descriptor
Drywall finishers and plasterers repair and restore plastered and textured surfaces to restore them to the original look. New installation of these materials is not common, but the repair and restoration of existing installations may still be required.
Drywall finishers and plasterers may restore old mouldings on historical buildings. Replacement mouldings are typically created by manufacturers and then installed by drywall finishers and plasterers.
