NCPTT has completed its study on the durability of traditional and modified limewashes. The project addresses needs of the Cane River Creole National Historical Park. The study ranked the durability of limewashes based on adhesion, abrasion resistance, and artificial weathering. Researchers tested 13 combinations that were applied in three coats to weathered wood, rough-sawn wood, handmade and modern brick, and epoxy wood filler.
NCPTT presented the results at the 2006 Traditional Building Conference.
