DecoArt Americana DuraClear Matte varnish, 59ml (ref. DS60-3), is a water-based polyurethane varnish that forms a transparent, flexible, and completely matte protective film on hard surfaces. Its permanent, anti-reflective, and non-yellowing formula protects paintings on wood, MDF, ceramic, and plaster from weathering, both indoors and outdoors. It is the essential liquid varnish for brush application, perfect for sealing and giving a matte finish to craft projects.
