Liquitex Permanent Matte Varnish (Flexible Surface) is used as a final matte varnish over acrylic paintings on both flexible and rigid supports. Produces a non-glare, low sheen surface that will intensify colors. This low viscosity varnish dries to a non-tacky, hard, flexible surface that is dirt resistant. Flexible, archival, non-yellowing and water resistant when dry. Depending upon substrate, allows moisture to pass through (breathable). For interior use only.
