Exterior Varnish: Spectrum Exterior Acrylic Varnish For Mural Paintings 1 Litre

Spectrum varnish is a hard, acrylic varnish for the protection of outdoor acrylic paintings and installation artwork. This milky solution of acrylic varnish will dry clear. Exterior varnish can be thinned with water. It is not graffiti proof, but will resist dirt and grime. Acrylic exterior varnish does not include UV protection but will extend the life time of your artwork beneath. Soft Satin Finish Varnish: milky fluid consistency dries clear to a durable finish 1 Litre Plastic container

Coverage: 1 Litre = 9 x 10 feet (approx 2.75 metre x 3 metre)

Recommendation:  Apply on warm dry days – ideally when there is a slight breeze to aid a steady drying speed. Make sure your acrylic paint is absolutely dry before applying any varnish.  We recommend two or three thin coats of exterior varnish rather than one thick coat (one thick coat can result in a cloudy sad finish!)

If you need UV protection use a solvent based varnish.
