An aerosol varnish designed to preserve and protect oil and acrylic artwork, Winsor & Newton Professional Varnish provides a superior quality finish, resistant to blooming and cracking. What is a Varnish? Traditionally a combination of drying oil, resin, and a thinner or solvent, Varnish is a transparent liquid which dries to form a hard, protective film. Why use a Varnish? In addition to preserving artwork, and offering protection against dirt and dust, a varnish evens out the final appearance of the paint, ensuring a uniform finish. Why choose Winsor & Newton Professional Varnish? Available in Matt, Gloss and Satin finishes, Winsor & Newton Professional Varnish is perfect for use on paintings with rough brushwork, as a thinner layer can be applied than with a brush. This Winsor & Newton guide provides advice on How To Use Aerosol Varnishes. Who are Winsor & Newton? In 1832, William Winsor and Henry Newton introduced the first moist water colours to the world.
