POLYMER GLOSS VARNISH
Mixed with Derivan colours, it increases gloss and flow characteristics. Used as a finishing varnish, it produces a strong, protective, tack-free, clear film.
Available in 250ml, 500ml and 2 Litre sizes.
As acrylics dry very rapidly, care should be taken to apply varnish pre-diluted with water (as per directions on labels). Polymer Gloss Varnish applied in very thick layers on a hot day could trap moisture, resulting in a cloudy film which would be very difficult to correct, e.g. all Derivan painting mediums are freely intermixable - Polymer Gloss Varnish will intermix with Spreader Medium to give a glossy glaze effect (however, do not mix turps varnishes with other mediums). Nevertheless, painters are advised to use some discretion in pre-determining their selection of mediums to avoid unwanted effects.
Pictures treated with Polymer Gloss will appear to look like work done with oil paints or shiny enamel. Polymer Gloss Varnish is freely intermixable with Derivan Acrylic.
It is water-based and may appear slightly milky whilst wet. This is an optical effect produced by light refraction of acrylic particles suspended within the water-based film. The effect disappears when the film is dry.
