Derivan Matisse MM7 Polymer Gloss Varnish

Matisse Polymer Gloss Varnish & Medium serves both as a gloss finishing varnish and as a glossy additive to the paint. The use of this varnish will help maintain colour intensity with a gloss finish comparable to that of oil paintings

Mixed with Matisse Colours, it increases gloss and flow characteristics. Used as a finishing varnish, it produces a strong, protective, tack-free, clear film. MM7 Polymer Gloss Varnish and MM6 Polymer Matt Varnish are freely intermixable to achieve a semi-gloss or satin finish.

MM7 dries completely clear, is non-yellowing and it will remain totally flexible. Polymer water-based varnishes may appear to be slightly hazy whilst in solution. This is an optical effect produced by light refraction of acrylic particles suspended within the water-based medium. The effect disappears when the film is dry.

Further Information

• As acrylics dry very rapidly, care should be taken to apply varnish pre-diluted with water (how much water will depend on the temperature, humidity and how thickly you apply each coat, however, a good starting point is somewhere between 10% to 20% water to medium with a maximum of 50%). Polymer 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.
• All Matisse painting mediums are freely intermixable, e.g. Polymer Gloss Varnish will intermix with MM6 Polymer Matt Varnish to give a subdued gloss effect; MM8 Spreader Medium will intermix with the above to offer various degrees of water resistance and flow.
• Drying time will be approximately 1-2 hours, depending upon weather conditions.
• Do not attempt to speed the drying process with a heat source such as a blow dryer or fan heater, as this may cause cracking. 
• Do not use over oil paint
• Do not allow to freeze.
• MM7 Polymer Gloss Varnish and medium is also an archival adhesive and most suitable replacement for PVA glues which will yellow and go brittle in a short period of time.
