Open acrylic gloss medium - 8 oz

Golden

$24.99

In stock Low stock Unavailable

Open Acrylic gloss medium is formulated to a lower viscosity than OPEN Acrylic Colors and is used to maintain properties when a more fluid mixture is desired to increase flow.

Mix any quantity of gel or medium with Open acrylics in order to extend the paint or modify its sheen, viscosity, or transparency.

The joy of Open acrylics and mediums is that they can be worked for extended periods of time which is excellent for blending, getting clean edges, and for detail work.

Throughout the painting process, the paint viscosity will pass through several stages: at first it will be as it comes out of the tube, and the paint tack will slowly increase, in which case subsequent applications of any Open products or water can continue to reopen layers and allow the artist to continue blending.

The Open series are best used in thin layers. Applications of more than 1/16 will result in: excessively long drying periods, persistently soft, higher tack feel, and translucent layers that remain cloudy. If it is necessary to apply paint in thick layers, it is recommended to use Golden Heavy Body acrylics.

Available in this series:

Golden Open Thinner: multipurpose thinner and retarder.

Golden Open Gloss Gel: has the same viscosity as the Open paints.

Ultra Gloss Varnish 1.39L

Liquitex

$109.99

In stock Low stock Unavailable

Liquitex high gloss varnish enhances the intensity, transparency and luminosity of colours. It protects and improves the fluidity of paint and its adherence to supports. Of medium viscosity, it becomes transparent upon drying, stays smooth and does not yellow. Important information : For interior and exterior use. The permanent varnishes are irreversible and must always be tested before being applied. The painted surface must be completely dry (between 72 hours and 2 weeks, depending on thickness) before applying the varnish. Shake the varnish before use. For a better result, shake the varnish the day before and let it sit in order to avoid the formation of air bubbles when applying. The varnish can also be mixed gently with a stick before use in order to prevent the formation of bubbles. Apply 1 to 3 light coats, instead of one single thick coat. A thick coat will take longer to dry, may run or sink in during application and may result in visible paint marks when dry. Lay the work to be varnished flat on a table. Do not dilute the varnish as it will then be more likely to produce air bubbles. Use : Can be mixed with acrylic colours to thin out the colour or to create glossy glazes. Supports : suitable for all supports. Drying time : 3 to 5 days with acrylic. Let dry for 3 hrs between each coat.

Acrylic mediums let you push your paint beyond its standard behaviour. Mixed directly into acrylic paint, they can slow drying time, increase transparency, build thick impasto textures, add gloss or matte finishes, and much more. DeSerres carries a wide selection of acrylic mediums from leading brands, suited to every technique from fine art painting to mixed media and experimental work.

Which Acrylic Medium Is Right for Your Technique?

Gel mediums thicken paint for impasto work and can be used as a collage adhesive or texture builder. Glazing mediums increase transparency and extend open time, ideal for layering and colour blending. Retarders slow drying time, giving you more time to blend and rework wet paint. Flow improvers reduce surface tension for smoother, more fluid application. Matte and gloss mediums adjust the sheen of your finished surface. Choosing the right medium depends on the effect you want to achieve. Explore our Acrylic Paint, Primers and our full Mediums, Varnishes & Resins collection for more options.
