GOLDEN Acrylic Matte Medium 473 ml — 100% Acrylic Extender that Reduces Gloss & Preserves Colour

GOLDEN Matte Medium is a 100% acrylic polymer emulsion that lowers gloss and extends acrylic colour without altering pigment strength.

This 16-ounce bottle of GOLDEN Matte Medium is designed to modify the surface sheen of acrylic paints while preserving colour vibrancy and adhesion. It blends cleanly with acrylics to create a satin-to-matte finish, thins with water for flow control, and can be used as an extender or mixing medium in layers and glazes. Note that it is not formulated to replace a final picture varnish.

How will this medium change the look of my acrylic paint?

Mixing GOLDEN Matte Medium into your paints noticeably reduces gloss and creates an even, low-sheen surface without dulling pigment intensity. It allows you to control reflective properties across a painting and helps achieve consistent matte areas.

• Reduces surface sheen while preserving colour saturation
• Produces an even matte or satin finish depending on ratio
• Useful for eliminating unwanted glare in finished works

How do I use it in mixes, glazing, or to extend paint?

Use the medium straight from the bottle or mix it with acrylic colour to increase body and working time without weakening pigment. For glazing, combine with small amounts of water to increase transparency; for extending, replace part of the paint with medium to cover more area.

• Mix 1:1 with paint for extended coverage and lowered gloss
• Add a little water if you need greater flow or transparency
• Layerable—compatible with subsequent acrylic layers once dry

Is this product suitable for final protection or varnishing?

No—GOLDEN Matte Medium is not intended as a final picture varnish. It functions as a working medium and a modifier for sheen and handling; for long-term protection and removable varnishing, use a dedicated varnish product after the painting is fully cured.

• Not formulated to replace final varnishes or UV-protective coatings
• Compatible with most acrylic varnishes when used as part of a finished process
• Allow layers containing the medium to cure before applying a varnish

How should I store and thin GOLDEN Matte Medium?

Keep the bottle tightly sealed and store it in a cool, dry place away from frost and direct heat. To thin the medium or paint mixtures, add clean water sparingly; heavy dilution can reduce film strength and coverage.

• Seal cap after each use to prevent skinning or contamination
• Thin with water for flow—avoid excessive dilution
• Stable for long-term storage when kept in recommended conditions

Who this is for: Artists, illustrators, and mixed-media makers who need reliable control over paint sheen and working properties will find GOLDEN Matte Medium valuable. It's ideal for painters who want to extend acrylics, flatten glossy spots, create glazes, or temper varnish-like reflections during layering—without altering pigment performance. If you require an actual protective varnish or UV filter, plan to finish with a dedicated varnish once your piece is fully dry and cured.
