Liquitex Matte Gel Medium can be used to reduce shine, extend volume and thicken, while extending open time. It can also be used as a strong collaging adhesive. 

Features: 

• Reduces surface shine, increases colour depth and transparency
• Extends your colour further without affecting acrylic stability
• Increases viscosity of soft body paints, giving a thicker consistency
• Slows drying time and enhances appearance of brush marks
• Primes rough exterior walls for gesso application before mural painting
• Can be thinned by diluting with up to 25% water - distilled water will give best results
