How to use it Can be thinned by diluting with up to 25% water - distilled water will give best results. Mix as much as you like into acrylic color to create the viscosity and transparency you want - the more you add, the thinner and more transparent your color will become. If bubbles appear when stirring, leave to sit while they rise and disappear. This is semi-opaque when wet, transparent when dry. To fix pastel, graphite or chalk, mix 1 part medium to 1 part distilled water and apply with an atomizer or airbrush. Apply with a brush/sponge as a lightweight collaging glue. Fully compatible with all Liquitex products
