It gives a matt finish which increases the density of the colours. You can mix Matt Gel Medium with Gloss Gel Medium to create a satin finish.
Pebeo Matt Gel Medium can be thinned with water if necessary, is non-yellowing and translucent after drying. The trying time of Matt Medium varies depending on how thick it is applied (quick drying for thin layers, several hours for thick applications).
