Galeria Matt Medium will give a matt finish and also maintain the consistency of the colour whilst improving flow and transparency. Colours will remain usable slightly longer when mixed with this medium.
Bought a similar 'own brand' product a year ago from a different supplier. It turned into an unuseable solid over the winter. No more cheap substitutes for me! Philip Cram (Workington, United Kingdom) on 9 Apr 2013
Perfect for adding to paint instead of water in limited amounts, and produces good glazes, and a great price. David Molloy (Rossendale,, United Kingdom) on 18 May 2012
