Atelier Acrylic Medium - Fast Medium/Fixer

This is the first time i have used the fast medium fixer. I really like it. I wasnt entirely sure how it works or what it does. So heres the deal. Apply ontop of a layer of acrylic paint that you dont want the next layer to affect. So say youve done a back ground. Apply fixer the add a tree. But you stuff up the tree and want to water off a branch. Without fixer youd pull off the background colour..Its also fab under varnish. Chefs kiss

Applies easily and protects the paints between layers. Protects the paint from smudging, a must before varnishing. :) Good pricing.
