“Liquitex Satin Varnish is my go-to when finishing an acrylic piece. It's water-based technology means it is translucent when wet and clear when dry. As a permanent sealer I use it to set work in progress when I don't want to disturb the under-painting. Liquitex Satin Varnish is low odour so is good for inside work, and prevents discolouring.”
