How to make an acrylic glaze?
Glazing is an incredibly useful technique used in oil painting to build depth and modify colours. The same can be done in acrylic with the main difference being much quicker drying times. In its simplest form, a glaze is a thin, transparent layer of paint applied on canvas or paper, which allows the colour applied below to show through. So how do you do it?
Thin your paints with an acrylic medium such as Daler-Rowney Flow Improver. Other mediums will work just as well but the benefit of flow improver is its transparency, rather than starting white and drying clear.
With the flow improver and your colours properly mixed, apply thin layers of paint to your canvas. The higher the proportion of flow improver to paint, the more transparent your glazes will be.
Allow to dry completely and reapply as many times as desired. Multiple layers can be used to change colours as much or as little as you want, allowing for a huge amount of control without mixing lots of colours, as well as enabling smooth transitions that would otherwise be difficult in acrylic.
