Choosing the Right Thinning Method for the Job
Washes and underpainting
Water works well for thin toned grounds and loose underpainting, used in moderation.
Glazing
Glazing medium makes transparent layers while keeping the binder strong.
Fine lines and detail
A flow improver or airbrush medium makes paint flow off fine brushes without losing opacity.
Pouring
Pouring medium creates fluid paint that levels and holds colour separation, and prevents cracking.
Test first
Try your mix on scrap to check flow, coverage and drying before using it on a painting.
Storing Thinned Paint
Thinned acrylic mixes keep for a while in small airtight jars, which saves remixing a colour for a series of glazes or a pour. Label each jar with the colour and the ratio you used, stir before reuse, and discard any mix that smells sour or has separated into lumps.
