This is an additive that slows drying time. If you enjoy printing but want to slow the drying time of your paint this is a great product to use.
Liquitex Paint Additives are similar to acrylic mediums in that they are mixed into acrylic paint and acrylic mediums to change consistency, thickness, transparency, sheen, drying time and absorption rate.
However, they are different in that they do not contain acrylic polymer emulsion and therefore have no binding qualities inherent in them.
Only limited quantities (usually up to 25%) of any additive can be added into the colour before harming the paint film.
