Winsor & Newton Gum Arabic, 75ml Bottle
Winsor & Newton Gum Arabic is a pale-colored solution that increases the gloss and transparency of watercolor paints. It can be thinned with water. Gum Arabic increases watercolor brilliancy, gloss, and transparency, giving greater depth to each color. It slows down the drying time of paint, and can also be used for controlling spread when painting wet-on-wet.
How to use:
Gum Arabic is usually mixed into the water color wash but can be added to the jar of water if you prefer to use it throughout the painting. Gum Arabic should not be used directly from the bottle because thick films will be brittle.
