U.S. Art Supply Acrylic Retarder Acrylic Medium, 200ml Tube - Mixed with Color Gives You Longer Working Times

Great for extending acrylic drying time if you need a little more time when working on an art project. Excellent to have on the art desk. Carol from Comox

Good price, works. I live in a dry climate so I find it helpful. I actually find this medium very helpful for blending acrylics as it allows me to treat them more like oils. I think that I may be in search of a more potent paint retarder that will keep paints wet without diluting them so much, but generally I am very happy with this and will purchase it again.

Totally upped my acrylic painting game! And this tube will last me a long time, 'cause it takes very little to do the trick.

It comes with hardly any instruction and I'm just learning how to paint. I tried a little and tried alot. I finally found a video and mixed it with white paint and water, still dried very quickly.

Works great. Expensive for the size, but works.
