Acryl Med 32 Oz Gac-800 Acrylic White

Great addition to my art pieces

It’s one of the best products out there. No cracks in my art.

I add this to my paint mixture as part of my pouring medium. It works very well and has good consistency. You don't need much so it's a great value for the price.

Gac 800 works great as a medium to add to acrylic paints. The consistency makes it easier to mix and it does get the paint a little more shine. It can drag quickly, but if you put it on thick, we know it takes a little longer.

This is very much a necessary medium to add to my paints before I pour or paint, as living in the dry climate of Utah. It prevents the layers from drying at different rates which causes some deep cracking or rutty appearance that ends up ruining a composition. Paint isn't cheap so it is a necessary investment when it's almost a guaranteed waste, without it. This does not change the color of your paint. It's consistency is thick enough to evenly dispurse mica pigment powders before mixing them with another medium with binders, providing the rich, vibrant color with no dulling of sparkles.

I bought this product to add to home-made acrylic "paint-pouring" mixtures. It is supposed to help reduce the chances that your paint will "craze" or crack. Ideal paint-pouring mixtures don't change the color of your paint, they make it more fluid, but they don't reduce its opacity or break down its adhesion either (the way simply diluting the paint in water would). There are pre-made paint-pouring mixtures out there that I have tried (and personally I have not found the higher-priced Liquitex brand especially better than the cheaper Sergeant Arts brand) and I have experiemented with making my own, usually based on Floetrol with other components. I heard several youtube artists recommend adding just a small amount of GAC-800, and it is important that it is a SMALL amount, because otherwise the white gac-800 does seem to make the color of the acrylic paint lighter. Of course, some acrylic-additives (such as gel medium) are white to start and clear when they dry, so it's possible that the color gets darker again when it dries, but eve if that is true, the fact that it is lighter in color while you are working with it makes it harder to decide what other colors to use and harder to know what the end result will look like. Does it help with crazing though? Probably. I have been trying to use thinner layers of poured paint (which also helps reduce the likelihood of crazing) but it's hard to measure exactly how thick the paint layer is, and I also don't always keep track of exactly how much gac I have used in every mixture of paint, so it's hard for me to pinpoint any exact reason why a certain painting may or may not end up with some crazing. If you are experiencing problems with crazing in your acrylic paint-pours, this product is worth a try, but be aware that it might lighten some of your colors. I especially don't recommend combining it with black.

Great product. A little goes a long way.

Since I started putting a good squirt of GAC in my paints, along with the pouring medium, I have not had any further cracks in my art!

Excellent performace

Ottimo +++

This product is brilliant. It really does prevent your acrylic painting cracking on drying.

A fantastic product!

Great stuff. Helps to thin the paint and reduces cracking. I used this in my acrylic pouring and it works really well.
