Golden Acrylic Medium, GAC-100 Universal, 16 Oz

i paint on wood panels and have found this to be the best sealer before geso.is another step but wort the time and efort.

Great product for priming raw wood panels. Love this stuff!

Works well for thinning acrylics and a topcoat before applying varnish. However, be aware that it leaves a VERY glossy sheen, which can be dulled down with the application of a matte or satin varnish

I use this product to under prime wood panels/composite boards. It keeps the acids from seeping through. I dont think anybody can go wrong with Golden.

Love this product! I use it as a base any time I am painting on raw wood panels.

Worked beautifully to seal a wood panel before applying gesso and painting. Great product.

Used on acrylic artwork.

Excellent quality. Does what it is advertised to do. Golden is a great company.

Awesome product for sealing wood items before painting.... easy clean up too and non toxic!

This helps thin out the acrylic paints without the paint peeling/chipping after the painting is done. Works very well
