It’s always nice when a product works BETTER than you expected!
A few months ago, I was experimenting with doing a collage on a terracotta or saltillo type floor tile as the support. I decided the tile was too heavy to be practical and abandoned it.
But, I had already sealed it on all sides and edges with Golden paint co’s GAC 100, an all purpose acrylic medium that is also a good sealer. I’d also already adhered parts of an old vintage magazine page in a way that would look aged and peeling. I then sealed all of it with GAC 100, and left it on the patio for months, while I thought about whether to do anything more with it.
Once I decided it was just too darn heavy and would require too much futzing around to hang it safely, I decided to turn it into a stepping stone by the water hose. I laid it face down in the perpetual mud there, and fully expected the bits of magazine page would come off if or when I ever got around to lifting it to check. Well, it was laying in mud, water, and 110+ sun and heat all summer so far, and I decided to turn it over this weekend.
To my GREAT surprise…it was completely unaffected by the sun, heat, and long mud bath!
The GAC 100 held up in every way. I feel confident now that it must be a pretty durable product, and it’s what I have been using to seal the wood scraps, etc, that I’ve painted on to do some of my ‘recycled art’ like the ‘Recycled Rooster’ on an OSB scrap, and the painting, ‘Good China in the Bad Desert’ which is on a scrap of hardboard. I also use it as a painting medium sometimes, as I believe it dries a bit slower than regular acrylic gel or fluid mediums. It does not seem brittle, which is often a trade off for really durable clear acrylic products, but it is probably not quite as plastic when dry as, say gel medium.
GAC 100 dries clear and glossy. As with the above mentioned paintings on lumber store scraps, I have used it as a sealer on surfaces I think might need sealing, before I gesso them, or sometimes just the GAC 100 if I want the surface to show through. (If I want the end result to be matte, I coat the final work with fluid matte medium, instead of a glossier acrylic varnish/medium or more GAC 100.)
BTW this is not any sort of official endorsement. I shared this blog with Golden on their Facebook page and they seemed happy to know about this experience. I was not paid by Golden, and I am not guaranteeing you can soak your art in mud and expect the same results. 🙂
