Plastic Paint: Experimenting with Acrylics

This summer I took a leap of faith challenging myself to think about acrylic in new ways. I don’t claim expertise in this area but through trial and error I’ve learned some interesting things.

The Paint: Acrylic paint is essentially plastic and pigment suspended as a water soluble emulsion. Most acrylic and latex paints are made using a combination of acrylic or vinyl plastics. The ratios vary depending on the cost and intended use of the paint. Acrylics aren’t corrosive overtime like oil paint which, allows you to paint more directly on unusual surfaces. (Also see difference between latex & acrylic paint)

Maybe I have some unacknowledged modernist tendencies but the idea of making a painting with no support thrills me. Think of it, a painting made exclusively of paint! How much more medium specific could you be?

Acrylic Skins: An acrylic skin is simply any variety of acrylic paint or medium poured over a repellent surface, cheap thin plastic sheeting has worked best for me. Let it dry and voila you have a skin.

Other Supports: Without going too far into boring detail it turns out acrylic paint will not adhere to certain plastics…like the sheeting seen below. This sheeting is wonderful for making acrylic skins. If you want to work on a transparent surface here is what I’ve found works best.

Acrylic paint will adhere to this surface beautifully and there are no archival or clarity issues to worry about other than yellowing. (Make sure not to expose works to extreme hot or cool temperatures) You can also build panels and other shapes using acrylic solvents. These solvents are more toxic and require good ventilation. Rather than gluing pieces together the solvent dissolves the plastic creating a bond more akin to welding. The best resources for more information on this process come from aquarium professionals. Most fish tanks these days are made from plexiglas.

#2 – Vinyl – You can purchase vinyl fabric in clear and any number of other colors. Acrylic paint bonds well to this surface but evidently causes archival issues over time. Most flexible plastics contain plasticizers to keep the plastic pliable. These can degrade the acrylic paint over time.

“Vinyl materials leach plasticizers and are not typically thought of as being very archival.  These plasticizers also migrate into acrylics and in turn cause them to become sticky/tacky.”

Below are images of my experiments: (left to right)

1. Photographic image printed directly onto the acrylic skin.

2. Polyester fiber fill with soft gel medium & self leveling gel.

3. Multiple acrylic mediums and acrylic paint (3+), caran d’ache water soluble crayons all over cotton fabric.
