Painting Surface
Plexiglass
Plexiglass is a rigid acrylic sheet with a smooth, nonporous surface and sensitivity to incompatible solvents that can craze or damage the material.
Paint compatibility with plexiglass
Acrylic paint is suitable for decorative Plexiglass, while other paints need solvent compatibility checks to avoid crazing or damaging the acrylic sheet.
| Paint | Compatibility | Preparation | Primer or ground | Finish | Guide |
|---|---|---|---|---|---|
| Acrylic paint | Good for decorative use | Remove dust, grease, and dirt with acrylic-safe cleaning methods; paint directly or lightly roughen the surface when the desired finish and product allow it. | Usually optional for decorative work; use an acrylic-compatible adhesion primer when the selected system requires one. | Use a compatible clear finish only when the project needs additional protection. | — |
| Glass paint | Good with an acrylic-compatible formula | Clean with an acrylic-safe method; paint directly or lightly roughen when appropriate. | Usually product-specific; use only primers approved for acrylic sheet. | Follow the paint's curing instructions and avoid solvent-heavy finishes that can attack the acrylic. | — |
| Oil paint | Good with a compatible formula | Clean the acrylic sheet with products approved for the material and test the paint first, especially when thinners or other solvents are involved. | Product-specific; avoid primers or thinners that can attack acrylic sheet. | Allow the paint to cure fully and keep incompatible solvents away from the finished sheet. | — |
| Spray paint | Formula-specific | Use clean, dry Plexiglass and test the exact aerosol on scrap or an inconspicuous area because some spray-paint solvents can craze or etch acrylic. | Use only a primer or bonding system explicitly compatible with acrylic sheet when one is required. | Apply light coats and follow the full drying and curing schedule before handling. | — |

Painters who used plexiglass
These records document paintings and light works made with Plexiglas or acrylic sheet, including examples where paint is applied directly to the panel.

Mary Corse
For Untitled (Space Plexi + Painted Wood) (1966), Corse combined plexiglass, painted wood, and light in an early light encasement. The Whitney describes plexiglass as one of her painting materials, part of her investigation of perception through light and reflective surfaces.

Roy Lichtenstein
Lichtenstein’s Sea Shore (1964) uses oil and acrylic on two sheets of Plexiglas, as the Whitney records. The paired transparent panels carry a dotted blue seascape in a shallow, dimensional format, and the museum classifies the work as a painting.

Craig Kauffman
Norton Simon identifies Kauffman’s Untitled (1968) as acrylic lacquer on vacuum-formed Plexiglas. He sprayed color over the molded sheet, using its shallow ridges and curves to carry an abstract composition as a shallow wall relief.
