Poly(methyl methacrylate) (PMMA), known by the trade names Crylux, Plexiglas, Acrylite, Lucite, and Perspex is among several transparent thermoplastics often used in sheet form as a shatter-resistant alternative to glass. PMMA is an excellent choice for acrylic painting. No size or ground is needed.
Prepare by cleaning with mild soap and water. Light abrasion may be necessary to improve adhesion.
For work in oils, watercolors, and dry drawing media, applying an acrylic ground, gel, or paste is recommended to alter the surface’s absorbency and/or texture.
