The compatibility of acrylic glass with other materials

The technical name of acrylic glass is polymethyl methacrylate (PMMA). But also under the brand name "Plexiglas" it is common. If you want to paint acrylic glass, it is the special chemical properties that are important at first. Thus, acrylic glass does not tolerate all the dilutions that exist. Acrylic glass with the following substances is well tolerated:

  • Gasoline (benzene-free)
  • Benzine (benzene-free)
  • isopropanol
  • oils
  • acids
  • Lye of medium concentration
  • basically inorganic compounds

Paints may not contain any contents with the following substances

For other fabrics, acrylic glass is either damaged or dissolves:

  • Hydrochlorofluorocarbons
  • acetone
  • alcohol
  • benzene
  • namely dilutions like nitro dilution
  • basically organic compounds

The different painting techniques for acrylic glass

So you do not accidentally resort to a paint containing incompatible solvents, you should use 2-component water-based acrylic paints. Beforehand, the prepared acrylic surface is provided with a suitable primer. When painting, the choice of the suitable paint also depends on the painting technique:

  • To brush
  • Rolls (foam roller)
  • Spraying (spray painting, airbrushing)
  • Spraying (spray can)

What kind of paint should be used

In addition, the effect that you want to achieve is important. For example, a surface structure, completely opaque colored lacquer, metallic paints, slip-resistant or with certain electrical conductivity properties.

Step-by-step instructions for varnishing acrylic glass

  • suitable lacquer (for example 2-component water-based acrylic lacquer)
  • suitable primer, optionally colorless
  • possibly a seal
  • Sandpaper (wet, dry, in different grain sizes)
  • Microfiber cloths for cleaning
  • Adhesive tape (polyester)
  • sanding block
  • sander
  • Painting tool (brush, roller or spray gun and compressor)
  • respiratory protection
  • If necessary, radiant heater for drying the paint

1. Preparatory work

First, the acrylic glass must be sanded. Use a finer and finer grain. Finally, it should be a 600 grit and wet sandpaper. Here you can find a guidebook for the professional grinding of acrylic glass: grind acrylic glass.

Then the acrylic workpiece is first rinsed with water, then cleaned with a microfiber cloth. Greasy fingerprints can be easily removed with isopropanol.

2. Priming and painting

Now you can prime and varnish the acrylic glass in your preferred technique. Regardless of the technique, you must always make sure that the primer or varnish that has already been applied must first dry completely before proceeding to the next work step.

3. Sealing the varnished acrylic glass

Finally, you can still seal the acrylic glass. Since mostly solvent-containing products are (must) be used, pay attention to a compatibility with the acrylic glass.

Tips & Tricks

Of course, the type of paint also depends on the requirements. However, especially with transparent acrylic glass, interior painting also lends itself to numerous applications. The colored lacquer is visible through the transparent acrylic glass, which causes a special effect. When using primers, make sure that they are neutral in color and transparent - otherwise you will see the color of the primer.

There are numerous processing options of acrylic glass. Before you paint acrylic glass, you may be able to make it special on the edges by its refractive properties. So you can pour acrylic glass. You could also pour LEDs into the acrylic glass to be painted.
