Matt the plexiglass

Plexiglas is available in different versions. However, extremely common is clear, ie completely transparent acrylic glass. Now it happens again and again that do-it-yourselfers still have a piece of Plexiglas they need, but it should be milky (semi-transparent). As the devil wants it, but then you have only clear acrylic glass on hand. Therefore, do-it-yourselfers ask again and again whether they could not dull clear Plexiglas also. Below we give answers, if and how the acrylic glass can be matted.

More and more reasons to dull Plexiglas

At least since the LED technology Plexiglas is used more and more frequently for self-built lamps. The desired light effect usually comes only when the Plexiglas is frosted. But since clear, transparent acrylic glass is used much more often, many home improvement still have such Plexiglas at home and consider whether it can not be matted. For this purpose, the most varied suggestions are made again and again:

  • grind the Plexiglas milky (wet and / or dry)
  • grind with steel wool
  • Use orbital sander, eccentric sander, belt sander, etc.
  • grind by hand
  • Frost spray
  • Spray paint spray
  • Apply dilution
  • sandblast the Plexiglas for matting

How you matt your Plexiglas depends on the effect you want to achieve

Many of these options really work. However, there is a but: depending on which method you apply, the result is completely different. These can be desirable, but also absolutely undesirable side effects. Therefore, we describe the different matting options of acrylic glass in more detail below.

Grind plexiglas milky

To milky grind acrylic glass, you can combine different tools and tools together. Small areas can be easily sanded by hand and matted. First, use a 120 to 150 grit. Then in the second sanding cycle, you go over to 400 sandpaper. In the last sanding step, matt the Plexiglas with 600 or even 800 wet sandpaper.

However, the larger the surface, the less accurate the result will look later. You can avoid this if you use an orbital sander or orbital sander instead. However, the sandpaper used must again have a correspondingly fine grain size.

For tubes and other round Plexiglas bodies (rollers), it would even be preferable to clamp the body in a lathe and then dull accordingly with vibratory or belt sander. If, on the other hand, matting is to be given a somewhat uneven texture that can also go a little deeper into the acrylic, you can use steel wool.

Dilutions (acetone), paint spray and frost spray for matting

Even with this Plexiglas can be matted. However, you will achieve very special results: streaks will form on the Plexiglas surface. The frost spray will, in combination with water, even contract into abstract forms.

So you can apply either thinner or spray paint spray. The paint is simply removed after drying with an adhesive tape. In both cases, the thinner attacked the acrylic glass. It is dull, but mostly stingy.

Sand plexiglas for matting

Sandblasting Plexiglas is by far the best method of matting. They achieve a uniform effect. By using different fine grains of sand you can structure the surface more or less rough. Particularly hard acrylic glass can also be frosted with glass beads. With conventional, fine grains of sand, this can take a perceived eternity for very hard Plexiglas.


So there are quite a few ways you can dull Plexiglas. However, you should keep in mind that the technique used in each case is preferably suitable for either very small or very large areas. You can also influence the type of structuring.

Tips & Tricks

You can, of course, depending on the subsequent use, also attach a frosted film on the Plexiglas.Beim sawing Plexiglas and other processing methods may be that the Plexiglas is unintentionally matted. But even with the targeted matting of the acrylic glass, it can, as mentioned, come to irregularities. In such cases you can polish Plexiglas. Even very dull Plexiglas surfaces become transparent again.
