A laser spray is a spray that you can spray on your material before marking/engraving. The spray turns your engraving black / dark gray and can provide a nice contrast to your material. You do not use spray if you are going to engrave, for example, wood or plastic (acrylic, PE, etc). You use the spray for metals and, for example, glass and ceramics.

Metal

The use of a laser spray is necessary when engraving / marking metals. Without using a laser spray, you cannot mark/engrave metals. If you do, the laser beam reflects back to the laser source, causing it to malfunction. Engraving/marking a metal without the use of a laser spray also voids the warranty on the laser source, if it is actually still under warranty.

Non-metals

When engraving glass, ceramics and porcelain, for example, laser spray can be a nice addition. It is not necessary to use it with these materials. If you engrave these materials without using a laser spray, the engraving will blend out a bit. For example, if you engrave glass, the engraving will be somewhat whitish and fairly dull. From a distance, the engraving is actually not that visible. If you use a laser spray, the engraving becomes black/dark gray and is immediately noticeable because there is a nice contrast between glass and engraving.

Various sprays

There are various laser sprays. We have 4 in our assortment that all leave a black / dark gray semi-permanent engraving. The difference in the sprays is the material they can be used on.
