Why Is Spray Paint Better For Glass?

Painting glass materials and ware are very challenging when using traditional materials. The reason for this is that it has a very smooth surface, leading to paint drips, peelings, and runs. Using brush or rollers is not very recommended, therefore. 

The slick surface of the glass does not give the paint much to adhere to. As such, paint accumulates, leading to a messy glass painting and bubbles on the surface. This makes spray painting a more convenient material to use for glass. 

What Paint Can Be Used For Spray Painting Glass?

Experts would say that any paint would stick to glass. Thus, if your only objective is to color your glass, any paint would do. The key to making it stick is to clean the glass surface thoroughly and then dry it after. 

Nonetheless, just as there are special paints used for spray painting wood, there are specific paints used for spray painting glass too. The special paints specifically designed for glass would be acrylic, enamel, and oil paint. 

As for high-end paints for glass, you can choose from either of the following: 

  • Chalk paint
  • Faux milk paint
  • Metallic finish paint
  • Matte, satin, gloss, and semi-gloss finishes

First, spray the glass with a thin layer of paint. This could act as your primer to save you time. This significantly makes the surface smoother.

Has the first layer dried for at least 15-minutes? When spraying, make sure that you are at least a foot away from the glass piece. Spray in a sweeping motion. 

The thickness of the spray paint must depend on the level of solid finish which you want to have. If you are working on a transparent piece, at least two coatings of spray paint would do.

If you are spraying paint on opaque glass, you would have to coat it with at least four layers of spray paint.
