Hey, have you ever wondered if you can actually spray paint glass? I mean, I know I have! I always thought it would be cool to spruce up a plain old vase or some glass decor. But, the real question is, how do you even go about painting on a curved surface like glass?

What Type of Spray Paint Is Best for Glass?

If you believed that any sort of paint would work on glass, you are not alone. After all, in our daily lives, glass is generally transparent, yet there are circumstances when it must be coated in paint, such as during crafting and window staining. The table below summarizes the paints that produce an excellent visual impression after being applied to glass and how they look once done.

Type of Paint Appearance/Effect on Glass Surfaces
Enamel Paints (oil-based and other) Gloss, opaque, clear, smooth, resistant to scratches
Acrylic Paints (clear and color) Clear, transparent, stained glass effect, resistance to scratches and friction
Oil Paints Smooth, intense color, waterproof, sheen finish
Solvent-Based Paints Smooth, muted color, smooth texture, protects against minor scratches and UV damage

You can also use an airbrush instead of spray paint. To find the right paint, you will need to read my guide.

Do You Need a Primer When Applying Paint to Glass?

Spray paint on glass is typically compelling enough, although a primer is recommended if you want a smoother overall look and texture. However, this does not rule out the need for priming when using spray paint on glass.

Whether using spray paint in a can or store-bought paint with a powered paint sprayer, these paints are typically effective on glass if the surface has been prepared correctly.

Oil- or acrylic-based paints are the most common paints used on glass. This does not imply that any paint you apply to glass surfaces will have the desired effect; instead, most paints sold in cans or for use with paint sprayers are oil- or acrylic-based, making them suited for coating glass.

When applying spray paint to glass, a primer will make it adhere to the surface considerably more accessible, especially if the glass has been properly prepped. Unfortunately, glass is a “sheer” surface, which implies that coatings won’t stick well to it. In contrast to surfaces like wood, metal, and ceramics

When it comes to glass surfaces, however, you should exercise caution while applying spray paint.

How To Spray Paint Glass Effectively

This thread is intended to teach you how to paint glass successfully, from start to finish, whether this is your first time attempting it or not. Here’s a step-by-step tutorial on preparing your glass workpiece for painting and applying the paint effectively with minimal mistakes, splatters, double efforts, and (in the worst case scenario) breakage.

Ensure That Your Glass Is Clean

Glass, as we’ve previously said, is a transparent surface with the primary purpose of preventing things from adhering to it. Consider your house’s windows or your automobile’s windscreen – water and other thick liquids readily roll off them, even though drinks have an easier time sticking to them. To summarize, cleaning your glass workpiece with soapy water and removing little pieces of debris, dust, and scratches that have become filled with filth is the first stage in the preparation procedure. Allow sufficient time for the glass to dry thoroughly after washing.

Cover Contact Surfaces

Glass is one of the most frequent materials we employ for storage containers in our homes, so our hands and mouths touch these surfaces regularly. As a result, it’s critical that you cover or tape exposed places on glass working components that will come into contact with any sensitive spots on your body.

A drinking glass, for example, has a wide lip. Simply stick some tape in strategic locations to prevent primer or paint from contacting your mouth in the future.

You may also cover any surfaces you will come into touch with while priming your workpiece to ensure that nothing gets on your hands should you need to move the workpiece during the priming process.

Rub Down with Liquid Spirits

Rubbing down your glass with some liquid spirits, mainly if you’re using oil-based paints, can assist the adhesion process. You might perform this in one of two methods: submerging the glass workpiece in a shallow container of liquid alcohol and rotating it or wiping it dry with a clean cloth.

When working with liquid alcohol, remember that you may become disoriented if you breathe it in large quantities. When drying your workpiece in direct sunlight, place it there to ensure that all of the spirits evaporate completely.

Apply Primer

We previously stated that primer on glass is unnecessary, although if you have the choice, you should know that it will improve the application process and enhance the paint’s finish when dried.

Your primer may be alcohol-based, implying that the previous step says you should use alcohol to prepare your surface, but this is only because it’s a coincidence. Always check with the manufacturer’s instructions for preparation before loading your primer into your paint sprayer or spraying with a spray can, such as shaking or mixing it.

The goal of the technique is to apply very light and quick coats to the glass’s surface in an even, continuous manner.

The glass primer dries quickly, so work fast. Be sure to use gloves if you are going to turn the workpiece. The primer can be harmful to your skin. The workpiece will be ready to paint in about ten minutes after the primer dries.

Start Painting

When it comes to spray painting, painting, and priming go hand-in-hand. Whether you’re utilizing a powered sprayer or a can of spray paint, the skills necessary for both tasks necessitate a steady hand. You should aim to apply numerous light applications when spraying; the key to achieving this is reasonable control over your trigger/nozzle finger and proper distance management from your workpiece. Make even, smooth, continuous passes over your piece until you’ve achieved maximum coverage.

After finishing your first layer, check your workpiece for areas you may have missed or applied too much. When working with glass, it’s advisable to apply several coats – three to four is sufficient depending on how much light you want to pass through the glass – and allow three to four hours between applications to ensure that each layer fully dries. Remove any protective tape you may have used over areas where you handled the glass after applying each coat.

Apply Sealant

Apply Sealant

This step isn’t necessary because some paints don’t need to be sealed, and you may love the look and feel of your workpiece just as it is. If you’re wondering how to seal spray paint on glass, a glass sealer for various types of paint is available at most hardware shops and craft stores.

Applying sealer with a paint sprayer is unusual, and it’s usually done using the spray can (or many cans for bigger workpieces, as you can comprehend) and spreading it evenly over the piece at a safe distance to allow the sealant to dry as directed by the manufacturer.

Acrylic paints are commonly coated with sealants due to the texture formed when applied to a glass surface.

You may apply two to three coats and allow each coat to dry between applications, although the amount of time can differ based on the brand and type of sealant you use. These steps to seal spray paint on the glass will ensure that your glass workpiece has a long-lasting finish.

Tips and Tricks for Spray Painting Glass

Tips and Tricks for Spray Painting Glass

Here are some helpful hints and methods for spray painting glass. Although the process is simple, understanding the finer points of preparation and technique when it comes to outstanding projects is frequently what distinguishes the exceptional from the average. This being said, let us look at some strategies you may employ to improve the visual attractiveness of your spray-painted glass items.

Keep It Clean

We mentioned this in the tutorial, but maintaining a clean workpiece and ensuring that it stays pristine until your primer is applied may save you a lot of time. It’s an awful experience to return, remove, and repaint a portion of your workpiece because some pesky particles have caused your paint to rise from the glass. Always use 100 percent confidence that your workpiece is clean and smooth before applying primer or paint.

Keep It Light

This is a fantastic tip for people who don’t want to use a primer. Painting ordinary surfaces (which have “grit”) saves you the trouble of needing to apply several coats – this is especially true with wood. When working with glass, keep the layers light and compensate by repeating these gentle applications three to four times until you are pleased with your coverage. This will also allow you to pick the amount of transparency you desire for your glass if you haven’t already done so.

Remember That This Is Still Painted Glass

Once you’ve finished your labor of love and taken a step back to admire your workpiece, it’s easy to forget that it’s still merely painted glass. Remember that even if you used one of the paints we mentioned above, it would be chipped and scuffed easily unless the glass has been baked or stained with color.

As a result, if your glass pieces will be handled or relocated frequently, one of the above coatings should be used to guarantee their durability. On this note, do not attempt to wash any spray-painted glassware in the dishwasher since the paint will peel off, and you will have paint particles.


Does Spray Paint Stick to Glass?

Yes, most types of spray paint will stick to glass. However, you may need to use a primer first for the color to adhere correctly. You should also ensure that the glass’s surface is clean before you start painting.

Can You Bake Spray Painted Glass?

Yes, you can bake spray-painted glass to set the paint. Just place your glass piece in a cold oven and then turn it on to 350 degrees Fahrenheit. Let the piece bake for 30 minutes and then turn off the oven and let it cool inside.

What Happens if You Don't Use a Primer on Glass?

If you don’t use a primer on glass, the paint may not adhere properly and could start to peel off over time. It’s always best to use a primer or base coat before applying your final layer of paint. This will help the color stay put and last longer.

Will Spray Paint Last on Glass?

Spray paint and glass are not exactly two peas in a pod. Because glass is a transparent surface with little surface friction, most materials struggle to adhere to it. Before seeing any significant decay, expect a few years of service from spray-painted glass workpieces.
