Can You Use Acrylic Paints on Glass?

Acrylic paints are suitable for a very wide range of surfaces and materials – including glass. When applying acrylic paint on glass, enamel paint is best as they are durable and adhere well to smooth surfaces. Even though these paints will work well with glass, the glass will still need to be properly p[repared for painting. Make sure that there is no dirt, dust, or oils on the glass. You can also add a layer of primer to make sure that the acrylic paint on glass adheres strongly. You can also protect the paint with a sealant or varnish to help to prolong its lifespan.

As a painting medium, acrylics are water-resistant, durable, versatile, easy to clean up, and not very toxic. This makes this type of paint an attractive choice for beginners through to experienced artists, no matter what type of mediums you are using.

Painting Glass With Acrylic Paint

The big question to ask is: will acrylic paint stick to glass? Yes, acrylic paint can be used over glass. However, this doesn’t mean that it will always stick easily. For best results, a primer should be used over the smooth glass surface. This should be an enamel-based primer if using an enamel-based paint. To apply the primer, you can either use a brush or a sprayer. Let this layer dry fully for 24 to 72 hours before painting over. The primer will create a more rough surface which will help the paint to stick tightly onto the glass. Some acrylic paints are specially formulated for use on glass and won’t necessarily need a primer. Using a primer is generally a good idea though to increase the paint adhesion.

 

 

Choosing the Right Acrylic Paint

Not all acrylic paints are made equal. When choosing the right acrylic paint for painting over glass, consider your various requirements and needs for the project. Do you need a permanent solution or one that can wash off? If creating glass artwork, you will want to choose a paint that is as long-lasting as possible. Enamel-based acrylic paints are generally the preferred choice here as they are durable and have many different effects and finish options available. If you are asking the question, “can you use acrylic paints on glass?”, there are always a few considerations to make when choosing the perfect paint for your needs.

 

Transparency

The opacity or transparency of the paint is an important buying factor. This refers to how solid the color is, which is something that will affect the overall brightness. For glass, this is particularly important. Opaque colors will block out any light, and transparent ones will let the light shine through. The style you choose is a matter of personal taste.

 

Lightfastness

When paints are exposed to sunlight, the colors can sometimes fad away. This is what lightfastness refers to. A lightfast paint will maintain its pigment and will offer resistance to UV rays and fading. When painting over glass that is exposed to light, this is an important consideration.

Consistency

Whichever paints you use will need to have a similar consistency. Never mix together two paints of different consistencies, as this will result in an inconsistent painting. Test how thin or thick paint is by comparing small amounts of each next to each other. Also know that when the paint dries, paints with different consistencies produce different effects. When painting on glass, you don’t want to use paint that is too thin.

 

Finish

When the paint has finished drying it will have a unique finish. You can choose between various paint finishes to achieve your ideal final look. This includes glossy, matte, and frosted. This choice depends on the overall look and feels that you are trying to achieve. Many artists like to use a frosted finish over the glass, as glossy finishes can become quite reflective.

  • Glossy enamel acrylic paints can be used for an opaque finish or a thick coat
  • Frosted paints have a lighter and thinner coat
  • There is also a crystal gloss enamel paint that can be used to provide a combination between glossy and frosted
  • If you want to achieve a finish that is completely matte and opaque, you can use a gesso and acrylic paint combination. If painted onto a flat piece of glass, this combination will actually look like a canvas
  • Glass liner and water-based acrylics can be used for stained glass painting. Alternatively, you can use special glass paints to achieve this effect

Finding the Right Paintbrush

You may have the best acrylic paint available, but without the right paintbrush, it is useless. When using acrylics to paint on glass, there are a number of brush styles you can choose from. Each one offers its own unique painting style. We have outlined a few top paintbrush tips below:

  • Synthetic bristle brushes are not the first choice, because they can leave brush marks in the paint. However, if you are trying to achieve a more rustic look then this could work in your favor. Synthetic brushes are a good choice for doing smaller, more detailed bits of painting.
  • Natural bristle brushes offer a smoother finish that is more even. This is a great option for base coats and broad color blocks.
  • Some artists like to use sponges, as they can create a special kind of textured appearance over the glass. This look is evenly coated and slightly frosty looking.
  • Choosing the right size of the paintbrush is also essential. The size and shape of the brush will determine what kind of effects you will create, and how detailed you can paint. Go for a flat and wide brush for applying basecoats and a smaller pointier brush for finer details.

Which Glass is Best to Paint On?

Each different piece of glass has its own coefficient of expansion (COE). This is how much the glass expands and contracts when heating and cooling. This is a really important consideration for painting glass with acrylic paint, as the paint will need to have enough flexibility not to crack when this happens. If you are baking the glass piece, this is particularly important. Thick glass may be stronger, but thinner glass is more flexible. The most flexible glass with great COE is the type of glass used in dinnerware. Thick glass, like the kind used in bakeware, is not very flexible so it might crack while expanding.

Although thin glass is flexible, it is also sensitive to temperature changes. Painting on glass with acrylics at home is best done on smaller glass items, as bigger pieces will need to be baked in a professional kiln.

 

 

Materials Required for Acrylic Paint on Glass

When applying acrylic paint on glass, a couple of different materials should be used for achieving great results. The list of equipment includes:

  • The piece of glass to paint on. This could be a flat glass plane, a piece of glassware, or a decorative glass item
  • Rubbing alcohol for making sure the glass surface is properly clean. This can be applied with cotton balls or a paper towel
  • A range of different paintbrushes are good to have for achieving various effects and levels of detail
  • A paint palette for mixing the paint on
  • A design, stencil, or pattern if you are using one as a template
  • The acrylic paints. Try to use enamel or glass paints as these are formulated for use on smooth surfaces like glass. They offer a durable finish and great coloring
  • Acrylic medium. If you need to thin down the paint’s consistency a bit, use a clear acrylic medium. We do not recommend using water for this because glass is not porous
  • A glass outliner if you want to achieve a stained glass effect
  • Glass paint markers for small details or for writing with
  • You may also want to use a sealant or varnish. This makes them last longer and protects the paint. If your painted glass is being used with food, make sure that the sealer is labeled as being food safe

 

 

Painting on Glass With Acrylics – Tutorial

When painting acrylic paint on glass, there are a number of different methods you could take. You could paint freehand, or follow a stencil design. All you really need are brushes and some sponges to turn your vision into amazing artwork. We have highlighted some directions and tips below for creating your first glass painting.

 

Preparing the Glass

Wondering how will acrylic paint stick to glass? Well, first the glass surface needs to be prepared. Glass is very smooth, so the paint will; need a suitable surface to adhere to. When preparing the glass, start by washing it completely in soapy water. Wait for the glass to air dry. When dry, wear latex gloves to make sure you don’t leave any marks or fingerprints on the glass. Wipe down the entire glass surface with rubbing alcohol or vinegar and let it air dry again.

If you are painting a drinking glass, then tape off the edges that you will drink from. Having paint over areas where you drink can cause the paint to chip away faster. If there are any other places that you don’t want to be painted, then tape over these too. Then coat a base coat over the entire glass with a wide brush. You can add gesso as the base coat for glass surfaces that you want to achieve an opaque effect over. If you will not be painting the glass surface completely, and just want to add some design flourishes, then skip this step of adding a base coat.

Make sure that the base coat is completely dry before adding any more layers of paint. This should be left for at least an hour. You don’t want the second layer of paint to blend into the first coat.

 

Painting Glass With Acrylic Paint

The glass is now properly cleaned, primed, and ready for painting. Now you can start to apply your design. It’s a good idea to draw out the design on paper first. This can be traced onto the glass for greater accuracy. Make sure that the paints you will be using are prepared, mixed, and ready to go. You can trace the outline of the design with a marker over the glass surface. This can be done by sticking the stencil on the inside of the glass, as long as the glass is still clear and doesn’t have a base coat. This technique is also used for applying liners. Don’t worry about getting marker lines perfect. Any unwanted lines can be easily washed off after the paint has dried.

Now you are ready to start painting. You can use whichever brushes you prefer for creating the desired effect. Syringes can be used too for adding small dots of detail.

  • Start with a single color. Use light strokes and paint towards you from the furthest away point of the glass
  • Make sure that your brush is thoroughly cleaned before switching colors. Paint thinner may be needed when using enamel paints
  • Then switch to the next color and continue painting. Try not to blend any colors together by mistake
  • If you are concerned about mixing wet colors together, you should wait for each color to dry before adding the next. This will allow you to get nice clean color blocks. The paints should take about an hour to dry

Any mistakes can be erased using cotton buds soaked in acetone or rubbing alcohol. This can easily rub out any mistakes and works well for getting rid of small detailed errors. You can also paint a second coat for brighter, more intense colors. Sometimes acrylic paints will appear lighter when they have dried, so a second coat helps to make the true color pop. Just make sure to use exactly the same color.

 

Tips for the Design

By creatively using the paint brushes and painting tools, various effects can be achieved. Here are some useful design tips and tricks.

  • You can tape a pattern on the inside of the glass to trace over the outside easily
  • For painting straight lines, you can use tape as a marker. Paint over the edge with a flat brush and remove the tape while the paint is still wet to avoid peeling off and chipping any paint. You can use a craft knife to carefully clean up any bad edges
  • For dots and spots, a dauber or large sponge can be used. Any small handle or point can be used for making small dots. You can simply add paint to the tip and press it on the glass, then remove the point straight – without an angle. This will create a perfect dot

Drying the Paint

Different paints have different drying times. Usually, acrylic paint on glass will take about an hour to dry. With some enamel paints, the drying process could take a full week before they are cured. To dry out the paint entirely, the glass is best left out in a warm and sunny area. Will acrylic paint stick to glass when dry? Yes, but this can be enhanced through baking or sealing. Applying a sealant adds extra protection, and baking provides numerous benefits to the glass artwork. We will explore these further later on.

 

 

Maintaining the Acrylic Paint on Glass

Even though enamel-based acrylic paints are incredibly durable, glass painted with them requires special care for a long lifespan. Ideally, you want to create a glass that is dishwasher-safe – something that depends on the exact paints used.

Never soak or scrub painted glasses. And definitely don’t use abrasive materials on them. Make sure to read the manufacturer-specific cleaning instructions first. You should often wipe and dust the glass to avoid deep cleaning it. Simply wiping down the glass with a damp cloth is a good way to clean it. If the glass is washed and used very often or exposed to sunlight a lot, the paint will not last as long.

 

 

How to Seal Acrylic Paint on Glass

There are two ways of sealing acrylic paint on glass. You could either bake the item or cover it with a sealant. For extra precautions, both methods can be done. Sealants are good for purely decorative items but are not ideal for food or drinking glassware. Oven baking is usually the preferred method as it provides the best long-term durability and protection.

 

How to Seal Acrylic Paint on Glass: Using a Sealant

A sealant can be brushed or sprayed over the painted glass surface. Spraying sealers are generally preferred because there is less contact with the fresh glass, and you can achieve a nice even finish. Just make sure to understand the specific sealant that you are using before applying it. When spraying, always try to do so in a well-ventilated area, as there can be powerful fumes arising. Gently sprayed the sealant over the whole area, and don’t focus too hard on any specific point. The aim is to get a nice even finish.

  • Before adding a second and third coat, make sure that the underlying one is dried first. This will vary between products, but it should generally be about 15 minutes. You will need at least two or three layers of sealant
  • If brushing the sealant on, use a paintbrush and coat the entire surface as if it was painted. Be careful, as you want to achieve a smooth and even finish without any brush marks. You should also paint at least two or three coats here. Just be aware that brushed on sealant takes longer to dry

Whichever method you take with applying the sealant, make sure to leave the piece for at least 24 hours to dry completely.

 

 

Painting on Glass with Acrylics: The Best Sealer

If you choose to add an additional layer of protection to the acrylic paint on glass, then using a sealer works well.

How to Bake Acrylic Paint on Glass

Some acrylic paints come with instructions on how to bake them and what temperature is best. Always check this first. When baking glass, always place the item in a cold oven. The glass needs to heat up very gradually and will get damaged if placed directly into a hot oven. You should set the oven to around 300 to 350 degrees Fahrenheit and bake the glass for about half an hour once it reaches the correct temperature. Then turn the oven off, and leave the glass inside it to cool down. Only open the door and take the glass out once the oven is completely cooled down.

When the glass does come out of the oven, you still need to leave it to cure fully. This process should take about 72 hours before you can use the glass.

 

Tips and Tricks for Oven Curing

  • Make sure that there are no cracks or chips in the glass. If there are, there is a good chance that the glass will shatter in the oven
  • Spraying the glass with a coating of all-purpose primer or sealer first will help the acrylic paint on the glass to stick
  • When painting on clean glass, always try to wear gloves. Otherwise, you will leave behind fingerprints and marks on the glass. The natural oil left behind from your skin can affect how the paint sticks
  • Even though glass items are generally dishwasher safe when baked in the oven, handwashing them is still best. Always be careful when washing them, and use a very soft cloth
  • When using a chemical sealer, only do this on decorative items. Any glassware for food and drink should be cured in the oven
  • When painting the glass, do not paint in areas where there will be direct contact with food or drink consumption. For example, tape over the rim of a drinking glass so that you don’t put your lips over the paint. This will help to protect the paint, and it will stip you from ingesting any paint that might flake off. The other option is to paint the reverse side of the glass piece
  • Painting on glass shouldn’t be done with recycled glass. Recycled glass contains different glass materials and soda ash which lowers its COE. Rather go for new, fresh glass which is much stronger
