Painting on glass can be rewarding but tricky—especially when using acrylics. While acrylic paint doesn’t naturally adhere to slick surfaces like glass, with the right materials and preparation, it’s possible to achieve vibrant, long-lasting results. In this article, we break down which acrylic paints are best suited for glass, how to prepare the surface, and how to seal your work to make it durable and display-ready.
Not all acrylic paints are created equal. Standard student-grade or low-viscosity acrylics may slide or chip off glass if applied without a proper base because they lack the binder strength needed for non-porous surfaces. This can result in uneven coverage and a fragile finish that won’t last through handling or cleaning.
For the best outcome, use high-quality artist acrylics with strong pigmentation and flexible binders. These premium formulas are better equipped to grip smooth surfaces and withstand layering, sealing, or even oven-curing processes. Investing in the right paint gives you more vibrant color and long-term durability.
Before painting, clean the glass with warm soapy water followed by isopropyl alcohol to eliminate grease, oils, and fingerprints. This step is critical—any residue left behind can act as a barrier between the glass and your paint. Once cleaned, avoid touching the surface with your fingers to prevent reintroducing oils.
For added durability, lightly sand the glass with fine-grit sandpaper or apply a glass-specific primer or etching medium. These techniques give the glass a slightly roughened surface, helping the paint adhere more effectively and minimizing the chance of peeling later.
Thin layers: Apply thin coats and allow each layer to dry completely.
Soft brushes: Use high-quality soft brushes to avoid streaks and brush marks.
Detailing: Use fine liner brushes for outlining or decorative touches.

To make your painted glass permanent and moisture-resistant, always seal your work after it’s fully dry. A clear acrylic sealer or varnish designed for glass will protect the surface from scratches, smudges, and wear. Choose your finish—gloss, satin, or matte—based on the final look you want to achieve.
Some acrylic paints are also labeled “bakeable,” meaning they can be cured in the oven for extra hardness. Be sure to follow the manufacturer’s curing instructions closely, including bake time and temperature, to avoid cracking or discoloration.
Practice on spare glass before moving on to your final piece. This lets you get a feel for how the paint reacts and how many layers you'll need for full coverage.
After sealing, store your artwork in a dust-free, dry environment while it cures to ensure a clean, lasting finish.
Avoid washing or scrubbing the painted area for at least a week after sealing to allow the protective coating to fully set.
With the right supplies and process, acrylic painting on glass opens up an exciting new surface for creative expression. Just make sure you prep well, use the right paint, and seal with care—and your designs will stay vivid and intact for years to come.
