Basic to boujee: Acrylic paint pens on glass cups

Welcome to my latest obsession – using acrylic paint pens on glass cups – or rather those cute glass cans with lids!

Acrylic paint pens on glass cups

There are all kinds of ways to decorate glass cups or glass cans. UVDTF (UF direct to film) is a very popular method. However, I LOVE to opt for hand painting everything. This is a current set of glasses I painted and it was so relaxing. And don’t worry, you can seal them so you can use them on the regular!

I think these make perfect gifts or this project is fun for a craft night, or just to relax.

Materials Needed:

Clear glass cans (cleaned and dried thoroughly)
Acrylic paint markers (variety of colors, including lighter and darker shades)
Clear varnish that is dishwasher safe (glossy or brush-on)
Rubbing alcohol and a lint-free cloth (for cleaning)
Optional: Template that you can tape inside the glass so you can trace.

Here is a video I made of the process.

How to use these paint pens

This set requires priming the tip. Shake each pen really well before using. You can tell when it is ready when the color look solid and mixed well in the tube. Remove the cap and press the white tip on a piece fo scratch paper. Hold it down until you see the paint flow to the tip.

Anytime you are using the pen and it feels dry, simply press the tip down hard on the surface until it flows again.

Paint pens are different from markers because rather than filled with ink, they are filled with acrylic paint. When you paint on glass, it literally is as though you used craft paint. It will dry flat and with a matee finish and can easily be scraped off.

Sealing is essential.

Step-by-step directions

Prepare the Surface:

Clean the glass can thoroughly with rubbing alcohol to remove any dirt, grease, or fingerprints. Let it dry completely.

Base coat the designs and start outline:

Start by sketching a design on paper, if you want, you can slide/tape it inside the glass so you can trace it.
Use lighter colors to paint the base of your design. These lighter shades act as a foundation and help the design pop against the clear glass. For example, if painting a floral motif, begin with the petals in white or pastel tones.
Let each layer dry for about 10-15 minutes before adding more layers, ensuring an opaque and even base.

Outline with darker colors, add accents:

Once the basecoat is dry, use darker colors to outline the shapes or add details. For example, use black or dark green to outline flower petals or leaves. This step adds definition and depth to your design.
Work slowly to ensure clean, precise lines. Acrylic paint markers are great for this as they offer excellent control.
Incorporate contrasting colors to create accents and bring the design to life. For example:
- Add yellow dots in the center of flowers for a pop of brightness.
- Use metallic or glitter paint markers for highlights, such as gold accents on geometric patterns or stars.
Blend or layer colors carefully to add dimension.
Inspect the design for any gaps or uneven areas. Fill in as needed, and add final embellishments, like small dots, swirls, or lines for extra flair.

Seal your work!

Allow the painted design to cure for at least 24 hours to ensure it is completely dry.
Apply a clear varnish to protect the design and make it durable for handling. Use a soft brush to apply a thin, even coat over the design. Avoid over-brushing, as it may smudge the paint.
Let the varnish cure according to the manufacturer’s instructions (usually 24–48 hours).

Tips for acrylic paint pens on glass cups:

Work in thin layers to prevent smudging or uneven coverage.
If you make a mistake, use a damp cloth or cotton swab with rubbing alcohol to erase the paint before it dries.
Avoid painting areas near the rim where the lips will touch for safety.
Hand wash the glass cans gently with warm water and avoid abrasive sponges to preserve the design.
