Are you struggling to get your paint to stay on glass surfaces? If so, this post takes you through the steps involved in preparing your glass, how to paint it, and the best methods to seal your designs so that they last. 

Preparing Your Glass Painting

• If the glass items are dishwasher safe, you can put them in the machine to be cleaned. If not, hand wash the glasses with warm soapy water.
• Leave it to air dry.
• Next, wear some latex gloves to prevent any oils from your hands from being transferred onto the glass. 
• Apply a small quantity of rubbing alcohol to a paper towel and gently wipe the glass. 
• If you don’t have rubbing alcohol, white vinegar can be used as a substitute. 
• Leave the glass to air dry again before you start painting.

Painting Your Glass Piece

• Make sure that you put some tape around the top edges of the glass if you plan to use them for drinking. This ensures that if there are any toxins in the acrylic paint markers, they don’t affect you or anyone else. 
• Read the label on the packaging of your chosen paint and see whether it requires an overcoat or undercoat. 
• You should also check to make sure whether there are any other instructions to get the best results. 
• Next, it’s time to get your design from paper onto the glass. 
• Use a permanent marker to draw the design directly onto the glass. 
• The outline from your design can be used to guide you when painting.
• You can start filling in the design with your chosen paint colors and paintbrush.
• It’s a good idea to keep some cotton pads and rubbing alcohol or nail polish remover nearby.
• If you make any mistakes, just dip the cotton pads or swabs into the solution and gently erase your mistake. 

Sealing Paint On a Glass Surface

• Read the label for your spray varnish to see if there are any specific instructions. 
• Next, make sure that you’re either outdoors or in a well-ventilated place. This is because spray on sealant can produce a strong smell. 
• Begin spraying the sealant onto your glass design by holding the spray around 12 inches away. 
• Use a sweeping motion going back and forth over the design. Make sure not to hold the spray in one area for a period of time to ensure that you get an even seal.
• After you’ve applied your first layer, leave it to dry for around 15 minutes. You can then repeat the steps 3-5 more times before leaving the glass to air dry for 24 hours.

FAQs

Can you seal paint on glass by baking it?

Yes! Start by checking the label of your acrylic paint to see the recommended baking times for the best results. 

Once you’ve painted your glass, place it on parchment paper and put it into the oven and turn the heat on between 300 and 350 degrees. Let the glass bake in the oven for 30 minutes before turning the oven off and leaving the glass to be completely cooled inside the cold oven.

Be sure to avoid removing the glass from the oven right away. This sudden change in temperature can cause the glass to break. 

Can you use Posca paint pens on glass?

Yes, Posca pens permanent ink can be used for glass art projects.

Can you use Sharpie paint pens on glass items?

Yes, the ink from Sharpie markers can be used on wine glasses due to how they’re permanent markers. However, acrylic paint pens are more effective and last longer.

Can you use oil-based paint pens for a drinking glass?

Yes, an oil-based paint pen can be used for glass artwork. However, it’s unlikely to last as long as the ink from acrylic pens.
