Glass tiles are available in a wide array of colors, but you can also paint them to add embellishments or to alter the background color. Paint designed specifically to adhere to the slick surface of glass tiles is available at most craft stores.
Things You'll Need
- Glass cleaner
- Rubbing alcohol
- Soft cloth
- Glass tiles
- Painter’s tape
- Glass paint
- Paint sponge/small artist’s paint brush
- Cookie sheet
- Tin foil
Clean the side of the glass tiles that you plan to paint with glass cleaner. Dry the tiles and clean the same side with rubbing alcohol. Rubbing alcohol removes oil and fingerprints that may interfere with the paint. Don't touch the cleaned side of the tiles again with your hands.
Tape a stencil or a template to the clean side of the glass tiles with painter’s tape. Omit this step if you do not need a decorative painting guide, or if you are painting clear tiles a solid color.
Fill in the cutout of the stencil or around the outside of the template with glass paint. Apply the paint with a paint sponge if the surface of the tile is large enough. Paint sponges do not leave brush strokes. Apply the glass paint with a small artist’s brush if you are covering a small area. Remove the stencil/template after painting.
Place the painted tiles face up onto a cookie sheet covered with tin foil. Handle the tiles carefully by the edges.
Follow the glass paint manufacturer’s baking instructions. Baking the paint onto the tiles creates a more permanent adhesion.
Allow the tiles to cool before removing them from the cookie sheet.
