  • Flat headed paintbrush

  • Acrylic varnish

While acrylic paint is very sturdy, after it dries on a glass surface it can chip, peel and flake off quite easily. Acrylic varnish is most often used to seal paintings and protect the surface from damage and fading, but it also works very well when used to prevent acrylic paint from flaking off a glass surface. The varnish is available in art stores and online is simple and effective to use.


Step 1

Dip a flat headed paintbrush into some acrylic varnish. You can choose to use a glossy varnish, which will dry shiny, or matte varnish which will dry without shine.
