Painted on a vase or wine glasses but the paint washed off or got scratched? Not to worry, you can seal acrylic paint on glass to make it permanent and resistant.

Selaing paint on your glassware will also allow you to safely wash it on the top shelf in your dishwasher and use it daily!

The 2 most effective way to seal acrylics on glass is to either use a special sealer like spray sealent, Mod Podge or GAC200 OR to bake it in the oven.

Make sure to check the paint label as certain paints are not bakeable and some modern formulas do not require sealing at all!

How to seal acrylic paint on glass With A Sealer

Acrylic paint acrylics can be sealed with a varnish or glass protector spray to help maintain the acrylic’s appearance for years.

This methods is good for paints that aren’t bakeable and large glassware and items that cannot fit in an average household oven.

The acrylic will not react chemically with these sealants, and they are compatible with most types of acrylic paints.

Seal acrylic paint for glass with a varnish or gloss acrylic sealer to protect the acrylics from yellowing and cracking over time.

You can as well use Golden GAC200, their internal tests proved that using it as a sealer on glass can reduce scratches and protect the painted area.

Be sure to read the instructions on how long you should wait before sealing acrylic paints, as some products require more than one coat of acrylic sealant while others only need one.

I recommend using acrylic sealing mediums Aleene’s or Krylon.

Can You Seal Acrylic Paint on Glass With Mod Podge?

Mod Podge is one of the cheapest and easiest way to seal acrylic paint on glass.

You can use regular Mod Podge but I recommend getting special Dishwasher Safe Mod Podge which will allow you not only to seal the paint but to make sure you can easily clean the wine glasses (or waterver you painting) in future.


How to bake acrylic paint on glass in the oven

Some acrylics are bakeable and I created the Bakeable Acrylic Paint Guide for painting and baking ceramics and glass.

  1. After you finish painting the glass, put your piece into the cold oven.
  2. Set it to 350 degrees F and let it bake for 30 min.
  3. Turn off the oven and let the piece cool for 45 min.

A piece will be fully cured in 24-72 hours.

Baked painted glass will be microwave safe and dishwasher safe. Yet, I do not recommend using it with both on regular basis.

Once you sealed the painted glassware, it is time to move onto the next project! what will it be?
