Sharing is caring!

Learn how to create perfectly painted mason jars by adding paint to the inside of the jar. I’ve tried different methods and this is the best!

I’m super excited to share this mason jar craft with you.

The second I saw this gorgeous metallic green paint from DecoArt, I immediately thought it would be perfect for glass-and I was right!

But I didn’t stop with green. I also painted the prettiest pastel colored mason jars to use in my spring decorating.

Once you see how easy it is, you will want to paint “all the jars”!

If you follow me on Pinterest you may have seen the tinted mason jars I painted with food coloring.

These were extremely popular and while I’m happy with how they turned out, they were time consuming.

They are painted on the outside and required baking in the oven. A couple of years later they have held up great.

These jars have more of a solid color paint finish. They only took about 20 minutes to paint all 4. Seriously, it’s a matter of mixing, pouring and drying.

There is also a printable craft card at the end of this post to make it even easier for you. Let’s get to it!

How to Paint Mason Jars

Step 1. Choose Your Paint Color

Start by choosing your paint color. I knew I wanted to paint mason jars for Spring, specifically for St. Patrick’s Day and Easter.

I found the most beautiful shade of green that is totally made for St. Patrick’s Day crafts. Isn’t it gorgeous?

The metallic finish works great on glass. I’ve used DecoArt metallic paint in several projects shown below:

In addition to metallic green, I also used DecoArt acrylic paint in blush pink and shoreline.

They are both a pretty pastel color perfect for spring and Easter!

Step 2. Clean The Mason Jar

To get the smoothest paint finish possible, it’s important to clean the jars with rubbing alcohol. You can just use a paper towel.

This will get rid of any fingerprints or dust.

Step 3. Mix The Paint With Mod Podge

To ensure that the paint isn’t too thick and to help it adhere to the glass, it’s important to add a bit of mod podge to the paint.

mixing mod podge

I am an impatient crafter, so I never measure. Use a disposable cup and pour paint about 1/4 of the way full.

Then add a spoonful or two of mod podge. Mix it with a craft stick until it is well blended.

It should be the consistency of yogurt or a little thinner.

Step 4. Pour Paint Mixture Into Glass Jar

Slowly pour your mixed paint into the mason jar. It is best to start with a small amount.

You can always add more. It takes very little paint to cover the jars.

Now you want to slowly rotate the jar around so the paint moves across and covers the entire jar.

If you don’t have enough paint, just pour a bit more.

Step 5. Let Dry Upside Down

Once you’ve covered the jar with paint, place it upside down to dry. You will be surprised at how much paint comes out.

It helps to place it on parchment paper to dry. That way it won’t stick. I tried cardboard and it was a pain to get that off!

When I tell you the finish is perfectly smooth, I am not exaggerating.

I kept showing my daughter because I was so excited.

Now I want to paint all the colors of the rainbow.

The metallic in the green paint looks even prettier in person:

The pink and blue are exactly what I was envisioning for spring. I do have an Easter decorating idea for these.

Be sure to stop by next week to see it!

I have painted these jars for years on the outside. I never thought about painting them on the inside, so would I spray a sealer on the inside so I could fill it with water for fresh flowers your jars are beautiful.


Tuesday 7th of February 2023

I'm wondering if the inside needs to be sealed after the paint dries so fake flower stems don't scratch or chip it.


Wednesday 8th of February 2023

You can definitely spray the inside with a sealer, or bake them in the oven to be safe. I haven't done that yet. But I will probably take care of that this weekend. I'll update the post to include that. Thanks so much! :)
