Have you ever used mod podge on a project and been so frustrated because it bubbled up and just didn’t look good? ME, TOO! It’s frustrating to say the least. But..there’s an answer!
I’m going to show you how to do the mod podge iron method to avoid bubbles and I promise you, it’s going to be a game changer!
A few simple supplies are what is going to change things for you and I promise it’s super easy too!
We’ve all been there…working on a craft, things are going well and then BOOM…the mod podge bubbles creep in. Ugh. Nothing worse! Here’s the solution.
GET THE MINI IRON HERE! IT IS LINKED UNDER CRAFT SUPPLIES!
For this little reversible sign, I simply prepped my surface by painting it white and then let it dry. You can find the printable bundles that I used for this project in my store here!
When you are ready to mod podge…DO THIS!
What this is doing is reactivating that glue underneath that has dried. And the result?! SUPER SMOOTH….NO BUBBLES…NO WRINKLES…PERFECT CRAFT PROJECTS!
Mod Podge doesn't contain solvents that degas and create bubbles in the finish. If you are getting bubbles in the finish, it's either because of air bubbles that got mixed into the product, or air trapped during application.
Getting rid of bubbles in the product
As Allison C notes in a comment, the product gets a lot more shaking before it ever gets to you than what it got being knocked off the table. It's a thick liquid, so it can take a while for bubbles to all work themselves to the surface. If the container sits for a few days, any bubbles should rise to the top.
The same would apply if you ever decide to stir the contents. Stir slowly to not introduce air, then let it sit for a few days.
There's a way to speed up getting rid of any air bubbles. Slowly pour the contents into another container in as fine a stream as you can. If you want to store it in the original container, pour it back the same way. For this to work, you need patience to avoid the temptation to speed things up. Any air bubbles will end up at the top of the product in the container you pour into, where they can easily escape.
Avoiding bubbles in the coating
Even if there are no air bubbles in the product, you can still get bubbles during application. There are two main ways. If what you're coating has a lot of surface texture and detail, you can trap air when you apply the coat. If you use a scrubbing motion with the brush, that can stir in air. If you are applying a thick coating, air from those sources can aggregate as bubbles. The coating dries from the outside in, so the surface can trap them. Even if the bubble pops, the coating may be viscous enough at that point to not flow into the bubble hole, leaving a pock mark.
