Hello! If you’re joining me to get the quick answer to the question “Is Mod Podge waterproof?” then I’d like to let you know right away: NO. Of course there is a more detailed answer, but I figured that some of you will want to know immediately and run, so there it is.
If you’d like to stick around to find out more details – and get some solutions to making Mod Podge waterproof – then I’m here for you. One of the most common questions I get on this blog from readers is, “Is Mod Podge waterproof for coasters?”
Typically someone might be making coasters for a gift and are interested in how to make the coasters waterproof as well as heat resistant. Which would be expected since coasters are exposed to water from glasses as well as extreme heat from hot beverages.
There are many other projects that crafters are interested in making waterproof (besides coasters) such as garden items or anything that might be outside on a porch or patio. Kids’ tables and dressers are another common theme based on the fact that kids can be rough on stuff and also so many spills.
So now let’s answer the question you’re all wondering in more detail: Is Mod Podge waterproof?
Is Mod Podge Waterproof?
As I said before, no, Mod Podge is not waterproof. The longer answer has to do with the makeup of the product. Mod Podge is a craft supply made up of several ingredients, including vinyl acetate. The combination produces a product that is somewhat water resistant, but not waterproof.
If a few drops of water end up on your Mod Podge project you can wipe them away with ease. You aren’t going to ruin your craft with just a little bit of water.
The issue is when something that is Mod Podged is exposed to a lot of water. The product is not “built” for submerging or exposure to water over a long period of time (and consistently). For example, you wouldn’t want to put something only sealed with Mod Podge in your shower. This is true for Mod Podge as well as all other decoupage mediums.
Note: if water is on your Mod Podge project for an extended period of time, you might notice some clouding. Typically when you remove the water the Mod Podge will slowly dry to clear again. However, you might see some permanent cloudiness and/or rings.
What about Outdoor Mod Podge?
You can learn more about Mod Podge Outdoor here. As I mention in that article, Mod Podge Outdoor is not waterproof. It is HIGHLY water resistant (more so than regular Podge). This means that if you want a decoupage item to sit on a covered porch where it is not exposed to weather 24 hours a day, you are fine using this formula by itself.
HOWEVER – if you live in Seattle and your project is constantly rained on, or you live in Arizona and the sun is beating down on your craft all the time, I suggest another sealer that is waterpoof and/or UV resistant on top.
What about Dishwasher Safe Mod Podge?
You can learn more about Dishwasher Safe Mod Podge here. It is very highly water resistant (top rack, dishwasher safe) but even that formula isn’t completely waterproof.
This version of Mod Podge is highly durable, and perfect for using with mugs or placemats or something that will be exposed to water but not for a long period of time. People make glitter mugs all the time with this medium and they last for a long time after repeated dishwasher runs.
Is Mod Podge permanent (since it isn’t waterproof)?
Technically, no. BUT if you Mod Podge a piece of paper to wood, it’s not going to come off without some serious work. You’d have to peel the paper off, or sand it off, or leave water on it for an extended period of time (which would probably end up ruining the wood too!). Mod Podge comes off of glass more easily than other surfaces, and soaking typically works to remove it.
For my purposes, and in my crafts, Mod Podge is pretty permanent. I’ve seen 50 year old projects from the creator of Mod Podge (Jan Wetstone) that are still going strong. So while I can’t *technically* say the product is permanent, you’re going to have a hard time removing it.
Do you need to seal Mod Podge?
No, you do not need to seal Mod Podge. It is a glue, sealer, and finish all in one. The Mod Podge Hard Coat in particular has very tough properties that make it suitable for sealing furniture. However, sometimes you need to break out the big guns and you want to make a project relatively waterproof!
For those times, I recommend a product like Thompson’s WaterSeal painted right over the top, after your decoupage project is completely dry.
This doesn’t mean you’ll be able to submerge your project (I don’t recommend ever submerging a decoupage craft), but it will be pretty close to waterproof in terms of be exposed to rain or other water on a regular basis.
And while we’re on the topic of sealing, let’s get back to coasters.
You can use something like Thompson’s WaterSeal on coasters and it will be fine for most applications. Thompson’s and Minwax Polycrylic are commonly used by Etsy sellers who sell coasters.
The only issue is if your item is going to be exposed to extreme heat (like a trivet would be). Then you’ll likely want to use a resin. Learn about Dimensional Magic vs resin here.
Is Mod Podge waterproof? No. But it’s highly water resistant and if you’re looking for a tough decoupage medium, it’s the one for you! Let me know your thoughts in the comments!
