Yes, Mod Podge is somewhat heat-resistant. It can take slightly high temperatures, like say, on a coffee mug. Mod Podge won’t last long on an object which experiences high heat regularly. Also, Mod Podge can’t take oven heating at all.
Mod Podge is applied onto surfaces to protect them from UV rays. Mod Podge can be applied to the outer surfaces of some dishes.
Ideally, you just need to apply up to 3/4ths of the outer surface. Leave the 1/4th part of the outer surface that’s near the top. Mod Podge dries off quickly.
That being said, let’s discuss what kind of heat a Mod Podge layer can tolerate. We shall also discuss what other substances can be used to make a surface heat-resistant.
Is Dishwasher safe Mod Podge heat resistant?
Yes, Dishwasher safe Mod Podge can take heat to a certain extent. For example, a dishwasher-safe Mod Podge layer can be heat cured.
You can put the Mod Podged object in an oven and bake it at 175F till the layer is cured well. This way the layer lasts longer.
I’ve cured objects by following the procedure and the Mod Podge layer took it well. You might wanna test it on a different object before applying it to the main one.
Make sure you observed the 28-day curing period before using the mug/object.
Can I put Mod Podge in the oven?
Yes, you can cure those Mod Podge layered objects by putting them in the oven. One needs to put such objects for an hour at 175F temperature.
This is usually done with objects that are covered in dishwasher-safe Mod Podge.
If you’re like me and despise the 28-day waiting period of curing, you may wanna bake the object. The object cures well if it’s baked at the right temperature.
Let the object cool with the oven after you’re done baking it. The object is ready to use after this treatment.
Note: Mod Podge drying white? Here’s Why!
Is Mod Podge microwave safe?
No, Mod Podge isn’t microwaving safe. When you bake recipes, the temperature is quite high and Mod Podge won’t tolerate it.
One can put a Mod Podged object in the oven for curing purposes but the temperature is quite low, i.e., 175F.
You shouldn’t apply Mod Podge on cups/dishes that you wish to use in the oven. The Mod Podge layer can’t take it.
Can you bake dishwasher-safe Mod Podge?
No, the dishes lined by dishwasher-safe Mod Podge won’t handle oven temperature. I wouldn’t use Mod Podge on the dishes that are reserved for the oven.
Mod Podge could withstand a coffee’s temperature. I wouldn’t put Mod Podge directly on the stove or in the oven. Rule of the thumb, don’t expose Mod Podge to direct heat.
Can you iron over Mod Podge?
Yes, you can iron over a layer of Mod Podge provided there’s parchment paper on the surface. Parchment paper protects the Mod Podge layer from excess heat.
Ironing helps get rid of any air bubbles in the Mod Podge layer. Basically, it’s a way to get rid of moisture/air spaces in the Mod Podge layer.
You’d want to iron over the parchment paper using only the heat option. Don’t use any steam while ironing the Mod Podge layer.
Take your own time while ironing and don’t miss any corners. Be patient and slowly move the iron across the entire surface.
Will Mod podge melt in the sun?
No, Mod Podge won’t melt in the sun. But, it won’t stand direct sunlight for long periods either. The project fades if kept in direct sunlight for long hours. It doesn’t tolerate UV for long(fades if kept outdoors for years).
Even outdoor Mod Podge isn’t suitable for objects which will be kept outdoors for many days. You might wanna use a UV sealer.
Mod Podge layer turns yellow over time if it’s kept in sun for long. I’ve seen that it only happens if the object stays outdoors for years.
You can prevent the yellowing of the Mod Podge by keeping the objects away from direct sunlight/direct heat.
Can I use Mod Podge on an ashtray?
No, unfortunately, you shouldn’t use Mod Podge to cover an ashtray. Mod Podge is not fireproof and will get burned.
Mod Podge liquid itself is non-flammable. But, heat can melt a dry layer of Mod Podge. There’s no fireproof Mod Podge.
Mod Podge was invented to be used in kids’ crafts. So, don’t expect much out of this product.
You can use any Acrylic sealer/Acrylic varnish to cover a project and protect it from direct heat. Diamond Elite from the hardware store works wonders.
Heat will soften the Mod Podge layer. Would you want such a thing to coat your ashtray?
Is outdoor Mod Podge heat resistant?
No, Outdoor Mod Podge isn’t heat resistant. The layer of Mod Podge gets discolored if it stays in sun for a long time.
Outdoor Mod Podge is usually applied to objects that are put outside. But, I’ve observed that the Mod Podge layer turns yellow if it’s exposed to sunlight for many years.
So, don’t think that because of its tough-sounding name it withstands all the weather conditions. It won’t.
Is Mod Podge Gloss heat resistant?
No, Mod Podge Gloss isn’t heat resistant. This variant of Mod Podge might resist heat to an extent but not high temperatures.
If Mod Podge gloss comes in direct contact with high temperatures, it will melt for sure. I’d not advise trying this out.
In my opinion, no variant of Mod Podge is heat-proof. Mod Podge is heat-resistant only to a certain extent.
As Mod Podge Gloss isn’t heat-resistant, many craftspersons use Engine Enamel to make the particular object heat-resistant.
Is Mod Podge UV resistant?
Yes, outdoor Mod Podge is UV resistant to an extent. Even outdoor Mod Podge turns yellow if kept outdoors for years.
It could withstand UV for a certain time but not for long hours. Don’t put the objects/furniture on for years if you don’t wanna see them turn yellow.
I’ve seen that the projects fade over time if kept outdoors for long.
Happy crafting 🙂
