It can take up to 24 hours for the puffy paint to dry. It depends on two factors: the air temperature and the humidity in the room. So, if it is hot in your house, or very dry outside, it will take less time to dry than if it were cooler and more humid in your home.

Keep in mind that paint takes longer to dry with multiple coats (typically 2-3 coats) than with just one coat. If made outside, the puffy paint would dry even faster because of the heat and humidity in the air outdoors.

Please note that you should not try to speed up this process by using a fan or heating the room. The paint will dry on its own naturally at its own pace after 24 hours.

There are several other things that directly affect the time that paint can dry. Puffy paint is usually made with acrylic latex. Acrylics are very lightweight unlike oil-based paint, water paints, and other types of paints that are heavier due to the oils that they contain. ‘Acrylics dry faster than oil-based paints because acrylic dries by evaporation (like an alcohol rub on gel packs), while oil-based paints dry by absorption, which is a slower process.

• Humidity: because acrylic paint dries from evaporation, it will become slicker if there is less moisture in the air. The humidity level in your area will directly affect the drying time of puffy paint.
• Temperature: lower temperatures usually mean a longer drying time for paint because it will take a longer amount of time to evaporate the moisture from the air.
• Ventilation: if you can get more airflow around your paint, it will allow the dryer air to reach it more quickly.
• Paint thickness: the thicker you layer your paint, the longer it will take for that individual layer to dry completely.
• Age of paint: if you have a new bottle of acrylic puffy paint, it may take up to a day for it to first dry and become tack-free.
• Thickness of paint: the thicker you apply your paint, the longer it will take for it to dry completely.

In conclusion, the thickness of your paint, how much you have applied, and how old it is will determine the time frame in which your acrylic puffy paint will dry. If you want to speed up the process, try using a paint that does not require drying like Plaid FolkArt Puff Paint.
