If you’ve ever dealt with a project that involves attaching something to Styrofoam, there’s a good chance that liquid nails have crossed your mind.
Liquid nails are a trendy brand of glue—and they’re always available at the hardware store.
But can you use it on Styrofoam or foam board? Unfortunately, no: liquid nails shouldn’t be used for this project. Here’s why

Liquid nails are not recommended
Liquid nails are not recommended for use on foam board.
Liquid nails are made to be used with materials that contain a certain amount of natural moisture. The wrong kind of liquid nails can melt your foam board.
Liquid nails contain natural moisture
You’re right to be skeptical of using Liquid Nails on foam board. Liquid Nails are used with materials that contain a certain amount of natural moisture, such as wood and drywall since it is a water-based glue.
It’s not recommended for use on anything more than 20% moisture content, like foam board which has no natural moisture to speak of.
Liquid nails are not proper adhesive
If you’re using liquid nails to attach something heavy, you will want to use glue that can handle the object’s weight.
Contact cement or hot glue are better options for this type of project.
You could also use a heavier foam board that can handle the weight, but keep in mind that your finished project won’t be as lightweight and easy to transport.
Conclusion
A better option would be to use another type of glue or adhesive explicitly made for foam board.
The best part about using this type of glue is that it will not affect the integrity of your Styrofoam, nor does it contain any harmful chemicals.
