Leftover Expanded Polystyrene: From Trash to Treasure with These Ingenious Reuse Ideas

Clear Styrofoam Varnish:
In addition to the thick paste, Styrofoam can also be dissolved in acetone and a general-purpose polyurethane thinner. You will obtain a clear varnish, which can be used to protect and finish various surfaces. Next

Here are the steps to create this varnish:

Gather the Styrofoam Scraps: As in the previous step, be sure to collect the scraps you want to reuse.
Shred the Styrofoam: Shred the Styrofoam into small pieces or shreds, in the same way as the previous process.
Safety Precautions: It is important to carry out this process in a well-ventilated area and away from heat sources or open flames. Dissolving in acetone and universal thinner: Place the polystyrene pieces in a sturdy container and pour in acetone and universal polyurethane thinner in a ratio of 2 to 1. Allow the polystyrene to dissolve in the mixture for several minutes, stirring occasionally to speed up the process.
Obtaining the varnish: Once the polystyrene is completely dissolved, you will have a clear varnish. It can be applied to various surfaces to protect them and give them a glossy, durable finish.
By reusing polystyrene foam, we not only reduce the environmental impact associated with its disposal, but also open up a world of creative possibilities for using these new materials in various crafts and projects.
