What You'll Learn
Use a heat gun to soften the adhesive
Using a heat gun to soften Liquid Nails adhesive on polystyrene is an effective method, but it must be done with caution to avoid damaging the polystyrene.
Heat guns are handheld devices that emit a stream of hot air, usually between 100°C and 550°C (200-1000°F). Some models can reach temperatures of up to 760°C (1400°F). When using a heat gun to remove adhesive, it is important to keep the temperature below 200°F to avoid damaging the polystyrene. Start with the heat gun's lowest flow speed and temperature settings, and always keep the gun in motion, moving it around in little circles.
Before using the heat gun, make sure you have a plan in case of a fire. Keep the device unplugged when not in use and avoid using extension cords, as they may pose an additional fire risk. If you are heating the adhesive near or underneath a battery, discharge the battery first.
To soften the adhesive, position the tip of the heat gun 2-3 inches above the glued area. The exposure time will depend on the type of adhesive, temperature, and distance between the heat gun and the surface. Keep the heat gun in constant motion, moving it along the area with adhesive.
Once the adhesive has softened, use a plastic scraper or putty knife to gently remove it. Be careful not to scratch the polystyrene surface. If the adhesive is particularly stubborn, you may need to repeat the heating and scraping process several times.

Scrape away the softened adhesive
Scraping away softened adhesive is an effective way to remove Liquid Nails from polystyrene. This method is especially useful when dealing with dried adhesive, which can be challenging to remove due to its resistance to solvents and high-temperature resistance.
To begin the process of softening the adhesive, you can apply heat using a blow dryer or a heat gun set to a temperature above 140 degrees Fahrenheit. It is important to continuously apply heat while gently scraping away the adhesive with a plastic scraper, putty knife, or similar tool. This step requires careful execution to avoid damaging the surface.
For more stubborn adhesive residue, you can utilize baby oil, petroleum jelly, or vegetable oil. Apply a light layer of the chosen substance to the affected area and let it sit for about half an hour to soften the Liquid Nails. After this, gently wipe the area with a clean cloth and wash it with soap and water. This process may need to be repeated several times to ensure the complete removal of the adhesive.
Another option for softening the adhesive is to use mineral spirits, acetone, or a dedicated adhesive remover. These chemicals can be applied to the surface and left to work for a short period before scraping. However, it is crucial to exercise caution and test these substances on a small, inconspicuous area first to ensure they do not damage the polystyrene.
Throughout the scraping process, it is important to work gradually and patiently. Depending on the extent and stubbornness of the adhesive, you may need to repeat the softening and scraping steps multiple times until all the Liquid Nails has been removed. Remember to wear protective gear, such as rubber gloves and safety glasses, when handling chemicals and during the removal process.

Use adhesive remover
Removing liquid nails from polystyrene can be challenging, but it is possible with the right approach and a bit of patience. Here is a step-by-step guide on how to use an adhesive remover to tackle this task:
Prepare the Surface:
Start by gathering your materials: you will need adhesive remover, rubber gloves, safety glasses, a soft cloth or paper towels, and possibly a plastic scraper or putty knife. Always ensure you are working in a well-ventilated area when using chemicals, and it is recommended to wear protective gear, including gloves and safety glasses, to avoid any skin or eye contact with the adhesive remover.
Apply Adhesive Remover:
Follow the instructions on the adhesive remover product you have chosen. Typically, you will apply a small amount of the remover directly to the area covered in liquid nails. Allow the remover to sit for the recommended time, which may vary depending on the product. The remover will start to break down the adhesive, making it easier to remove.
Remove the Adhesive:
Once the remover has had sufficient time to work, use a soft cloth or paper towels to wipe away the dissolved adhesive. If needed, gently use a plastic scraper or putty knife to help lift away any remaining residue. Be cautious not to apply too much pressure to avoid damaging the polystyrene surface.
Clean the Surface:
After removing the bulk of the adhesive, you may want to use a damp cloth with warm soapy water to wipe down the area and remove any remaining residue. Ensure you are gentle and do not apply too much pressure or rub too vigorously, as you do not want to damage the polystyrene.
Additional Tips:
If you are having trouble finding an adhesive remover, some alternatives can help. One option is to use mineral spirits to wipe down the surface and remove any remaining residue. You can also try softening the adhesive by applying heat with an electric heat gun or blow dryer, but be cautious of the heat source and do not let it come into direct contact with the polystyrene, as it may melt or deform.
Remember always to refer to the product labels and safety data sheets for any commercial products you use, and always work in a well-ventilated area when using chemicals. With the right approach and some patience, you can successfully remove liquid nails from polystyrene.
