How to Remove Contact Cement From Fiberglass
- 1). Hold a heat gun about 4 inches from the fiberglass surface above the contact cement you need to remove. Turn on the gun and pass it back and forth over the cement to soften the material.
- 2). Scrape away the softened contact cement with a flat putty knife scraper, taking care not to gouge the fiberglass beneath. Remove as much of the cement as possible using the heat-and-scrape method, then turn off the heat gun and allow the surface to cool.
- 3). Place contact cement solvent into an oil can and squirt the remaining contact cement with the solvent. Leave the mineral spirits in place for 5 minutes in order to soften the cement.
- 4). Remove the softened cement using a rag to wipe it away. Change rags whenever the cloth surface fills with the cement to avoid smearing softened adhesive over the fiberglass. Use multiple applications of the solvent if necessary to remove the cement.
- 5). Wash the fiberglass with clean water to remove any residue remaining from the cement or solvent.
