Things You'll Need
Heat gun or hairdryer
Hot glue is a highly effective adhesive that creates a lasting bond within one minute of drying to a surface. It is administered with a hot glue gun and is rather simple to manage when freshly applied. Hot glue can, however, be somewhat difficult to remove once it has hardened. Mishaps can occur when working on a project, and hot glue may need to be removed from a cement block wall. Fortunately, this can be easily accomplished with the proper materials.
Adjust a heat gun or hairdryer to a medium setting and reheat the spot of dried glue. Hot glue is a thermoplastic resin rather than a solvent-based adhesive, and softens upon exposure to heat.
Use a scraper blade such as a putty knife or utility knife to test the consistency of the hot glue every few seconds. The heat needs to be applied constantly for the most effective results.
Loosen the glue by scraping it from the foundation. Continue to heat it until it is completely lifted from the surface of the cement.
