Hold the heat gun or blow dryer close to the adhesive, maintaining a safe distance to avoid any potential fire hazards. Keep it moving to ensure even heating and prevent overheating any particular area.
Scrape away the softened adhesive:
Once the Liquid Nails have softened sufficiently, use your scraper to gently remove it from the cement wall. Hold the scraper in one hand and continue applying heat with the blow dryer or heat gun in the other hand to keep the adhesive soft. Work in small sections, scraping away the adhesive as you go. Be careful not to apply too much pressure to avoid damaging the underlying cement wall.
Repeat the process as needed:
Depending on the amount of adhesive and the severity of the bond, you may need to repeat the heating and scraping process several times to completely remove all the Liquid Nails from the cement wall. Be patient and persistent, as it may take multiple attempts to fully remove the adhesive.
Clean the surface and inspect your work:
After removing as much of the Liquid Nails as possible, wipe down the cement wall with a damp cloth or mineral spirits to remove any remaining residue. Ensure that all traces of the adhesive are gone and that the wall is smooth and free of any sticky residue. If you notice any areas you missed, repeat the heating and scraping process until you achieve the desired result.
