To remove backsplash adhesive from drywall, you can follow these general steps:
Gather the necessary tools: You will need a putty knife or scraper, a heat gun or hairdryer, adhesive remover or solvent (such as citrus-based cleaner or rubbing alcohol), a sponge or cloth, and warm water.
Heat the adhesive: Use a heat gun or hairdryer to warm the adhesive. Hold the heat source a few inches away from the adhesive and move it back and forth to heat the area evenly. Heating the adhesive helps to soften it and make it easier to remove.
Scrape off the adhesive: Once the adhesive is heated, use a putty knife or scraper to gently scrape off the softened adhesive. Be careful not to damage the drywall while scraping. Start from one edge and work your way across, applying gentle pressure to lift and remove the adhesive.
Apply adhesive remover or solvent: If there is any adhesive residue left on the drywall, apply an adhesive remover or solvent to break down the remaining adhesive. Follow the instructions on the product for application. Citrus-based cleaners or rubbing alcohol can also be effective in removing adhesive residue.
Let the remover or solvent sit: Allow the adhesive remover or solvent to sit on the residue for the recommended amount of time. This will help loosen the adhesive further.
Wipe off the adhesive: Use a sponge or cloth dampened with warm water to wipe off the adhesive residue. Gently scrub the area in a circular motion to remove the remaining adhesive. Rinse the sponge or cloth frequently and continue wiping until the surface is clean.
Clean and dry the area: After removing the adhesive, clean the area with a mild soap and water solution to remove any remaining residue from the adhesive remover or solvent. Rinse the area thoroughly and allow it to dry completely before proceeding with any further steps, such as applying a new backsplash or repairing the drywall if necessary.
It's important to note that the specific method and products used for removing adhesive can vary depending on the type of adhesive and the drywall surface. Always follow the instructions provided by the adhesive remover or solvent manufacturer and take appropriate safety precautions, such as wearing gloves and ensuring proper ventilation in the area where you are working. If you're uncertain or dealing with a particularly stubborn adhesive, it may be helpful to consult a professional for guidance.
