How do you remove mastic sealant

Mastic sealant is a gooey, sticky substance that’s used to bond tiles and stone to surfaces. It’s usually a mixture of cement, lime, and water—and it can be pretty hard to remove if you don’t know what you’re doing.

To remove mastic sealant, follow these steps:

  1. Use a sharp knife or scraper to remove as much of the mastic sealant as possible. Don’t worry if there are still some chunks left behind—you’ll get those later.
  2. Use a putty knife or scraping tool to scrape off any remaining pieces of mastic sealant that didn’t come off with the knife or scraper in step 1. Be careful not to scratch your floor!
  3. Now that all of the mastic has been removed from your floor, it’s time to clean up! You can use warm water and soap or vinegar and water for this step—but make sure no cleaning solution remains on your floor when you’re done!
