Removing roofing cement from a stone outdoor table can be tricky, but with the right approach, you can restore its natural beauty without causing damage. Here’s a step-by-step guide:

1. Scrape Off Excess Cement: Use a plastic scraper or putty knife to gently remove as much dried cement as possible. Avoid metal tools to prevent scratching the stone.

2. Apply a Solvent: Choose a solvent like mineral spirits or acetone. Test it on a small, hidden area first to ensure it doesn’t discolor the stone. Apply the solvent to the cement and let it sit for 10-15 minutes to soften.

3. Scrub Gently: Use a stiff-bristle brush or a nylon scrub pad to loosen the cement. Work in small sections to avoid spreading the residue.

4. Rinse Thoroughly: Wash the area with warm, soapy water to remove any remaining solvent or cement particles. A pressure washer on a low setting can help for stubborn spots.

5. Repeat if Necessary: For thick layers, repeat the process until the cement is completely gone.

6. Seal the Stone (Optional): After cleaning, consider applying a stone sealer to protect the surface from future stains.

By following these steps, you can effectively remove roofing cement and keep your stone outdoor table looking pristine. Always wear gloves and work in a well-ventilated area when using solvents.
