Q: Can you epoxy over asbestos tile?

• <div><p>Epoxying over asbestos tiles is generally considered a safe option when done correctly.

The key is ensuring that the asbestos tiles are in good condition, firmly adhered to the substrate, and not damaged or deteriorating. This method is only appropriate for tiles that are undamaged and securely in place. If the asbestos tiles are already loose, damaged, or deteriorating, encapsulating them with epoxy may not be a sufficient solution, as it might not address the potential for ongoing asbestos exposure.</p></div>
