Maintenance and Care for Porphyry

Porphyry is low-maintenance due to its durability, but proper care is still needed to ensure it remains in excellent condition. Follow these essential tips to keep your porphyry surfaces looking great for years.

• Seal Porphyry When Necessary: While porphyry is naturally resistant to moisture, applying a sealant periodically (every 3-5 years) will help preserve its appearance and protect it from staining or water damage.
  
• Clean Regularly with Mild Detergents: Sweep or vacuum regularly to remove dirt and debris. Wash the surface with a mild detergent and water to avoid abrasive damage or the buildup of grime.
  
• Avoid Harsh Chemicals: Refrain from using harsh or acidic cleaners that can erode the stone’s surface. Stick to pH-neutral cleaners that are safe for natural stone and prevent damage to the finish.
  
• Blot Spills Quickly: Immediately blot spills, especially from acidic substances like wine or citrus, to prevent staining. Use a soft cloth to avoid spreading the liquid and causing further damage to the surface.
  
• Reapply Sealer Every 5–7 Years: If you’ve used a sealer, reapply it as part of your regular maintenance schedule to ensure continued protection against moisture and dirt. Follow the manufacturer’s recommendations for the best results.
  
• Inspect for Damage: Regularly inspect your porphyry surfaces for signs of damage, such as cracks or chips. Early detection will allow you to address these issues before they become more serious.
