What is the best way to prevent algae growth on stone outdoor tables?

Algae growth on stone outdoor tables can be a persistent problem, especially in humid or shaded areas. To prevent algae from taking over your outdoor furniture, follow these effective tips:

1. Regular Cleaning: Clean your stone table regularly with a mixture of water and mild detergent. Scrub the surface gently to remove dirt and organic matter that algae feed on.

2. Use Vinegar or Bleach Solution: For tougher algae, mix equal parts water and white vinegar or a diluted bleach solution (1 part bleach to 10 parts water). Apply the solution, let it sit for 10-15 minutes, then scrub and rinse thoroughly.

3. Improve Airflow and Sunlight: Algae thrive in damp, shaded areas. Trim overhanging branches or move the table to a sunnier spot to reduce moisture buildup.

4. Apply a Sealant: Use a stone sealant to create a protective barrier that prevents algae from adhering to the surface. Reapply the sealant annually for best results.

5. Remove Standing Water: Wipe off any standing water after rain or spills to keep the surface dry and less hospitable to algae.

By following these steps, you can keep your stone outdoor tables algae-free and maintain their natural beauty for years to come.
