What are the best methods for preventing algae on concrete outdoor chairs near fountains?

Algae growth on concrete outdoor chairs near fountains is a common issue due to constant moisture and shade. To prevent this, follow these effective methods:

1. Regular Cleaning: Scrub chairs weekly with a mixture of water and mild detergent to remove dirt and early algae spores.

2. Use Algae-Resistant Sealants: Apply a waterproof, algae-inhibiting sealant to the concrete surface every 6-12 months.

3. Improve Sunlight Exposure: Rearrange furniture periodically to allow sunlight to dry and disinfect the surfaces.

4. Vinegar or Bleach Solution: Spray a diluted vinegar or bleach solution (1:10 ratio) monthly to kill algae without damaging the concrete.

5. Proper Drainage: Ensure the area around the fountain has good drainage to reduce standing water near the chairs.

By implementing these steps, you can keep your concrete chairs algae-free and extend their lifespan.
