Solution: Address even the smallest leaks promptly to prevent further damage and costly repairs down the line.

2. Using the Wrong Sealant or Adhesive

Reason: Incorrect sealant can fail to properly bond with the fountain's material, leading to continued leaks or even damage to the fountain itself.
Solution: Always use a sealant or adhesive specifically designed for use with the material of your garden fountain (e.g., concrete, resin, etc.).

FAQs

My fountain is leaking, but I can't see where the water is coming from. What should I do?
Try filling the fountain and carefully observing it. Look for damp spots, dripping water, or even the sound of escaping water. Use a dye tablet (available at most pool supply stores) added to the water to help you pinpoint the source of the leak more easily.
What kind of sealant should I use to repair cracks in my fountain?
The best sealant depends on the material of your fountain. For concrete, use a high-quality concrete sealant. For ceramic or stone, a waterproof epoxy or silicone sealant designed for outdoor use is usually suitable. Always test a small, inconspicuous area first to ensure compatibility and color match.
