Tips

  • Use parchment paper to prevent the cement from sticking to the mold.
  • A less watery cement consistency will create a stronger and more stable repair.
  • Use duct tape underneath the repair to ensure stability while the cement sets.
  • Quick-setting cement allows for a faster repair time.

Common Mistakes to Avoid

1. Using too much water when mixing the cement

Reason: Excess water weakens the cement, resulting in a brittle and less durable repair.
Solution: Follow the manufacturer's instructions precisely for water-to-cement ratio.

2. Applying insufficient Flex Seal or not allowing it to cure properly

Reason: Inadequate sealant leaves the repair vulnerable to water damage, and premature use leads to cracking or peeling.
Solution: Apply several thin coats of Flex Seal, allowing each to dry completely before applying the next.

3. Ignoring surface preparation before applying repair materials

Reason: Dirt, debris, or loose material on the bird bath surface will prevent proper adhesion of the cement and sealant, causing the repair to fail.
Solution: Thoroughly clean and dry the bird bath surface before beginning the repair process.

FAQs

How long does the quick-setting cement take to dry?
Most quick-setting cements will set within 15-30 minutes, but it's crucial to let it cure completely for at least 24 hours before refilling the bird bath with water. This ensures a strong and lasting repair.
Can I use any type of quick-setting cement?
While many work, look for a cement specifically designed for outdoor use and that is waterproof. Avoid using anything that expands significantly as it dries, as this could crack the repair further.
What if the crack is very large or the damage is extensive?
For significant damage, you may need to use a stronger epoxy resin along with the cement and Flex Seal. If the damage is too extensive, professional repair might be necessary. If the bird bath is broken in multiple large pieces, it may not be repairable.
