Waterproofing an outdoor clock is important to protect it from the elements and ensure its durability. As leading experts in exterior clock maintenance, we can restore any clock – commercial, community and domestic to its former glory. However – it can be a costly exercise, which is why we thought it would be useful to share with you a few simple steps on how to waterproof outdoor clocks.

1. Choose a Waterproof Clock: Start by selecting a clock that is designed for outdoor use and is labelled as waterproof or water-resistant. These clocks are typically built with materials that can withstand exposure to moisture.

2. Seal the Clock Mechanism: If your clock has an opening for adjusting the time or changing batteries, make sure it is properly sealed. You can use silicone caulk or a similar waterproof sealant to seal any gaps around the clock mechanism. Apply the sealant carefully and let it dry completely.

3. Protect the Back of the Clock: The back of the clock is often vulnerable to water damage. Consider applying a waterproof sealant or outdoor-grade silicone caulk around the edges of the clock’s back cover. Ensure that the sealant creates a tight bond to prevent water from seeping inside.

4. Use a Weatherproof Casing: Consider placing the clock inside a weatherproof casing or enclosure. This can provide an additional layer of protection against rain, snow and other environmental elements. Ensure that the casing is transparent or has a clear front to allow you to see the clock face.

5. Mount the Clock in a Sheltered Area: Choose a location for the clock where it is less exposed to direct rainfall or harsh weather conditions. Mounting it under an eave or some form of shelter can significantly reduce its exposure to the elements.

6. Look after the Paint Work: Make sure the paintwork is in good condition to protect the materials beneath it. If there is exposed wood, make sure it’s varnished or waxed. 

7. Regular Maintenance: Periodically check the clock for any signs of wear or damage to the waterproofing measures. If you notice any cracks or gaps, reapply sealant or waterproofing as needed.

8. Manufacturer Guidelines: Remember to follow the specific guidelines provided by the manufacturer for your outdoor clock, as different clocks may have unique features and requirements.

9. Geography: Consider the local climate and weather conditions when choosing and maintaining your outdoor clock – is it fit for purpose?
