Flex Seal Spray is designed to withstand a variety of weather conditions, including cold temperatures, but certain surface conditions can affect its adhesion. If the surface is still cold after snow or ice has melted, it may affect bonding and cure time, especially if moisture remains.

Tips for Cold Surface Application

Flex Seal Spray can be applied to surfaces down to 0°F, but keep in mind that colder surfaces can slow the curing process.

If you're working with a recently thawed area:

• Dry the surface thoroughly.
• Wait for a warmer part of the day, when possible.
• Store the can indoors before use to keep the spray at an optimal temperature.
• Avoid shaded or frost-prone areas where cold can linger even after air temperatures rise.

Flex Seal Spray can help coat, seal, and protect during spring thaw and beyond. To learn more about Flex Seal, check out our FAQs.
