As the ground warms and expands during spring thaw, outdoor surfaces like siding, trim, or concrete joints may develop new cracks or separations. Flex Caulk is a great option for sealing those gaps caused by shifting soil.

Why Flex Caulk Works for This:

• Provides a flexible, waterproof seal that moves with surfaces
• Available in Hybrid and 100% Silicone formulas for different needs
• Stays durable through seasonal temperature swings and moisture exposure

Choosing the Right Formula:

• Hybrid: Can be applied to wet or dry surfaces and is paintable—ideal if the area is damp from melting snow or rain.
• Silicone: Offers extreme UV and temperature resistance but must be applied to dry surfaces.

Before applying, remove any old caulk or debris and dry the area as much as possible (especially when using the silicone formula).

Flex Caulk helps you stay ahead of seasonal damage by sealing shifting gaps and preventing water from sneaking in where it doesn't belong. To learn more about Flex Caulk, download our Product Reference Guide.
