When freezing temperatures hit, water can seep into small cracks and expand as it turns to ice, causing concrete, wood, and other materials to break apart. After the thaw, you're often left with deep holes or wide gaps that need to be sealed fast. The good news is that Flex Paste can be used to fill deep holes created by freeze expansion.

Filling Deep Holes with Flex Paste

Flex Paste is a thick, rubberized paste designed to seal, patch, and protect surfaces, even in extreme conditions. Its heavy-duty formula adheres to a wide range of materials, including concrete, brick, wood, and more, making it a great option for filling holes caused by freeze-thaw cycles.

It can be applied directly into deep cracks or holes using a putty knife or gloved hand. The paste remains workable for several minutes before it starts to skin over, giving you enough time to shape and smooth it as needed.

Tips for Dealing with Deeper Damage

• Work in layers: For very deep holes, apply Flex Paste in thin layers, allowing each layer to cure for 24 hours before adding the next. This prevents soft spots and ensures a strong, flexible seal throughout.
• Clean before you seal: Remove any loose debris, dust, or moisture. This helps with adhesion and durability.
• Use in all seasons: Flex Paste can be applied in cold weather (down to 0°F) and remains flexible once cured.

Flex Paste can be used to fill deep holes created by freeze expansion. Just make sure to prep the area and allow proper curing between layers. Its strong, flexible finish withstands weather changes, moisture, and more, making it a reliable fix for seasonal surface damage. To learn more about Flex Paste, download our Product Reference Guide.
