Help Prevent Winter Damage with the Flex Seal Family of Products

Winter weather can be harsh on your home, causing drafts, leaks, and other damage. Preparing ahead of time not only helps prevent costly repairs but can also make your home more comfortable and energy-efficient throughout the season.

With the Flex Seal Family of Products, you can handle common winter repairs quickly, effectively, and without expensive tools.

Why These Winter Repairs Matter

Winterizing your home isn’t just about comfort — it’s about protecting your investment. Sealing drafts, repairing gutters, and patching leaks can:

Reduce heating costs by improving insulation
Prevent water damage from snow, ice, and rain
Extend the life of windows, gutters, and plumbing
Save time and money on emergency repairs

Here are three key fixes you can make with Flex Seal products to keep your home protected from the elements.

Important Safety Information: Before using Flex Seal products, read all directions carefully and follow safety precautions such as wearing protective gear and applying products in a well-ventilated area.

1. Caulk Drafty Windows with Flex Shot

Drafty windows aren’t just uncomfortable — they can drive up your heating bill all winter long. A simple bead of Flex Shot creates a waterproof, airtight seal that blocks cold air from sneaking inside.

Steps:

Prepare the Surface – Make sure the window frame is clean, dry, and free from dirt, grease, or oil. A clean surface ensures maximum adhesion.
Apply Flex Shot – Hold the can at a 45-degree angle, press the nozzle, and apply Flex Shot directly to the gap or crack. Apply in a slow, steady motion for a perfect bead and adjust your speed to control bead thickness.
Smooth it out: Use your finger right after application to smooth out Flex Shot for a clean, professional finish.
Clean Excess Product – Wipe away any extra sealant with a dry paper towel before it starts to set.
Let It Set – A tacky film will form in about 20 minutes and dry to the touch over time. Allow 24 to 48 hours (depending on temperature and humidity) for Flex Shot to cure completely.

Flexpert Tip: Flex Shot’s extension tube can be cut to any size to produce the desired bead thickness. Use a razor blade to cut the tube at a 45-degree angle. The lower you cut, the larger the bead size.

2. Seal Gutters with Flex Seal Spray

Clogged or leaky gutters can lead to water damage, ice buildup, and costly repairs. Using Flex Seal Spray helps waterproof your gutters and stop small leaks before they become bigger problems.

Steps:

Clear the Gutter—Remove any dirt or debris, flush the gutter with a hose, and dry thoroughly. For extra safety, have someone hold your ladder steady during this process.
Mask the Edges – Add painter’s tape along the gutter edges to prevent overspray.
Shake the Can – Shake Flex Seal Spray for at least 30 seconds to ensure an even mixture.
Apply Flex Seal – Hold the can about 8–12 inches away from the surface and spray in a steady, sweeping motion, slightly overlapping each pass.
Let it Dry and Apply Additional Coats– Let the first coat dry for 24 hours before adding another. Full curing may take up to 48 hours.

Flexpert Tip: We recommend applying Flex Seal Spray in multiple thin layers rather than one thick layer.

3. Patch Leaky Pipes Fast with Flex Tape

Burst or leaking pipes can be a homeowner’s nightmare. Flex Tape can provide a quick, strong, waterproof patch until a full repair can be made.

Steps:

Prepare the Area – Make sure the surface is clean, smooth, and free from grease, oil, dirt, or debris.
Cut the Tape – Using a razor blade, cut Flex Tape into a patch larger than the leak.
Apply the Tape – Remove the transparent backing and press Flex Tape firmly over the leak. Remember: once it sticks, it cannot be repositioned.
Smooth Out Air Pockets – Starting at the center, press firmly with your fingers or a squeegee, moving toward the edges to remove any air bubbles or trapped water. Then, hold firm pressure for at least one minute to help the adhesive bond.

Flexpert Tip: Flex Tape is designed for a strong, waterproof hold, but should not be used on high-pressure applications like garden hoses or engines. Always replace damaged sections of pipe as soon as possible.
