How To Use Flex Seal Draft Tape
Flex Seal Draft Tape is designed to stop cold air fast by sealing gaps around doors, windows, and more. This clear, flexible, weatherproof strip creates an airtight barrier while still allowing doors and windows to open and close normally. Best of all, it can be applied in seconds with no mess. Follow these steps to achieve the best results when using Flex Seal Draft Tape.
How to Use Flex Seal Draft Tape
1. Gather Your Supplies
• Flex Seal Draft Tape
• Scissors
• Measuring tape
2. Clean and Prep the Surface
Wipe down the area you plan to seal. Remove dirt, dust, grease, and moisture. On glass or metal, use a household cleaner for best results.
3. Measure, Cut, and Dry Fit
Measure the length of the gap, then cut a strip of Flex Seal Draft Tape to size. Before peeling the backing, do a “dry fit” by placing the tape where you plan to install it and checking that the flexible flap touches the surface without bending too much.
4. Press and Seal
Once placement is set, peel off the backing and press the tape firmly into place for 15–30 seconds. This ensures strong adhesion, even in freezing temperatures.
5. Remove or Reuse
When spring arrives, peel the tape away slowly. It removes cleanly without leaving a sticky mess. To reuse, rinse with water, let it air dry, and store in a sealed plastic bag in a cool, dry place.
How to Seal Doors
Doors That Open Inward
Bottom Gap: Attach Flex Seal Draft Tape to the inside bottom of the door. The flexible flap should gently sweep the floor when the door moves.
Top Gap: Apply the tape along the inside top edge of the door, flap facing down to cover the gap.
Sides with Hinges: Measure each side gap. You may need to cut the tape into smaller sections to fit around hinges. Press firmly to secure.
Doors That Open Outward
Bottom Gap: Just like inward-opening doors, attach the tape to the inside bottom of the door.
Top and Sides: Instead of attaching to the door, apply Flex Seal Draft Tape directly to the frame. This ensures the flap seals tightly while still letting the door move freely.
How to Seal Windows
Flex Seal Draft Tape also works on windows, including sliding models. Measure the gap, cut the tape, dry fit, then peel and stick. The flap should cover the draft point without interfering with how the window opens or closes.
Best Practices For Using Flex Seal Draft Tape
- Choose smooth, non-porous surfaces: Flex Seal Draft Tape works best on glass, wood, metal, tile, plastic, or fiberglass. Avoid painted walls, wallpaper, or drywall.
- Always dry fit first: Check placement before sticking for the best seal.
- Press firmly: Hold for 15–30 seconds to create a secure bond.
- Focus on problem areas: Drafty windows, basements, or doors that lead to the outside.
- Store properly: Keep leftover tape in a cool, dry environment to use again next winter.
With Flex Seal Draft Tape, you can stop icy drafts in their tracks, keep your home warmer, and reduce heating costs. It’s a simple and fast solution that helps you take on winter with confidence.
