3. Installation Instructions
Installation of the Hormann threshold seal is designed to be straightforward and does not require complex modifications. The kit includes all necessary mounting hardware and detailed instructions to facilitate quick and effective sealing.
- Prepare the Surface: Ensure the garage floor where the seal will be installed is clean, dry, and free from dust, grease, or debris. A clean surface is crucial for proper adhesion.
- Position the Seal: Close the garage door. Place the threshold seal on the floor directly under the garage door, ensuring it is centered and aligned with the door's bottom edge. The seal should create a tight fit when the door is closed.
- Mark the Position: Once the seal is correctly positioned, use a pencil or marker to trace its outline on the garage floor. This will serve as a guide for adhesive application and drilling.
- Apply Adhesive: Apply the provided adhesive/sealant within the marked area on the floor. Follow the adhesive manufacturer's instructions for application thickness and curing time. Ensure even coverage to create a strong bond and watertight seal.
- Place the Seal: Carefully place the threshold seal onto the applied adhesive, aligning it with the marked outline. Press firmly along the entire length of the seal to ensure good contact with the adhesive.
- Secure with Screws (Optional but Recommended): For enhanced durability and security, drill pilot holes through the designated areas of the seal and into the garage floor, following the marked positions. Insert the provided wall plugs and secure the seal with screws.
- Curing Time: Allow the adhesive to cure completely before operating the garage door or exposing the seal to heavy traffic or moisture. Refer to the adhesive instructions for specific curing times.

4. Care and Maintenance
To ensure the longevity and continued effectiveness of your Hormann Garage Door Threshold Seal, follow these simple maintenance guidelines:
- Regular Cleaning: Periodically clean the seal and the surrounding floor area to remove dirt, leaves, and other debris that may accumulate. Use mild soap and water, then rinse thoroughly.
- Inspect for Damage: Regularly inspect the seal for any signs of wear, cracks, or damage. If damage is observed, consider replacement to maintain optimal protection.
- Check Adhesion: Occasionally check that the seal remains firmly adhered to the floor. If any sections appear loose, reapply adhesive as needed to prevent water ingress.
