How To Install An Interior Door Threshold On Concrete

Installing an interior door threshold on concrete requires careful planning and precise execution. By following the steps outlined in this guide, you can ensure that your new threshold is securely installed and complements the aesthetics of your home.

Materials Required:

Interior door threshold
Concrete adhesive
Concrete screws
Drill
Screwdriver
Level
Utility knife

Steps:

1. Measure and Cut the Threshold:

Measure the width of the doorway opening. Cut the threshold to the measured width using a utility knife.

2. Prepare the Concrete Surface:

Clean the concrete surface where the threshold will be installed. Remove any dirt, debris, or old adhesive. Allow the surface to dry thoroughly.

3. Apply Concrete Adhesive:

Apply a generous bead of concrete adhesive to the underside of the threshold. Ensure that the adhesive is evenly distributed.

4. Position and Secure the Threshold:

Place the threshold on the prepared concrete surface, aligning it with the edges of the doorway opening. Use a level to ensure that the threshold is level. Secure the threshold using concrete screws. Drill pilot holes before driving the screws to prevent cracking the concrete.

5. Fill the Gaps:

Use a utility knife to cut strips of foam or cork to fill the gaps between the threshold and the concrete. Insert the strips into the gaps to create a tight seal.

6. Seal the Joints:

Apply a bead of caulk along the joints between the threshold and the concrete. Use a caulk gun to ensure a neat and even application.

7. Allow the Adhesive to Cure:

Refer to the manufacturer's instructions for the concrete adhesive regarding the curing time. Allow the adhesive to cure completely before using the door.

Tips:

Choose a threshold made of high-quality materials that can withstand wear and tear.
Use a concrete adhesive specifically designed for bonding to concrete.
Ensure that the threshold is level and securely fastened to prevent shifting.
Fill all gaps between the threshold and the concrete to prevent moisture penetration.
If the concrete surface is uneven, use a self-leveling compound to create a smooth surface before installing the threshold.

Conclusion:

By following these steps, you can successfully install an interior door threshold on concrete. This will not only enhance the aesthetics of your home but also provide a secure and moisture-resistant transition between the doorway and the concrete floor.
