STEP 1. Assess the Existing Hardwood Floor Condition

Inspecting the existing hardwood floor is crucial to ensure that engineered hardwood installation can be done. You should thoroughly check for any signs of damage, such as rot, cupping, or warping, as these issues must be addressed before proceeding with the installation.

Make sure the existing floor is flat, clean, dry, structurally sound, and free of squeaks. Also, ensure there are no protruding fasteners or nails, as they can cause problems during the installation process. Make sure the existing floor is in good shape before you install the engineered hardwood.

STEP 2. Prepare the Subfloor:

Now that the existing hardwood floor has been assessed, let’s prepare the subfloor for the new flooring like a chef preparing a canvas for a masterpiece dish. The subfloor preparation is crucial to ensure the longevity and stability of the new flooring.

Clean the hardwood floor thoroughly to remove dirt, debris, or adhesive residue. Use a vacuum cleaner or a broom and dustpan. Then check for any loose or damaged boards and fix them. Hammer down any protruding nails or screws and replace any damaged boards.

You can sand the existing hardwood floor lightly to create a rough surface for the adhesive to bond with. Then apply a primer or a sealer to the existing hardwood floor to prevent moisture from seeping through and causing damage to the new flooring.

STEP 3. Level the Existing Floor:

To achieve a flat surface for the new flooring, analyze the level of the current hardwood floor. Use a level to identify any humps or depressions. Once you have identified the problem areas, sand down any high spots on the floor and fill in the low spots with a suitable patching compound.

This process is essential to ensure the existing surface is flat and smooth, providing a suitable base for installing the engineered hardwood. By taking the time to level the existing floor, you can avoid any potential problems, such as unwanted gaps or unevenness, that could arise during the installation process.

STEP 4. Acclimate the Engineered Hardwood:

Before laying down the new flooring, ensure the engineered hardwood has had time to adapt to the room’s temperature and humidity for at least 72 hours. This lets it settle into new surroundings like a cozy sweater on a brisk autumn day.

This step is crucial as it reduces the risk of expansion or contraction after installation. During this acclimation process, keep the flooring in the room where it will be installed, and ensure that the temperature and humidity levels are consistent with the room’s typical conditions.

STEP 5. Lay Down Underlayment (if necessary):

Installing an underlayment over your existing hardwood floor is a necessary step when laying engineered hardwood on top. The underlayment helps reduce noise and create a barrier between the two flooring layers, preventing any moisture from seeping through and causing damage.

Choosing the right underlayment for your specific flooring needs, as different types offer different levels of sound reduction and moisture protection. Be sure to follow the manufacturer’s instructions when installing the underlayment.

STEP 6. Create a Gap between Wall and Planks:

Using spacers along the walls creates a gap between the first row of planks and the wall, allowing for natural expansion and reduction of the flooring. This step is crucial when installing engineered hardwood over an existing hardwood floor.

The gap is necessary because the underlayment and the new planks will raise the height of the floor, restricting the movement of the original flooring. Without this gap, the flooring could buckle, warp, or develop gaps.

The spacers should be placed every 12-18 inches along the walls, and their size should be determined by the planks’ thickness and the room’s dimensions. A professional installer will know how to properly use spacers to create the right gap size for your specific flooring project.

STEP 7. Install the First Row:

Now it’s time to lay down those planks and bring your vision to life. Make sure you secure them tightly with either nails or a Brad nailer.

Begin in the corner of the room and lay the first row of engineered hardwood planks, ensuring they are firmly attached and level. To do this, use either nails or a Brad nailer to secure the planks to the subfloor.

As you work your way across the room, continue to check that the planks are level and that they are aligned correctly. Remember, the first row is crucial to the success of your flooring project, so take your time and ensure everything is done correctly.

STEP 8. Install Subsequent Rows:

After securing the first row, it’s time to continue the installation by overlapping and tapping together subsequent rows with a rubber mallet and tapping block. It’s important to take care and maintain a snug fit between the planks. This will create a uniform and visually appealing installation.

By overlapping the locking edges of the planks, you can ensure that the installation is secure and won’t come apart over time. Using a rubber mallet and tapping block is essential to prevent damage to the planks during installation.

With these tools and techniques, you can confidently install engineered hardwood over existing hardwood and achieve a beautiful and long-lasting result.

STEP 9. Nail the Hardwood Planks:

To make sure the planks stay put, hammer nails into the tongue of each plank at an angle. This ensures a tight fit and creates a secure hold lasting for years.

Follow the manufacturer’s instructions and your personal preference for securing subsequent rows. Though adhesive can be used instead of nails, nailing the planks together is a traditional and reliable method for installation.

Be sure to use the recommended size and type of nail and space them appropriately. A nail gun can also be used for efficiency and precision. Remember to take precautions, such as wearing safety goggles and ear protection, when using a hammer or nail gun.

STEP 10. Trim and Make Special Cuts:

Make the installation process even more precise and customized by using an oscillating saw, jigsaw, or miter saw to make special cuts for AC vents, cabinet angles, and door casings. These areas may require specific cuts that aren’t possible with standard flooring tools.

Use the right tool to ensure a seamless and professional-looking finish. When making cuts for AC vents or cabinet angles, an oscillating saw or jigsaw can provide the necessary precision. A miter saw may be necessary for door casings to allow the new flooring to slide underneath.

STEP 11. Address Transition Areas:

Addressing transition areas is crucial for achieving a seamless finish in your engineered hardwood flooring installation. When your new flooring meets other types of flooring or changes direction, transition pieces may be necessary.

These pieces should be installed according to the manufacturer’s instructions to ensure a professional and polished look. Before installing the transition pieces, properly trim and make any special cuts. Also, ensure the transition pieces are securely fastened to prevent movement or gaps.

STEP 12. Install the Final Row:

Now it’s time to tackle the final row of engineered hardwood installation. Use a table saw to cut the planks to fit the remaining space while maintaining a consistent and visually pleasing appearance.

Here are some tips to keep in mind:

• To avoid making mistakes, measure twice and cut once.
• Use a straight edge or guide to ensure accurate cuts.
• Double-check the width of the plank before cutting, as different rows may have slightly different widths.
• Remember to use safety equipment, such as goggles and ear protection, when operating the table saw.

STEP 13. Remove Spacers and Install Trim:

After completing the installation, it’s time to give your floors a finished look by removing the spacers and adding baseboard trim or quarter-round. This step is important as it not only enhances the appearance of your floors but also covers the expansion gap left by the spacers.

The baseboard trim or quarter round should be installed along the walls, ensuring a snug fit with the flooring. You can use a finish nailer or adhesive to secure the trim.

Leaving the expansion gap uncovered can cause the floor to buckle or warp over time. Therefore, removing the spacers and installing the trim is a crucial step in the installation process.

What to Consider When Installing Engineered Hardwood over Existing Hardwood Flooring?

Before installing engineered hardwood over existing hardwood flooring, there are several key points to consider.
