9 Steps on How to Install Cork Underlayment for Hardwood Floors

You Have to Follow These Nine Easy Steps for Installing Cork Underlayment:

Step 1: Measuring the Room

The first step is to measure the room where you will install the cork underlayment. You will need to know the room’s dimensions to determine how much underlayment you will need to purchase. This step is important because you don’t want to purchase too much or too little underlayment.

Measure the Room

Step 2: Purchase the Underlayment

Once you know how much underlayment you need, you can purchase it from a local home improvement store or online retailer. Be sure to select an underlayment that is specifically designed for hardwood floors. But remember that thicker underlayments will provide more sound and thermal insulation.

Step 3: Prepare the Room

Before you begin the installation, you must prepare the room where the underlayment will be installed. This includes removing any existing flooring, such as carpeting or vinyl tile. You will also need to remove any baseboards or trim. Once the room is cleared, you should clean the subfloor to remove any dirt or debris.

Step 4: Install the Underlayment

Now it’s time to install the underlayment. You will need to start in one corner of the room and unroll the underlayment as you go. Be sure to overlap the seams of the underlayment by at least 3 inches. Once you reach the other side of the room, you can trim off any excess underlayment. Ensure the entire floor is covered before moving on to the next step.

Step 5: Secure the Underlayment

After the underlayment is installed, you need to secure it in place. You can use tape or adhesive specifically designed for cork underlayment. Sometimes, the underlayment will come with a self-adhesive strip that you can use. Once the underlayment is secured, you can move on to the next step.

Secure It in Place

Step 6: Install the Flooring

Now that the underlayment is installed, you can install the hardwood flooring. This can be done by nailing or screwing the flooring into place. Safety Note: Be sure to wear a dust mask when working with wood to avoid inhaling dust particles.

Step 7: Add Molding

Once the flooring is installed, you can add molding around the room’s perimeter to make it look finished. You can go for a traditional look by adding baseboards or crown molding. Or you can get creative and add your unique style of molding. Most people prefer to install molding after the flooring is installed because it’s easier to do.

Step 8: Clean Up

After the installation is complete, you will need to clean up any debris or dust that is left behind. This can be done with a broom and dustpan or a vacuum cleaner. Be sure to thoroughly clean the room before moving on to the next step. Otherwise,  the room will not be ready for use.

Clean Up Any Debris or Dust

Step 9: Maintaining the Floor

Once the floor has been installed, it is important to maintain it properly to keep it looking its best. This includes sweeping and mopping the floor regularly. You can’t just use any old mop, though. Instead, you need to select a mop specifically designed for hardwood floors. Otherwise, you run the risk of damaging the floor.

If you are not comfortable installing the cork underlayment or hardwood flooring yourself, you can always hire a professional to do it for you. This will ensure that the job is done correctly and that your floors will last many years.

These are the steps for How to Install Cork Underlayment for Hardwood Floors. Be sure to follow them carefully to avoid any damage to your floors. With a little effort, you can have beautiful hardwood floors that add value to your home.

10 Things to Keep in Mind When Installing Cork Underlayment for Hardwood Floors

You must keep these ten things in mind when installing cork underlayment for hardwood floors:

  1. Read the manufacturer’s instructions carefully before beginning installation.
  2. Cork underlayment is typically sold in rolls or sheets.
  3. If using rolls, unroll and allow the cork to acclimate to the room temperature for 24 hours before installation.
  4. If using sheets, score the back of each sheet with a utility knife to make it easier to bend and fit around corners.
  5. Use a straightedge and sharp utility knife to cut the cork to size.
  6. Fit the cork underlayment snugly against the subfloor, starting at one corner of the room and working your way out.
  7. Use a roller or hand roller to press the cork into place and ensure good contact with the subfloor.
  8. Trim off any excess cork with a utility knife.
  9. Seal the seams between sheets of cork with tape or caulking.
  10. Allow the cork to dry thoroughly before installing hardwood flooring.

Do You Staple Down Cork Underlayment?

You may be wondering whether or not to staple down your cork underlayment. The answer is: it depends. If you’re installing the cork underlayment over a concrete subfloor, then stapling is generally unnecessary since the weight of the cork will keep it in place. However, if you’re installing the cork over a plywood subfloor, you may want to consider stapling it down to prevent movement. Ultimately, it’s up to you.

Does Cork Underlayment Need a Moisture Barrier?

Cork underlayment is an excellent choice for hardwood floors, as it is a natural, eco-friendly, and durable material. Cork also has unique properties that make it ideal for use as underlayment, including its ability to resist mold and mildew.

However, because cork is a natural material, it is important to take steps to protect it from moisture. While cork underlayment does not necessarily require a moisture barrier, it is always best to care to the side of caution and install one.

Moisture barriers are typically made of polyethylene or another waterproof material. They are placed between the subfloor and the cork underlayment and protect the cork from any moisture that might seep up from the subfloor.

Suppose you install cork underlayment in a room prone to high humidity or moisture (such as a bathroom or laundry room). In that case, it is especially important to install a moisture barrier.

What Happens If Cork Flooring Gets Wet?

Cork flooring is considered water-resistant, but it’s not completely waterproof. So, if cork flooring gets wet, it can cause damage to the flooring, especially if water seeps into the cracks and crevices between the tiles. In some cases, wet cork flooring can lead to warping, mold growth, and a musty smell.

It is essential to clean up any spills or water damage immediately, wipe the surface dry and air the room to prevent moisture from being trapped in the room. When cleaning cork flooring, it’s important to use a damp mop rather than a soaking wet mop and avoid using abrasive cleaning substances that can damage the surface. In sum, it’s best to prevent moisture on cork flooring as much as possible and clean up any spills as soon as they happen.

How Be Thick Should Cork Underlay?

Installing cork underlayment is a great way to improve the acoustics and insulation of your hardwood floors. But how thick should cork underlay be?

Typically, cork underlayment comprises 1/4 inch (6 mm) to 1/2 inch (12 mm). The thicker the underlayment, the better the sound insulation and impact absorption it will provide.

If you are installing cork underlayment over a concrete subfloor, we recommend using a thicker underlayment of at least 1/2 inch (12 mm). This will help to minimize any potential cracking of your hardwood floors due to differential settling.

If you are installing cork underlayment over a wood subfloor, you can use a thinner underlayment of 1/4 inch (6 mm). However, if you are concerned about noise transmission, you may want to use a thicker underlayment to help reduce sound travel.

What is One Major Drawback to Cork Flooring?

One major drawback to cork flooring is its susceptibility to water damage. Despite being a sustainable and durable flooring option, cork is not waterproof, and any water or moisture that seeps into the seams or cracks in the cork can cause it to warp and potentially lead to mold growth.

Cork flooring also requires proper sealing and maintenance to prevent water damage, which can add to its cost and upkeep. Additionally, cork flooring is not as resistant to scratches and dents as some other flooring materials and may require regular sanding and resealing to maintain its appearance. Despite these drawbacks, cork flooring remains popular for those seeking an eco-friendly and comfortable option.

Do You Need Underlayment for Cork Flooring?

Yes, underlayment is required for cork flooring. Cork flooring is less dense than most other flooring materials, which makes it more susceptible to impacts and moisture. A quality underlayment helps add cushioning, protect against moisture, and provide stability to the floor. The underlayment helps absorb and distribute the weight placed on the floor, preventing it from shifting or settling over time.

Additionally, underlayment can provide acoustic insulation, which can help reduce room noise levels. When choosing an underlayment for cork flooring, it is important to select a product specifically designed for cork flooring use. Look for an underlayment that is moisture-resistant, provides good sound-deadening properties, and is easy to install.


Cork is a good insulator, so it can help keep your floor warm in the winter and cool in the summer. It also has natural noise-canceling properties, so it can help reduce sound transmission between floors. This makes cork an ideal material for use in an apartment or other multi-unit dwelling.

Installing cork underlayment for your hardwood floors is an easy process that can provide many benefits. If you are considering new flooring for your home, be sure to consider using cork as your underlayment option!
