How To Install Underlayment For Laminate Flooring On Concrete

Laminate flooring is a popular choice for homeowners due to its durability, affordability, and ease of maintenance. While the installation process is relatively straightforward, it’s crucial to install underlayment before laying the laminate planks. This layer provides essential cushioning, soundproofing, and moisture protection, ensuring a comfortable and long-lasting floor. Here's a comprehensive guide on installing underlayment for laminate flooring on a concrete subfloor.

Choose the right underlayment

The type of underlayment you choose will depend on your specific needs and the characteristics of your concrete subfloor. There are several types of underlayment available, each with its own advantages and disadvantages.

Foam underlayment is a common and affordable option, offering good cushioning and sound absorption. It can be found in various thicknesses and densities, with higher densities providing better insulation and support.

Cork underlayment is known for its excellent sound absorption and moisture resistance. It's a natural and sustainable material that can add a touch of warmth to the floor.

Rubberized underlayment is a durable and long-lasting option, providing superior impact resistance and sound absorption. It's often favored in high-traffic areas.

Combination underlayment combines different materials, such as foam and rubber, to offer a comprehensive solution that addresses multiple needs.

When choosing underlayment, consider factors like the thickness of the laminate flooring, the level of sound absorption required, and the moisture levels in your home. Consult a flooring specialist or the manufacturer's instructions for guidance on the appropriate type and thickness of underlayment for your project.

Prepare the concrete subfloor

Before installing underlayment, ensure the concrete subfloor is clean, level, and dry.

Clean the subfloor: Sweep or vacuum the concrete subfloor to remove any debris, dirt, or dust. You might need a damp mop to clean up any spills or stains.

Inspect for cracks or other damage: Examine the subfloor for any cracks, chips, or uneven areas. Repair any significant damage with concrete patching material or contact a professional concrete contractor for assistance.

Level the subfloor: While a slight slope is acceptable, significant unevenness can affect the installation of the laminate flooring. You can use a self-leveling underlayment to address minor imperfections. However, for larger discrepancies, consider consulting a professional to ensure a properly leveled subfloor.

Moisture barrier: In areas prone to moisture, install a moisture barrier on top of the concrete subfloor. This can be a thick plastic sheet or a specialized vapor barrier. This will protect the laminate flooring and underlayment from moisture damage.

Install the underlayment

Once the subfloor is prepared, you can begin installing the underlayment. The installation process varies depending on the type of underlayment used.

Foam underlayment typically comes in rolls. Unroll the material along the wall, starting from the shortest side of the room. Ensure the seams are staggered and overlap by at least 12 inches. Use a utility knife or a pair of scissors to cut the material to size. Secure the underlayment to the subfloor using staples or tack strips.

Cork and rubberized underlayment might be available in rolls or tiles. The installation process for both typically involves securing the underlayment using staples or tack strips, depending on the manufacturer's instructions.

Regardless of the underlayment type, always ensure a smooth and consistent surface, avoiding wrinkles, bumps, or gaps. These imperfections can affect the installation of the laminate flooring and lead to unevenness or noise.

Final considerations

After installing the underlayment, you can proceed with the installation of the laminate flooring. Remember to choose the appropriate type and thickness of underlayment for your needs and consult the manufacturer's instructions for specific installation guidelines.

Installing underlayment is an essential step in ensuring a successful laminate flooring installation. It provides essential cushioning, soundproofing, and moisture protection, making your floor comfortable, quiet, and durable. Following these steps will help you install underlayment effectively and ensure a long-lasting and beautiful floor.
