Installing Laminate Flooring Over Plank Subfloor

Laminate flooring can be installed over a plank subfloor. Ensure the subfloor is clean, level, and dry. Acclimate the laminate, use a moisture barrier, add a foam underlayment, and follow the manufacturer’s instructions for a successful installation.

Installing laminate flooring over a plank subfloor can be a rewarding DIY project, transforming the look of your space. This comprehensive guide will walk you through the step-by-step process, ensuring a successful and durable installation.

Step 1: Subfloor Preparation

Ensure that the plank subfloor is clean and free of any debris, such as dust, dirt, or remnants of previous flooring. Repair any noticeable damage or irregularities in the subfloor, as these can affect the stability of the laminate flooring. Use a leveling compound if necessary to create a flat surface. It’s crucial to make sure the subfloor is completely dry before proceeding with the installation to prevent any moisture-related issues.

Step 2: Acclimation of Laminate Planks

Unpack the laminate planks and allow them to acclimate to the room where they will be installed for at least 48 hours. This process helps the planks adjust to the temperature and humidity conditions of the space, minimizing the risk of expansion or contraction after installation. Keep the planks in their original packaging during acclimation and store them in the center of the room.

Step 3: Moisture Barrier Installation

Install a moisture barrier over the prepared plank subfloor. This barrier is typically a thin layer of plastic or specialized underlayment that protects the laminate flooring from potential moisture seepage from the subfloor. Securely tape the seams to ensure a continuous barrier, and trim any excess material along the edges of the room.

Step 4: Foam Underlayment Placement

Lay down a foam underlayment over the moisture barrier. This underlayment serves several purposes, including providing sound absorption to reduce noise, acting as a cushioning layer for a comfortable feel underfoot, and smoothing out minor imperfections in the subfloor. Roll out the underlayment, ensuring that seams are staggered and taped for a secure fit.

Step 5: Beginning the Installation

Start the installation process according to the manufacturer’s guidelines. Typically, laminate flooring is designed to click and lock into place. Begin in one corner of the room and work your way across, connecting each plank as you go. Make sure to maintain the expansion gap recommended by the manufacturer around the perimeter of the room.

Step 6: Spacers for Gap Maintenance

Place spacers along the edges of the room to maintain the required expansion gap. These spacers ensure that the laminate flooring has enough space to expand and contract with changes in humidity. Commonly, manufacturers recommend a gap of 1/4 to 1/2 inch, but refer to the specific guidelines provided with your laminate flooring.

Step 7: Cutting and Staggering Planks

As you approach the edges of the room or encounter obstacles like door frames, you’ll likely need to cut laminate planks to fit. Use a circular saw, jigsaw, or handsaw, depending on the situation, and be sure to wear appropriate safety gear. Additionally, stagger the seams of the laminate planks, avoiding a repetitive pattern. Staggering helps distribute weight and enhances the stability of the flooring.

Step 8: Completion and Finishing Touches

Complete the installation, ensuring that all laminate planks are securely in place. Trim any excess foam underlayment using a utility knife. Install molding, such as baseboards or quarter round, around the perimeter of the room to cover the expansion gap and provide a polished finish. If transitioning to another type of flooring, use transition strips to create a seamless and visually appealing connection between the different surfaces.

Installing laminate flooring over a plank subfloor is a manageable DIY project with the right tools and careful execution. Following these steps will help you achieve a professional-looking result that enhances the aesthetic appeal of your space. Always refer to the specific guidelines provided by the laminate flooring manufacturer for optimal results and warranty adherence.
