How to install laminate wood flooring
Installing laminate wood flooring involves preparing the subfloor, acclimating planks, laying them using a click-lock system, and finishing edges. You’ll need to ensure proper subfloor conditions, account for expansion gaps, and use tools like a tapping block and saw. Careful planning and execution yield a durable, attractive floor.
Installing laminate wood flooring yourself is a rewarding project that can significantly update your home’s appearance and value. Unlike solid hardwood, laminate is a manufactured product designed to mimic wood’s look. It consists of a composite core, a decorative layer (the wood-look print), and a clear protective wear layer. Most modern laminate flooring uses a click-lock system, making installation accessible for DIYers.
Before you begin, gather your tools and materials. You’ll need the laminate planks, underlayment (often required by the manufacturer and provides cushioning and moisture barrier), a measuring tape, a utility knife, a tapping block, a pry bar, a jigsaw or miter saw for cuts, safety glasses, and a pencil. Ensure you have enough planks, accounting for about 10% extra for cuts and waste.
Prepare the subfloor
The subfloor must be clean, dry, and level. Sweep or vacuum thoroughly to remove all debris. Uneven subfloors can cause the laminate to shift or the locking system to fail. For minor imperfections, a self-leveling compound can be used. Check for moisture; if you’re installing over concrete, a moisture barrier is essential, often integrated with the underlayment. Remove any existing baseboards or trim that will be in the way. You can reattach them later, leaving a small gap at the bottom to accommodate the flooring.
Acclimate the laminate flooring
Laminate planks need to acclimate to the room’s temperature and humidity for at least 48 hours before installation. Store them flat in the room where they will be installed. This prevents expansion or contraction issues after the floor is laid. Check the manufacturer’s specific acclimation guidelines, as some may require longer periods.
Install the underlayment
Roll out the underlayment according to the manufacturer’s instructions. It typically comes in rolls and is laid directly over the subfloor. If your underlayment requires a separate moisture barrier, ensure it’s installed first, overlapping seams and taping them to create a continuous seal. Some underlayments have a built-in vapor barrier. Do not overlap the underlayment unless specified by the manufacturer; butt the edges together.
Lay the first row of planks
Start in a corner, typically the one furthest from the door. Place the first plank with the tongue side facing the wall. Leave a 1/4-inch to 1/2-inch expansion gap between the plank and the wall. You can use spacers for this. If your planks have a beveled edge, ensure the bevel faces the wall. Engage the long edge of the next plank into the long edge of the first plank, then use the tapping block and hammer to gently tap the short ends together until they are flush. Work your way across the room, ensuring each plank is tightly connected.
Cut planks for the end of rows
When you reach the end of a row, measure the remaining space. You’ll likely need to cut a plank to fit. Measure carefully, remembering to account for the expansion gap. You can use a miter saw for straight cuts or a jigsaw for more intricate cuts, like around door frames. Use the offcut from this cut to start the next row, provided it’s at least 8-10 inches long. This creates a staggered or offset pattern, which adds strength and visual appeal to the floor. A minimum 6-inch offset is generally recommended.
Install subsequent rows
Start the second row with the cut piece from the first row (if long enough). Angle the tongue of the second plank into the groove of the first plank in the previous row. Once engaged along the long edge, tap the short end to secure it. Continue laying planks across the room, ensuring a tight fit. Stagger the end joints between rows by at least 6 inches for stability and aesthetics. Use the tapping block on the long edge as well, if necessary, to ensure a tight seam.
Install the final row
The last row often requires cutting planks lengthwise. Measure the distance from the installed flooring to the wall, again accounting for the expansion gap. You might need to rip the planks using a table saw. To install the last row, you may need to cut off the tongue on the side that faces the wall. Then, angle the remaining tongue into the groove of the previous row and use the pry bar to gently pull the planks into place, securing them to the previous row.
Install trim and finish
Once the flooring is installed, reattach your baseboards and trim. Nail them to the wall, not the floor, to allow for expansion. If installing quarter-round molding, it should cover the expansion gap. Install transition strips in doorways or where the laminate meets another flooring type to create a smooth transition. Clean the floor with a damp mop and approved laminate cleaner.
Common Mistakes When Installing Laminate Flooring
| Step or Tool | Typical Mistake | Consequence |
|---|---|---|
| Subfloor Preparation | Not ensuring the subfloor is clean, dry, and level | Laminate can squeak, warp, or the locking system can break. |
| Acclimation | Skipping or shortening the acclimation period | Planks can expand or contract after installation, causing gaps or buckling. |
| Expansion Gaps | Not leaving adequate expansion gaps around the perimeter | The floor will buckle or warp when temperature and humidity change. |
| Tapping Block | Using a hammer directly on planks or not using a tapping block | Damage to the edges and locking mechanism of the planks. |
| Staggering Joints | Aligning the end joints of planks in adjacent rows | Weakens the floor structure and looks unprofessional. |
FAQ
How to install laminate flooring on wood floor
You can install laminate flooring directly over an existing wood subfloor, provided it is clean, dry, and level. Ensure there are no loose boards, and secure any that are creaky or uneven. A moisture barrier and appropriate underlayment are crucial, especially if the wood subfloor is in contact with concrete or exposed to moisture.
Can I install laminate flooring over tile?
Yes, you can often install laminate flooring over existing tile, as long as the tile floor is level and in good condition. Ensure the grout lines are filled to create a smooth surface. A moisture barrier and suitable underlayment are still necessary for proper installation and to prevent moisture issues.
What are the minimum expansion gap requirements for laminate flooring?
Most manufacturers recommend a minimum expansion gap of 1/4 inch to 1/2 inch around the entire perimeter of the room, including walls, cabinets, and fixtures. This gap allows the laminate to expand and contract with changes in temperature and humidity without buckling.
