How to lay laminate wood flooring
Laying laminate wood flooring involves preparing the subfloor, acclimating the planks, installing the first row with spacers, clicking subsequent rows together, and finishing with trim. Proper subfloor prep and expansion gaps are crucial for a durable, professional-looking installation.
Laying laminate wood flooring is a manageable DIY project that can dramatically update your home’s appearance. The key to a successful installation lies in careful preparation and understanding the click-lock system of the planks. You’ll be working with a floating floor system, meaning the laminate isn’t directly attached to the subfloor but rather locks to itself, allowing for expansion and contraction with temperature and humidity changes.
Before you begin, ensure you have all the necessary tools and materials. This includes the laminate planks, underlayment, vapor barrier (if required), a measuring tape, a tapping block, a pull bar, a saw (miter saw, jigsaw, or circular saw), a utility knife, safety glasses, gloves, a pencil, spacers, and trim pieces like baseboards or quarter-round molding.
Prepare your subfloor
A smooth, clean, and level subfloor is critical for a good laminate installation. Start by removing all existing flooring, including carpet, vinyl, and any adhesive residue. Sweep and vacuum the subfloor thoroughly. Check for high spots or low spots. High spots can be sanded down, while low spots might need to be filled with a leveling compound. The subfloor should be reasonably flat; typically, a variation of no more than 1/8 inch over a 6-foot span is acceptable, as per manufacturer guidelines and general building practices.
Most laminate flooring requires a vapor barrier, especially if installed over concrete or in basements. Lay down the plastic sheeting, overlapping seams by at least 6 inches and taping them. If your laminate has a pre-attached underlayment, a vapor barrier may still be necessary depending on the manufacturer’s instructions and your subfloor type. Roll out the underlayment, cutting it to fit the room and butting the seams together, taping them if recommended by the underlayment manufacturer.
Acclimate the laminate planks
Laminate planks need to adjust to the temperature and humidity of the room where they will be installed. This process, called acclimation, prevents excessive expansion or contraction after installation. Store the unopened boxes of laminate flooring flat in the room for at least 48-72 hours, or as recommended by the manufacturer. Do not open the boxes or lean them against walls during this period.
Plan your layout
Determine the direction of your first row. It’s common to lay planks parallel to the longest wall in the room or in the direction of the main light source. This can make the room appear larger. Calculate the number of planks needed by measuring the room’s square footage and adding 5-10% for waste, cuts, and mistakes. You’ll need to account for expansion gaps around the perimeter of the room. These gaps, typically 1/4 to 3/8 inch (6-10 mm), allow the floor to expand and contract. Use spacers between the planks and the walls.
Install the first row
Begin in a corner, usually the one furthest from the door. Place the first plank with its tongue side facing the wall. If the tongue faces the wall, you’ll need to cut it off using a utility knife or a saw. Place spacers between the plank and the wall on all sides to maintain your expansion gap. Connect the next plank by angling its tongue into the groove of the first plank and pressing down. Continue across the room, connecting planks end-to-end. You may need to cut the last plank to fit, remembering to leave an expansion gap at the end wall.
Install subsequent rows
Start the second row with the offcut from the first row, provided it’s at least 6 inches long, to create a staggered pattern. This staggered pattern adds strength and visual appeal. Angle the long edge of the plank into the groove of the previous row and then lower it to lock. For the short ends, angle the new plank and then use a tapping block and hammer to gently tap the plank into place, ensuring a tight seam. A tapping block protects the edges of the laminate from damage during this process.
Continue laying rows, using the tapping block and pull bar as needed. The pull bar is essential for tightening planks at the end of rows or against walls where the tapping block can’t reach. Always ensure the planks are fully locked together, both along the long edge and the short end. Periodically check your expansion gaps to ensure they are maintained.
Cut around obstacles
Doorways, cabinets, and other fixed objects require careful cutting. For door jambs, you can often slide the laminate under the lip of the jamb to create a clean look. Measure and mark the plank, then use a jigsaw or handsaw to cut out notches or curves as needed. For pipes or columns, measure the diameter and mark the center on the plank. Cut out a circle slightly larger than the pipe’s diameter to allow for expansion. You can then cut the plank from the edge to the center of the hole, install it, and glue the cut edges back together. Cover the gap around the pipe with a rosette or escutcheon.
Install finishing trim
Once the entire floor is laid, remove the spacers. The final step is to cover the expansion gaps with trim. Baseboards or quarter-round molding are typically used. These should be nailed to the wall, not the laminate floor. If your existing baseboards are too short to cover the gap, you can add a quarter-round molding below them. Ensure the trim is securely fastened and provides a clean transition from the laminate to the walls.
Common Mistakes When Laying Laminate Flooring
| Step/Tool | Typical Mistake | How to Avoid It |
|---|---|---|
| Subfloor Preparation | Installing over an uneven or dirty subfloor. | Thoroughly clean and level the subfloor. Use a leveling compound for low spots and sand down high spots. Check for flatness with a straight edge. |
| Acclimation | Not acclimating the planks to the room’s environment. | Store unopened boxes flat in the installation room for 48-72 hours before starting. |
| Expansion Gaps | Forgetting or not maintaining expansion gaps around the perimeter. | Use spacers (1/4″ to 3/8″) between planks and all walls, doorways, and fixed objects. Ensure these gaps remain throughout installation. |
| Tapping Block | Damaging plank edges by tapping directly with a hammer. | Always use a tapping block between the hammer and the plank edge to distribute force and prevent chipping or denting. |
| Staggering Joints | Creating seams that line up in adjacent rows (creating a ‘H’ pattern). | Ensure end joints are staggered by at least 6 inches for structural integrity and a more natural look. |
FAQ
Can I install laminate flooring over existing vinyl flooring?
Yes, in many cases you can install laminate flooring over existing vinyl, as long as the vinyl is a single layer, securely adhered to the subfloor, and not heavily textured or cushioned. You still need to ensure the vinyl surface is clean and level. Check the laminate manufacturer’s guidelines for specific exclusions.
What is the best saw to use for cutting laminate flooring?
A miter saw is ideal for making straight, clean cuts for length and angle. A jigsaw is useful for cutting around curves, door jambs, or irregular shapes. A circular saw can also be used for straight cuts, especially in larger rooms. Always wear safety glasses when operating any saw.
How do I handle transitions to other flooring types?
Transitions are typically handled with specialized transition strips (e.g., T-molding, reducers) that are designed to bridge the height difference between laminate and another flooring type, or to cover the expansion gap at a doorway. These are usually secured to the subfloor or the adjoining flooring, not the laminate itself.
Do I need an underlayment for laminate flooring?
Most laminate flooring requires an underlayment for cushioning, sound reduction, and moisture protection. Some laminate planks come with a pre-attached underlayment. Always check the manufacturer’s recommendations, as they will specify the type of underlayment needed and whether a separate vapor barrier is required.
