Laminate flooring has become a popular choice for many homeowners due to its appealing look, durability, and affordability. It’s also relatively easy to install a laminate floor on a concrete base, which makes it perfect for DIY projects. One of the trickier surfaces to install laminate on is concrete, mainly because of moisture concerns.
If you’re ready to take on this project yourself, here’s a simple guide to help you install a laminate floor on concrete the right way.
What You’ll Need Before You Start
Before diving in, make sure you have everything you need. The process is straightforward, but having the right materials and tools will save you time and frustration.
Materials and Tools Checklist:
- Laminate Floorboards: Buy 10% more than your room size to account for cuts and waste.
- Underlayment: Helps with moisture control and levels out any small imperfections in the concrete.
- Moisture Barrier: A 6mm plastic vapor barrier to protect your laminate from moisture.
- Tools: You’ll need a saw, rubber mallet, measuring tape, markers, and spacers.
- Adhesive or Nails: Depending on the type of laminate you’re installing, you may need one of these.
Step 1: Prepare the Concrete Subfloor
Concrete floors can have issues with moisture, so you’ll need to make sure they’re dry and level before you install your laminate flooring.
- Check the Concrete’s Condition: If the concrete is new, let it cure for at least 30 days. Inspect it for cracks, uneven areas, or mold. Any cracks or bumps larger than 3/16th of an inch over 10 feet should be leveled out using a concrete grinder.
- Clean the Surface: Make sure the concrete is completely clean. Sweep or vacuum any debris, dust, or dirt. A clean surface ensures a smooth installation.
- Test for Moisture: Moisture is the enemy of laminate flooring. You can test for moisture using a moisture meter. If the reading is above 4.5%, you’ll need to address the issue before continuing.
Step 2: Install a Moisture Barrier and Underlayment
Because concrete tends to hold moisture, it’s crucial to install a moisture barrier. This will protect your laminate from warping or damage over time.
- Lay the Moisture Barrier: Use a plastic vapor barrier (6mm thick) to cover the concrete floor. Overlap the seams by a few inches and secure them with vinyl tape.
- Add the Underlayment: Depending on the manufacturer’s recommendations, you may need a foam, cork, or vinyl-backed underlayment. This layer helps reduce noise and adds a bit of comfort underfoot.
Here is a little more information about the various types of underlayment. The type you choose will depend on either the method of installation or the type of floor you have underneath. Get advice from your hardware store on the best fit for concrete.
- Foam Barrier: This is the most common underlayment as it can be a good option for moisture, absorbs any noise and seals the flooring.
- Cork: While cork is expensive, it is a great option for reducing the noise and cracking sounds when you walk on the flooring.
- Vinyl Backed: Vinyl-backed underlayment is recommended not only to reduce noise but are also suitable for moisture control.
Step 3: Start Laying the Laminate Floor
With the subfloor ready, you can now start installing your laminate planks.
- Acclimate the Flooring: Let the laminate boards sit in the room for 48 hours before installing. This allows them to adjust to the room’s temperature and humidity.
- Lay the First Row: Start in the corner of the room, leaving a ¼-inch gap between the laminate and the wall to allow for expansion. Use spacers to keep the gap consistent. Begin laying the planks side by side, clicking them together as you go.
- Cut the End Pieces: When you reach the end of a row, measure the remaining space and cut a plank to fit. Use a saw for clean, precise cuts.
- Stagger the Seams: For a more natural look and added stability, stagger the seams of each row by cutting the first plank of each new row to a different length.
- Finish with Trim: Once all the planks are laid, install baseboards or trim to cover the expansion gaps along the walls.
Step 4: Caring for Your Laminate Flooring
Laminate is durable, but it still requires some maintenance to keep it looking its best.
- Avoid Water: Since moisture is the biggest threat, never let liquids sit on the floor. Avoid installing laminate in areas with high moisture, like bathrooms or laundry rooms.
- Cleaning Tips: Use a slightly damp mop or a microfiber cloth to clean the floors. Never wax or polish your laminate flooring, as this can damage the finish.
Conclusion
Installing a laminate floor on concrete is a project most homeowners can tackle on their own with the right preparation. By following these steps, you’ll not only ensure a flawless installation but also enjoy your new flooring for years to come.
