Concrete subfloors are common in Florida homes, so if you’re considering laminate flooring, you may wonder whether the two work together. The answer is yes. Laminate flooring can usually be installed over concrete when the slab is properly prepared. Moisture, uneven areas, and incorrect underlayment can cause problems, though, so preparation matters.
At Carpet Country, we’ve helped people find and install flooring since 1986. Here’s what you need to know about putting laminate over a concrete slab.
Can laminate flooring be installed directly over concrete?
Yes, laminate flooring can be installed over concrete as long as the slab meets the flooring manufacturer’s requirements.
Most laminate is installed as a floating floor. The planks connect to each other rather than being nailed to the subfloor, making laminate suitable for many concrete slabs.
But you shouldn’t simply lay laminate over concrete. The slab needs to be clean, dry, structurally sound, and sufficiently flat. Moisture protection and the proper underlayment may also be required.
How do you prepare concrete for laminate flooring?
Proper subfloor preparation can make a big difference in how your laminate flooring looks and performs. Before installation, the concrete should be inspected for:
Cracks or damage
High and low spots
Dirt and debris
Excess moisture
Old flooring adhesive or residue
Other surface irregularities
The concrete also needs to meet the laminate manufacturer’s flatness requirements. Significant bumps, dips, or damaged areas may need to be repaired before installation.
Experienced installers understand how laminate floors interact with concrete and can determine what preparation is necessary before the first plank goes down.
Do you need a moisture barrier under laminate flooring on concrete?
A moisture barrier is commonly required when installing laminate over concrete, although requirements vary by product and manufacturer.
Concrete can contain and transmit moisture even when its surface looks dry. If that moisture reaches the laminate, it can potentially lead to swelling, warping, or other damage.
This is especially important in Florida, where high humidity can make moisture management a bigger concern. The concrete may need to be moisture tested before the laminate flooring installation. Depending on the laminate, you may need a separate vapor barrier or an approved underlayment with built-in moisture protection.
What underlayment should you use under laminate flooring on concrete?
The right underlayment depends on the laminate product, concrete slab, and manufacturer’s installation requirements. Some laminate floors come with an attached pad, while other products require separate underlayment.
Underlayment can help:
Reduce sound
Improve comfort underfoot
Support the flooring system
Provide moisture protection when designed for that purpose
More padding isn’t necessarily better. Underlayment that is too thick or incompatible with the laminate can interfere with its locking system.
At Carpet Country, we offer underlayment options and can help you determine which products work with your chosen laminate flooring.
Does concrete need to be level for laminate flooring?
The concrete needs to be sufficiently flat, but it doesn’t necessarily need to be perfectly level from one end of the room to the other.
Laminate planks rely on their locking joints to remain securely connected. Excessive dips or high spots can create movement underfoot and place unnecessary stress on those joints.
Before installation, problem areas may need to be patched, filled, ground down, or leveled. Professional installers can evaluate the slab and recommend the appropriate preparation.
Does laminate flooring need to acclimate before installation?
It depends on the laminate manufacturer. Some products require acclimation, while others may have different installation guidelines.
When acclimation is required, flooring is typically left in the installation area for the manufacturer-specified period so it can adjust to indoor temperature and humidity.
Following these requirements is especially important in Florida’s humid climate. You’ll also want to maintain suitable indoor temperature and humidity conditions after the laminate flooring installation.
What are the benefits of installing laminate over concrete?
Laminate wood flooring can transform a plain concrete slab while providing the warm appearance of hardwood. Today’s products come in realistic wood visuals, textures, colors, and plank sizes for traditional, coastal, rustic, and modern homes.
Other benefits include:
Durable surfaces for busy households
Simple routine cleaning
Numerous wood-inspired styles
Budget-friendly options
Floating installation suitable for many concrete slabs
Added comfort with appropriate underlayment
Laminate can be a practical choice when you want a hardwood-inspired style without installing solid hardwood over concrete.
Should you hire a professional to install laminate over concrete?
Click-lock laminate may look simple to install, but the work underneath is just as important as the planks themselves.
Moisture testing, concrete preparation, expansion gaps, underlayment selection, plank layout, and manufacturer specifications all affect the laminate flooring installation. Some mistakes aren’t immediately noticeable and may cause issues later.
Professional installers know how to evaluate concrete subfloors, prepare them correctly, and install different types of laminate according to manufacturer guidelines. That experience can help protect both the appearance and long-term performance of your new floor.
