Can I Lay Laminate Flooring Over Concrete?

Installing laminate flooring over concrete is a common home improvement project that can give your space a new look. But before you start, it's important to understand the essential aspects of this process to ensure a successful outcome.

Moisture Barrier

Concrete is porous, meaning it can absorb moisture from the subfloor. This moisture can cause laminate flooring to buckle, warp, or delaminate. Therefore, installing a moisture barrier is crucial. Plastic sheeting or felt underlayment can effectively block moisture and protect your flooring.

Flat and Level Surface

Concrete subfloors should be flat and level to prevent unevenness in the laminate flooring. Use a level to check the surface and correct any imperfections by grinding high spots or filling low spots with self-leveling concrete.

Expansion Gap

Laminate flooring expands and contracts with changes in temperature and humidity. To prevent buckling, it's essential to leave an expansion gap around the perimeter of the room. Use spacers or a tapping block to maintain a consistent gap between the flooring and walls or other fixed objects.

Underlayment

Underlayment not only provides extra cushioning and insulation but also helps reduce noise and moisture. Choose underlayment specifically designed for laminate flooring and follow the manufacturer's instructions for installation.

Floating Floor System

Laminate flooring is installed using a floating floor system, meaning it is not attached to the subfloor but rests on top of it. This allows for expansion and contraction without causing damage. Click-lock or tongue-and-groove systems enable planks to be joined together easily.

Professional Installation

While installing laminate flooring over concrete is generally considered a DIY project, it's recommended to consult a professional flooring installer if you have any concerns or lack experience. They can ensure proper preparation, installation, and finishing touches for a flawless result.
