Installing Laminate Flooring Over Concrete

Securing laminate flooring to concrete is crucial for a successful and long-lasting installation. Whether you’re renovating your home or upgrading your commercial space, this comprehensive guide will walk you through the process, ensuring a smooth and durable result.

Installing laminate flooring on concrete

The click-lock method, also known as the floating installation method, is one of the most popular and DIY-friendly ways to install laminate flooring, regardless of whether you’re working with concrete or other types of subfloors. This method involves interlocking the planks together without the need for adhesives, creating a “floating” floor that sits on top of the subfloor.

Click-Lock Method

When installing laminate flooring on concrete using the click-lock method, you’ll typically follow these steps:

Prepare the Concrete Subfloor: Ensure that the concrete surface is clean, dry, and level. Any cracks or unevenness should be addressed before proceeding with the installation.

Install a Moisture Barrier: Lay down a moisture barrier or underlayment specifically designed for laminate flooring. This helps prevent moisture from seeping up through the concrete and damaging the laminate.

Start Installing the Planks: Begin in a corner of the room, preferably the longest wall, and work your way across the room. Lay the first row of planks with the tongue side facing the wall, leaving a small expansion gap (usually around 1/4 inch) between the planks and the wall.

Interlock the Planks: As you continue laying rows of planks, use the click-lock system to interlock each plank securely with the previous row. Make sure the planks are snugly joined together without any gaps.

Cutting Planks: You may need to cut planks to fit around obstacles or at the end of rows. Use a saw appropriate for cutting laminate flooring to make precise cuts.

Complete the Installation: Continue installing the planks until you reach the opposite wall. Remember to leave another expansion gap along this wall.

Install Trim: Once all the planks are in place, install baseboards or quarter-round molding to cover the expansion gaps around the perimeter of the room.

You can also install laminate flooring using the tongue and groove method on a concrete subfloor. The tongue and groove method involves each plank having a tongue (a protruding edge) on one side and a groove (a slot) on the opposite side. This allows the planks to fit tightly together, creating a secure and seamless floor.

Tongue And Groove Method

Here’s how you can install laminate flooring with the tongue and groove method on a concrete subfloor:

Tools Required: Laminate Flooring, Moisture Barrier or Underlayment, Tapping Block, Pull Bar, Circular Saw or Jigsaw, Safety Glasses and Ear Protection, Spacers, Utility Knife, Hammer, Pencil and Measuring Tape.

Prepare the Concrete Subfloor: Ensure that the concrete surface is clean, dry, level, and free from any debris. Repair any cracks or imperfections in the concrete before proceeding with the installation.

Interlock the Planks: As you continue laying rows of planks, use the tongue and groove system to fit each plank snugly together with the previous row. Ensure that the tongue of each plank fits securely into the groove of the adjacent plank.

Cutting Planks: You may need to cut planks to fit around obstacles or at the end of rows. Use a saw appropriate for cutting laminate flooring to make precise cuts.

Complete the Installation: Continue installing the planks until you reach the opposite wall. Remember to leave another expansion gap along this wall.
