Installing Carpet on a Concrete Floor: A Step-by-Step Guide

Quck answer

To install carpet on a concrete floor, follow these steps:

1. Prepare the concrete: Clean the floor thoroughly and repair any cracks or uneven areas. Ensure it is completely dry before proceeding.

2. Install a moisture barrier: Lay down a moisture barrier, such as a plastic sheet or vapor barrier, to prevent moisture from seeping into the carpet.

3. Lay carpet padding: Roll out the carpet padding and secure it to the concrete floor using carpet tape or adhesive.

4. Measure and cut the carpet: Measure the room accurately and cut the carpet to fit, leaving a few inches of excess on each side.

5. Install the carpet: Starting from one corner, lay the carpet onto the padding, ensuring it is straight and smooth. Use a carpet kicker or power stretcher to stretch the carpet tightly.

6. Trim and finish: Trim any excess carpet using a utility knife and tuck the edges under baseboards or door thresholds. Use a carpet seam roller to ensure the seams are flat and secure.

By following these steps, you can successfully install carpet on a concrete floor.


Carpet is a popular choice for its luxurious feel underfoot, and it can be a cost-effective option for homeowners on a budget. With the right tools and materials, you can even install carpet yourself on a solid concrete subfloor. Here is a step-by-step guide to help you through the process.

Step 1: Measure the Room

Start by measuring the room to determine the amount of carpet you will need. Measure the length and width of the room, and then multiply these numbers to get the square footage. While carpet is typically sold in yards, you can provide the store or distributor with the square footage for accurate pricing.

Step 2: Prepare the Subfloor

Before installing the carpet, make sure to patch any imperfections in the concrete subfloor. While carpet can hide some flaws, it’s best to address any sagging or bumpy areas. Use a hammer and chisel to chip away any bumps, and fill in low spots with a self-leveling compound. This will create a smooth and even surface for the carpet.

Step 3: Install Tackless Strips

Next, place tackless strips around the perimeter of the room. These strips should be installed 1/2″ from the wall, with the tacks facing the wall. Use masonry screws to secure the strips to the concrete every 6-8″ on center. Cut the strips with tin snips as needed.

Step 4: Secure the Carpet Padding

Apply a small amount of underlayment adhesive around the perimeter of the room to hold the carpet padding in place. The padding should cover the entire floor without overlapping. Use duct tape to tape the seams of the padding together, but avoid adding adhesive near the edges of the room.

Step 5: Cut and Fit the Carpet

Now it’s time to lay out the carpet and cut it to fit the room. Cut strips of carpet that are a few inches longer than the length of the room. Use a utility knife to cut from the back of the carpet, ensuring a straight and even line. If needed, use a straight edge as a guide.

Step 6: Connect the Carpet Sections

Place the carpet into the room, aligning the seams and ends. Place adhesive-side-up seam tape under the carpet to connect the different sections. Use a seam iron to heat the tape and join the sections together securely.

Step 7: Stretch and Attach the Carpet

Stretch the carpet as far as possible with your hands, and then use a knee kicker to pull the corners into place. Start at one corner, hooking the knee kicker into the carpet and tapping it with your knee while pulling the carpet. Repeat this process for all four corners until the carpet is attached to the tackless strips.

Step 8: Finish and Trim

Cut away any excess carpet around the perimeter of the room, or tuck it behind the tackless strips. Install baseboards or trim to cover the gap along the edge of the room, giving your carpet installation a polished look.
