Installing carpet on cement can be a rewarding and cost-effective home improvement project. With careful preparation and the right materials, you can enjoy a warm and comfortable floor for years to come. Whether you are a seasoned do-it-yourselfer or a first-time installer, this guide will provide you with the step-by-step instructions you need to successfully install carpet on cement.
Before you begin, it’s important to assess your cement subfloor and make sure it’s suitable for carpet installation. The subfloor should be level, dry, and free of any cracks or imperfections. If there are any uneven areas, they will need to be leveled with a self-leveling compound. Additionally, any moisture issues in the subfloor must be addressed before installing the carpet, as moisture can cause the carpet to buckle or mold. To prevent moisture problems, a vapor barrier should be installed over the cement subfloor before the carpet is laid.
Once the subfloor is prepared, you can begin installing the carpet. The first step is to lay out the carpet and cut it to fit the room. Be sure to leave a few inches of overlap around the edges of the room, which will be trimmed later. Once the carpet is cut to size, you can apply a thin layer of carpet adhesive to the subfloor. Using a notched trowel, spread the adhesive evenly over the subfloor, being careful not to apply too much. Next, place the carpet on the adhesive and press it down firmly. Use a carpet roller to smooth out the carpet and remove any air bubbles. Finally, trim the excess carpet around the edges of the room using a sharp utility knife.
Preparing the Cement Subfloor
Laying carpet on a cement subfloor requires careful preparation to ensure a smooth, durable, and comfortable surface. Here are the steps involved in properly preparing the cement subfloor for carpet installation:
1. Inspect and Clean the Subfloor
Begin by thoroughly inspecting the cement subfloor for any cracks, holes, or unevenness. Fill any cracks with a cement patching compound and level any uneven areas with a floor leveling compound. Remove all dirt, dust, and debris from the subfloor by sweeping and vacuuming. Any existing carpet adhesive or residue should be removed using a floor scraper or chemical stripper. Ensure the subfloor is completely dry before proceeding.
2. Check Subfloor Moisture
Excessive moisture in the cement subfloor can damage the carpet and padding. Use a moisture meter to measure the moisture content of the subfloor. The ideal moisture level for carpet installation is below 12%. If the moisture content is higher, a vapor barrier or dehumidifier may be necessary to prevent moisture from rising into the carpet.
3. Apply Primer or Sealer
To promote adhesion between the carpet and the subfloor, apply a primer or sealer specifically designed for cement surfaces. This will help prevent the cement from absorbing moisture from the carpet and pad, which can lead to buckling and damage. Allow the primer or sealer to dry completely before proceeding.

Installing the Carpet Pad
Installing the carpet pad is a crucial step that provides cushioning and improves the overall comfort of your carpet. Here’s a detailed guide on how to do it:
Preparing the Surface
Before laying the carpet pad, ensure the cement floor is smooth, clean, and dry. Remove any debris or dust using a vacuum cleaner or broom. If the cement is uneven, use a self-leveling compound to smooth it out.
Choosing the Right Carpet Pad
The type of carpet pad you choose depends on the style and thickness of your carpet. Thicker pads provide more cushioning, but they can also increase the height of your door thresholds. Consider the following table for guidance:
Carpet Thickness | Recommended Pad Thickness |
---|---|
Less than 3/8 inch | 1/8 – 1/4 inch |
3/8 – 1/2 inch | 1/4 – 1/2 inch |
Greater than 1/2 inch | 1/2 – 3/4 inch |
Laying the Carpet Pad
Once you have chosen the carpet pad, unroll it and lay it out over the cement floor. Use a utility knife to trim the edges so they fit snugly against the walls and any obstacles. Secure the carpet pad to the floor using carpet tack strips, spaced approximately 6-8 inches apart.
Tip: For added moisture protection, consider installing a moisture barrier underneath the carpet pad. This will prevent moisture from the cement from damaging the carpet.
Cutting the Carpet
Once you have prepared the cement floor, it’s time to cut the carpet. It’s crucial to measure and cut the carpet accurately to ensure a proper fit. Here are the detailed steps to follow:
1. Measure and Mark the Carpet
Measure the length and width of the room, allowing for extra carpet around the edges.
2. Roll Out and Adjust the Carpet
Roll out the carpet in the room and position it where you want it to be, ensuring it’s centered and even.
3. Trim the Excess Carpet
Using a carpet knife or sharp utility knife, carefully trim the excess carpet around the edges. Here are some tips for trimming the carpet:
Tip | Explanation |
---|---|
Use a straightedge or metal ruler | To guide the knife and ensure straight cuts |
Cut away from yourself | For safety reasons |
Overlap at corners | Allow for a small overlap of carpet at corners |
Trim gradually | Cut small sections at a time to avoid mistakes |
