Preparing the Concrete Surface
Before laying vinyl flooring on cement, meticulous preparation of the concrete surface is essential to ensure proper adhesion and longevity of the floor. Begin by thoroughly cleaning the cement to remove dirt, grease, oils, and any residues that could prevent the vinyl from sticking properly. Use a heavy-duty cleaner or degreaser and scrub the surface with a stiff brush, then rinse well and allow it to dry completely.
Next, inspect the concrete for cracks, holes, or uneven areas. Small cracks or holes should be filled with a cement patching compound or a self-leveling concrete patch. For larger imperfections or uneven surfaces, use a self-leveling underlayment to create a smooth, flat base. This step prevents the vinyl from cracking or showing imperfections once installed.
Moisture is another critical factor. Cement slabs can retain moisture, which may cause the vinyl to bubble or peel. Conduct a moisture test, such as the plastic sheet method, to determine if moisture vapor is escaping from the concrete. If excessive moisture is detected, install a moisture barrier or apply a moisture mitigation system designed for concrete floors.
Acclimating and Cutting Vinyl Flooring
Vinyl flooring must be acclimated to the room’s temperature and humidity before installation. This process helps prevent expansion or contraction after installation, which could lead to gaps or buckling. Lay the vinyl planks or sheets flat in the installation area for at least 48 hours.
When cutting vinyl to fit the room, use a sharp utility knife and a straight edge to ensure clean, precise cuts. Measure carefully, especially around doorways, corners, and obstacles. For sheet vinyl, unroll and trim the material to fit the area, leaving a slight gap around the perimeter for expansion.
Applying Adhesive and Laying Vinyl
Choosing the correct adhesive is critical for securing vinyl flooring to cement. Many vinyl products come with recommended adhesives, typically pressure-sensitive or acrylic-based adhesives suitable for concrete.
Apply the adhesive evenly using a notched trowel, following the manufacturer’s instructions regarding open time and working time. Start laying the vinyl from one corner of the room, pressing it firmly into the adhesive. Use a roller to ensure full contact between the vinyl and the cement surface, preventing air pockets and bubbles.
Seaming and Finishing Touches
For vinyl sheet installations, seams need to be carefully joined to prevent water infiltration and maintain a smooth appearance. Use a heat welding tool or seam sealer recommended by the vinyl manufacturer to bond the edges securely.
Trim any excess material around edges and install baseboards or quarter rounds to cover the expansion gaps. This not only provides a polished look but also allows the vinyl flooring to expand and contract naturally without buckling.
Maintenance Tips for Vinyl on Cement
Proper maintenance extends the life of vinyl flooring installed over cement. Follow these guidelines:
- Clean spills promptly to prevent staining.
- Use a damp mop with a vinyl floor cleaner for regular cleaning.
- Avoid abrasive cleaning tools or harsh chemicals.
- Place protective pads under heavy furniture to prevent indentations.
- Maintain indoor humidity levels to minimize vinyl expansion or contraction.

Preparing the Cement Subfloor for Vinyl Flooring
Proper preparation of the cement subfloor is essential to ensure a durable, smooth, and long-lasting vinyl flooring installation. The condition of the cement directly affects adhesion and the overall finish.
Begin by thoroughly cleaning the subfloor to remove all debris, dust, grease, and any loose particles. Use a broom or vacuum to clear dust, followed by a damp mop with a mild detergent solution. Allow the floor to dry completely before proceeding.
Inspect the cement surface for cracks, holes, and uneven areas. Small cracks and holes can be repaired using a cement patching compound or a self-leveling underlayment to create a flat surface. For larger imperfections, professional repair may be necessary.
- Moisture testing: Vinyl flooring requires a dry subfloor to prevent adhesive failure and mold growth. Use a moisture meter or a plastic sheet test (taping a 2×2 foot plastic sheet to the floor for 24 hours) to check for moisture.
- Moisture barrier: If moisture is detected, install a moisture barrier or use a moisture-resistant adhesive specifically designed for vinyl on concrete to mitigate issues.
- Leveling: The cement floor should be level within 3/16 inch over 10 feet. Use a self-leveling compound to smooth out irregularities.
| Step | Action | Tools/Materials Needed |
|---|---|---|
| 1 | Clean subfloor thoroughly | Broom, vacuum, mop, mild detergent |
| 2 | Inspect and repair cracks/holes | Cement patching compound, putty knife |
| 3 | Test for moisture | Moisture meter or plastic sheet |
| 4 | Apply moisture barrier if needed | Moisture barrier membrane or special adhesive |
| 5 | Level subfloor surface | Self-leveling compound, trowel |
Installing the Vinyl Flooring Over Cement
With a clean, level, and dry cement subfloor, you can proceed to install vinyl flooring using either a glue-down method or a floating floor approach. The choice depends on the type of vinyl and the subfloor condition.
Glue-down vinyl flooring: This method uses adhesive applied directly to the cement. It is ideal for sheet vinyl or vinyl tiles that require permanent bonding.
- Adhesive selection: Use a high-quality adhesive formulated for vinyl and concrete. Read manufacturer instructions carefully for application techniques and curing times.
- Application: Spread adhesive evenly using a notched trowel. Work in small sections to prevent drying before vinyl placement.
- Laying vinyl: Carefully place vinyl onto the adhesive, pressing firmly to eliminate air bubbles and ensure full contact.
- Rolling: Use a floor roller to press the vinyl evenly, enhancing adhesion and smoothing out any imperfections.
- Seams and edges: Seal seams with manufacturer-recommended seam sealer to prevent moisture infiltration and improve durability.
Floating vinyl flooring: This method involves vinyl planks or tiles that click together and rest above the subfloor without adhesive.
- Underlayment: Install a moisture-resistant underlayment suitable for cement to provide cushioning and vapor barrier.
- Acclimation: Allow vinyl planks to acclimate in the room for 48 hours to adjust to temperature and humidity.
- Installation: Begin laying planks from the longest wall, clicking pieces together tightly. Maintain a small expansion gap (usually 1/4 inch) around the perimeter.
- Finishing: Install baseboards or quarter-round molding to conceal expansion gaps and complete the look.
