Installing vinyl plank flooring on a concrete subfloor presents a pressing query: must I apply an underlayment? The resounding response is an unambiguous ‘yes’, particularly for high-end luxury vinyl planks. In reality, an underlayment featuring a built-in moisture barrier assumes paramount importance to guarantee a flawless installation outcome.
Is It Possible to Install Vinyl Plank Flooring on a Concrete Subfloor without Caulking the Planks, and is It Necessary to Use an Underlayment?
Installing vinyl plank flooring on a concrete subfloor can be done, but it’s not always the most recommended approach. Vinyl plank flooring is designed to be installed on top of a plywood subfloor or a concrete subfloor with an underlayment. Without an underlayment, the flooring may not perform as expected.
Vinyl plank flooring is a floating installation, meaning it’s not directly glued to the subfloor. Instead, it’s fastened using a click-lock system or a thin layer of adhesive. However, concrete subfloors can be prone to moisture issues, which can affect the performance and longevity of the flooring.
To install vinyl plank flooring on a concrete subfloor without an underlayment, you’ll need to make sure the subfloor is: * Level and smooth * Clean and free of debris * Dry, with no signs of moisture issues
It’s still recommended to use an underlayment, as it can help to: * Level out minor imperfections in the subfloor * Reduce noise and vibrations * Improve the performance and durability of the flooring
Keep in mind that not all vinyl plank flooring products are suitable for installation on concrete subfloors without an underlayment. Be sure to check the manufacturer’s recommendations before installation.

What Are the Benefits of Using Underlayment with a Layer of Protection for Vinyl Plank Flooring on Concrete?
When it comes to installing vinyl plank flooring on concrete, it’s essential to lay down a layer of underlayment for optimal results. So, what are the benefits of using underlayment with a layer of protection for vinyl plank flooring on concrete?
- Sound Reduction : Concrete is a hard, reflective surface that can amplify every step and sound. Underlayment acts as a sound-absorbing barrier, reducing the noise level and creating a more peaceful living space.
- Moisture Barrier : Concrete is prone to moisture, which can damage vinyl plank flooring. Underlayment provides a breathable barrier that prevents moisture from seeping up and compromising the flooring.
- Thermal Insulation : Underlayment helps to reduce heat conduction from the concrete subfloor, keeping your space warmer in the winter and cooler in the summer.
- Leveling Imperfections : Concrete subfloors often have imperfections, such as dips or bumps. Underlayment helps to level these imperfections, ensuring a smooth, even surface for your vinyl plank flooring.
- Noise and Vibration Isolation : Underlayment helps to isolate noise and vibrations from the concrete subfloor, providing a more comfortable and peaceful environment.
- Improved Flooring Adhesion : Underlayment creates a strong bond between the vinyl plank flooring and the concrete subfloor, ensuring a secure and long-lasting installation.
Can I Install Vinyl Plank Flooring Directly on Slippery Concrete?
Are you looking to install vinyl plank flooring on a slippery concrete subfloor? Before you start, it’s essential to ensure that the surface is suitable for the flooring.
Check the Concrete Subfloor
Before installing the vinyl plank flooring, you’ll need to inspect the concrete subfloor. Look for any cracks, potholes, or uneven surfaces. If you find any issues, you’ll need to address them before proceeding.
- Cracks: Fill any cracks with a concrete patching compound and let it dry.
- Potholes: Fill the potholes with concrete and let it set.
- Uneven surfaces: Check the subfloor levelness with a carpenter’s level. If it’s not level, you can use a self-leveling compound to even it out.
Preparation is Key
Once the subfloor is prepared, you’ll need to clean it thoroughly to ensure a smooth installation. Use a broom or a vacuum cleaner to remove any dirt, dust, or debris.
Vinyl Plank Flooring Installation
To install the vinyl plank flooring directly on the slippery concrete, you’ll need to use a modified thin-set adhesive. This type of adhesive is designed specifically for anchoring flooring to concrete and will provide a strong bond.
- Apply the modified thin-set adhesive to the back of the vinyl plank and press it firmly into place.
- Use a tapping block and a mallet to secure the plank and ensure it’s properly aligned.
- Repeat the process until you’ve covered the entire area.
What Type of Flooring Requires the Most Underlayment on a Concrete Subfloor?
When it comes to installing flooring on a concrete subfloor, one of the most crucial factors to consider is the type of underlayment needed. And, yes, it can get a bit confusing with all the options available!
Floating Floors: The Real Underlayment Champions
If you’re installing a floating floor, such as engineered wood, laminate, or luxury vinyl tile (LVT), you’ll need a significant amount of underlayment to ensure a smooth and even installation.
- Engineered wood flooring requires a minimum of 1/4 inch of underlayment to fill in the gaps and imperfections on the concrete subfloor.
- Laminate flooring typically needs 1/8 inch of underlayment to provide a buffer between the laminate and the concrete.
- LVT flooring can get away with a slightly thinner underlayment of 1/16 inch, but it’s still essential to ensure a level and even surface.
Why So Much Underlayment?
You might be wondering why floating floors require so much underlayment. The answer lies in the nature of concrete subfloors. Concrete can be unpredictable, with fluctuations in temperature and humidity causing it to expand and contract. Without a sufficient underlayment, any inconsistencies in the concrete could be transferred to the flooring, resulting in uneven installation and potentially costly repairs.
Choose the Right Underlayment for Your Flooring Needs
When selecting an underlayment for your floating floor, make sure to choose one that’s compatible with your flooring material and suitable for your climate. Look for underlayments with high compressive strength, moisture resistance, and sound-absorbing properties to ensure a smooth and quiet installation.
How Do I Know If My Concrete Subfloor is Suitable for Vinyl Plank Flooring without Underlayment?
Before installing vinyl plank flooring without underlayment, it’s crucial to inspect your concrete subfloor. A suitable subfloor ensures a smooth, quiet, and damage-free installation. Here’s a step-by-step guide to check your subfloor:
1. Visual Inspection
Look for any visible cracks, potholes, or unevenness in the concrete. If you notice any significant issues, it’s best to address them before proceeding.
2. Check for Moisture
Moisture can compromise the adhesive and cause bubbling or delamination over time. To inspect for moisture:
- Place a small drop of water on the concrete. If it spreads quickly or disappears slowly, the subfloor is likely too moist.
- Use a moisture meter (optional) to measure the moisture levels.
3. Inspect for Adequate Thickness
Vinyl plank flooring requires a minimum of 1/8 inch thick concrete to ensure stability. Use a tape measure to check the thickness.
4. Check for Proper Preparation
Ensure the subfloor is clean, dry, and free of any contaminants. Sweep and mop the area to remove dirt and debris.
5. Check for Levelness
Ensure the subfloor is level and even. Use a level tool to check for any deviations.
6. Check for Adhesiveness
Perform a small adhesion test by applying a small amount of adhesive to the concrete. Wait for 10-15 minutes and gently scrape with a putty knife. If the adhesive lifts easily, the concrete is suitable.
7. Consider Professional Help
If you’re unsure about any aspect of the inspection, consider hiring a professional to assess your subfloor.
If your subfloor passes these checks, it’s likely suitable for vinyl plank flooring without underlayment. Begin your installation by applying a bonding agent and following the manufacturer’s instructions.
