Underlayment serves several essential purposes in a flooring system. It provides a smooth and level surface for the vinyl plank or tile to rest on, ensuring a seamless appearance and preventing any imperfections from showing through. Additionally, underlayment acts as a moisture barrier, protecting the flooring from potential water damage and extending its lifespan. When selecting underlayment for vinyl flooring (sometimes called a vinyl underlay or vinyl floor pad), consider whether you’re installing planks, tiles (including LVT underlayment and underlayment for vinyl tile), or sheet goods.
Another critical function of underlayment is sound insulation. In multi-level homes or buildings, noise reduction can significantly improve the quality of life by minimizing the transmission of sound between floors. The right underlayment can also provide thermal insulation, helping to maintain a comfortable indoor temperature and potentially reducing energy costs. If moisture is a concern, a waterproof underlayment for vinyl flooring can add extra protection. Choosing the correct underlayment can mean the difference between a successful installation and one that faces issues down the line, such as warping or buckling.

Subfloor Condition
The condition of your subfloor plays a significant role in determining the type of underlayment you need. For rough or uneven subfloors, a thicker underlayment may be necessary to provide a smooth surface. This will help prevent any imperfections from showing through the vinyl flooring, which can detract from the overall aesthetic.

Comfort and Cushioning
For areas where comfort underfoot is a priority, such as living rooms or bedrooms, choose an underlayment with good cushioning properties. Foam and cork underlayments often provide the best comfort, making them ideal for spaces where people spend a lot of time standing or walking.
Comfort is not only about the feel underfoot but also about reducing fatigue and stress on the joints. A well-cushioned underlayment can make a significant difference in areas where people stand for extended periods, such as kitchens or workspaces. By prioritizing comfort, you can enhance the overall experience of the space for its users.
The Installation Process
Installing underlayment is a straightforward process, but it’s essential to follow the manufacturer’s instructions for the best results. Here are some general steps to consider, ensuring a smooth and successful installation:
- Prepare the Subfloor: Ensure the subfloor is clean, dry, and free of debris. Repair any damage or uneven areas to create a stable foundation for the underlayment. This step is crucial for preventing issues like bubbling or shifting after installation.

- Secure the Underlayment: Use tape to secure the seams and edges of the underlayment. This will prevent it from shifting during the installation of the vinyl flooring and ensure a snug fit. Properly secured seams also contribute to better moisture and sound insulation. For LVP flooring underlayment, follow any specific seam-taping and moisture-barrier instructions.
- Install the Flooring: Once the underlayment is in place, you can proceed with installing your luxury vinyl flooring according to the manufacturer’s guidelines. Take care to follow any specific instructions regarding the placement and orientation of the planks or tiles.
If you’re still unsure what to put under vinyl flooring or what to put under vinyl plank flooring, consult the product documentation or your installer for guidance tailored to your subfloor and environment.
