If a part of a subfloor has a height difference or is uneven, you will need to level or raise the vinyl plank flooring. What are the steps to do this? How can you elevate the floor properly without mess and damage? Find out what you need to know from this post, as we share information from professional flooring contractors.
Underlayment is the way to raise vinyl plank flooring for floor proportion. Vinyl plank has protective layers, but it's not enough to have that thickness to level your whole flooring. Follow these steps to raise an uneven subfloor for vinyl plank flooring through underlayment:
- Choose the best underlayment that works with your subfloor.
- Remove dust or dirt particles and oil.
- Clean and dry the subfloor completely.
- Place the underlayment in the direction opposite to your flooring.
- Install the underlayment starting from one corner to the opposite side of the room.
- Make a two-inch border on every side to be trimmed out later.
- Place the rest of the underlayment continuously with no overlap.
- Secure the underlayment with special seam tape or good-quality duct tape.
For a concrete subfloor, patching a layer of concrete can even it out if there's a big height difference. You can smooth out the bumpy subfloor by adding a layer of wood, such as particleboard or plywood. For slight differences, an underlayment will do the job.
Underlayment requires knowledge of the best or appropriate materials and tools. Continue reading this post for a guide to working with vinyl plank flooring and underlayment, and making your project flawless.
Raising Vinyl Plank Flooring
Underlayment is not optional in vinyl plank flooring installment. Aside from its other functions, it smooths out subfloor imperfections and roughness. It is installed right before the vinyl plank flooring or the finish layering.
Tools To Use
Preparing the subfloor and rolling out the underlayment will go smoothly if you use the right tools.
- Safety gear: gloves, eye protector
- Cleaning tools: sweeper or vacuum
- Cleaning agents: mineral spirits to remove oil or degreaser; mix one part vinegar with one part water to get rid of the smell and for disinfection
- Cutting tools: razor blade or saw (hard underlayment), utility knife (soft underlayment)
- Sealing tape: sealing tape or duct tape; you may add glue for stability.
1. Choose the best underlayment for your subfloor.
Underlayment is made of different materials. To choose the correct underlayment, know the subfloor type. Adding additional underlying material that works well with the subfloor will instantly solve the issue. It will fill up the space achieving seamless vinyl plank flooring throughout the room.
Here's a list of underlayment materials that match the types of subfloor:
- Concrete subfloor: underlayment made of foam, felt, or cork
- Wood subfloor: underlayment made of felt
- Existing floor/subfloor: hard underlayments such as plywood or cement board

2. Remove dust or dirt particles and oil.
Of course, before putting another layer on your subfloor, you want to make sure that it will seal tightly with the adhesive. A dirty, oily surface makes the underlayment application difficult and allows a lot of liquid entry that can ruin the whole underlayment or even the subfloor.
You can use a degreaser for the cement or tile subfloor. Mix equal parts warm water and vinegar. Dampen a sponge or cloth with the mixture and wipe the area.

3. Clean and dry the subfloor completely.
Use a clean, dry mop to dry the subfloor quickly, or let it dry naturally. Open the windows to ventilate the room without a chance of developing any mold or damp corners. Setting some fans on the wet subfloor can also expedite the drying.
4. Place the underlayment in the direction opposite to your flooring.
Do not install the underlayment in the same direction as your flooring. It should be placed in the opposite direction so that it will create a strong, flat structure. It will also help to have a good seal on the subfloor.
5. Install the underlayment starting from one corner to the opposite side of the room.
Start from the corner, not at the center. It will impede the momentum of having a one-way or straight application. You might end up cutting and fitting the underlayment if that's the case. Work your way out only on the edges but the main floor usually requires a simple application.
6. Make a two-inch border on every side to be trimmed later.
Reserve a two-inch allowance of space on every side. The two-inch border will make sure that the sides have enough border to cover the edges. Putting all to the center may cause uneven layering leaving wide spaces without underlayment on the sides. It is also necessary when you seal the side underlayment.
7. Place the rest of the underlayment continuously with no overlap.
Overlapping can cause warping or buckling. Make sure that the underlayment fits smoothly. Overlapping underlayment again can be annoying and allow dirt and water to get in.
There can be mold and loose vinyl planks if water gets under them. If you let moisture seep into the flooring, it will cause more damage. It can cause premature aging and the deterioration of your vinyl plank flooring.
8. Secure the underlayment with seam tape or good-quality duct tape.
Fastening every line and edge of the underlayment with tape creates a more even surface. It also makes the underlayment strong in structure not much relying on the flat subfloor. You should secure each roll together for a tighter and non-overlapping layer.

There are many factors to consider in installing underlayment for durability and performance. Here are some things you should be aware of when using underlayment for your vinyl plank flooring:
- Use a thin layer of underlayment or, before adding layers, check if it will still be level with other rooms.
- Consider door openings and trim sizes.
- Always check the flooring instructions.
- Use the specific type of underlayment that suits your flooring needs. You may need to check with a flooring professional or ask for assistance.
Does Vinyl Plank Flooring Expand And Contract?
Yes. Vinyl plank flooring is receptive to fluctuating temperatures. The environment easily affects the vinyl. It expands and contracts during hot and cold weather.
Why Is My Vinyl Floor Buckling?
At high temperatures, you can experience a buckling of vinyl floors. With low temperatures, the floor contracts, causing spaces between the floor lines. Buckling can also happen because of moisture build-up, pulling a heavy object, or not leaving an allotted room for expansion.
How Flat Should A Floor Be For Vinyl Planks?
In the installation, the subfloor must be clean, completely dry, and flat. The floor should have a 3/16 in. in 10 ft. radius forbearance.
What Can I Use To Fill Gaps In Vinyl Flooring?
You can use double-sided tape and a small piece of lumber (4x4) to top up the gaps in vinyl flooring. Band the tape in the gaps with the lumber on top. Tap the bond using a rubber mallet to seal the gaps.
