First, clean the area by sweeping or vacuuming it. Next, dampen the area by using a wet sponge to help prevent the material from drying too quickly. Then, pour the self-leveler into the low points. You'll need to use a metal trowel to make sure that the hole is filled before gravity levels it out.
You can install vinyl on many types of subfloor, including concrete and wood. But that floor must be flat for your installation to be a success. An uneven subfloor can lead to potential problems, such as planks having varying heights that will make the flooring unstable and wear down more quickly.
No. Rigid vinyl planks like Sound-Tec, Studio 12, and Foundations float over minor subfloor imperfections. They mask slight subfloor unevenness. However, because of the precisely milled clip system, a flat substrate is recommended for support.
Pour the liquid-like floor leveler onto the subfloor and smooth it out with a trowel. Gravity will help it settle into the low areas. Remove any excess floor leveler and feather it around the edges so it blends with the rest of the floor. Let the floor leveler dry overnight or as indicated by the manufacturer.
Depending on the situation, you can either sand down areas of the subfloor that are too high, or install shims beneath the subfloor so that the entire floor is brought up to the same level.
Self-leveling compound, for example, is an easy way to level and flatten out a vinyl floor before laying laminate planks over the top. Keep in mind, though, that installing new flooring over the old means that you are increasing the overall height of the floor.
Self-leveling compound products can be used on concrete floors, wood subfloors that are uneven but still in decent shape, and even over ceramic tile floors—eliminating the task of tearing out the old tiles. Check to ensure that the product you purchase is compatible with your floor.
Underlayment can help smooth things out, though, but the type you choose will vary depending on your specific reasoning for wanting an even subfloor. That can make choosing the right one for you rather tricky, so here's a quick guide that should lend a helping hand in getting the best underlayment for uneven subfloors.
Most manufacturers recommend that the floor be flat to within 3/16” in a 10 ft. radius. These measurements are consistent with most other types of floor coverings. On floating floors, vertical movement needs to be kept to a minimum.
The best option might be a thin layer of self-leveling concrete followed by a vapor barrier and foam or cork underlayment. Vinyl: Choose foam for low cost; consider cork for a softer floor.
The main cause of warping in vinyl flooring is exposure to direct sunlight during installation, which causes the planks to expand. In the case of glue-down tiles and planks, warping can occur due to water spillage that is not cleaned up immediately and has seeped under the flooring through the seams.
If the proper expansion gap is not left during installation, and the planks on the sides push up against the wall, the pressure will cause planks elsewhere in the room to buckle. Buckling floors are repairable, however, they are a major inconvenience and can be tricky.
Engineered wood flooring is a more traditional option that can be installed over uneven surfaces. It's made of a thin layer of solid wood on top of multiple layers of plywood. Engineered wood flooring is also relatively durable, easy to maintain, and can help retain the look and feel of an historic home.

In some cases, a slight slope may be normal and not cause for concern. However, if the slope is severe or getting worse over time, it could be a sign of a serious problem that requires immediate attention. One potential risk of sloping floors is damage to the structural integrity of the home.
Best Self-Leveling Concrete for a Flat Surface—HENRY 565 FloorPro. The HENRY FloorPro is a great floor leveler that can get a flat and smooth surface. This is due to how easy it is to use this self-leveling compound.
There are self-leveling coatings designed to fill gaps and cracks. You could also try using vinyl floor tiles to make the transition more gradual. Probably the easiest (and cheapest) thing to do would be to get a big diamond grinding wheel and bevel down the lip.
There are two main types of self-leveling underlayment: cementitious underlayment and gypsum underlayment.
How long a floor will take to screed will depend on its size and condition but an average size room should certainly not take more than a day.
Fibreboard Underlay
This is the best choice for both types of flooring. It works to smooth uneven floors, reduces noise, and acts as a thermal barrier. If the subfloor is uneven, fibreboard works to even dips and dents you can't level out.
Forgetting to level the subfloor
The subfloor must be level before installing laminate flooring. If the subfloor is leveled, the laminate planks will not lay properly, causing uneven and unsightly floors. If the subfloor is not level, you can use a self-leveling compound to level it out.
