Self leveling underlayment, also known as self leveling compound or floor leveler, is used to level out shallow dips and humps in a subfloor, prior to installing a finished floor covering. Because self leveling underlayment is very thin, it can be troweled out to make these small adjustments without adding an additional layer of subflooring.
Today we will discuss what self-leveling underlayment is, how it helps flatten a subfloor, and offer a couple of tips from the pros.
What is Self-Leveling Underlayment Made Of?
There are a few different mixtures of self-leveling underlayments available, but generally they all share the same basic idea. Consisting of very thin cement, polymers, and other ingredients, self leveling underlayment is designed to spread out and find its own level, just as any liquid. Special chemical binders also help the material bond to wood, concrete, and many other subfloor materials. Self-leveling underlayment has a very fine texture, and when mixed as directed forms a slurry that can be poured directly onto the subfloor.
Is Self-Leveling Underlayment Hard to Work With?
In most situations, a typical homeowner can successfully work with this material. For those DIYers with experience mixing mortar or concrete, the project will seem familiar. Self leveling underlayment mixes very similarly to portland cement and uses the same tools to apply it. The material can also be used in layers, so if the floor has undulations greater than , more self leveling underlayment can be added.
Todays Homeowner Tips
Be careful when applying self leveling underlayment in many layers, as self leveling underlayment is quite heavy. Adding too much weight to a wood framed floor system can cause floor support problems.
How Do I Use Self-Leveling Underlayment?
In most instances, the self-leveling underlayment will be used in preparation for tile, hardwood, or other finished floor covering. The professionals will often place a long level or straightedge on the subfloor to determine its flatness. If there are humps in the subfloor greater than , many times the best option is to use an appropriate sander to remove them. Next, the level or straightedge is again placed on the subfloor, but this time the target is light appearing under the tool.
Image credit: CanvaLight shining under the straightedge indicates a low spot. The pros will then mark this area with a pencil and apply the underlayment, spreading it out until it can be screeded. Screeding is the process of pulling a straightedge across the surface to remove any underlayment higher than and spread it to any low areas. The main goal is to fill in the dips without adding any more underlayment than necessary. Once it has been screeded, the underlayment can be troweled as needed and allowed to cure.
What Kind of Finished Flooring Can I Use Over Self-Leveling Underlayment?
Generally, any finished flooring material can be applied over self-leveling underlayment. Because the material is applied in a very thin consistency, it can be used under carpet, sheet flooring, vinyl, tile, laminates and most other finished floors. Self leveling underlayment can also be applied under vapor barriers, carpet padding, and laminate foam underlayments as well.
Todays Homeowner Tips
If available, use a corded, ½ drill and mixing paddle to mix in the water. Many cordless drills lack the chuck diameter or torque needed to turn a large paddle and may result in damage to the drill.
How Does Self Leveling Underlayment Work?
The material comes in bags similar to portland cement, mortar, and concrete. When mixed with water, self-leveling underlayment reacts chemically, just as cement would and begins to harden. If mixed to the correct consistency, self leveling underlayment will spread out when poured onto a surface and seek its own level, lessening the labor required for a very thin coat. If the material is mixed too densely, it will not flow easily and will usually require additional troweling.
However, self-leveling underlayment is not just watered down cement. Self leveling underlayment contains additional additives like polymers that allow it to flex slightly without breaking. Additional ingredients are added to improve its bonding to surfaces, and still others to keep the material thin so it will flow. Self leveling underlayment can also improve the bonding characteristics of adhesives, like carpet glue and engineered flooring adhesive.
How Do I Use Self Leveling Underlayment?
Different manufacturers will have slightly different directions, but most will work in a similar way. Before the material can be mixed, the floor should be closely inspected for defects. Although it may seem insignificant, even a small irregularity on a floor surface can be troublesome after the finished floor is installed. The first step should be to scrape the floor to identify any fasteners or adhesives that protrude beyond the surface of the subfloor. After these are found and removed, a straightedge can be laid across the floor in sections to identify any humps or dips.
At this point, using the straight edge mentioned earlier, the next step is to identify the high areas and low areas. After the high spots have been corrected via sanding, the self leveling underlayment is mixed according to the manufacturers directions. With most brands, this slurry is often poured directly onto the subfloor and lightly screeded to help the material flow. After the material begins to solidify, a long trowel is often used in broad, arching movements to ensure the material fills in the low areas. After the material has cured, it can itself be sanded if needed to ensure the surface is flat.
Self Leveling Underlayment Saves Time and Money
How can using self leveling underlayment save money? Self leveling underlayment is not inexpensive, but compared to installing an additional layer of subflooring like 5/32 plywood sheets, it can save both money and time. Self leveling underlayment does not require the fasteners, materials, nor tools that an additional subfloor does, nor the effort to install them. In many situations, this makes self leveling underlayment the most cost effective solution for uneven floors.

What Is Self-Leveling Concrete?
Polymer modifications to concrete create an extremely viscous material called self-leveling concrete. Like a thick liquid, it is poured over the floor and let run into corners and across the room to produce a smooth, uniform surface with little to no work on your part.
Use it to smooth down concrete, tile, or plywood before putting down LVP, tiles, or wood flooring on the inside of your home.
Its true that self-leveling concrete makes construction simpler, but it doesnt imply anything can go wrong. Its not simple to acquire the ideal mixture, pour it in time before it sets, or choose the best possibilities for a certain setting. Many things may go wrong with this kind of do-it-yourself endeavor.
What follows is a comprehensive guide on the usage and application of self-leveling concrete. You may also be interested in reading our evaluations of other self-leveling concretes.
Advantages Of Self-Leveling Concrete
Self-leveling concrete has several benefits beyond merely saving you money compared to hiring a professional to level your floor using regular concrete. To complete the job, your expert builder may even employ self-leveling concrete.
Since water isnt needed to set self-leveling, theres less of a chance that it will get overwatered.
Strong and smooth, self-leveling concrete is a popular construction material. The floor is smooth and sturdy enough to be used on its own, but it also works well as an underlay for other types of flooring.
Not only is self-leveling concrete useful for leveling concrete, but it may also be used to cover other, less forgiving surfaces, such as ceramic tile, luxury vinyl plank (LVP), wood, or plywood.
Even inexperienced users can effectively utilize self-leveling concrete to create perfectly flat floors.
Reinforced concrete is ideally suited to the increased strength that self-leveling concrete provides.
The likelihood of an allergic reaction to self-leveling concrete is quite low. Contrast this with the risk of occupational asthma caused by exposure to chromium in traditional concrete.
Mold development in damp environments is also reduced in self-leveling concrete.
Because of how quickly self-leveling concrete dries, you may move on to the next phase of the project much sooner (with fewer chances for anyone to put a footprint in your work).
Disadvantages Of Self-Leveling Concrete
Self-leveling concrete offers many benefits, but like every product, it also has downsides and things to watch out for.
Work swiftly since self-leveling concrete dries quickly. In some cases, you may only have 20 minutes to mix, pour, and finish a surface before it dries or becomes unusable due to weather or other factors.
The sub-base is not strengthened in any way by the self-leveling concrete that is used for the base. Problems with the subfloor can cause the self-leveling concrete to loosen, which in turn damages any flooring that is placed on top of it.
It can adhere strongly when self-leveling concrete is splattered on tools or other surfaces. All of these things must be cleaned quickly to prevent lasting staining.
Different Types of Self Leveling Concrete
Self-leveling concrete can be either acrylic- or water-based.
Acrylic Self-Leveling Compound
An acrylic self-leveling compound is created by combining a liquid acrylic polymer with cement powder. The finished floor is resilient (for concrete) and can withstand wear and tear without showing signs of wear and tear. The drying time is longer compared to the other self-leveling concrete.
Water-Based Self-Leveling Compound
Self-leveling compounds that employ water as a lubricant provide a surface with characteristics closer to those of regular concrete. As little as 20 minutes is all it takes for it to dry completely. Commonly, this is sold in dry powder form and then reconstituted with water.

Best Self-Leveling Concrete: A Buying Guide
Whether youre looking for a product with high compressive strength or a quick drying period, it can be difficult to sort through the plethora of self-leveling concrete options on the market and choose which one will work best.
Self-leveling concrete is convenient since its easy to select the proper mix. If you only follow this handy buyers guide:
When attempting to correct a lack of flatness, it is usually a good idea to measure the concrete and note both the lowest and maximum thicknesses.
Self-leveling concrete comes in a wide range of thicknesses, from 1/16 inch to 5 inches. However, a thin self-leveler cannot be applied thickly. To get the desired thickness, you must specify the number of layers you are ready to merge.
Flow
If the self-leveling concrete is pouring at a good rate, youll have less trouble getting the job done. The concrete will automatically position itself in the region if the flow rate is increased.
The rate at which the self-leveling concrete repairs itself is likewise dependent on the flow. If you want an even coating of concrete, you wont have to force yourself or work too hard.
Curing Time
How long does it take for self-leveling concrete to dry? This may be the most crucial factor. This is another case where the answer is conditional on the specific self-leveling concrete product in the issue.
You should search for a product that dries in under 90 minutes if you require a fast turnaround.
If youre willing to wait, you may find a product that dries in only two or three days. Your personal tastes should prevail in the end.
Stress in a Compressed State
The self-leveling concretes durability will change depending on its intended use: home, office, supermarket, or industrial warehouse. There is a unique compressive strength associated with each variety of self-leveling concrete.
Some may reach 7,500 psi or even higher. The self-leveling concretes capacity to support weight and traffic will increase as its compressive strength increases.
FAQs about Self-Leveling Concrete
To What Extent Should Self-Leveling Concrete Be Applied?
The self-leveling concrete should be applied at a thickness that is appropriate for the purpose and the particular product being used. The typical range for thickness is between 1/8 and 1 inch. Its possible to have a thickness of as little as 1/25 inch or as much as 6 inches.
How Much Space Can Be Covered by a Single 50-Pound Bag of Self-Leveling Concrete?
One-eighth of an inch of self-leveling concrete should be enough to cover 50 square feet, therefore a regular 50-pound pack should be sufficient.
The Mechanism of Action of This Self-Healing Concrete Needs Clarification
Since self-leveling concrete is so thick and sticky, you wont need a trowel to spread it. Similarly, to a viscous liquid, concrete will flow into empty spots and fill them as you work. The cement will cure quickly and evenly, creating a smooth surface. The structure and the setting are more durable than regular concrete.
Must A Primer Be Applied Before the Leveling Procedure Can Begin?
The surface should be primed before the self-leveling concrete is applied. You may not need to prime the surface if you get a self-leveling concrete product from a company that also sells a primer or one that mixes the two together.
Do You Think the Second Layer of Self-Leveling Concrete Is Required?
There is the option to add a second coat of self-leveling concrete, but only after the first layer has fully cured and set. Before painting the second coat, you can also use a primer.
