by James Antony | Last Updated: 23rd March 2021

Best Self-leveling concrete is considered the best choice if you are looking to renovate your floors, but are worried about the condition of the underlying floor. Additionally, you also need to think about the cost it will incur. A professional home decorator will know how to level their own floors with the help of self-leveling concrete.

What is self-leveling concrete? It is a highly vicious concrete and a modified version of a polymer. All you need to do is pour it on the floor and it will cover the surface like a thick liquid. This way, you will be able to create an even and flat surface, without having to waste a lot of effort or time.

This concrete is considered the best option if you are looking to flatten existing hard floors like plywood, tile, or concrete before you decide to install new interior flooring like wood, tiles, or LVP in your homes.

However, just because Self-leveling concrete is easier to apply does not mean you cannot go wrong. For instance, mixing concrete is not easy. You need to understand the thickness of different environments. There are a lot of things that can go wrong with self-leveling concrete.

What are the advantages of using self-leveling concrete?

You will find a lot of benefits of using self-leveling concrete, rather than using traditional concrete or calling in a professional for the job. Apart from saving money, other benefits of self-leveling concrete include:


What are some downsides of self-leveling concrete?

Like the two sides of a coin, self-leveling concrete also has certain disadvantages like:
Since self-leveling concrete dries up fast, you need to work very fast. If the concrete product dries up within 20-minutes, it only means you have roughly 15-minutes to get your work done.

Since self-leveling concrete does not reinforce the under layer on which it is applied, anything that goes wrong with the sub-floor will loosen the self-healing concrete. This will also result in damages to the flooring and sub-flooring.

Because self-leveling concrete dries up fast, it will stick firmly on any surface it gets splashed against. If you do not want the stain to remain permanently, you need to clear it immediately.


Best Self Leveling Concrete – Buyer’s Guide

With the increasing number of self-leveling concrete products available in the market, it may get complicated to choose one that best suits the type, whether you are choosing one with compressive strength or the one with a fast drying time. Thankfully, choosing the right self-leveling concrete is fairly simple. All you need to do is follow this buyer’s guide below:

ThicknessWhen you want to fix the flatness problem, you always need to check for the minimum and maximum thickness of the self-leveling concrete. You will find self-leveling concrete products of varying thickness, ranging from 1/16-inches to five inches. However, if you are looking for a thin self-leveler, it cannot be applied thick. You need to ask how many layers you are willing to combine for the thickness you are looking for.

Flow

If the flow of the self-leveling concrete is high, you will be able to work on your job much easier. With a higher flow rate, the concrete will place itself in the area. Additionally, the flow will also determine how fast the self-leveling concrete heals. You will not have to exert and overwork with the concrete if you are looking for an even layer.

Drying time

This is, perhaps, the most important criteria – how long will it take for the self-leveling concrete to dry up? Again, the answer to this question depends on which self-leveling concrete product you choose. If you want a quick turn-around, you need to look for something that dries out quickly; some products dry out within 90-minutes. However, if you are patient, you can choose a product that dries out within 2-3 days as well. In the end, it is all about your preferences.

Compressive strength

The strength of the self-leveling concrete will depend on what type of floor you are applying on – house, office, grocery shop, or a warehouse. Each self-leveling concrete product has a specific compressive strength.

In fact, some may go as high as 7,500 psi. With higher compressive strength, the self-leveling concrete will be able to handle more load and traffic.

What are the different types of self-leveling concrete?

Primarily, there are two types of self-leveling concrete you will find in the market:

Water-based self-leveling concrete

As the name suggests, this self-healing concrete is water-based. This means that the surface has more consistency than normal concrete. Additionally, it also dries up in as little as 20-minutes. All you need to do is purchase the powder and mix it in water to create the self-leveling concrete.

Acrylic-based self-leveling concrete

This self-leveling concrete compound is made from mixing cement powder and acrylic liquid polymer. This makes the resultant concrete more elastic than normal concrete and more resistant to abrasions and scratches. However, this compound takes more time to dry completely.


Best Self Leveling Concrete – FAQ

Here are some common questions related to self-leveling concrete products:

What is the recommended thickness level of self-leveling concrete?

The thickness of the self-leveling concrete will depend on what type of product you are using and the corresponding job. In most cases, the thickness can be anywhere between 1/8-inches and 1-inch. However, the thickness can be as thin as 1/25-inches or thick as 6-inches.

How much area coverage a standard 50-lbs self-leveling concrete bag provide?

A standard 50-lbs pack of self-leveling concrete should easily cover an area of 50-sqft, with a thickness of 1/8-inches.

How does this self-healing concrete work?

Self-leveling concrete is very viscous; hence, a trowel will not be needed. All you need to do is fill in the spaces and the concrete will move along and fill up the gaps, similar to any viscous liquid. This will create a smooth surface and the cement will dry up fast. The setting is also stronger than standard concrete.

Do you need to use a primer before you proceed with the leveling process?

It is recommended that you prime the surface before applying the self-leveling concrete. Some brands offer a primer with their self-leveling concrete products, while others have already mixed the two so that you do not have to prime the surface separately.

Is it necessary to apply a second coating of self-leveling concrete?

Yes, you have the choice of applying a second layer of self-leveling concrete, only after the first layer has completely dried out and set. You can also apply some primer before applying the second layer.

Final Thoughts

This concrete is considered quite a handy tool when it comes to evening out internal floorings or new flooring. These products are very easy to apply and can be done even by DIY-ers and amateurs, thereby saving you a substantial amount of money. When you are looking for the right self-leveling concrete, you need to know the viscosity that you are looking for so that you end up with a smooth floor surface.
