self-leveling concrete method for undersized and extensive areas

One of the common questions I get is can you self-level the small and large areas in the same manner? Yes with a little variation. And also man work is totally different when you are doing the large, and the speed required and the machines also.

Self-leveling concrete for Small Areas

One of the most important things to do, whether you are self-leveling a small area or a large area, is to take the measurement of the area and know the depth and the distances to cover, so that you will know the amount of bags that will be required for the job. 

How  to calculate the bags required  for the self-leveling 

First, get the total distance of the area to the level: Length X width

Secondly, check the leveler bag pack and see the recommended distance for each bag. Mostly, a bag of a self-leveling compound will cover 20-24 square feet, and this can vary depending on the depth of the floor. 

How many bags does it take to level a small area

Small areas can be equaled to distances of 100 square ft or less, one bag of a self-leveling compound can cover 20 square feet

Can I do self-leveling concrete in sections?

Yes it is possible but there is equipment that you will need so that you will be able to identify the high and lower area because that is the most problem that occurs when doing a self-leveling in sections

Can you add multiple layers of self-leveling concrete?

It is possible to employ many layers on top of one another. Before applying a second coat, just make sure the previous one is completely dried and rigid. Use a primer as you would on any other concrete floor as well.

Self-leveling large area

When self-leveling an area that is 200 square feet or more, it is considered a large area, and the methodology is different and requires the things that we are going to be discussing. In most cases, this is a self-leveling concrete outdoor project.

Spreading self-leveling compound over a large area

There are basically two ways you can achieve this:

The first method requires multiple workers who can do the job (spreading) at the same moment the compound is poured. It is usually the same tools that are required, but what increases is the labor force. 

Secondly, you can do it in sections, This will require a 4D laser leveler, and concrete leveling tripod, that will be used to identify high and low areas, which is very important, considering that this is the biggest challenge that we see when doing self-leveling concrete in sections.     

Priming before self-leveling

How thick can you pour a self leveler?

This totally depends on how large the area is and what you want to use the floor for. If the area that you want to self-level has deep lows or high highs, you may what to make the comp

The difficulties in self-leveling a large area

• The majority of self-leveling underlayments, particularly those most often seen in large box home improvement shops, are designed to dry rapidly. This is by far the most challenging obstacle to overcome.
• Once the pour has begun, larger regions make it harder to reach the center or wall-bound parts of the pour.
• The majority of self-levelers only operate in part-self-leveling mode. Larger regions, which often have greater surface height changes, are where this issue is most evident. Avoid pouring more than is absolutely required since self-leveler is pricey.

Things to do first before you begin to self-level

Buy a self-leveler concrete with a long set time: This is very important to note because it is likely that what you will see in the rapid setting has about 5min of free flow, which is not good for large areas, it is recommended to get a self-leveling concrete that has a 15 minutes free flow before setting

Seek help with the job.  For individuals who have never done this project before, we advise using 5 people for 132 square feet. It can be done with three, but not fewer, with considerable skill. We advise dividing the task into many parts over a few days for really large areas.

Make a detailed plan for the pour and prepare all the materials. The key to a successful pour over a large area is to plan as much as possible before you start mixing the leveler.  Once mixing is underway, you have a finite amount of time to finish before part of the floor starts to dry.

Tools to use when self-leveling Large Area

how to allocate workers for the self-level 

This is crucial in order to create a consistent level and prevent high and low regions when the job is finished. To have the concrete poured, it is important to make sure everyone is cooperating. One spreader, two mixers, and two people who have dual roles of pouring dry powder into buckets and pouring mixed compound for the spreader onto the floor are typical.

How thick should the leveler be poured?

Depending on the product you are using, you can pour self-leveling concrete up to a certain thickness. The standard thicknesses, however, vary from 1/8 to 1 inch. However, there are alternatives for pouring that range from 1/25 inch to 5 inches thick.

Watch out for these issues with self-leveling concrete

A self-leveling compound could dry up very soon. In approximately 20 minutes, you can mix, pour, and level the self-leveling compound. To correctly mix, pour, and distribute the self-leveling compound, one must have all the required equipment and materials.

You will need a gauge rake since the self-leveling compound sometimes does not level properly. After the compound has been mixed with water and poured into the desired location, it is distributed evenly using a gauge rake.
