Can you make self leveling concrete?
Short answer- add lots of water to cement to make it self leveling. Now you will have a new problem- when that much water evaporates the cement will crack because you left out the sand and gravel filler that would normally go into making concrete. All ‘ concrete ‘ is self – leveling if you are able to vibrate it throughly.

How long does it take for self-leveling concrete to dry?

How do you prepare a floor for self-leveling compound?

Why did my self-leveling concrete crack?
A room that is too hot or too cold may cause the self – leveling compound not to set up properly, and can cause it to crack when it dries. You may also need to wait a day or two prior to the application of the self – leveling compound in order to ensure a climate that is conducive for its use.
Can you pour self-leveling concrete over existing concrete?
