Get Tru Self-leveling

Self Levelling Flooring compound incorporates specially blended cements, graded sands and organic super-plasticisers, which with the addition of water, give the ideal properties for application to masonry based floor surfaces such as tamped or worn concrete and sand/cement floor screeds.

At a pourable consistency, a 50 lb (22.6 kg) bag will provide 0.45 cu ft (12.7 L) of material. Typical results obtained with QUIKRETE® Self-Leveling Floor Resurfacer, when tested in accordance with ASTM C1708, are shown in Tables 1& 2. Large holes should be repaired. Repair holes deeper than 1 inch (25 mm).

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. ... Short answer- add lots of water to cement to make it self leveling.

Self-leveling concrete is typically used to create a flat and smooth surface with a compressive strength similar to or higher than that of traditional concrete prior to installing interior floor coverings.

At half-inch thickness, a 50-pound bag of Concrete Leveler will sufficiently cover 12 to 15 square feet. For a quarter-inch-thick application, the same size bag would cover between 24 and 30 square feet.

Portland self leveling cement is a type of pourable cement that is primarily used in the preparation of interior floors as an underlayment to support new floor covering installations. ... It's easy to use, and an excellent way to fix cracked, uneven or out-of-level floors with minimal effort.

The plasticizers needed to make concrete self level without adding more water are fairly high tech and proprietary. On commercial jobs We used to throw a couple shovels of bar sand, and cement in with the thinset and use that as self leveling. It would mix to the same consistency, and feel as slc.

bag of standard self-leveling concrete should cover around 50 square feet at inch thickness.

Normal coverage seems to be between 1.5 and 1.7 kg's powder per mm thickness per m2. Some go as low as 1.25kg/mm/m2. The amount you need depends on what SLC you choose, and how thick you want to pour, which in turn depends on how uneven/out of level the surface is, and if you want to build a gradient or not.
