Self-Leveling Compound If you only have a small amount of old thinset that you need to tile over, use a self-leveling floor compound to smooth out the entire floor. Self-leveling compounds start out liquid but harden to a smooth, flat surface ideal for tiling. This includes any old thinset.

Can you use Portland cement to level floor?

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.

Is floor leveler the same as thinset?

It’s the same way thinset and self-leveling work. Thinset (aka the bed sheet) is difficult to get perfectly level, so you need a very strong flooring type to hide any “imperfections.” Ceramic, glass and stone tile floor coverings work great with latex-modified thinset.

How do you make your own self leveling compound?

A very basic one is 1 cement to 4 fine triple wash sand. Add a small amount of synthetic plastisizer, around 3tsp. Mix with clean water and mix for no more than a couple of minutes.
