Which is better, cement mortar leveling or self-leveling leveling?

Cement mortar leveling and self-leveling leveling comparison words.

For example:

(1) flatness: self-leveling leveling is more flat;

(2) hardness: self-leveling hardness hard;

(3) cost: self-leveling thickness of 3~5mm thick, cement mortar is at least 2.5cm above. Whether it is the cost of labor or material costs? Self-leveling material is more economical;

(4) paving wood flooring, composite flooring, PVC flooring, then, basically need self-leveling leveling. Cement mortar leveling more than can not meet the paving requirements.

(5) In addition, the original rough ground is relatively rough, like this case self-leveling because the thickness is thin? Will not find level ground; then you need to use cement mortar first leveling, and then according to the paving floor needs to choose the leveling material.
