2. No measures are taken during the installation of slightly uneven ground

Usually, the ratio of self-leveling cement to water is 1: 2 to ensure that the cement can flow, but it should not be too diluent. Finally, wait for it to dry completely rough 48 hours (depending on the leveled area).

2. Leveling with gypsum or sand
