General Tile Discussion

After two days of the self leveler being down, I covered up the floor with paper and finished my drywall. 5 days later, I remove the paper to discover that my self leveler has hairline cracks in it. I mixed it according to the manufacturer and used the manufacturer’s primer. The self leveler is on a 1 1/8th inch sub floor that had tile on it previously for over 15 years without any problems.

think I am safe to tile over this? The new tile are larger. 2’x2’
