Will new cement stick to old cement?
The cement within a concrete mix doesn’t contain any natural bonding agents – so when fresh concrete is added on top of an existing layer of concrete, the two won’t join together. Once cured, the new concrete will simply sit on top as a separate layer. This will not produce a strong, serviceable floor.
