Can the cement floor be directly paved with the plastic floor?

It can be paved directly, and the cement floor should be treated properly. The cement floor should be smooth, dry and clean, and the pre paving should reach above C30. The ground flatness should reach the standard by grinding. This is a subtraction method; Self leveling is an addition. However, if the cement floor has sand, cracks, hollowing or very rough surface, it cannot be directly paved. These defects will affect the paving effect of the plastic floor, and subsequent use is very prone to damage, peeling and other problems.
