Why Polishing Suspended Concrete Slabs is More Likely to Disappoint Customers

American Society of Concrete Contractors (ASCC)

Polished-concrete specifications are based on experience with slabs-on-grade, so contractors must help project owners understand how results will likely vary when polishing suspended slabs
