TL;DR
A steel trowel finish is the dense, smooth, almost burnished concrete surface produced by repeated passes with steel blades, by hand or power trowel, after the bleed water has left. It is the standard for interior slabs, garages, and basements that will take flooring, but it is dangerously slick when wet, so codes and good practice exclude it from exterior walks, patios, and pool decks in favor of broom texture.
What it means
A steel trowel finish is the dense, smooth, almost burnished concrete surface produced by repeated passes with steel blades, by hand or power trowel, after the bleed water has left. It is the standard for interior slabs, garages, and basements that will take flooring, but it is dangerously slick when wet, so codes and good practice exclude it from exterior walks, patios, and pool decks in favor of broom texture. Overworking air-entrained exterior concrete this way also traps water under the surface and invites scaling.
