2 Concrete Finishing (1) Strikeoff or Screeding - Striking off excess concrete to bring the top surface to proper grade. (2) Bullfloating - Leveling to eliminate high and low spots. (3) Floating - The purpose is to firmly embed the aggregate, to compact the surface and to remove any surface imperfections. To be performed when the concrete is able to sustain foot pressure with only slight indentation. (4) Troweling - Finishing to obtain a smooth, dense surface. (5) Texturing - Finishing to obtain desired surface texture.
