Concrete Finisher how-to
How to Finish a Concrete Slab
Timing is everything: each step happens at a certain stage of set.
Quick answer
Timing is everything: each step happens at a certain stage of set. In short: check; place; screed, then complete the remaining steps below.
Step by step
Check forms, grade and reinforcement before the concrete arrives.
Place concrete close to its final position and spread it with rakes.
Screed the surface level using the forms as guides.
Bull float immediately to smooth ridges and push down aggregate.
Wait for bleed water to evaporate, then edge and cut joints.
Float and trowel when the surface can support your weight with little marking.
Safety reminders for concrete finishers
