Well we ended up pouring our 24'x42' floor slab
last June and it was a lot easier than we thought.
We found that the proper preparation and planning before the pour helped us out tremendously.
We used (1) 12ft Power Screed, (1) 60" adjustable Bullfloat with three sections of handles, (1) power trowel with magnesiusm and steel.
We made a single pour and finished it with a burnt glass finsh. It came out great!
