Excellent Product - Water Content is Critical
This is a great product for small jobs around the home, but there are a couple of critical items you must be aware of. First off, if you can actually “pour” the concrete, you have added too much water, and the concrete has lost most if not all of its strength.

The second item I have found is that most people do not mix the product long enough. If you mix it just long enough to blend the ingredients, then place the concrete, it will harden up on you fast. By mixing an additional 3-4 minutes, the product will be more creamy (for lack of better words), and after you place it, you will have the proper time needed to screed it, the cream will rise to the top and finishing will be a breeze.
Most DIYer's seems to want to hurry like a mad man when dealing with concrete, when it should be the opposite. Each step in the process should be done in a timely manner, but never rushed. The whole process takes hours from mixing it to the final finish phase, so take a deep breath and don’t rush it.
This is a great product for the DIYer as long as you are consistent with the water content from batch to batch. Plus, make sure that you mix it long enough. Doing both of these things will not only ensure you do a good job, but an excellent one as well.
