In order to get the best possible results when doing cement work, you should have the right concrete tools. Those who have done concrete work using the wrong tools know how hard it is to do that kind of a cement job.

Before you can pour new concrete, there is often old concrete that needs to come out. Cutting the concrete with a diamond saw blade can be a great way to get a solid and straight line in the existing concrete to butt up to.

After you remove the old concrete, it is time to prepare the ground for the new concrete. If the old concrete sunk and that is why you are replacing it, then you may need to add some base and do some major compacting work to make sure that the new concrete does not have the same problem. Once the ground is prepped, you then will need to place concrete forms. When forming, it is always better to use too many stakes rather than not enough. If you try to skimp by, you may find a form bulging from the weight of the cement during the pour, causing the concrete to not have a straight edge or a weird curve to it. For some concrete pours, you will also need to place rebar in the concrete area to reinforce the cement. When pouring the concrete where the rebar is, you will pour a little over it, then raise it up and let it sit on the bottom of the concrete and then pour over the top of it. The goal is to have it in the middle of the concrete as much as possible.

Before you have the concrete truck come to make the pour, you should be well prepared ahead of time. You will want to consider how large the pour is and if you are going to need some help. Can the cement truck pull up to the area to be poured and dump from the shoot? Will you need to wheel barrow the concrete to the pour site? Is it large enough that you should get a concrete pump? Do you know where all of your concrete tools are at?

Once you have established the answers to these questions and made the necessary arrangements for the help, equipment and tools that you will need, you can schedule the concrete pour. Most people prefer to pour early in the morning so that they have the whole day to work and finish the concrete.

When the truck arrives, the driver will ask you what slump you would like. This essentially means how runny or stiff would you like it. The stiffer it is, the quicker it will set, but the tougher it is to work with. Do not make that decision until the truck arrives because you will want to base that on the weather and the amount of help you have at that moment. If it is hot or if you do not have a lot of people you should make sure that you have a really wet concrete to give yourself more time to finish the concrete.

Once the concrete is down, it needs to be screeded using a concrete screed. Some people use a 2X4 to do this, while others have an actual screed tool. The idea of using a screed is to make the concrete level with the top of the concrete forms. Once this is done the concrete will be worked with a float to bring the moisture, or cream as it is called, to the top to create a smooth surface.

While one person is working the float, another will come behind them and put a rounded edge on the top edges of the concrete using a tool called and edger. Another person comes behind them to smooth the lines with a trowel. This series of steps is repeated several times during the concrete curing time until the concrete is stiff enough to put the finishing touches on it.

One of the more under utilized of all concrete products by those who do not do cement work much is diamond saw blades. However, it is one of the more useful tools in saving time in cement work.
