Concrete is a very versatile material that can be used in a wide variety of applications where you need a strong, durable surface. Concrete is not just limited to pouring slabs and pouring driveways. You can also use concrete to create walls and other structures which offer the strength and durability of masonry but are much more cost effective.
Concrete finishers are people who have the knowledge to take care of all your concrete needs. They know what tools to use and how to apply the tools in order to achieve the desired results every time. You want your concrete driveway or slab to be strong and durable, but you also need it to look good. A concrete finisher will be able to make sure that your finished project does both.
One thing that professional concrete finishers understand is when is the right time for finishing their work. They know the ideal conditions for working with concrete in order to ensure that it sets properly and hardens as it should. When you try to finish concrete before it has properly set up, you run the risk of causing damage and ruining the surface of your project.
I’ve been an architect for almost 20 years. My work is to create designs, but not to physically construct them. It’s always amazed me how people in construction know how to build things. One of the most fascinating trades of all is the concrete finisher.
In order to create a structure that will last, the concrete must be placed properly, finished correctly and cured carefully. That’s where concrete finishers come in. They have tools that allow them to place concrete properly, finish it according to specs and cure it quickly so that it doesn’t crack or shrink.
Without finishing concrete properly, you’re going to have a mess on your hands. It’s essential that you contact a professional who can help you out with this process. The right finishing equipment makes all the difference in the world. You’ll know when your concrete has been finished properly because it will be flat and level without any pits or divots from poor finishing.
The next step is curing the concrete so that it won’t crack after you’ve already laid it down. Concrete curing blankets are designed for exactly this purpose: to make sure your concrete cures correctly so that you don’t have any cracks or other imperfections once it’s too late for repairs. These curing blankets are made out of plastic
A concrete finisher is a skilled tradesperson who works with concrete by placing, finishing, protecting and repairing concrete in engineering and construction projects. Concrete finishers are often responsible for setting the concrete forms, ensuring they have the correct depth and pitch. Concrete Paving slabs must be even, and achieve the required roughness specifications. Concrete must be smooth and flat when it comes to industrial floors, or there may be a trip hazard.
There are many tools that concrete finishers use to do their job. The most common tool used is a trowel (which is what we sometimes call them). Trowels come in different shapes and sizes for different jobs. There are many other tools of the trade as well though such as screeds, tampers, floats, edgers, groovers, power trowels, scarifiers etc.
A good resource for information on these tools is the website of the International Concrete Repair Institute (ICRI). They have some excellent guidelines you can access here: http://www.icri.org/guidelines/guide_conc_fini.html
Concrete finishing is the process of working the surface of the concrete to achieve a desired effect. When concrete is in its plastic state, it can be molded and manipulated to almost any shape or finish. It can then be smoothed and polished with trowels and other hand tools. The finishing process can also be used to manipulate the overall appearance of the slab so that it looks like stone, brick, or tile.
Concrete Finishing Basics
When you start a concrete project, you should have a clear idea of what effect you are trying to achieve. This will determine which finishing techniques are most appropriate for your application. You may need a professional finisher to help you with this part of the process.
The first step in concrete finishing is called “floating.” The finisher uses a trowel to move the wet concrete around until it fills the form completely and eliminates any air bubbles that may have become trapped during pouring. The concrete must be completely level, so at this point, the finisher may use a screed board. This is a long straight board that is pulled over the surface at an angle to smooth out high spots. A vibrator may also be used during this process to eliminate air pockets and distribute aggregate evenly throughout the slab.
1. Use the Right Slump
The slump test is recommended to be done before each load of concrete is placed. The slump should be between 3 and 4 inches for driveways, sidewalks, and patios. For foundations, the slump should be between 4 and 6 inches. If you are using a ready-mix truck, make sure they add water at the plant as it is difficult to add water once the concrete is placed. A good concrete finisher can visually inspect the concrete and tell you if the slump is in range.
Your project is not complete until your concrete is finished. Finishing concrete is a process that always involves the use of tools.
The right tools will not only produce a more attractive finish, but they will also help you work faster and safer.
Your concrete finishing project will go much faster if you have the right tools at hand before you start. Improve your productivity, safety and efficiency with these tips for choosing the right concrete finishing tools for each job.
If your concrete finishing project requires grinding, polishing or edging, we have all the necessary equipment to get the job done, including handheld and walk-behind grinders and polishers and a variety of edgers from which to choose. From small jobsite grinders and polishers to large grinders for commercial jobs, we carry it all.
If you need to level uneven floors or smooth rough areas, check out our selection of handheld and walk-behind screeds. If you are placing a high volume of concrete such as in a commercial application, consider using a power trowel to make the job easier.
For smaller applications such as basement floors and sidewalks, consider an asphalt cutter or circular saw with diamond blades designed for cutting concrete.

The concrete must not be too wet, but wet enough to work with easily. The finisher will also have to keep the concrete sufficiently wet between the time of finishing and the application of the curing compound.
The finished surface must be as flat as possible so that it can be easily painted. Another requirement is that the edges of the concrete slab must be straight in order for the slab to take a smooth final finish.
When using metal forms, the finisher can use his trowel to form a slight crown in the center of the slab and make sure that both sides slope toward that center. This shape is important because it allows good drainage away from any structures built on top of the slab.
This crowning may also be accomplished by building up a thin layer of soil in the center of a slab cast on subgrade. The final finishing operation will then give the slab its crown shape.
In addition to proper finishing and curing, flat slabs require proper jointing for crack control and load transfer. The joints should be placed at regular intervals, such as at 15 or 20 feet, around any open areas and at right angles to any walls or columns.
