Step-by-step process of power floating concrete
Power floating concrete is done in four steps using different tools and equipment.
Step 1: Begin with a bull float: Start by using a bull float to level the concrete surface. A bull float is a large, flat tool made of aluminum or magnesium that is used to spread and level concrete. It is important to begin floating as soon as possible after the concrete has been placed to avoid drying out or cracking.
Step 2: Use a fresno trowel to create a smoother surface: After using the bull float, the next step is to use a fresno trowel. This is a large, flat trowel that is used to smooth the surface of the concrete. It is moved back and forth across the surface of the concrete to flatten and level it.
Step 3: Apply a magnesium float for finer finishing: The third step is to use a magnesium float. This tool is used to further refine the surface of the concrete, giving it a smoother finish. It is important to apply the magnesium float after the concrete has begun to set, but before it has completely hardened.
Step 4: Finish with a steel trowel for a smooth surface: The final step is to use a steel trowel. This is used to give the concrete a final, smooth finish. It is important to use the steel trowel when the concrete is just beginning to harden. If the concrete has already hardened too much, it will be difficult to achieve a smooth finish.
Tips for achieving a perfect finish
There are some useful tips that can help in achieving a perfect finish while power floating concrete.
- To achieve a uniform finish, it is recommended to work in small sections and complete each section before moving onto the next one: This will help to ensure that the finish is consistent throughout the entire surface. Working in small sections also makes it easier to control the amount of pressure being applied to the concrete, which is crucial for achieving a uniform finish.
- It is important to keep the trowel blades clean to avoid leaving unwanted marks on the surface: Any debris, such as small rocks or aggregate, can scratch or gouge the surface if it is caught between the trowel blade and the concrete. Keeping the trowel blades clean will prevent this from happening and help to achieve a smoother finish.
- Overworking the concrete can lead to a weakened surface and reduced durability. Therefore, it is important to stop power floating once the desired finish has been achieved. Power floating for too long can cause the concrete to become overworked and reduce its strength and durability. Knowing when to stop power floating is important to ensure that the concrete surface maintains its integrity and durability.
