The correct sequence of steps in slab finishing, which includes pouring, screeding, floating, edging, jointing, and troweling, is essential for achieving a high-quality surface that meets both aesthetic and functional requirements.

Beginning with the pouring of concrete marks the start of the process, ensuring the slab is placed in the desired area. After pouring, screeding follows, which involves leveling the surface of the wet concrete to eliminate excess material and create a uniform thickness. This step is critical as it lays the foundation for the rest of the finishing process.

Once the slab is leveled, floating is performed. This involves using a float to further smooth the surface and consolidate the concrete. Floating also helps to bring fine particles upwards, enhancing the surface quality.

After floating, edging is performed, which involves using an edging tool to create a finished edge along the perimeter of the slab. This step is vital for preventing cracking at the edges and providing a neat, aesthetically pleasing finish.

Jointing is then completed to control cracking due to shrinkage or temperature changes in the concrete. By creating intentional cracks, the concrete’s integrity can be maintained while controlling where future cracking occurs.

Finally, troweling is done to achieve a smooth and dense surface finish. This
