The Process of Concrete Finishing
After laying concrete, it’ll want to be leveled. A board is dragged throughout the pinnacle to make it despite the paperwork.
Then it’s smoothed with a wooden float: now no longer best does this enhance its appearance, it additionally makes it more potent through using the bigger stones into the cement even as bringing the finer particles (sand and grit) to the pinnacle.
Then the cement is separated from the shape and joints are created: cement shrinks because it hardens, so joints save you from it cracking.
At this point, you can broom the floor to create an ornamental brushed texture. Lastly, it ought to be left on my own to dry.
