What is the purpose of a power trowel?
A power trowel consists of one or multiple rotating blades enclosed by a safety cage. This type of concrete finishing equipment is used to create a polished, level finish on a variety of concrete surfaces. Floating, finishing, and combination blades are used to create the desired end result.
Why do you power trowel concrete?
A power trowel, also known as a power float, is a piece of construction equipment used to apply a smooth finish to concrete slabs. With every concrete pour troweling is important, because it allows the concrete to continue the process of finishing the concrete and squeezing residual water out of the concrete.
Is a power trowel necessary?
These pathways or vents allow the moisture within the concrete slab to move out and finally evaporate from its surface. As a result, a smooth surface can be achieved. In small areas, you can even use hand trowels, but for larger areas, you would need a power trowel.
How do power trowels move?
The operator has two steering control levers to move the machine. Moving both levers into the back position allows the power trowel to move backwards. Moving the right handle to the left moves the machine to the left, and moving the right handle to the right moves the unit to the right.
What is power trowel in construction?
A power trowel (also known as a “power float” and “troweling machine”) is a piece of light construction equipment used by construction companies and contractors to apply a smooth finish to concrete slabs.
When should you trowel concrete?
Trowel the surface Smooth the surface with a steel trowel after it’s partially hardened. Hold the trowel almost flat and swing it in large overlapping arcs while applying pressure. Float the concrete when you’re done grooving and edging (Photo 6).
How long do you leave concrete before floating?
CURE AND SEAL THE CONCRETE Once you’re done with finishing, let the concrete dry and achieve full strength, this is called curing. You can use your concrete for light foot traffic 3 to 4 days after placement, and you can drive and park on your concrete after 5 to 7 days, but curing isn’t complete until the 28 day mark.
What happens if you finish concrete too soon?
More often, premature finishing or improper first (bull floating) or second floating results in trapping rising bleed water and air below the top surface of the concrete (Image 2). When this occurs, the resulting weak or soft zone below the surface causes the top surface of the concrete to flake or scale off.
What is the lowest temperature that you can pour concrete?
Experts agree—the best temperature to pour concrete is between 40° – 60°F. When temperatures dip below 40°F, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete.
What is the difference between a spade and a trowel?
As nouns the difference between trowel and spade is that trowel is a mason’s tool, used in spreading and dressing mortar, and breaking bricks to shape them while spade is a garden tool with a handle and a flat blade for digging not to be confused with a shovel which is used for moving earth or other materials.
Why do you power float concrete?
A power float is a hand-operated machine used to produce a smooth, dense and level surface finish to insitu concrete beds. Power floating eliminates the time and materials needed to apply a finishing screed and is quicker and less labour-intensive process than hand trowelling.
When should you use a power float?
When to power float concrete Among the best power trowel finishing techniques, before using it, we recommend stepping on the concrete when it has started to dry. Your surface is ready to power float when your footprint is ¼” deep or a bit less and it doesn’t bleed much water.
What is a trowel finish on concrete?
Trowel-finished concrete floors are seamless surfaces that recreate the concrete effect. They can be applied to any kind of surface, indoor and outdoor, horizontally or vertically. The decorative effects that can be obtained with a trowel-finished concrete surface are several and always customizable.
What trowel do I use for drywall?

How do you make concrete smooth after it dries?
These are the 4 steps in how to smooth concrete after it dries: Remove all imperfections on the surface. Vacuum up all debris and apply the adherent. Apply a new layer of concrete. Sand the surface and wash the concrete. Apply a layer of vitrifier to protect the concrete.
