Can you finish concrete with a float?
Float the concrete when you’re done grooving and edging (Photo 6). Floating removes the marks left by edging and brings the surface one step closer to a final finish. You may have to bear down on the float if the concrete is starting to harden.
What is the difference between float and trowel?
A float has a thicker base than a trowel and is usually made of plastic, sponge, rubber, wood or magnesium – a lightweight pale grey metal. It’s used to even up the surface on plaster or concrete, make it firmer and give whatever texture is required. The finish will depend on the float chosen.
What is the difference between power float and power trowel?
A power trowel, also known as a power float, is a piece of construction equipment used to apply a smooth finish to concrete slabs. There are two types power trowels, ride on power trowels and walk-behind power trowels. A ride on power trowel is used with an operator sitting on a seat and controlling the power trowel.
What is the purpose of floating concrete?
Floating has to be done on virtually every concrete job after concrete is poured and leveled. (Leveling is usually accomplished with a screed.) When done properly, floating pushes the aggregate down into the concrete and encourages moisture to rise, helping the concrete dry and creating a smoother surface.
When should you float a concrete surface?
It is important to float the concrete before excess moisture or bleed water rises to the surface and accumulates. Excess water can significantly weaken concrete; therefore, floating must occur before too much water bleeds to the surface.
Can you just bull float concrete?

When should I trowel concrete?
In the concrete finishing process, troweling is done after floating, and after the bleed water has evaporated. Floating diminishes the number of high spots and reestablishes moisture in the surface mortar that was lost due to evaporation.
Do I need a finishing trowel?
A finishing trowel is an important tool for many types of construction. It’s used to smooth out materials like mortar, plaster, and concrete. It has a very straight, angled blade designed to fit precisely into right angles and smooth out the surface of the mixture in straight lines.
Can you finish concrete without a power trowel?
The ideal smooth and even surfaces on freshly poured concrete can be achieved by processing it before it dries. For small surface areas a hand trowel can be used, but for larger areas Walk-Behind Power Trowels, or even Ride-On Trowels are a much better option, because they are much faster and more efficient.
When should I use power trowel on concrete?
Power trowels are typically used when concrete slabs are too large to be finished by hand trowels.
How long do you wait to float concrete?
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.

When should you bull float concrete?
Darbying or bull floating should be done immediately after “screeding”, or after the concrete has been tamped if tamping was done. This process should be finished before excess moisture or bleedwater appear on the surface.
How long should you wait to broom finish concrete?
When it comes to brooming, timing is critical—brush too early and the surface will be weak, brush too late and there won’t be enough texture. It must be done while the slab is still soft, but after the bleed water has dissipated. Depending on the weather, this can take anywhere from 20 minutes to 4 hours.
What is finishing trowel used for?
Finishing trowels are used for smoothing out materials like cement, plaster, etc.
Do I need a flexi trowel?
The flexible trowels are beautiful to use and always provide a cracking finish. However, you need a stiff trowel to apply and flatten your plaster with. You need the good old trusty standard, old school trowel because without it you’d be ruined.
How long after pouring concrete can you float it?
Allow all of the water to disappear before you do anything else. This can take 20 minutes or 4 hours depending on the temperature, humidity and how hard the wind is blowing. After the bleed water is all gone you can get out your steel finishing trowel and put on the final touches.
What are four 4 types of concrete surface finishes?
Now with the basic understanding of what makes concrete, next you will learn the four basic concrete finishes
- Slick Troweled Concrete.
- Broom Finished Concrete.
- Exposed Aggregate Concrete.
- Stamped Concrete. (CLICK Above ☝ For Ultimate Guide to Stamped Concrete?)
- Decorative Concrete.
How long does 4 inches of concrete take to cure?
The general rule of thumb is that concrete takes about 28 days to dry for every inch of slab thickness. Within 24 to 48 hours, the concrete will be ready for foot traffic.
What happens if you dont water concrete?
Concrete that is not moist-cured at all dries too rapidly, and reaches less than half its potential design strength. It will also have a greater number of shrinkage cracks.
Is trowel finish concrete slippery?
Trowel-finished concrete floors are slip-resistant
The trowel-finished concrete floor’s particular rough texture and high-adhesion make it a slip-resistant surface. For this reason the trowel concrete floor is ideal for outdoor applications such as pooldecks and walkways.
What is the best way to finish concrete?
HOW TO FINISH CONCRETE
- Spread the concrete. Use a square shovel or a come-along tool to push and pull the wet concrete into place.
- Screed the concrete. During this step remove excess concrete and bring the surface of the concrete to proper grade.
- Float the surface.
- Edge the slab.
- Groove in joints.
- Trowel the surface.
Can you trowel concrete too much?
If you haven’t done this before or only done it a few times you are likely to make two mistakes; troweling too soon and troweling too much. Both of these have the effect of pulling fines and water to the surface. This can lead to a weakened surface, tiny cracks and a white dusty surface.
