The most basic type of concrete finish is a smooth surface created through the use of screeds and trowels. Immediately after concrete has been placed in forms, concrete finishers utilize a screed to level out the concrete surface.
What is mean by finishing of concrete?
Finishing may be defined as the process of leveling, smoothing, compacting and otherwise treating surface of fresh concrete or recently placed concrete to produce desired appearance.
When should you finish concrete?
When all traces of the water are gone and the concrete starts to harden, you can resume finishing activities. Test by pressing your gloved thumb onto the surface near the perimeter. The concrete is ready when pressing hard only leaves a 1/4-in.
What is place and finish concrete?
Replace damaged, eroded concrete or asphalt with partial or entirely new slabs or pads. Set your floors so that they withstand time, traffic, earthquakes and other forces.
What is the purpose of finishing concrete?
The primary purpose for finishing concrete pavements is to remove any small surface imperfections and seal the surface of the slab.
What are the different types of concrete finishes?
Types of Concrete Finishes
- Troweled Finish. Trowel finish is the most common and popular finish of concrete used for major types of applications.
- Broom Finish.
- Stamped Concrete Finish.
- Salt Finish.
- Exposed Aggregate Finish.
- Swirl Finish.
- Polished Finish.
- Colored Finish.
When should you broom finish concrete?
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.
How do you finish concrete 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.
How long should you wait to broom finish concrete?
Wait for all of the water content to disappear before broom finishing concrete. Depending on the humidity, temperature and wind condition, you may have to wait anywhere from 30 minutes to 5 or 6 hours.

Concrete should be allowed to flow slowly into the forms at a vertical angle.
What is the purpose of finishing?
Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction.
What is the purpose of finishes?
Finishes are used in the final part of the construction or manufacturing process, forming the final surface of an element. They can protect the element they finish from impact, water, frost, corrosion, abrasion, and so on, and/or they can be decorative.
