Types of Concrete Finishes are
- Troweled Finish
- Broom Finish
- Exposed Aggregate Finish
- Salt Finish
- Polished Finish
- Colored Finish
- Stamped Concrete Finish
Trowel finish is the most common and popular finish of concrete used for major types of applications. After the concrete is laid in the formwork and leveled, the trowel is used to smooth and fine-level the surface of concrete.
Trowels are available in both manual and mechanical types. A manual trowel consists of a flat steel blade with an attached handle that is pushed and pulled across the concrete surface.
A mechanized trowel is used for large commercial projects which resemble large fans with the blades sitting directly
The broom finish of the concrete is rough textured finished obtained by dragging a broom on the trowelled surface of the concrete while the concrete is still fresh.
Dragging of broom on the fresh concrete surfaces creates small ridges that provide for traction control and slip-resistant.
Exposed Aggregate Finish
The construction of exposed concrete finish is to have leveled concrete floor surface, distribute aggregate evenly, and keep air voids to as minimum as possible.
Power Floater or Diamond Polisher is used to polish the top surface of the partially cured concrete. The equipment removes a concrete layer whose thickness does not exceed a few millimeters at the top of the concrete. A fine grade protection layer is applied to provide the favored polished finish.
The salt finish concrete surface is obtained by inserting coarse rock salt crystals using rollers on the freshly placed concrete surface and washing it off with streams of water after the concrete is set.
This finish gives a decorative, rough subtle texture and skid resistance to plain or colored concrete. It is mainly used for swimming pools or other wet areas.
The polished finish on a concrete surface is achieved by a mechanical process of grinding and polishing with the help of a penetrant chemical to provide different texture with the help of specialized tools and equipment.
The colored finish of the concrete is accomplished through mix-added pigments or post-cure staining to provide a pleasing look to match the surrounding environment.
The colored finish on a concrete surface can be carried out by either pigment or strains. The pigmented colored concrete can be accomplished by adding the pigments directly to the concrete mix prior to pouring.
The strained colored concrete can be obtained by applying stains to concrete of any age to obtain a more vibrant colored finish. The application of stain is typically followed up with the installation of a seal over the concrete to protect the surface.
Stamped Concrete Finish
The stamped concrete finish is obtained by pressing the required patterns on the freshly levelled concrete. This type of concrete finish after completion of their construction looks similar to stones such as slates or flagstones, brick, tile or with proper skill they can look similar to wood.
Stamped concrete finish is a very intelligent and innovative innovation in concrete widely applied for floor in patios, car porch, driveways and sidewalks.
