New concrete can be cast into any shape, design, and finish using various finishing techniques and specialised tools to make it more aesthetically pleasing.
Let’s discuss some of the common types of concrete finishes available today; from rock salt concrete finishes to brushed concrete finishes, and stamped concrete finishes.
1. Rock Salt Concrete Finishes
Rock salt concrete finishes are concrete finishes types obtained by inserting rough rock salt crystals – using rollers – on fresh concrete and washing it off once the concrete is cured.

This results in an attractive, rough subtle texture and skid-resistant concrete surface that is ideal for swimming pools and other wet surfaces such as bathroom floors.
2. Stamped Concrete Finishes
Stamped concrete finishes are concrete finishes types designed to resemble stones such as slate, brick, tile, or flagstones. They can also be made to look like wood.
These types of finishes are obtained by pressing the required pattern on freshly levelled concrete. They are widely used on floors in driveways, sidewalks, and carparks.
Stamped concrete finishes are also the most common patio concrete finishes.
3. Troweled Finishes
These are the most basic and common types of concrete finishes. They are obtained by moving a trowel over freshly poured concrete to create a smooth concrete surface.
4. Broom Finishes
Broom finishes are rough textured concrete obtained by dragging a broom on the troweled surface of fresh concrete. This creates small elevations that provide slip-resistance.
5. Exposed Aggregate Finishes
Exposed aggregate finishes are a type of concrete finishes where the top layer is removed to expose the aggregates without causing any adverse effect on the aggregate.

They are obtained by using a power floater or diamond polisher to remove a thin layer (a few millimeters) of concrete at the top of the partially cured concrete.
A premium grade of protective layer is then applied to provide the desired polished finish.
6. Polished Finishes
Polished finishes are obtained by crushing and polishing the concrete surface using specialized tools and a penetrant chemical to provide a unique texture.
7. Swirl Finishes
These are among the most brilliant types of concrete finishes obtained by spreading the concrete surface in a consistently overlapping circular pattern.
Swirl finish provides a beautiful surface ideal for outdoor applications. These finishes provide safer walk when compared with smooth concrete finishes especially during the rainy season.
8. Colored Finishes
As the name suggests, colored finishes are obtained by adding pigments to the concrete mix before pouring, or through post-cure staining to provide colorful concrete surfaces.
A stained colored finish can be achieved by applying stains to already cured concrete to achieve a more colorful finish.
Thereafter, a seal should be installed over the concrete to protect the surface.
