Four common types of concrete surface finishes include Broom Finish, Stamped Concrete Finish, Salt Finish, and Exposed Aggregate Finish. These finishes not only enhance the aesthetic appeal of concrete surfaces but also offer practical benefits such as improved slip resistance and durability.
Concrete finishes are specialized treatments applied to the surface of fresh concrete to achieve a desired texture, appearance, and functionality. From practical slip-resistant surfaces to decorative artistic expressions, the choice of finish significantly impacts the final look and performance of concrete installations. Understanding the characteristics of each can help in selecting the ideal option for various applications, whether for driveways, patios, walkways, or interior floors.
Popular Concrete Surface Finishes
Here's a quick overview of some widely used concrete finishes:
| Finish Type | Key Characteristic | Primary Benefit | Typical Applications |
|---|---|---|---|
| Broom Finish | Textured with a broom | Excellent slip resistance, cost-effective | Driveways, sidewalks, ramps, pool decks |
| Stamped Finish | Replicates natural materials like stone/brick | High aesthetic appeal, wide design versatility | Patios, walkways, driveways, indoor floors |
| Salt Finish | Creates small, pitted textures with rock salt | Unique subtle texture, enhanced grip, decorative | Pool decks, patios, walkways |
| Exposed Aggregate | Reveals natural stones within the concrete | Durable, naturally attractive, good traction | Driveways, pool decks, sidewalks, plazas |
Let's delve deeper into each type:
Broom Finish
The Broom Finish is a classic and widely utilized concrete surface treatment known for its practicality. It is created by dragging a specialized concrete broom across the freshly placed and leveled concrete surface, forming a series of parallel lines or grooves. The depth and spacing of these grooves can vary depending on the type of broom used and the desired texture.
- Key Benefits:
- Enhanced Slip Resistance: The textured surface significantly improves traction, making it ideal for outdoor areas prone to moisture.
- Cost-Effective: It is one of the most economical concrete finishes to achieve.
- Durability: The finish does not compromise the inherent strength and longevity of the concrete.
- Typical Applications: Driveways, sidewalks, ramps, pool surrounds, and any area where safety from slips and falls is a primary concern.

Stamped Concrete Finish
Stamped Concrete Finish, also known as patterned concrete or imprinted concrete, is a highly decorative technique that mimics the appearance of more expensive natural materials such as brick, slate, flagstone, cobblestone, wood, and tile. This is achieved by pressing flexible mats with pre-designed patterns into wet concrete. The concrete is often colored with integral colors, color hardeners, or stains to further enhance the resemblance to natural stone or other materials.
- Key Benefits:
- Aesthetic Versatility: Offers a vast array of patterns, textures, and colors to match any architectural style.
- Cost-Effective Alternative: Provides the look of natural stone or pavers at a fraction of the cost and with less maintenance.
- Durability: Concrete's inherent strength ensures a long-lasting and resilient surface.
- Typical Applications: Patios, pool decks, driveways, walkways, interior floors, and commercial plazas.

Salt Finish
A Salt Finish provides a distinctive, subtle texture that is both visually appealing and functional. This finish is created by broadcasting coarse rock salt crystals onto the surface of freshly floated concrete. Once the concrete has set but not fully cured, the surface is washed with water, dissolving the salt crystals and leaving behind small, randomly spaced pits or indentations. The size of the pits depends on the granularity of the salt used.
- Key Benefits:
- Unique Aesthetic: Offers a one-of-a-kind speckled or pockmarked appearance that can be quite elegant.
- Improved Traction: The subtle texture enhances grip, making it a good choice for wet areas.
- Durable: Like other concrete finishes, it contributes to the longevity of the surface.
- Typical Applications: Pool decks, patios, walkways, and areas where a distinctive, understated non-slip surface is desired.

Exposed Aggregate Finish
The Exposed Aggregate Finish showcases the natural beauty of the aggregates (gravel, stone, or sand) mixed into the concrete. This finish involves removing the thin layer of cement paste from the surface of freshly placed concrete to reveal the underlying decorative aggregates. This can be achieved through various methods, including washing, abrasive blasting, or using chemical surface retarders. The type, size, and color of the aggregates can be chosen to create diverse visual effects.
- Key Benefits:
- Natural Beauty: Highlights the inherent beauty of the stones, creating a textured, natural look.
- Exceptional Durability: Highly resistant to wear and tear, making it suitable for high-traffic areas.
- Excellent Traction: The rough, textured surface provides superior slip resistance.
- Typical Applications: Driveways, sidewalks, pool decks, patios, architectural panels, and public plazas.
