Concrete Sand Finish Exterior: A Comprehensive Guide
When it comes to exterior finishes for concrete, the sand finish stands out as a popular choice for its unique aesthetic appeal and durability. This guide will delve into the various aspects of concrete sand finish exterior, including its benefits, application process, maintenance, and more.
What is Concrete Sand Finish?
Concrete sand finish, also known as sandblasted finish or sand-textured finish, is a decorative concrete finish that creates a rough, textured surface. It is achieved by adding sand to the concrete mix during the pouring process. The sand particles become embedded in the concrete, resulting in a durable and visually appealing finish.
Benefits of Concrete Sand Finish Exterior
There are several advantages to choosing a concrete sand finish for your exterior:
-
Enhanced Aesthetics: The textured surface of the sand finish adds a unique character to your exterior, making it stand out from traditional smooth finishes.
-
Durability: The rough texture of the sand finish helps to prevent cracking and chipping, making it a long-lasting option for exterior applications.
-
Low Maintenance: Concrete sand finish requires minimal maintenance, making it an ideal choice for busy homeowners or property managers.
-
Customization: You can choose from a variety of sand colors and textures to create a finish that complements your home’s style and design.
Application Process
Applying a concrete sand finish requires careful planning and execution. Here’s a step-by-step guide to help you through the process:
-
Prepare the Substrate: Ensure that the concrete surface is clean, dry, and free of any debris or contaminants.
-
Mix the Concrete: Follow the manufacturer’s instructions to mix the concrete with the appropriate amount of sand. It’s essential to maintain the correct ratio for the desired finish.
-
Pour the Concrete: Pour the concrete mixture onto the prepared surface, ensuring that it is evenly distributed.
-
Smooth the Surface: Use a trowel or screed to smooth the concrete surface, removing any air bubbles and ensuring a level finish.

Apply the Sand: Immediately after smoothing the concrete, sprinkle the sand over the surface. Use a broom to sweep the sand into the concrete, ensuring an even distribution.
-
Remove Excess Sand: After the sand has been swept into the concrete, use a stiff brush to remove any excess sand from the surface.
-
Allow to Cure: Let the concrete cure for the recommended duration, typically 28 days, to ensure proper strength and durability.
Maintenance
Maintaining a concrete sand finish exterior is relatively straightforward:
-
Regular Cleaning: Sweep the surface regularly to remove debris and prevent the buildup of dirt and grime.
-
Pressure Washing: Periodically pressure wash the surface to remove stubborn stains and dirt. Use a low-pressure setting to avoid damaging the finish.
-
Sealing: Apply a concrete sealer every few years to protect the finish from UV rays, stains, and other environmental factors.

The cost of a concrete sand finish exterior can vary depending on factors such as the size of the project, the quality of materials, and labor costs. On average, you can expect to pay between $4 and $8 per square foot for materials and labor.
