Sand wash finish concrete is a great way to add texture and depth to your concrete surfaces. It’s perfect for driveways, patios, walkways, and other outdoor spaces, and can even be used indoors. The finish is achieved by washing away the surface layer of the concrete to expose the aggregate underneath. This creates a rough, textured surface that’s both durable and attractive.
If you’re interested in using sand wash finish concrete to transform your home, here’s what you need to know:
Preparation
Before you begin, make sure the surface you’re working on is clean and free of debris. You should also ensure that the concrete has cured properly and is in good condition. If there are any cracks or damage, these should be repaired before proceeding.
Mixing the Concrete
Mixing the concrete for sand wash finish requires a slightly different approach than regular concrete. You’ll need to use a mix with larger aggregate, typically around 3/8″ in size. The mix should also be a bit wetter than regular concrete to make it easier to work with.
Pouring and Leveling
Once the mix is ready, pour it onto the surface and spread it out evenly using a screed. Be sure to work quickly, as the wetter mix will begin to set faster than regular concrete. Use a bull float to level and smooth the surface, and create a slight slope to ensure proper drainage.
Applying the Sand Wash
After the concrete has been leveled and smoothed, it’s time to apply the sand wash. This is done by broadcasting a layer of sand over the surface, then using a float to press it into the concrete. The sand should be evenly distributed and should cover the entire surface. Work quickly, as the concrete will begin to set soon after the sand wash is applied.
Washing the Surface
After the sand wash has been applied, allow the concrete to set for a short time, then begin washing away the surface layer. This is typically done with a pressure washer, although a hose and scrub brush can also be used. Start in a corner and work your way across the surface, applying a consistent amount of pressure to ensure an even finish.
Sealing the Surface
Once the surface has been washed and allowed to dry, it’s important to seal it to protect against damage and staining. There are many different types of sealers available, so be sure to choose one that’s appropriate for your specific needs.
Maintenance
To ensure that your sand-wash finish concrete lasts for many years to come, it’s important to perform regular maintenance. This includes keeping the surface clean and free of debris, as well as resealing the surface as needed.
Conclusion
Sand-wash finish concrete is a great way to add texture and depth to your concrete surfaces. Whether you’re looking to create a unique look for your patio, walkway, or driveway, this technique can help you achieve the results you’re looking for. With the right preparation, mixing, pouring, and washing, you can create a beautiful, long-lasting surface that will enhance the appearance of your home and property for years to come.
