Dos for Curing Exposed Aggregate Concrete

Use a curing compound

One of the most important steps in curing exposed aggregate concrete is to use a curing compound. This compound helps to retain moisture in the concrete, preventing it from drying out too quickly and ensuring a strong, durable finish.

Keep the surface moist for at least 7 days

It is crucial to keep the surface of the exposed aggregate concrete moist for at least 7 days after it has been poured. This can be done by regularly spraying the concrete with water or using a garden hose to keep it damp. By keeping the surface moist, you are allowing the concrete to cure properly and prevent cracking or other damage.

Cover the concrete with plastic sheeting

Another effective method for curing exposed aggregate concrete is to cover the surface with plastic sheeting. This helps to retain moisture in the concrete and protect it from drying out too quickly. Make sure to secure the edges of the plastic sheeting to prevent it from blowing away in the wind. Covering the concrete with plastic sheeting can also help to regulate the temperature of the concrete, ensuring a more even and consistent cure.

Don’ts for Curing Exposed Aggregate Concrete

Don’t allow the surface to dry out too quickly

One of the most common mistakes when curing exposed aggregate concrete is allowing the surface to dry out too quickly. This can result in cracking, shrinking, and poor overall finish. To prevent this, it is important to keep the surface moist by using a curing compound or wet burlap throughout the curing process.

Don’t use water that is too hot or too cold

Using water that is too hot or too cold can also have negative effects on the curing process of exposed aggregate concrete. Extreme temperatures can cause the concrete to set too quickly or not set at all, leading to a weak and brittle finish. It is important to use water at a moderate temperature to ensure proper curing.

Don’t overwork the surface during finishing

Overworking the surface during finishing can result in a weak and uneven finish for exposed aggregate concrete. It is important to avoid excessive troweling or floating, as this can push the aggregate too far down and prevent it from being exposed properly. Instead, focus on achieving a smooth and level surface without overworking it.

In conclusion, caring for exposed aggregate concrete involves a combination of dos and don’ts to ensure its longevity and appearance. By following proper maintenance practices such as sealing, cleaning, and avoiding certain harmful substances, you can keep your concrete looking its best for years to come. Remember to regularly inspect and address any issues that may arise to prevent further damage. With the right care and attention, your exposed aggregate concrete can continue to enhance the beauty of your property for a long time.
