Exposed aggregate concrete is a type of concrete that has been treated with a special chemical or mechanical process to expose the inner stones and aggregate. This type of concrete is often used in driveways, patios, and walkways because of its durability and attractive appearance. To ensure that your exposed aggregate concrete stays looking great, it is important to follow a few simple maintenance tips.

First, make sure to regularly sweep away any dirt or debris that may accumulate on the surface of your exposed aggregate concrete. This will help to prevent dirt and other materials from becoming embedded in the concrete, which can eventually lead to staining and discoloration. 

Second, it is important to seal your exposed aggregate concrete every two to three years. This will help to protect the surface and keep it looking great. When sealing, make sure to use a sealer that is specifically designed for exposed aggregate concrete.

Third, if your exposed aggregate concrete is located in an area that receives a lot of sun, it is important to use a sealer that has a high UV protection rating. This will help to ensure that your exposed aggregate concrete does not fade in color over time.

Finally, if you notice any cracks or other damage to your exposed aggregate concrete, it is important to repair it as soon as possible. Cracks can allow water to seep into the concrete, which can cause further damage.
