How to Acid Stain Outdoor Concrete

Acid staining is a popular technique for enhancing the appearance of outdoor concrete surfaces. It involves applying a chemical solution to the concrete, which reacts with the minerals in the concrete to produce a unique and colorful finish. Acid staining is relatively easy to do and can be completed in a weekend with the right tools and materials.

Here are the essential steps on how to acid stain outdoor concrete:

1. Prepare the Concrete Surface

The first step is to prepare the concrete surface for staining. This involves cleaning the concrete to remove any dirt, debris, or oil. Once the concrete is clean, it should be etched with a muriatic acid solution. Etching the concrete will help the acid stain to penetrate the concrete more evenly.

2. Choose the Acid Stain Color

There are a wide variety of acid stain colors available, so you can choose the color that best suits your taste. When choosing a color, it is important to consider the color of the concrete and the overall look you are trying to achieve.

3. Apply the Acid Stain

Once you have chosen the acid stain color, you can apply it to the concrete. The acid stain should be applied in a thin, even coat. You can use a brush, roller, or sprayer to apply the acid stain.

4. Let the Acid Stain Dwell

Once the acid stain has been applied, it should be allowed to dwell for a period of time. The dwell time will vary depending on the type of acid stain and the desired color intensity. Generally, the dwell time will be between 1 and 4 hours.

5. Rinse the Acid Stain

After the dwell time has expired, the acid stain should be rinsed off the concrete with water. The concrete should be rinsed until the water runs clear.

6. Seal the Acid Stain

Once the concrete has been rinsed, it should be sealed to protect the acid stain finish. There are a variety of sealers available, so you can choose the sealer that best suits your needs.

By following these steps, you can achieve a beautiful and durable acid stained concrete finish that will last for many years to come.
