When it comes to having a long-lasting and beautiful concrete coating, it’s all in the preparation. One of the most important steps to take during the process is the neutralization of the surface after applying an acid stain. Neutralizing the concrete surface will balance the surface pH. For concrete surfaces to look good, and adhere properly, the surface pH must be neutralized post staining process.
Below we will discuss neutralizing acid stains and preparing the concrete surface for coating, and preparing for color and protection.

Why is it Important to Neutralize the Surface?
Acid stains chemically react with the minerals in concrete and create warm rich natural color tones. The chemical reaction of the acid stain will leave acidic residue behind that if not neutralized, may inhibit adhesion of the coating material to the concrete.
If the surface is not neutralized, the concrete coating, whether it be a sealer, acrylic stain, or clear top coat may not bond properly resulting in peeling or dull patches.
Neutralizing is simply restoring the surface pH balance to finish the surface off correctly and help provide a foundation for a smooth, even finish that lasts.

How to Make an Acid Stain’s pH Level Neutral
To neutralize the pH of an acid stain, use a basic baking soda and water solution.
First, get a small package of baking soda from your local grocery shop and fill a 5-gallon bucket with water. Mix the package of baking soda into the water until dissolved. Then, pour the solution evenly over the acid-stained concrete.
This helps to properly spread the baking soda solution and neutralize the acid. After you’ve agitated the whole surface and removed all acid stains, use a wet/dry vacuum to remove any remaining water. Finally, using just clean water, repeat the process without the baking soda to remove any leftover residue, then thoroughly dry the area.
Once the acid stain in the concrete has been neutralized, you will be ready to go on to the next phase in your concrete coating job.

Introducing Color and Contrasts
After neutralizing the concrete surface and allowing it to dry, you can achieve the desired color by using acrylic stains in complementary colors. For darker colors, there are now contrasting or lighter areas by adding and layering other colors at strategic places.
To introduce contrast or lighter areas to a darker acrylic stain, you start with the same neutralizing process again if you prefer. Then, once the surface has dried, apply the acrylic stains as per the manufacturer’s instructions. Keep in mind that you will need to let the surface dry before sealing the color process.
This process of layering allows you to have some control over a final color and helps create added visual depth to the concrete surface.

Seal and Protect the Surface
The last step is to simply seal the surface, once the desired color is achieved. A seal provides color enhancement, luster, protects the floor from moisture and wear, and UV rays.
A high-quality sealer is needed to get the most longevity from your concrete coating while keeping it looking great and protecting your investment. Regardless of whether the final finish is matte, satin, or gloss, sealing the surface will keep it looking great and easy to maintain.
Revitalize your coating
You can have a smooth, colorful, and long-lasting concrete surface by following the steps outlined above. Always remember to properly neutralize any acid stains, such as rinsing thoroughly and sealing the concrete properly with sealant. This ensures that all layers of your concrete coating adhere properly and achieve excellent results.
