1. Add Color and Interest To Your Home With Acid Stained Concrete
.
Make sure you have the following materials before you begin transforming the concrete in your home: acid stain, concrete sealer, safety glasses, mask, bucket, sponge, broom, paintbrush, plastic sheets, and a garden sprayer (if applicable).
The next step is to prepare the concrete surface for the acid stain. This includes sweeping away dirt and debris, ensuring the surface is clean. If needed, pressure-wash the concrete as well. At this point, you can either score the concrete or apply a concrete etching solution. This will allow the acid stain to penetrate more evenly and deeply.
After prepping the space, you can begin to apply the acid stain. Wear safety glasses, mask, and gloves before working with acid stain. Mix the acid stain before starting to ensure even application. Acid stain is applied by spraying or painting the surface. You can then spread it with a brush, roller, or dried, clean broom. Make sure to not allow puddles of acid – continue to brush until the acid is evenly distributed on the concrete.
- Allow the acid stain to react with the concrete for 8-14 minutes. When fully satured, rinse off with clean water.
- Apply a concrete sealer used specifically for acid stains afterwards.
- Allow the sealer to dry completely before adding furniture, rugs, or any other items to the surface.
Creating an acid stained floor or surface can be time consuming. But with the right materials and proper preparation, your results will be something unique and beautiful that your guests won’t be able to take off their eyes from.
2. What You Need to Know Before Starting Your Acid Staining Project
Acid staining is a unique and interesting way to customize your concrete project. But before starting the process it’s important to understand what’s involved. From the supplies you’ll need, to the steps of the process and safety precautions.
Here are some key points to be aware of:
- Test Your Concrete: Check your concrete’s pH and moisture prior to staining. Stains may not achieve ideal results on concrete with a pH or moisture level that is too high or too low.
- Choose Your Color: Acid staining gives you a natural finish, so you can choose from a wide range of browns, reds, and greens. If you choose to mix colors, be aware that the more concentrated stain may overpower the lighter shade.
- Protect Your Skin and Breathe in a Safe Place: Acid staining requires the use of etching and stain products — both of which contain potentially dangerous chemicals. Always wear protective gloves, glasses, and a face mask. Additionally, work outside or in a well-ventilated space.
Once you’ve prepared the surface by cleaning and removing sealant, you’ll be ready to acid stain. To ensure the best results, use a sprayer or roller to apply the stain evenly over the concrete, and then working quickly, distribute the color with a broom or brush. It’s important to note that the final colors won’t be visible until the stain is completely dry.
No matter what the project, knowing the steps and supplies needed for a successful outcome is essential.

3. Preparing The Concrete Surface for Staining
Cleaning and Etching
Before you can apply a concrete stain, you need to prepare the concrete surface. The first step is to thoroughly clean the concrete with a mixture of warm water and a detergent that is made for concrete. Once the floor has been thoroughly cleaned, you’ll need to etch it. You can do this with an acid etching solution. After spraying the acid on the concrete, allow it to sit for 10 to 15 minutes, then rinse the surface with a pressure washer.
Removing Contaminants
You’ll then need to remove any potential contaminants from the concrete surface. This includes things like dirt, oil, grease, paint, and sealers. The easiest way to do this is to use a high-powered pressure washer and a degreaser. Be sure to let the degreaser sit on the surface for 10 to 15 minutes before rinsing it away with the pressure washer.
A Final Rinse
After removing any contaminants, it is essential to give the concrete a final rinse with clean water. This will help to remove any residual etching solution, detergent, and degreaser. After rinsing the concrete, allow it to dry completely before you start staining. This could take up to 24 hours.
Useful Tips
- Make sure to wear protective gear when etching and cleaning concrete.
- Take care when using a pressure washer as it can be powerful and damage the floor.
- Make sure the concrete is completely dry before you start staining.
Once you’ve followed these steps, your concrete surface should be prepared and ready for staining. Now it’s time to start creating a unique look with concrete stain.
4. Applying the Acid Stain to Your Concrete
Applying acid stain to your concrete surface is the last step in creating the unique, marbled affect that you desire. By executing this last step with the utmost attention to detail and following the instructions outlined in this article, you can ensure that you get the most desirable outcome possible.
Before you start applying the acid stain, it is important to give the concrete surface a good cleaning. Be sure to use a pressure washer to completely remove any dirt and debris, and take the time to mop the surface down with a clean cloth. After that, spray down the surface with a light mist of water to dampen the area.
Now you are ready to start applying the acid stain:
- Pour the acid stain onto the concrete in a crosshatch pattern. Make sure that you keep the puddles from merging together.
- Use a paintbrush to spread the stain onto the concrete in a uniform fashion.
- Once the stain has been absorbed completely, spray on additional stain as needed to achieve the desired marbling affect.
- Do not over-saturation the concrete, or else you will have to repaint or re-seal the surface.
Once you have successfully applied the acid stain to the concrete, you will want to seal the surface with a sealer. This will help protect the surface from dirt and debris, as well as ensure that the marbled affect is preserved for years to come.
5. Neutralizing The Acid
Once operations functioning on acid-stained concrete surfaces have been completed, the acid must be neutralized cleanly and effectively. This is a crucial step to achieve the stunning aesthetics that acid-stained concrete promises. Unneutralized surfaces lead to inferior, dull-looking results, thus abiding by a few simple steps will bring you desired results.
Available Tools
- Neutralizer (for most acids)
- Larger brush (for stubborn areas)
- Garden Hose
- Well-functioning Pump
Steps to Neutralize
- Rinse the acid completely with a garden hose or a pressure washer. Depending on the pressure applied, the entire rinse process should not take more than 10 minutes.
- Apply Neutralizer evenly on the surface. Use a pump or a spray bottle to facilitate application. Its important to ensure that the neutralizer reaches each nook and cranny of the surface effectively.
- Wait for 10-15 minutes, and use a brush or a scrub brush to remove any stain that still remains on the surface. This step ensures a uniform look to the stained area.
- Rinse the surface again with the pump or a garden hose. Wait for the surface to dry completely before proceeding with sealing the stained surface.
Always use protective gear while proceeding with your acid-staining process. Neutralizing is also an equally important process and should be given just as much attention. Making sure that all the equipment is functioning correctly and the surfaces are stained and neutralized in the correct manner are the hallmarks of aesthetic acid-stained concrete surfaces.
6. Enhancing Your New Finish With Colored Sealers
Adding a colored sealer to your newly acid-stained concrete is an excellent way to bring out the vibrancy of the stain and protect the finish from wear and tear. Here are a few tips for choosing and applying the right kind of sealer to your concrete:
- Choose the right sealer for your project: There are different types of sealers and each is designed for a specific purpose. Most colored sealers are engineered to bring out the beauty of the decorative concrete. For a more natural look, go with a penetrating sealer.
