Ok, I’m going to admit that this project has taken longer than I expected. It’s not because the process was long or anything, but after I started I ended up having sinus surgery which made me have to stay away from sanded concrete and the fumes until everything healed up nicely. Now that I’m all better and finally all finished I have this amazing diy acid stain concrete countertops project I want to share. I got tired of looking at our plain old bathrooms and decided it was time for a change. I completed this bathroom cabinet project first and then moved on to the countertops. I loved how it turned out and the color is gorgeous! Here’s my step-by-step for my diy acid stain concrete countertops for my bathroom and I’d like to thank the great people at Concrete Coatings for sponsoring today’s post. Enjoy!
How To Stain Concrete Countertops
What You Need
Concrete Coatings VIVID Acid Stain (I used the color Coffee)
Sander (I used an orbital sander and a ¼ Ryobi sheet sander)
Sand Paper (I used 150 grit for the orbital sander and 220 for the ¼ sheet sander)
Drywall Mud Pan
Plastic Trowel Spatula (I think that’s what they’re called)
Empty Spray Bottle
1 Small Roller Brush and 1 Large Roller Brush
Spray Bottle with 1 Part Ammonia to 1 Part Water
*Always wear gloves and a face mask. Work in a well-ventilated area.
Directions for DIY Acid Stain Concrete Countertops
Turn off water to the sink. Remove faucet fixtures. Line the walls near the countertop with painters tape. I removed the cabinet doors because it was easier for me to access the plumbing and I didn’t want accidentally getting any stain on my newly finished doors.
Using the orbital sander and 150 grit paper, sand down the countertop to remove the shiny finish. This gives the concrete a rough surface to adhere to.
Pour your desired amount of feather finish concrete into the mud pan. Slowly add water. I added a ½ cup at a time and constantly mixed until the consistency was like batter.
Using the plastic trowel, add a thin layer of concrete to the countertop. It will look patchy and uneven at first. Get into the corners with the edge of your trowel. Allow the first layer of concrete to dry. Apply the second layer of concrete, making sure it fill in any uneven spaces. Allow to dry.
Once the concrete is dry, use the ¼ Ryobi sheet sander and 220 grit paper to make the surface as smooth as possible. I’m going to admit that I didn’t do a good job smoothing it out the first time, so I had to sand it down some more. There are a few striations left, but it still looks nice.
Using the damp cloth, add moisture to the sink. This will allow the acid stain to settle into the pores of the concrete.
Add your desired amount of Concrete Coatings VIVID Acid Stain to your empty spray bottle. If you choose, you can dilute the acid stain with water if you want a lighter color. You can also mix colors from their line, if you choose to. Evenly spray the acid stain over the concrete in small sections, making sure that the solution doesn’t puddle in areas. Quickly use the small roller brush to spread the stain over the concrete before moving on to spray the next section. Continue this process until the entire countertop is stained.
Allow the stain to dry and react to the concrete, according to the time on the container. I waited at least 4 hours. Using the ammonia/water mixer, spray the counter to stop the reaction between the concrete and stain. Once dried, use a non-harsh liquid soap and water to remove any remaining residue. Allow to dry at least 24 hours to ensure all moisture is gone.
Using the Concrete Coatings Super Seal 2000 Acrylic Sealer and the larger roller brush, evenly spread the sealer on the countertop. Allow to dry. If the sealer doesn’t take in certain spots, then respray those spots with the ammonia mixture and allow to dry. Reapply sealer. Allow the countertops to dry for at least 24 hours before reattaching faucet and turning back on the plumbing.
Enjoy your beautiful new diy acid stain concrete countertop sinks!
