Acid staining a concrete floor will allow you to create a marble pattern that lends both beauty and depth to your flooring materials. In order to complete this task and obtain the desired look, simply follow the steps outlined below.
What You Will Need
- Painters tape
- Masking paper
- Acid stain
- Safety gloves and eye wear
- 2 two-gallon plastic pumps with sprayer
- Clean mop
- Water-based sealer
Step 1: Prep The Area
In order to prevent damage to any household surfaces, you will need to remove all of the trim surrounding your concrete floor. You will also need to cover the walls and cabinets surrounding this floor using masking paper. To ensure the masking paper is secure, painters tape should be used both beneath the paper, as well as along each edge of the paper.
Step 2: Prep The Stain
Your acid stain will need to be mixed outdoors to ensure proper ventilation. The hydrochloric acid used in these stains can be quite dangerous if allowed allowed to touch your skin, so be sure to wear both safety gloves and goggles at all times. You may also want to wear a face mask in order to avoid breathing in the fumes produced by this acid.
When mixing your acid stain, be sure to always add the acid to the required amount of water, rather than adding the water to the acid. This will help to minimize splashing.
Step 3: Apply The Stain
Using an all-plastic pump and sprayer (this is important as acid will eat through metal), begin applying the acid stain to your concrete floor using random motions. Be sure to wet the entire floor thoroughly. However, you should also take care not to create puddles of acid.
As the lime in your concrete floor begins to react with the acid in the stain, you will see the color of your floor beginning to develop. This color will vary throughout the floor due to the different lime levels throughout the concrete. This is what allows the floor to take on a marble-like appearance.
Step 4: Neutralize The Acid
Once you have achieved the color that you want, you will need to neutralize the acid. This can be done by combining four parts water to one part ammonia in a clean plastic pump sprayer. This ammonia mixture should be applied to the entire floor and then mopped away using a clean mop.
Step 5: Seal The Floor
The final step in the process will be to seal your floor so that it is protected from damage during normal daily use. This should be done using a several thin coats of water-based sealant.
Once the sealer has dried, you will be able to reinstall your trim and remove the masking paper from your walls.
While concrete staining is a process that can be completed on a do-it-yourself basis, this DIY project will not be right for everyone. Due to the dangers associated with hydrochloric acid, inexperienced homeowners should not attempt this task. Instead, these homeowners should leave the concrete staining process to the professionals.
