Acid Wash Concrete Floor DIY: A Guide to Revamp Your Floors

Concrete floors have been a popular choice for many homeowners and businesses due to their durability and low maintenance. However, over time, they can become dull and stained, giving an unappealing look to your space. If you’re looking for an affordable way to revamp your floors, acid washing can give your concrete floors a new life. Not only does it remove stains and dirt, but it also adds an attractive texture that can complement your interior design.

In this article, we’ll delve into the world of acid wash concrete floor DIY and provide you with a comprehensive guide to give your floors a fresh new look.

What is Acid Wash?

Acid washing is a method used to give concrete floors a unique and attractive texture. It involves applying an acidic solution to the concrete surface, which reacts with the minerals in the concrete to create a mottled and textured effect. The acid solution etches the surface of the concrete, removing any stains, dirt, and other unwanted marks, leaving a fresh and clean surface.


Before starting the acid washing process, there are a few things you need to do to prepare your floors:

  • Clean the floor thoroughly to remove any dirt, debris, and stains. Use a pressure washer or a scrub brush to remove any stubborn stains.
  • Remove any existing sealers or coatings using a chemical stripper or a floor grinder.
  • Repair any cracks or damages in the concrete using a concrete patching compound.
  • Protect any nearby surfaces, such as walls and furniture, from the acid solution by covering them with plastic sheets or drop cloths.
  • Wear protective gear, such as gloves, goggles, and a respirator, when handling the acid solution.

Acid Washing Process

The acid washing process involves the following steps:

  1. Mix the acid solution according to the manufacturer’s instructions. Typically, the solution is a mixture of hydrochloric acid and water.
  2. Pour the acid solution onto the floor in small sections, starting from the farthest corner of the room and working your way towards the exit.
  3. Use a stiff-bristled brush or a broom to spread the acid solution evenly over the surface. Make sure to wear protective gloves and goggles during this step.
  4. Let the acid solution sit on the surface for 10-15 minutes, depending on the severity of the stains and dirt.
  5. Using a garden hose or a pressure washer, rinse the acid solution off the surface. Make sure to rinse thoroughly to remove any residual acid solution.
  6. Neutralize the surface by applying a baking soda solution to the surface. This will help to neutralize the acid and prevent any further etching.
  7. Rinse the surface again with water and let it dry completely.
  8. Apply a sealer or coating to the surface to protect it from future stains and damages.
