Pros and Cons of Acid-Stained Concrete

Pros and Cons of Acid-Stained Concrete

If you are looking to spruce up your concrete floor, you may consider acid staining a viable option. Over the years, acid-stained concrete has become one of the most popular decorative flooring options for both residential and commercial establishments. This type of flooring gives old, dull concrete a new shine and a modern look. The process uses special acids and coatings that seep into the concrete surface and chemically alter the overall colour.

While there are other flooring options available at a comparable price-point, here is a list of pros and cons to consider before investing in acid-stained concrete.


  • Increases Aesthetic Value – Concrete stains come in different shades (pastels, neutrals, and deep tones), which add to the aesthetic of your floor. Instead of installing new flooring, professional contractors can enhance the original look of the floor by adding marbling, swirls, waves, or stenciled design.
  • Cost-Effective – While staining a floor may not be extremely cheap, it is relatively cost-effective in comparison to other flooring options. Concrete staining allows you to make the most out an older floor, instead of investing in new carpet, installing tiles, or laying hardwood on top of worn concrete.
  • Combine with Other Flooring Finishes – Apply stain before the concrete polishing process to achieve a durable, glossy finish that is great for areas with high traffic. You can also use a clear urethane coating to protect the surface from stains and scratches.


  • Not a DIY Project-Friendly for Commercial Spaces – Adding visual effects, like marbling, requires the skill of a professional flooring contractor. Once the acid stain is applied, you will only have a few seconds to create the desired pattern.
  • Does not Cover Imperfections – The imperfections of your floor, like cracks and discolouration are not improved by acid staining the way paint or pigmented epoxy coating can. This is why it’s crucial to prepare the floor before treating the surface with acid stain. However, if you are dealing with an unevenly coloured floor, it may be easier to look into other flooring options.
  • Purely Aesthetic – Staining the concrete does not improve the durability of the floor or its resistance to stains, spills, and abrasions. If you are looking to protect your floor, combine acid staining with another method, or choose a decorative epoxy coating.
