How to Keep Concrete Dye from Fading
Concrete dyes are an attractive way to add color to a concrete floor. However, because of the nature of dye — it penetrates the porous surface to create color, rather than reacting chemically with the concrete — contractors can conduct a few assessments and tests at the job site before determining whether a concrete dye is the right product for the job:

  1. Type of Concrete. Typically, a pure color dye will change slightly, due to the minerals in the concrete, taking on a lighter or darker shade, which can also change with time. Adjust the dye color to the type of concrete for the desired shade.
  1. UV Light Stability. Sunlight can damage dyed concrete floors, causing vibrant colors to fade. Check if windows in the room are made with glass containing UV-protection, which can keep floor color from fading.
  1. Moisture Vapor Test. When moisture in concrete brings salts to the surface, it causes dyes to seep deeper into the floor, diluting their color. Testing for efflorescence cannot only root out a bigger moisture issue, it indicates whether water will cause the color to diminish.
  1. Use Stain. Concrete stains work differently than dyes, reacting chemically with the concrete to create color that is more resistant to fading from sunlight or moisture.
  1. Apply Guard. A proper guard provides long-lasting, breathable protection for the floor and its color. Apply after polishing. 

Fixing Faded Floors
If the concrete floor is already fading:

  • Clean and seal the flooring surface to stop additional fading
  • Remove the sealer, then re-dye the floor and protect with sealer
