Dye Concrete Floors

Dye Concrete Floors

Concrete Dye is a water-based acid free finish and provides consistent color accuracy. It is available in 36 individual dye colors and it allows you to create your own custom color blends.For decorative contractors who use concrete as a canvas for color, the combination of chemical stains and concrete dyes is a perfect synergy. Dyes are often used in conjunction with acid stains to produce a variegated look and, in most cases, complement the already stained floor.

Dyeing floors is different from staining them. With dye, there is no chemical reaction with the concrete—it simply dyes the surface. Dyes can come in liquid form or as dry pigment, the latter to be mixed with a solvent (usually acetone). The color of the finished product and the depth that the dye penetrates into the concrete depends on the dye-to-solvent ratio. Dyes will not hide imperfections in the concrete; they are meant to enhance the variation that the concrete already has. Acetone dyes are made to be used on polished concrete floors that have not been sealed. If your floors have been sealed, the sealant will need to be removed before the dye is applied.


Broom, vacuum, or mop
Solvent or water, as per directions on the dye
Plastic bucket
Rubber gloves
Paint sprayer with acetone-safe plastic tips and seals
Sealant (polyurethane or other)


1. Thoroughly clean the floor with a broom, vacuum, or mop. Let it dry completely before moving on to the next step.

  1. Mix the dye in a plastic bucket according to the manufacturer’s directions.
  2. Wearing rubber gloves, load a paint sprayer.
  3. Spray the dye onto the floor from a distance of about two feet (60 cm), using a circular motion.
  4. The dye should penetrate the surface and be absorbed within about 1 minute. If working with a water-based dye, wipe away any excess with water and a sponge to avoid puddling on the surface.
  5. Wait 15 minutes and apply a second coat, if desired, to darken the color.
  6. Using the sprayer with a nozzle tip made for sealants, spray with a sealant. The dye dries quickly, so the floor can even be sealed the same day.
  7. Let the sealant dry for several hours before using the floor. Dyed cement floors should be cleaned like any other floor—with a mild mix of soap and water.

Most dyes are packaged in concentrated form, allowing flexibility in the end color. They can be used full strength to attain greater depth of color or diluted with water or solvents to produce paler shades or simply a light wash of color. You can also intermix different colors of dye to produce your own custom hues.

When to Use a Concrete Dye Concrete dyes can further enhance your chemical staining projects and open up a whole new set of design options. Harris says that the primary reason for using dyes is flexibility to obtain colors not possible with chemical stains. “When concrete dyes are combined with chemical staining, there are no limitations from a predetermined color palette,”
