Step 1: Clean the concrete surface.

Use an organic concrete cleaner & degreaser solution to thoroughly scrub and rinse all residues from the surface. Allow the floor to dry.

Step 2: Seal the concrete surface.

Apply one coat of acrylic concrete sealer prior to applying the dye. This is especially important for porous and outdoor concrete.

Step 3: Mix the concrete dye.

Follow the instructions on the dye packaging to properly mix the powder. Remember to wear goggles and gloves while working with the dye. If you need additional guidance on how to use concrete dye, you can check out our blog “How To Use Concrete Dye” for more information.

Step 4: Apply the concrete dye.

Shake the mixture in the sprayer frequently to ensure an even, consistent color. Spray the dye going right to left, then north to south. Avoid applying the dye too thick, as it will dry almost instantly. Generally, three to four coats should be sufficient, but you can add more for a darker color. Be sure to mop up any areas where the dye pools up.

Step 5: Wipe off any residue.

Allow the dye to dry thoroughly, then use a dry buffer, soft cloth, or dust mop to remove any excess colorant or residue.

Step 6: Seal the dyed concrete.

Apply the same acrylic concrete sealer that you used in Step 2, using a pump up sprayer. Use caution when applying solvent-based sealers, especially in indoor areas. Wear a mask and ensure the area is well ventilated. If the space is poorly ventilated, such as a basement, use a water-based sealer instead.

If you’re dealing with old acid stained concrete, you may need to strip the existing sealer before starting the staining process again.
