Can Black Galaxy granite be re-dyed or darkened?

Q. Can Black Galaxy granite be re-dyed or darkened? 

A. Technically, yes, you could attempt to re-dye or darken Black Galaxy granite, but it would not be advisable. Granite is a very dense natural stone, which means it doesn’t absorb liquids, including dyes, very easily. That makes achieving an even, consistent color change difficult. Dyeing stone is not a straightforward process and often comes with risks, such as blotchiness, streaks, or unnatural-looking surfaces.

Some manufacturers offer specialized stone dyes that can sometimes be used to enhance or darken the stone’s appearance. If you go this route, the granite must be properly prepared, the dye carefully applied, and then sealed with a high-quality stone sealer once the dye has fully cured. The sealer is critical because it protects the color enhancement and helps prevent uneven fading, caused over time by sunlight, cleaning chemicals, or wear. So the sealer would create additional potential for undesirable results were you to go the DIY route.

Because of these challenges, we recommend leaving this type of work to a trained and experienced contractor. A stone and tile restoration PRO will know how to properly test, apply, and finish the dye to give you the best possible outcome.
