Can You Get a Black Grout Pen? A Practical Guide
Discover whether you can get a black grout pen, how these pens work, types available, application steps, pros and cons, and effective alternatives for refreshing grout color in tiled spaces.
Yes, you can get a black grout pen. These pens come in pigment- or epoxy-based formulas designed for grout lines and are available at hardware stores, home centers, and online. They color the grout to hide stains or refresh dark tones. For best results, choose a grout-specific pen, test on a hidden area, apply evenly, and seal after curing.
What a Black Grout Pen Is and How It Works
According to Grout Maintenance, a black grout pen is a handy tool for homeowners who want to refresh the look of tile grout without a full regrout. These pens come in pigment-based or epoxy-based formulas that deposit color along grout lines, either staining the surface or embedding color into the grout matrix. For many spaces—kitchens, bathrooms, and showers—a black whiteboard-like finish can dramatically reduce the appearance of stains and discoloration. The ease of use makes it a popular DIY option, especially for smaller areas or lines with stubborn dirt buildup. Always test a small, inconspicuous area first to confirm color match and ensure that the formula adheres to your grout type. Remember that color can interact with existing sealants, tile glaze, or cleaning residues, so a careful test is a prudent first step.

Comparison of black grout pen characteristics
| Aspect | Pen Type | Durability/Effect |
|---|---|---|
| Pigment-based | Easier to apply, quick color payoff | Moderate durability; may fade with heavy cleaning or moisture when not sealed |
| Epoxy-based | Longer-lasting color, more wear resistance | Higher durability but trickier to apply and remove if needed |
| Application time | Per grout line | Typically 5–15 minutes per 10 feet of grout in moderate-sized jobs |
| Maintenance | Seal for longevity | Sealing after curing extends color life |
Got Questions?
Can a black grout pen permanently change grout color?
Most grout pens offer semi-permanent color that can wear away with cleaning or abrasion. For lasting results, you may need reapplication over time or consider regrouting or epoxy stains in high-traffic areas.
Most pens aren’t truly permanent; seal and reapply as needed.
Will a black grout pen work on all grout types (cementitious vs epoxy)?
Pen formulas usually target cementitious grout and may not adhere well to epoxy grout. Always check the product specs and perform a small test area before a full job.
Check the label and test first.
Is cleaning beforehand necessary before applying the pen?
Yes. Thoroughly clean the grout to remove soap scum, dirt, and mold residues. Let it dry completely before applying the pen to improve adhesion.
Clean and dry first for best results.
Can I use a Sharpie or other non-grout marker?
Non-grout-specific markers can smear, rub off, or stain adjacent tiles. Use a dedicated grout pen designed for grout lines for predictable results.
Avoid non-grout markers.
How long should I wait before sealing after application?
Follow the product’s instructions, but most pens require at least 24–48 hours before sealing or cleaning. Full cure can take up to 72 hours depending on the formula.
Let it cure as directed before sealing.
“Black grout pens are a practical quick fix for mild staining and color refresh, but durability depends on surface prep and sealing.”
The Essentials
- Test a hidden area before full application
- Choose a grout-specific pen rather than a general marker
- Seal after curing to maximize longevity
- Evaluate area type to decide between pigment vs epoxy pens
