Does the color match my existing grout?

With 12 available shades ranging from bright white to coffee and dark gray, most users find a suitable option for typical grout colors. For custom grout, we recommend testing on an inconspicuous spot for the perfect color match.

How long does it last in damp shower areas?

On walls and splashbacks, clean grout can be expected for several months with regular cleaning. In heavily used showers, refreshing with the pen every few months maintains a continuously fresh look.

Is it safe to use around children and pets?

Yes, the water-based, non-toxic, and low-odor formula contains no harsh bleaches or chemicals. Indoor use is safe without requiring hours of ventilation afterward.
