Grout Pen White Tile Grout Paint - Waterproof, 5mm Tip, 7mL (3 Pack) | Rainbow Chalk Markers Limited

Refresh grout without harsh scrubbing

Forget heavy scrubbing—our GROUT PEN makes it possible to paint and recolor grout, giving tile lines a bright, fresh look. The water-based colorant is non-toxic, designed for interior spaces, and can be a simple part of routine refreshes in kitchens, bathrooms, and more.

Designed for unsealed grout, this marker is best tested on a small area first. The cap color guides you to the closest match from the color chart, but keep in mind the shade may vary slightly in person. When used as directed, the pen can help unify grout lines across walls, backsplashes, and floors, even where tile patterns are busy or high-contrast.

What you get and how it works

This is a 3-pack with 7mL pens that feature a narrow 5mm tip, suited for thin grout joints. Each pen delivers long-lasting color that can cover up to 150 feet of thin 2mm grout, making it a practical option for larger areas as well as smaller touch-ups.

• Brightens grout lines without aggressive scrubbing
• Suitable for bathrooms, kitchens, and other tile-surfaces like walls, counters, and backsplashes
• Non-toxic, water-based colorant designed to minimize indoor odors
• Cap color corresponds to the color chart; test a small area first for best match
• Best on unsealed grout; perform a moisture test on a hidden area to check seal status

Tips for best results

• Prime the tip by pumping with the cap on until the white tip is fully saturated, then proceed
• Light, even strokes help the color spread along each grout line and reduce tip wear
• Allow the ink to dry before cleaning nearby tiles to prevent transfer
• Store capped to preserve ink quality between uses

Real-life use scenarios include refreshing grout around a glossy subway tile backsplash, brightening shower grout that accumulates soap scum, or reviving floor grout in high-traffic entryways. The end result can feel like a subtle, refreshed surface, boosting the overall look without a full remodel.

Note: The cap color provides a close visual reference to the color chart. If you are matching an exact shade, test on a hidden area first, as lighting and tile color can affect perception.
