Overview

Refresh tired grout without harsh scrubbing with the Grout Pen Ivory from Rainbow Chalk Markers Limited. This compact, waterproof colorant and sealer pen is designed for easy touch-ups on tiled surfaces, delivering a brighter, cleaner look across bathrooms, kitchens, and other tile areas.

Key benefits at a glance

• Paints and recolors grout to restore a bright, clean appearance without heavy scrubbing.
• Suitable for use in bathrooms, kitchens, and any room with tile floors or walls.
• Long-lasting ink that can cover up to 150 feet of thin 2 mm grout per pen.
• Advanced, non-toxic, water-based colorant that helps disguise grubby grout stains.
• Color chart guides shade selection; cap color indicates the pen color, but a small test area is advised.
• Designed for unsealed grout; if water beads instead of absorbing, grout may be sealed and not bond.

How to get the best results

• Use on unsealed grout only; perform a quick water test to check porosity before applying.
• Prime the dry tip before first use by pumping with the cap on to saturate (about 30+ pumps).
• Apply in thin, even strokes along the grout lines, then allow to dry and inspect color and coverage.
• Be mindful that the tip is cotton; avoid pressing too hard to prevent tip wear. Replacement tips are available from the seller.
• Keep the cap on when shaking or storing to prevent tip detachment; the tip is removable but not required to shake.
• Note that the cap color reflects the pen’s color, not an exact shade—test area first for best match.

Tips for maintenance and durability

Extra tips are available for ongoing projects, and the 7 mL pen is optimized for both quick touch-ups and larger grout-refresh jobs. Plan for reapplication on high-traffic areas and test the finish in a inconspicuous spot before broad use.
