Rainbow Chalk Markers Limited Grout Pen Brown – Waterproof Tile Grout Colorant & Sealer (2 Pack, 7mL)

Refresh grout with precision and ease

Rainbow Chalk Markers Limited presents the Grout Pen Brown, a waterproof tile grout colorant and sealer designed to revitalize tiled spaces without harsh scrubbing. The narrow 5mm tip enables controlled lines along grout joints, delivering a refreshed, uniform look that stands up to daily wear.

Why this grout pen fits your needs

• Long-lasting coverage: each pen can cover up to about 150 feet of thin 2mm grout, making it suitable for bathrooms, kitchens, entryways, and more.
• Advanced formula: non-toxic, water-based colorant helps restore the grout color while staying user-friendly for DIY projects.
• Color accuracy: use the color chart for the best match; the cap color indicates the shade, but a small test area is advised before broader use.

Tips for best results

• Unsealed grout only: the pen may not bond to sealed grout. Test a small patch—if water beads, the grout is likely sealed.
• Prep and priming: tips may ship dry; to activate quickly, prime by pumping the tip with the cap on until saturated. Shake only with the cap on to avoid leaks.
• Care for the tip: the cotton tip may wear with heavy use; contact the seller for replacement tips if needed, and handle gently for longevity.
• Dry tip, ready to color: new pens ship with a dry tip; priming ensures smooth color transfer from the start.

Real-world uses and practical benefits

Ideal for renewing grout in bathrooms, kitchens, or any tiled area where a crisp grout line improves the overall look. The combination of colorant and sealer helps create a clean, renewed appearance without a full regrout. Although not a guaranteed result, many users report a noticeably brighter grout and a refreshed tile scene with minimal effort.
