Rainbow Chalk Markers Grout Pen Light Grey – Waterproof Grout Paint, 3-Pack, 5mm Tip

Refresh grout lines with ease

Keep tile grout looking fresh without the back-breaking scrubbing. The Grout Pen Light Grey uses a durable, non-toxic, water-based colorant to recolor dull grout and mask stubborn stains. The result is a brighter, more uniform appearance that complements any tile, creating a clean, inviting look in minutes rather than hours.

Designed for everyday spaces, this pen excels in bathrooms, kitchens, showers, backsplashes, and even entryways. The narrow 5mm tip offers precision for tight seams on walls, counters, and floors, so you can target grout lines without coating adjacent tiles.

Strong points at a glance

• Long-lasting color: each pen can cover up to 150 feet of thin 2mm grout, making it practical for both small touch-ups and larger refreshes.
• Advanced formula: a non-toxic, water-based colorant that visually renews grout by masking grime and stains.
• Color guidance: the cap color indicates the shade, with a quick test area recommended to confirm the match before full use.
• Usage notes: best results occur on unsealed grout; if grout is sealed, adhesion may be reduced and a test is advised.

How to get the best results

Begin by priming the tip—pump with the cap on until saturated. Shake is not required, but cap-on shaking is recommended if needed. Pressing too hard can wear the cotton tip; replace tips if needed. Allow for light coats and dry between applications for an even finish.

Practical benefits for daily life

• Save time by refreshing grout instead of scrubbing, especially in busy kitchens and baths.
• Achieve a modern, uniform grout look that elevates tile aesthetics across rooms.
• Rely on a straightforward color reference and simple steps for ongoing grout maintenance.

What’s in the package

Three light grey grout markers with a 7 mL ink volume each provide enough coverage for multiple areas or a complete home refresh.
