Refresh grout quickly with the Brown Grout Pen

Give tired grout lines a renewed, bright appearance without harsh scrubbing. The Grout Pen Brown from Rainbow Chalk Markers Limited combines color and sealant in a water based formula, delivering a smoother, more uniform look on ceramic tiles, backsplashes, and shower surrounds.

Key benefits at a glance

• Waterproof colorant and sealer in one, for a durable grout finish.
• Narrow 5 mm tip enables precise lines along narrow grout lanes.
• Two pens in brown with extra tips for extended projects and ongoing touch ups.
• Long lasting ink that can cover up to 150 feet of 2 mm grout, reducing maintenance time.

How it works and what to know before you start

• Non toxic, water based formula colors and protects grout without harsh solvents.
• Cap color provides a quick reference; shade may vary from the chip, so test a small area first.
• Use on unsealed grout only; if grout does not absorb water within a minute, it may be sealed.

Usage tips for best results

• Prime the tip before first use by pumping with the cap on until saturated; the tip starts dry.
• Avoid pressing hard, as the cotton tip can wear down; contact the seller for replacement tips if needed.
• Shake with the cap on; store cap on during use to keep the ink ready, and gently apply for even coverage.
• Let the color dry between coats and perform a small test area to check color match.

With proper preparation, you can achieve a refreshed grout line that looks uniform and renewed, while enjoying an easy maintenance routine and a color renewal option that stays within tile lines.
