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

Refresh and Protect Your Grout

Meet GROUT PEN by Rainbow Chalk Markers Limited, a waterproof tile colorant and sealer that lets you recolor grout without endless scrubbing. The Winter Grey shade brings a cool, contemporary feel to your tiles, while the non-toxic, water-based formula keeps maintenance simple and approachable for DIY projects.

In everyday spaces like bathrooms and kitchens, grout can look worn, dirty, or discolored. This pen lets you brush in color to rejuvenate grout lines, delivering a brighter, cleaner look with minimal effort. The slender 5 mm tip is designed for precise work along joints and around tile edges, while the 7 mL capacity provides ample coverage for small to mid-size rooms.

What makes it work for you

• Long-lasting ink that covers up to 150 feet of thin 2 mm grout, reducing frequent touch-ups.
• Advanced non-toxic, water-based colorant that blends with existing grout for a refreshed appearance.
• Color chart reference helps you pick the closest match; the cap hints at the shade, though testing a small area first is advised.

How to use and care

• Apply on unsealed grout only; if you’re unsure, test a small area before full application.
• Prime the tip before first use by pumping with the cap on until the tip is fully saturated.
• Avoid pressing too hard to prevent tip wear; replacements tips are available from the seller if needed.
• Shake is generally unnecessary; if you do shake, keep the cap on to avoid tip detachment.

Two-pack packaging with extra tips ensures you can tackle multiple grout lines or features across rooms, making it a practical option for ongoing maintenance and refresh projects.
