Rainbow Chalk Markers Grout Pen White – Narrow 5mm, 2-Pack Tile Grout Colorant & Sealer (7mL)

Refresh grout without bleach

Meet the Rainbow Chalk Markers Grout Pen White—an easy, bleach-free way to refresh grout with a non-toxic, water-based colorant. This pen is designed to cling to unsealed grout, helping color inconsistencies fade into a brighter, more uniform tile line. The result can make tiled surfaces look cleaner and more polished, especially in high-traffic rooms like kitchens and bathrooms.

Key benefits at a glance

• Non-toxic, water-based colorant formulated for unsealed grout
• Each pen covers up to about 150 feet of 2mm grout
• Narrow 5mm tip for precise, tight-line application
• 2-pack with extra tips included (7mL per pen)
• Cap color helps you visually match and pick colors quickly

How to use for best results

Preparation matters. Test a small area to confirm the grout is unsealed; if water absorbs within a minute, you’re good to proceed. Shake with the cap on, then prime the dry tip by pumping until fully saturated. Apply in light, even strokes along the grout line, and wipe away excess to avoid smudges. Allow the ink to dry before foot traffic or cleaning.

• Apply in a well-lit area to assess color matching
• Work in small sections to prevent smudges or streaks
• Only use on unsealed grout; sealed grout may not bond well

Where it shines

Perfect for bathrooms, kitchens, backsplashes, and tile floors or ceilings where a refreshed grout look matters. The slim 5mm tip makes it easier to color narrow lines and edges with control.
