Product Information
Full details
The Rainbow Chalk Grout Pen in Grey is designed for homeowners and DIY enthusiasts looking to refresh stained or discolored tile grout lines without the need for intensive re-grouting. This water-based ink formula effectively covers everyday dirt and mould build-up, restoring a clean appearance while incorporating an anti-bacterial agent to help prevent future staining. While it is an excellent tool for cosmetic restoration, users should note that it is intended for surface application and will not structurally repair crumbling or damaged grout.

FAQs
Can I use this on shower floor tiles?
Yes, but ensure the area is allowed to dry completely before and after application to ensure the ink sets correctly.
Does this product repair cracked grout?
No, this is a cosmetic restorer only and will not fill or repair structural cracks in the grout.
How long does the effect last?
Longevity depends on foot traffic and cleaning habits, but the anti-bacterial formulation helps maintain the look significantly longer than untreated grout.
Is the ink waterproof?
Once fully cured, the water-based formula is resistant to everyday moisture, though it should not be submerged in water during the curing period.
Can I use this on different tile types?
The pen is compatible with most standard cement-based grout lines used with ceramic or porcelain tiles.
Troubleshooting
Ink is not flowing from the tip
Shake the pen vigorously and press the nib down on a firm surface repeatedly to stimulate ink flow.
The ink is wiping away during application
Ensure the grout line is completely free of soap residue, grease, and moisture before applying.
Pros and Cons

Setup, Compatibility & Care
Before initial use, shake the pen well to ensure the pigment is properly mixed. Press the tip onto a scrap piece of paper or cardboard to prime the nib until the ink begins to flow. Once finished, ensure the cap is snapped on tightly to prevent the nib from drying out. Store the pen in a cool, dry place away from direct sunlight. While the ink is designed for durability, avoid using harsh abrasive cleaners directly on the treated lines to prolong the lifespan of the restoration.
