Product Information

Full details

This Rainbow Chalk Grout Pen in Grey is ideal for homeowners and DIY enthusiasts looking to refresh stained grout lines between tiles. Its key benefit is restoring grout to a clean, like-new appearance while also preventing future mould growth with an anti-bacterial formulation. A potential caveat is its 5mm bullet nib, which may require careful application for very fine grout lines.

Can I use this on coloured grout?

How do I clean up accidental marks on tiles?

How long does the colour last?

Troubleshooting

Ink flow is inconsistent or not starting.

Shake the pen thoroughly. Press the nib firmly on a test surface until ink begins to flow. Ensure the cap was securely on when not in use.

Ink is bleeding onto tiles.

Apply more carefully, using a steady hand. Clean any excess ink from tile surfaces immediately with a damp cloth before it dries. Ensure the grout line is not overfilled.

Grout colour coverage is patchy.

Apply a second coat after the first coat has dried completely. Ensure the pen is adequately shaken and the nib is primed.

Pen seems to be drying out quickly.

Make sure the cap is firmly sealed after each use. Store horizontally to ensure the nib remains saturated.
