FAQs

How long does the coverage last?

The pen covers up to 60 meters of grout area. The longevity of the finish depends on the usage and cleaning of the tiled area.

Is this product safe for use in bathrooms?

Yes, the grout pen is water-based, non-toxic, and anti-bacterial/anti-fungal, making it safe for use in enclosed areas like bathrooms.

Can I use this on coloured grout?

This specific product is for 'Grey' grout. Please ensure you select the correct colour pen for your specific grout to achieve the desired aesthetic.

How do I clean up any mistakes?

Wipe away any excess ink from tile surfaces immediately with a damp cloth while the ink is still wet.

What should I do if the ink doesn't flow?

Shake the pen vigorously with the cap on, then press the nib down onto a piece of scrap paper or cardboard to activate the ink flow. Repeat if necessary.

How long does it take to dry?

Drying times can vary, but it is recommended to allow the grout to dry completely before exposing it to moisture. Refer to the product packaging for specific drying times.

Can I paint over this if I change my mind?

While the formula is water-resistant once dry, it may be possible to cover with a suitable paint or coating, though testing in an inconspicuous area is advised.

Troubleshooting

Pen is not dispensing ink

Ensure the pen is shaken well. Press the nib firmly onto a test surface several times to activate the valve and allow the ink to flow. Check that the nib is not blocked.

Ink is bleeding onto tiles

Wipe away excess ink from tile surfaces immediately with a damp cloth. Ensure you are applying the pen directly and neatly into the grout line. For very porous tiles, consider applying a tile sealer to the tile surface before application.

Uneven coverage

Apply with consistent pressure and speed. Multiple thin coats may be more effective than one thick coat. Ensure the nib is clean and not clogged.

Pen has dried out

Ensure the cap is securely fastened after each use. If the nib has dried slightly, try moistening it gently with a damp cloth and reactivating by pressing on a test surface.
