Key specifications

• Tip: replaceable fine nib for precise application
• Application: designed for grout joints between tiles

How to use

Ensure the grout area is clean, dry and free of loose debris or soap residue before application. Shake the marker gently if recommended by the manufacturer, then test on a hidden area or spare tile to check colour match. Apply the marker along the grout line with steady, even pressure and allow the treated area to dry fully. Replace the tip when it becomes worn to restore precise coverage. For larger or structural grout damage, prepare the surface and use appropriate repair products prior to colour retouching.

Usage recommendations

For best results, clean grout with a neutral cleaner and allow full drying before using the marker. Use in a well-ventilated area and store the marker horizontally or capped to prevent tip drying. Avoid use on freshly grouted joints until curing is complete.
