Setup, Compatibility & Care
Preparation: Clean the grout lines thoroughly to remove soap scum, mildew, and grime. The surface must be bone-dry before application.
Application: Shake the pen vigorously with the cap on. Remove the cap and press the tip onto a piece of scrap paper or a paper towel to prime the flow of ink. Apply smoothly along the grout line.
Care and Maintenance:
- Do not use on silicone caulk or flexible sealants as the ink will not bond properly.
- Allow the ink to dry completely (at least several hours) before getting the area wet.
- Recap the pen tightly after each use to prevent the tip from drying out.
- Keep in a cool, dry place away from direct sunlight.
