Setup, Compatibility & Care
This marker is designed exclusively for cementitious grout lines. Do not attempt to use this product on silicone caulk or sealant, as the ink will not adhere and will likely bead up and wipe away. For maintenance, keep the cap tightly closed when not in use to prevent the ink from drying out. Store the marker horizontally to maintain an even ink distribution within the barrel. If the tip becomes frayed over time, you can often gently remove and flip it if the marker design allows, or simply replace the marker once the ink supply is exhausted.
