The longevity of the colour depends on factors such as foot traffic, cleaning methods, and exposure to moisture. The waterproof and anti-mould formula helps to extend its durability.

The formula itself is waterproof and contains anti-mould properties, acting as a protective layer. No additional sealant is typically required after application.

While not specifically recommended, attempting to mix colours is not advised as it may affect the ink's properties and consistency.

If you make a mistake, you can attempt to wipe away the excess ink immediately with a damp cloth before it dries. Once dry, it may be more challenging to remove without affecting the tile surface.
