Tips

For best results, clean the grout lines thoroughly and allow them to dry completely before application. Shake the pen well, press the nib gently to saturate it, and apply in a smooth, even motion. Avoid walking on treated floor grout for at least 24 hours to ensure full cure. Store the pen horizontally with the cap tightly closed to prevent the nib from drying out.
