How to use One Coat Grout Pen

Before you start

Clean your grout to get rid of any mould or stains.


  1. Shake the pen until you hear it rattle. The nibs are reversible so you can choose which end you want to use. The round end covers larger areas and the flat end will give you neater lines.
  2. Hold the nib down on some paper until white paint starts to come out.
  3. Use the grout pen just like a normal pen; be carefuly not to press down too hard as the paint will come out fast and overflow and you may quickly wear out the nib.
  4. Use it on vertical grout lines first. If you get any on your tiles, use a damp cloth to remove it.
  5. If you’re grouting a large area, you might need to use the spare nib. Just take the old nib out and slot the new nib into the barrel.
  6. Leave it to dry for 24 hours.

That’s it, job done!



Once your grout is completely dry, you can clean it and your tiles just like normal.
