Step 12: Rest, then the actual pointing.
place the dowel or handle on the mortar. tap and move, tap and move, tap and move... do the vrticals as well.
If it gets dirty, the mortar is still too wet and needs to wait another 15 minutes or so.
The pointing looks pretty, creates a durable surface, and also helps shed water if it gets wet.
If your brick has an existing pattern (raised, etc) you may need to find special tools and instructions. This is in my basement, so I'm going for pretty + functional with minimal fuss.
