You can use a bristle brush or a foam brush, but many people find using a toothbrush works very well (however it may flick grout paint around if you are not careful).

Before painting, you must clean the grout very well.

When painting your grout, you will probably want to put small amounts of the grout paint in a small shallow dish, perhaps an old plastic food container.
Apply the grout paint in long strokes.
Do not let the paint pool on the grout.
You will probably need 2 coats or more depending on the difference in your old and new grout colors.
Make sure to let the first coat dry for at least 30 minutes before applying the second coat.
After the grout paint is dry, clean the tiles using the manufacturer's recommendations.
