How can I seal my brick deck?

Question:We bought our house with a brand new, beautiful brick deck. Shortly after we moved in, grass and dirting started comming up from between the bricks, so I'm guessing the guy before us didn't bother putting anything between the dirt and the bricks, since he was selling the house and didn't have to deal with it. What can I do now to prevent grass and moss and dirt from taking over my deck? It's level and everything.

Like a brick patio?
I'd say you are probably always going to have to treat it with an herbicide. I mean, people get weeds growing up in blacktop driveways, sometimes.
You can purchase brick/stone sealer at your local DIY center: Lowe's, Home Depot, etc...
That may help initially...
