An adobe wall. Kelly Presnell/Arizona Daily Star 2010

Q:Β I have a 45-year-old house built with adobe bricks that originally had black mortar used in between the bricks. Over time, the mortar faded from black to almost white. I was told that I could restain the mortar to make it black again, but that I would have to brush the stain on the mortar seams. Can’t I just spray it on using a tiny spray gun?

A:Β You can put a new stain on the mortar, provided it’s in good shape, but you would have to mask every brick in order to spray on the stain, and you wouldn’t want to do that. You want to be sure that the stain doesn’t drip onto the bricks themselves. Before you proceed, you should talk to an adobe brick expert.
