Yes, it can be used on bricks and mortar in interior or exterior settings. As long as it has not been previously sealed and is still porous, the sealer can soak into the material. If your unsure if it has a sealer on it, you can simply take some water and spray or sprinkle some on other surface. If it soaks in, it does not have a sealer on it and the Penetrating Concrete Sealer will take.
