My name is Giulliano Prieto, a general engineering contractor with Prieto Engineering in Los Angeles, California, and today I will show you how to clean brick mortar. Your materials needed are a chisel, a hammer, a bucket of water and a tile sponge. During the construction process, a little bit of mortar has fallen to the ground. Now, I will show you how to remove this mortar from the ground in a few steps. The first step is to take a hammer and lightly tap it on top to see if it will just break up easily. For areas that are a little bit more difficult, without pounding a hammer on to the surface, take a chisel and place it directly on top of it and tap it lightly. Once you have broken up the pieces with either a hammer or a chisel, or both, you are now ready to pick up the pieces. Next, take your sponge, get it nice and wet and begin removing the residue. If it hasn't been too long, the residue should be able to be picked up very quickly. Typically, if grout has stayed on to the floor for longer than about a day or so, the concrete is going to get hard and probably bind to the floor. Now, in order to remove that, what you can do is do one part muriatic acid to four parts water, mix it in a mixing bucket, take your sponge, wipe it off and then take some clean water and wipe away. That should be able to take care of it. My name is Giulliano Prieto with Prieto Engineering, and it's been my pleasure to show you how to clean brick mortar.
