[00:04] biggest problem, which is the gypsum board issue. The gypsum board problem means that in some places I go in and gypsum board problem means that in some places I go in and find, for example, that the gypsum board is cracked or my joints are showing. The second point is the
[00:20] second point is the finishing work, I don't know how to differentiate between these materials and those materials, and I don't know those materials, and I don't know if the gypsum board is installed correctly
[00:35] or not, or anything like that. Last week, someone called me about a Last week, someone called me about a villa in Shorouk. I went and they told me to come and see how things were. I found that all the gypsum board was flat and lying on the
[00:50] was flat and lying on the floor. I found that the installer had installed it with something called a " joint." The problem with these joins is that I do n't use small screws. I've talked about this point before; I don't use a hook. This hook is like...
[01:07] Where does the Fisher steel system attach?  It's fixed to the ceiling and called a " tack." This fixing is completely different from the other fixing method for gypsum board. There are two ways: either with a "tack" (which is an
[01:20] iron nail) or with a " hook." A "hook" is a closed nail, but it's large and can bear weights. But which is better? The "tack" method. This is a method. This is a nail with an iron anchor that goes into the ceiling.
[01:35] Its load-bearing capacity is greater than that of a "hook." Okay, so how do I know that, for example, the installer hasn't cheated me on the materials or the
[01:49] installation system? First, I should have seen their work before and talk to them about their installation method and the stages of their gypsum board installation. Have them photograph each stage, for example, when they're making
[02:01] gypsum board installation. Have them photograph each stage, for example, when they're making the frame, or take delivery of the frame. This way, I avoid the possibility of them cheating me on the issue of the bracket or the
[02:13] cheating me on the issue of the bracket or the hook. If I use a hook, I reduce the distances. I work on every  60 cm length and 60 cm width. No, in the angles, work every 50 cm, excluding the tie beams, of course. Okay, so
[02:25] when I look at the ceiling, for example, the gypsum board ceiling, there's a small line that's a gypsum board ceiling, there's a small line that's a crack. That's where the problem lies in the repair. The repair means that any joint in the gypsum board must be treated with fiberglass, which is the kind of mesh covered with
[02:41] mesh. This is done when the gypsum board is handed over, and then it's plastered over. Otherwise, if there's no plastered over. Otherwise, if there's no mesh or fiberglass, any joint without any mesh or fiberglass will never hold
[02:53] up properly. Over time, it will inevitably crack. And I have another crack. And I have another point: the light fixture. If I'm going to install a light box, for example, I have a corner bracket for the light fixture, and I install a metal angle bracket or
[03:10] its alternative, which is metal. You can't leave the connection between the base and the leave the connection between the base and the small mirror without anything to adjust it and ensure straightness. If I'm using a flat, raised ceiling, I install something for it.  It's called A&B, which
[03:25] is an inverted angle bracket that's installed to thicken the gypsum board. This is about gypsum board and the problems I board. This is about gypsum board and the problems I always encounter at work.
