When carrying out repair or construction work, quite often situations arise in which you have to make holes in an already finished wall. This is done in cases where it is necessary to conduct additional communications.
or during redevelopment. To do this, use a special tool with carbide drills and cutters. However, there are also situations in which you have to expand the doorway or re-create it in the wall.
For such work, a completely special tool should be used, which differs not only in its power and material for manufacturing the cutting elements, but sometimes even in the principle of operation. This is due to the fact that the design of the doorway in a brick wall or in concrete is a fairly large-scale process, and often it is necessary to deal with various solid inclusions, and in the case of panels, also with fittings. That is why it is not only difficult, but also unprofitable from an economic point of view, to make such work with conventional milling cutters and saws.
It is worth noting that a professional tool for making a doorway
It is very expensive. Therefore, only large companies or large construction crews can afford it. At the same time, there are also such masters who, acquiring a similar tool, are engaged only in making holes in concrete. Their ads can often be found in special newspapers, and the services of such specialists are often used by various construction crews, for whom it is easier to pay for doorway manufacturing services than to do it yourself.
However, if you have to do this work yourself, then you should initially make accurate measurements. Then draw directly on the wall the shape of the future door with a small margin for additional refinement. It is better then to remove a part of the wall a little more than to close up a too large gap. Then you need to drill a few holes in the wall to loosen it and prepare for the formation of the doorway.
After that, you can use tools such as a sledgehammer, hammer, chisel and puncher to make a large hole and expand it to the required size. In this case, you can use a
metal saw or other tool to remove the reinforcement or wire. Often, gas welding is used for this.
After forming the doorway, prepare it for door installation. To do this, all the end parts should be leveled and plastered. Then the walls are putty using a perforated corner so that between the inside and the door frame there is a small space of about two centimeters on each side. It is also recommended to immediately treat not only the walls, but also the joints of the opening with a primer to give it strength and improve adhesion.
After performing all of the above processes, the doorway is considered ready. In it you can immediately install various designs or fasten the necessary material.
