When carrying out repair or construction work, situations often arise in which you have to make holes in an already finished wall. This is done in cases where additional communications are needed
or when redevelopment. To do this, use a special tool with carbide drills and cutters. However, there are situations in which it is necessary to expand the doorway or re-create it in the wall.
For such work, you should use a very special tool, which differs not only in its power and material for the manufacture of cutting elements, but sometimes even in the principle of operation. This is due to the fact that the design of a doorway in a brick wall or in concrete is a rather large-scale process, and you often have to deal with various solid inclusions, and in the case of panels, also with reinforcement. That is why it is not only difficult, but also unprofitable from an economic point of view, to carry out such work with conventional milling cutters and saws.
It is worth noting that a professional tool for making a doorway
worth a lotexpensive. Therefore, only large companies or large construction teams can afford to purchase it. At the same time, there are also such craftsmen who, acquiring such a tool, are only engaged 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 teams, for which it is easier to pay for the services of making a doorway than to do it yourself.
However, if you have to do such work yourself, then you should first make accurate measurements. Then draw the shape of the future door directly on the wall with a small margin for further refinement. It is better then to remove part of the wall a little more than to close up too large a gap. Then you need to drill a few holes in the wall to loosen it and prepare it to form a 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 reinforcement or wire. Often gas welding is used for this.
After forming the doorway, prepare it for the installation of doors. To do this, all end parts should be leveled and plastered. Then the walls are puttied using a perforated corner so that a small space of about two centimeters remains between the inside and the door frame.each side. It is also recommended to immediately process not only the walls, but also the joints of the opening with a primer to give it strength and improve adhesion.
After completing all of the above processes, the doorway is considered ready. You can immediately install various structures into it or attach the necessary material.
