Everything starts with a marking. Professionals draw it in order to estimate where the first sheets of cardboard will lie. A long construction level or a spirit level is used. A suitable length of the construction level is about one and a half to two meters, it itself should have 4 marks in the inspection window: 2 on both sides of the air bubble. Such requirements to the tool allow you to guarantee the accuracy of marking measures.

The resulting line must necessarily close, i.e. end at the starting point, displacements are not allowed. In the corners of the room, marking with a building level is carried out similarly to the work with a water level. When marking the adjacent walls, the level is placed not only on the surface of the walls, but also in the corners at a distance.

Next, our craftsmen make profiles for the ceiling to be attached somewhere. There are even some rules that all renovators follow: at the points of contact of the UH with the wall, the profile should be glued with sealing tape.

The standard length of the PN — 3 meters, when fixing such long elements, the connection with the wall should occur in at least 4 places. Dowels and nails used for fixing should have a mushroom-shaped head, similar to a washer. Such fasteners create a durable and reliable connection, as they reinforce the contact of the profiles with the wall.

After that, it is required to install the frame, which, in fact, the team does. And then mount the drywall on it. Whole sheets of plasterboard (GPB) are attached perpendicular to the long guide profiles.

The joining of the sheets is carried out in the middle of the profiles. To ensure the quality of the fixing of the drywall boards to the profiles, the workers usually perform this task in pairs. Sheets are connected to the profile with self-drilling screws, and screws need to go a little deeper (recessed) in the GPB - literally 2-3 millimeters. The gap between the fasteners is approximately 25-30 cm, and from the corners of the drywall — 3-4 cm. Also, the indentation from the edge of the drywall to the place of screwing in screws must be observed — one and a half centimeters. The formation of chips on the edge of the sheet is prohibited. If this does happen, the screw is removed and a new one is screwed in next to it (3-4 cm from the place of chipping).

Now, with regard to cutting gypsum board. Most construction crews emphasize only a few, but very important principles:

The marking of gypsum board sheets should be carried out by a rule made of aluminum, pre-cleaned from dirt. If you do not have a tool, a flat rail will do.

On the sheet is drawn a marking, on which the cutting will take place.

At a depth of 2-4 millimeters on the rule (or lath) with a sharp construction knife is made an incision. The line should be flat, continuous.

The sheet of plasterboard is placed by the line of the notch to the edge of the table and with a careful but confident movement is broken. If the cut was made correctly, the drywall will break evenly.
