Sheet plasterboard allows you to performalignment of walls of almost any type. The material is strong enough, cutting and installation is quite simple. With its help, you can not only hide the unevenness of the walls, but also build an interior partition or reduce the doorway. Before you align the walls with plasterboard, it is recommended to familiarize yourself with the order of the work.
Plasterboard sheets have a fairly flexible structure, which makes them ideal for leveling walls. You can level walls in one of two ways:
- fasten the sheets to the previously constructed frame;
- glue the material directly to the wall.
The frame method is more reliable and simpler. However, after leveling in this way, the area of the room is significantly reduced, since the thickness of the lining is at least 4 cm.
Preparatory work
Before leveling the wall, it is necessary to carefullyclean off old finishing materials. The work is carried out in stages. First of all, the walls need to be prepared for further finishing. First, all old finishing materials are removed, the surface is cleared to the base. Old laths and plaster are easy to remove, as this coating often comes off the walls. Such cleaning will not only prepare the work surface for the next stage, but will also free up a few centimeters near the wall. Next, it is recommended to prime the walls. Antiseptic treatment is mandatory. This is especially important for external walls. Markings are applied to the surface of the floor and ceiling. Straight lines should mark the boundaries of the future wall along which the drywall will be placed. Return to contents</a>
Assembling the frame
Plasterboard frame diagram.The framework for mounting plasterboard sheets is assembled from galvanized profiles. This will require profiles of various shapes. UD profiles are attached to the floor, ceiling and adjacent walls. They rest on the surface with the central part. Dowels are used for fastening. Jumpers are placed in the formed frame. For this, CD profiles are installed vertically and fastened to the wall with their edges. The wide, even edge should be directed into the room. Special screws with a drill end are used to fasten the profiles. Such fasteners are specially designed to make holes in galvanized profiles for themselves. The first element of the frame is placed directly at one of the walls on the side. The subsequent ones are every 60 cm. This distance should be between the central lines of the profiles. On the second wall, the first profile is also fastened tightly, even if the distance between the profiles is less than 60 cm. Special perforated hangers are used for maximum reliability of the structure. They are provided with special stiffening ribs. The pieces of galvanized steel are bent in the shape of the letter "П". Their middle is attached to the wall under the vertical element. The side parts are screwed to the profiles. At this stage, it is very important to choose the correct level of fastening. If the height of the ceilings exceeds the length of the plasterboard sheets, then strips of material will need to be added at the top or bottom. To install these additional elements, it is necessary to install lintels at a height of 250 cm. Lintels are made from CD profile. Return to contents</a>
Installation of plasterboard
Scheme of leveling walls using plasterboard.To fix the plasterboard, use 35 mm long black hot iron screws. The fasteners are screwed in with a screwdriver. It makes it easier to sink the screw heads into the surface of the profile flush. The distance between the screws should be 10-15 cm. They are located in the center and along the perimeter. The central line should be marked on the sheet to make the process easier. If the whole sheet does not fit in some areas, you can cut out several pieces of the required size. For this, you need a construction knife. A cut is made along the sheet, and it is broken along the created line. A second cut is made on the reverse side. Now you know how to properly align the walls with plasterboard. After completing this work, all that remains is to apply the finishing material. Return to the table of contents</a>
Finishing of walls
It is enough to seal the seams between the plasterboardseasily thanks to the strips provided at the bottom of each sheet. This will require a self-adhesive mesh, onto which a base layer of putty is applied. Further finishing depends on the features of the chosen design method. Under tiles or other thick material that is not translucent, a starting layer of putty will be enough. For materials that emphasize surface imperfections more, a finishing layer of putty will be required. Thus, leveling walls with plasterboard is quite simple if you follow the steps of this process. The so-called dry leveling is not recommended for tight spaces. Drywall can be used not only to level walls, but also to reduce doorways or build partitions.</ ul>
