Drywall is aan excellent modern finishing material, with which you can not only get a perfectly flat surface, but also the opportunity to make beautiful arches, transitions and niches.

Drywall, as a building material, has a number of positive properties and qualities that are own speaking, and make it widely used.

Before deciding how to mount drywall to the wall, you need to determine its structure and geometric parameters. If the wall has protrusions and niches that will not be used, then it is better to lay them with a brick, the cracks in the walls should be expanded and covered with a reinforcing mixture. In general, it is necessary to prepare the surface. Further, before fixing gypsum cardboard to the wall without a profile or with a profile, it is necessary to conduct antiseptic preparation of the base. This will prevent or stop the existence of fungus and mold.

Having dealt with the base, we will consider the ways of fixing the drywall to the wall:

Fastening the drywall to the profile. This method is used where there are a large number of irregularities and deviations on the wall. They are compensated by means of guides, which can be both wooden and metal. But fixing the profile to the wall may be required not only to compensate for unevenness. Under it, you can freely conduct all kinds of communications, make ventilation ducts and lay additional insulation.

Fastening of plasterboard to a wall without a profile. This method is used where it is necessary to preserve the space of the room, and the final one, the walls should be as flat as possible.

To start fixing the profile under gypsum board, you must select the profile itself. It is chosen based on the future load on the wall and the strength expected from it. If it is in the future will hang a kitchen or other furniture, you should use a thicker profile, and its fastening to produce more often.

In general, the profile is a rigid galvanized strip, which was obtained by bending on a press made of sheet galvanized metal. Due to this, the necessary rigidity and strength is obtained. The profile used for the construction of the lath under the GKL profile can be of two types: the

  1. CD is the main element that imparts stiffness to the structure and attachment of the hinged elements of furniture is carried out to it. It is mounted in the form of a crate, fastening at the intersections. To it and fastening of plasterboard is carried out.
  2. The UD profile is a narrower U-shaped bar without additional stiffeners. Used to fix the crate and to fix the drywall to the wall along the perimeter, to the ceiling and the floor. If necessary, a CD is inserted into it. Therefore, its size must be selected in accordance with the height of the CD.

To fix the plasterboard to the wall with you it is necessary to have a corresponding set of tools: a perforator, a screwdriver, etc. If the wall is wooden, then you can fasten the structure with ties or anchors, for this you will also need a drill.

Isolation

Insulation

Fastening of profiles for gypsum cardboard to the wall is carried out with the help of dowels. They are also chosen based on the load on the wall and its structure. If the wall is made of blocks ASG, then their length should be large enough to penetrate deep into the structure. Sometimes even the best option will be the use of anchors. This will allow the wall of plasterboard not only to become stiff, but not deformed with time under the influence of outside forces. To properly mount the profile under gypsum board it is necessary to maintain the fastener interval no more than 50 cm vertically.

Fastening plasterboard to the wall using a profile requires compliance with a certain technology:

There should be both vertical and horizontal structural elements. In doing so, they are fastened together by additional elements or methods. There are two types of connection of CD-profiles:

  1. T-shaped. It is used in places of transverse joints of gypsum boards.
  2. Cross-shaped connection with crabs. These anchorages for the profile are a metal element with four sides and many additional taps - petals for bending around the CD profile. The profile is joined together by means of self-tapping screws for metal or rivets, but it is better to use self-tapping screws to give more rigidity.

Fastening of a metal profile

First of all it is necessary to put a marking on the wall for the future frame. This can be done with a cord and a level. To fix the drywall to the wall correctly, it is necessary to withstand the vertical position of the vertical sections, and the horizontal ones are strictly perpendicular to them. For this it is necessary: ​​

  • With the help of a level, place the fixing points of the end elements - UD, retreat a small distance from its center and pull the cord.
  • Next, vertical racks are mounted on the tags and laces. This profile for fixing gypsum cardboard should be placed in a structure with a step of no more than 60 cm. The UD profile is attached to walls, ceiling and floor by screws or brackets with a step of not more than 40 cm.

It is important to remember, at this stage, if it is planned to mount on a drywall wallheavy furniture or appliances, then in the CD-profile it is necessary to put a wooden bar. And it is already boldly possible to twist large screws and brackets.

At this stage it is necessary to make marking and wiring of all communication, and in sheets of drywall cut openings for ventilation inputs, sockets and switches. Next, you need to decide what to fix the drywall to the profile. But the task is not so difficult, because the fasteners are made with screws with conical hats and fine threads. This allows them to calmly sink 2-3 mm into the sheet structure, without creating unevenness in the plane. The size is chosen based on the thickness of the sheet, usually 4-3 cm is enough. To properly fix the drywall to the wall, it is necessary to maintain the distance between the screws no more than 30 cm.

Also, as a fastener for gypsum board, there may be screws or screws. But preliminary it will be required to drill holes with a drill of a smaller diameter in the profile for the screws. The fixing for gypsum board is chosen based on the material of the supporting structure and the thickness of the sheet.

All joints of plasterboard sheets should be carried out on a wide CD-profile. At the same time, if the sheets are selected with the factory chamfer, the seams can be sealed with a reinforcing mesh and putty. Also it is necessary to remember that fastening of sheets occurred strictly in vertical and horizontal position. This will greatly facilitate the process of work in the future.

Technique for mounting drywall to a wall without a profile

If it is necessary to save the maximum space, then fastening sheets without a profile is used. For this, special glue and dowels can be used. Before you figure out how to fix a drywall to a wall without a profile, you need to measure the wall and find out where the greatest deviation is. On that place it will be necessary to lay the same plasterboard and more glue. Before applying the adhesive, both surfaces must be primed first.

It is important to remember that when gluing sheets from below, it is necessary to retreat a distance of at least 5 mm. This is necessary for the possibility of its thermal expansion due to changes in humidity. Also, to attach a drywall to a wall without a profile as high as possible, it must be supported by any stand for the time of drying.

Cutting plasterboard with your own hands, photo

Having figured out how to fix the plasterboard to the wall, it is necessary to proceed directly to its installation. But in the process of work now and then have to cut off from him pieces of a variety of lengths and shapes. To do this, you can use the following tool:

Plasterboard cut

Plasterboard cut

  • Electric jigsaw. Used for curved cutouts if necessary.
  • Mounting knife. The main tool for cutting.
  • Saw the saw. Used to cut large rectilinear elements.

For a smooth cutting of a piece, you need to use a metal ruler. Firmly pressing it to the surface and strongly pressing on the mounting knife, the top layer of cardboard is cut along with the gypsum composition. Next, the cut piece is gently bent backwards and the paper is cut from the second side with a knife. After cutting out the necessary piece, the drywall is fixed to the wall without a profile or with it, as was previously planned.

Chamfering on the

Drywall. Many wall elements require perfectly smooth angles and surfaces. It is often required that the corner elements ideally converge. To do this, you need to remove the chamfer from the sheet. This can be done with a mounting knife. It should be noted the distance from the edge of the sheet of 10 mm and under the metal ruler or level carefully cut the corner at an angle of 450.

We make a cut in the plasterboard

Drywall is a three-layer sheet material that can be easily processed by any tool. In order to cut in it a round hole for sockets and switches use mills and nozzles on a drill. For cutting large curved holes, use an electric jigsaw, straight square holes - a hacksaw with a small tooth. To do this, do longitudinal using a saw blade, then the remaining side is cut with a mounting knife and the sheet is broken. On the other hand, the second layer of paper is cut.

Processing of joints of plasterboard sheets, corners of internal and external

Often, in order to fix plasterboard to the profile in high-quality in hard-to-reach places, it is necessary to make corners and joints fit. To do this, you can use a special plane for gypsum cardboard or a file on wood.

Treatment of joints on the wall of gypsum board

Processing of joints of plasterboard sheets is reduced to their spreading with putty. Ceiling sheets for this have a special thinning to the edge. It reinforces the reinforcing mesh, but it is necessary first to cover the deep seams and pits from the screws with putty or gypsum composition. He most quickly freezes, which allows you to do all the work at a time. The mesh is adhered by the same composition, and then it is covered with the finishing layer of putty. The mesh is sold at a standard width of 80-100 mm or you can cut it from a roll. For spreading seams and grooves, it is better to use a spatula with a width of 60 - 80 mm.

How to fix interior items to plasterboard? If it is necessary to fix the interior elements of a small weight to the gypsum board, for example, a lamp, a shelf or a hanger, then it is necessary to use so-called butterfly fasteners. They are dowels with plastic clips, which, when the screw is screwed open, like wings of a butterfly, securely fixed in a sheet. It can also be used other fastening in gypsum board, acting on the same principle.
