Installing drywall is a processplating surface gypsum boards. This is the most economical and fastest way to hide the existing irregularities in the substrate. Decorating the walls with the use of this material is preliminary work prior to application of plaster, paint or wallpaper pasting walls. In addition to the alignment, drywall installation allows you to insulate and soundproof room.

List of necessary tools
To carry out installation of plasterboard with their hands,It needs some special tools that are best prepared in advance. For each phase of the work is characterized by its tools to make workflow as convenient as possible.
Tools for marking:
- Level, laser level;
- Coloring lace.
In the manufacture of the frame will need:
- A hammer;
- Scissors on metal.
When working with gypsum boards should use the following tools:
- Rake the required length;
- A sharp knife;
For qualitative plugging holes by screws, joints sheets and angles should prepare the following tools:
- A container in which the mixture will get involved;
- Rollers and brushes for the primer;
- Grater with mesh or sandpaper.
Of course, when working you can not use all of the above instruments or to replace them with alternative supplies.
Options drywall mounting
Modern drywall installation technique identifies two ways:
- Frameless version (using special adhesive mixtures based on cement or gypsum);
- Wireframe option (use the frame made of metal profiles or wooden beams).
Using any method shall ensure that the main task - the smooth, reliable and durable fastening of sheets of drywall, located in the same plane.
Each of the options is reliable and durable, important to spend quality installation.
Fasten without frame
For use in mounting the framelessthe method of coating the walls should not be composed of loose material to be dry, dust-free and uncolored enamel or oil paint. When using cement-polymer or adhesive plaster base must be strong, primed and sufficiently smooth (allowed only small differences). Under the drywall, arranged in this manner, it is impossible to lay the insulation, so you have to apply foam insulation cycle. The advantages frameless method are: a beautiful sound insulation of structural noise, the minimum set of instruments used, a short distance from the front face to the ground.
Frame method - efficiently, reliably
This method involves the installation of plates alreadyready to frame, assembled from metal profiles or of timber. Frame method suitable for more complex repairs, such as creating a multilevel or complex arch ceiling structure. For similar works this kind of installation is considered the most reliable.
For the manufacture of metal framework usedprofile of galvanized steel, having a non-through incision for hardness and through-holes intended for its attachment to the surface. It should be noted that the installation according to the method is achieved by a weak sound insulation, requiring the application of additional measures to ensure it. On the downside can be attributed, and a large set of tools needed to perform the work. The frame of the metal profile is durable and humidity resistant, standardization of different elements used. The advantage of this framework becomes its application on surfaces with high roughness and it is possible to lay the insulation.
For the manufacture of the frame of wood useddry, smooth, planed timber. Undoubtedly, this type of frame is different environmentally friendly material has good sound insulation and allows to build additional insulation. After assembling the wooden frame should conduct processing special impregnation, which protects material from moisture, mildew, rot, bugs.
Marking surface for rack mounting
For high quality of repair works should be performed markup surface.
Partitioning walls carried out in the followingsequence. It is necessary to measure the distance of 5-6 cm from the corner and on the adjacent wall draw a vertical line. Similarly, you need to draw a line on the opposite wall, and with a long rail line to connect the ceiling and the floor. Further, the angle of the wall should be marked vertical lines at a distance of 60 cm and are staggered to make a mark in 50 cm - they will be a place for mounting the fixing suspension.
When the drywall ceiling mounting inmatter of priority, it should be noted the horizontal level of the room. You can use lasers or gidrourovnya. All internal and external corners of the room put down a small mark, then in every corner of the measured distance from these ticks to-ceiling windows and a note with the value obtained distance. Such manipulation is needed to determine the lowest point of the ceiling, from which to push off when it is lowered.
It is important! When installing the ceiling wireframe minimum lowered to 4 cm from the lowest point.
Found height marked in each corner, andreceived marks are connected by rail with horizontal lines. Further installation is carried out on the perimeter of the profile. On the surface of the ceiling along the wall is stamped with an interval of 40 cm. Similarly, a mark on the opposite side, then connect the points obtained by parallel lines. Each line shall be marked in 50 cm in a checkerboard pattern, determining suspension of the installation site.
Conduct wiring for plasterboard
After setting all profiles should be ready to conduct communications: wiring, network, telephone and television cables.
Be aware! Regulations require electrical installation space beyond the gypsum sheathing power cables in the corrugated pipe, which does not support combustion. It can be plastic or metal hose corrugated labeled NG (non-combustible).
Wires with safe voltage ripple does not need to be, but it is able to protect the wiring from damage by sharp edges of the metal frame.
At this stage, consideration should be given the required number of points of consumption, to determine their location and the passage of wires.
It is important to know! The wire should extend vertically from the outlet or switch, and the horizontal portions of its passage should be placed at the same height as the junction boxes.
It is desirable to graphically display how the wire will be held, in order to avoid problems with its installation in the future.
Wires are attached to the wall for easy connection sockets length of wires should be left with a small margin from the surface.
How to cut
In order to properly and accurately cut a sheet of drywall will need the following tools: a long rack, pencil, tape measure, sharp knife.
Perform this work is very simple, you need to follow the steps:
- Marking sheet of drywall;
- Stage 2 on the marked line with a sharp knife cut through one layer of paper;
- It is necessary to fracture the sheet, and the plaster on the basis of slit fracture line;
- Holding the two halves of the sheet at right angles, it is necessary to cut through the back side of the paper layer.
Arisen uneven ends sticking paperIt should be sanded a plane designed for drywall, wood with a file or rasp with sandpaper. The end result is a portion of the sheet of drywall the required size with neat, smooth edges.
Chamfering on drywall
When interfacing sheets having nezavodskie edges should be chamfered at an angle of 45 degrees. At first slice is cut parallel to the paper with a space from the edge of 1 cm, and then a knife chamfered.
Subject to these recommendations, the paper on the front side of the sheet will not be lifted up.
How to make a cut-out
There are two types of cuts: the edge and in the middle of the sheet.
For the cut with the edge you need to partitionand cut with a knife on one side of the paper, and then make a jigsaw or hacksaw two cutting away from the edge. Gypsum boards should dislocate and dorezat the back of the paper.
To cut a hole in the middle of the sheet, it is necessary to saw the three sides, and then break. Or just completely cut out the hole.
Installation of drywall sheets in the profiles
After installation of the frame andpreparatory work should begin immediately for installation of drywall. For walls and ceilings, there is one way of fastening. It is necessary to closely attach the sheet to a finished frame such that one edge of the sheet positioned flush with the wall. Plasterboard sheets are attached to the profiles with self-tapping screws.
When the work is necessary to deepen the screwat such a distance that the tip is not performed, but was not located too deeply. It should be noted that at break of the upper layer of the cardboard mounting place is relaxing. The distance between the screws should be 20-25 cm.
If the ceiling height is greater than the size of canvasgypsum board, it is necessary to fix the intermediate profile. All parts of the sheet should be secured, as otherwise the joint position will be constantly crack. In this situation, the next panel, you start with extensibility, staggered - a bottom sheet, cutting the top and vice versa. With such reliability is achieved by a method of the assembly.
Treatment of joints and recesses of screws
After installation of drywall sheetsjoints should be treated with paintings and zashpatlevat deepening of self-tapping screws. For joints used gypsum mixture that when drying forms a very durable material. Edges bevelled compulsorily subjected to the primer.
In all joints with the factory edge gluedreinforcing mesh width of 80-100 mm. In a situation where one or both edges of the sheet are chamfered, to be cut along the grid and to prevent its exit plane. If in such a case to apply the conventional reinforcing mesh width, the entire surface will have putty layer 1-2 mm greater.
Attention! Reinforcing mesh should always be placed in the middle of putty.
About 60% of the deepening of the scope of the first layer is filled with putty, then the grid should be immersed in the putty and smooth. At the end of the remaining volume is filled recesses.
The recesses of the screws is also necessaryzashpatlevat, it needs to hold a trowel in different directions to fill the filler recess. After drying, it is drawn a bit, which is the normal situation. Final processing is carried recesses finishing putty.
Putty, primer before the finish
The surface of the drywall under the wallpaper, it is desirableproshpatlevat finishing putty that will ensure its monotony. The strength of adhesion will not change during these works. Before pasting the walls of wallpaper must be primed filler.
Hang tile on gypsum board can be directly on the surface of the cardboard, but before that it must be primed.
Having familiarized with the phased implementation of works,we can safely perform their own installation of the drywall. This process - installation of plasterboard with their hands describes visually, allowing to understand all the nuances.
