To perform a high-quality installation of drywall with your own hands, you will need some tools, the same as.
Screwdriver;
the building level is not shorter than 1.20 meters;
impact drill or puncher with a thin drill;
roulette;
special planer for GKL (optional);
square;
hammer;
metal scissors;
tracer cord chopping;
water level from 10 meters;
a simple pencil, marker, chalk, charcoal, graphite - whatever;
construction knife for cutting drywall.
It's minimum. Not counting, of course, consumables - the actual drywall sheets, guide profiles, materials for suspensions and hardware.
It is necessary to distinguish between the installation of GKL on the ceiling and on the walls. The technology has certain differences. Any drywall is mounted on a metal profile or on wooden blocks. If you decide to sheathe the ceiling, then you need to fix the profile at intervals of 35-45 cm. This means that you need to take into account that much more material will be required than when finishing plasterboard walls. And we also need vertical hangers, which are not on the walls. In the second case, the profile is fastened at intervals of approximately 60 cm, and additional horizontal fasteners are used, which are fixed with four (!) Self-tapping screws to avoid backlash.
Walls
Walls are marked in the simplest way. In the corners at a distance of five centimeters from the base of the ceiling, you need to draw a vertical line, controlling its level. In the opposite corner, another perfectly even vertical line is made in the same way. Further, with the help of a tracer, the drawn lines must be connected both along the floor and along the ceiling. The drawn line will become the perimeter of the future wall.
Further from the edge of the wall at a distance of 55-65 cm, it is necessary to mark vertical lines at the same level. Markings are made on them every 50 cm in a checkerboard pattern (place of installation of the ES fastener).
This is if you have flat ceilings and floors by default. Otherwise, the control points must be controlled horizontally with a water level.
The perimeter guides are the base. Next, we make a regular cage, bypassing niches and ledges. The length of the horizontal element ES is the distance of the finishing rails from the wall. You can do without them if you do not plan to insulate the walls. Then the finishing guides are attached directly to the wall.
It is cut with an ordinary construction knife, cut through to half the thickness of the sheet, then gently breaks off;
It is attached to the frame with self-tapping screws 3.5-4.5 cm long. The caps of the self-tapping screws are recessed in the sheet by 2-3 mm;
The distance between the screws is no more than 30 cm. According to professional experience;
It is marked and cut out not immediately by a wholesale batch, but as one sheet is mounted, the next one is measured;
Joints and mates should be in the middle of the guide profile;
It is advisable to chamfer at the joints. In advance, of course.
Ceiling
Before proceeding with the installation of drywall sheets on the ceiling, determine and establish the ideal horizontal level of the room. This is where the water level comes in handy again. It is easy to use and does not require any special purchase costs.
1. When beating the horizontal level in all corners of the room, both internal and external, put marks.
2. The distance to these marks (from the ceiling) is measured in each corner of the room. Next to each such mark, right on the wall, we write the corresponding distance. This will be necessary to accurately determine the lowest point of the base of the ceiling, from which, when installing materials, you will repel when you lower the ceiling in the room.
3. If it is supposed to fix the GKL with the help of profiles, then the ceiling in this case can be lowered by 4-5 cm, it will not work less. Based on this option, it is not difficult to calculate the optimal height to which the ceiling will fall.
4. Then all points are connected with a chopping cord. According to the obtained height along the perimeter, a U-profile is attached directly to the base. After that, along the two walls on the ceiling, you need to make marks 45-50 cm apart from each other, and connect them.
5. Now along the other walls, also on the ceiling, marks are also made every 40 cm. Opposite points are connected by lines. On the ceiling, parallel lines will be obtained after 40 cm.
6. Further on the lines that go through 50 cm, the future place is marked where the vertical suspension will be installed. On each adjacent line, the marks must be shifted by 25 cm. Suspensions on the ceiling are preferably mounted in a checkerboard pattern.
After all the markings, ES elements or knitting needles with an eye and a swivel suspension can be mounted on the ceiling. Then, with a mini-grinder or scissors for metal, the profile is cut to size, but not of the desired length, but about 1 cm less. Insert it into the U-profile that is on the wall. After installing the entire estimated number of profiles in the horizontal level, they are connected transversely with the fasteners of the “crab” system and the CD profile. Here is the frame on the ceiling and ready!
Let's continue with the ceiling. You will need a UD guide profile. Be sure to consider the height to which the ceiling will be lowered. If this height does not exceed 11-13 cm, the universal hanger ES 60/125 will suit you. If it is planned to lower the ceiling to a greater height, then you cannot do without a special knitting needle with an eye and a suspension with a swivel mechanism and an expanding element.
If it is planned to install the GKL on concrete, purchase a driven dowel. Wooden coating involves a special wood screw. Do not forget about the longitudinal connectors for the profile, crabs and self-tapping screws 9.5 and 25 mm.
The frame is ready, you can already proceed with the installation of the gypsum boards themselves. Both on the ceiling and on the wall, the sheets are attached in almost the same way. The material must adhere very tightly to the finished base.
Each drywall sheet is attached to the metal profile with self-tapping screws. The self-tapping screw should be screwed in so that its top does not protrude, but also not go deep into the drywall sheet. Do not fasten the screws close to each other in order to avoid breaking through the paper layer of the GKL. The optimal mounting distance is 25-30 cm.
After the drywall sheets are fixed, all seams are carefully puttied with a special putty with the participation of a reinforcing tape using a spatula and a small trowel.
Addition
When installing GKL on any basis, you should consider in what environment the material will be used. If the humidity of the room does not exceed the "usual" indicators, simple sheets of drywall will suit you. In all rooms with high humidity, it is necessary to use moisture-resistant plasterboard. Be sure to take into account the structure of the surface of the wall on which the plasterboard will be mounted. The size of the dowel will depend on the density of the material from which the wall is made.
