Almost always, before interior decoration, walls are aligned. They do this in several ways, but the most convenient of all is plasterboard casing. To work with this material does not require special skills, it is very easy to cut, just fastens and allows you to get a perfectly flat surface. Since the installation is quite simple, do-it-yourself wall decoration with drywall does not take too much time and allows you to save money.
Drywall Advantages
Drywall - a unique building material for wall cladding, having many advantages:
- the ability to get the perfect surface;
- drywall is easy to handle;
- easy to cut;
- it can be bent and given the desired shape;
- light weight;
- Fire safety;
- it is fireproof and non-combustible material;
- has good heat and sound insulation properties;
- ecological cleanliness;
- affordable cost;
- spot repair behavior is possible with minimal expense and time.
In addition, communications, drywall insulation can be placed between drywall and flooring. Also, the use of this material makes it possible to produce shelves and niches built directly into the wall, which is a big plus in small-sized apartments.
Installation methods
Wall decoration in the house with drywall can be carried out in two main ways:
- By erecting the frame and screwing to it GCR.
- By gluing drywall to the wall.
In some cases, both options are combined.
The most reliable way to decorate walls and ceilings with drywall is the frame option. The frame is formed using a special metal profile for GCR, to which the sheets themselves are screwed. Among the disadvantages of this method can be identified the complexity of the installation, additional costs for materials and the fact that the design takes up a lot of space.
Attaching GKL to glue is a simpler and cheaper way, but is possible only with a slight curvature of the surface. In addition, the strength of such a finish will be less.
Further we will consider how to do wall decoration with drywall in a wooden house with your own hands.
Work sequence
- Preparatory work.
- Markup.
- Installation of metal profiles.
- GKL mount.
- Sealing up the seams.
Preparatory work
Before decorating the wooden walls with drywall, the room must be freed from unnecessary and bulky objects, remove the old coating to the very base, remove communications and wiring. Since the covering will cover all defects and irregularities, there is no need to level the walls. Coat all existing cracks and cracks with putty. Then the surface needs to be cleared of dust and to execute a primer.
What will be needed for work
- GKL.
- Metal supporting profiles and guides.
- Pencil.
- Building level.
- U-shaped brackets.
- Roulette.
- Sharp knife.
- Capacity for putty.
- Reinforcing tape.
- Hacksaw.
- Spatulas.
- Self-tapping screws.
- Screwdriver.
- Insulation.
Installation of guide metal profiles
First of all, you need to prepare the floor along the walls. It should be clean and even. Then, stepping back a little from the wall, draw a line to mark the guide profile. If the lining is carried out on all walls, the marking is done parallel to each wall and is connected at an angle of 90 °. Further along the line, a guide profile is applied and screwed to the floor with screws.
One profile has a length of 3 m. The extension is carried out using special metal connectors and screws, the length of which is 9.5 mm. To make an angular connection, the end of the profile is cut from both sides, then the sides are bent and the screws are screwed to the side edge of the other profile. Vertical guides are fixed on the sides of the walls: the lower ends of the profiles are inserted into the floor profile, they are vertically aligned using a plumb line. Screw to the ceiling and at the base. The ends of the ceiling guide profile are inserted into the left and right wall profiles, aligned with the floor profile and then screwed.
Installation of carrier profiles
To mount the supporting profiles, it is necessary to make markings on the wall. To do this, from the ceiling to the floor, vertical lines are drawn every 40-60 cm. Further along the marking, after 60 cm in height, U-shaped brackets are mounted to the wall. If the wall is wooden, the brackets are fixed with self-tapping screws, if concrete or brick - with dowels, nails. After that, the load-bearing profiles are inserted into the upper and lower guides, they are parallel to the markings and screwed on both sides with screws. At the last stage, each profile is vertically strengthened with brackets.
Communication lining
After the frame is installed, wiring and communication pipes are laid between the profiles. Across the entire plane, they must not extend beyond the guides. Communications are fixed to the wall surface with special clamps and brackets. It is important to pay attention to sealing pipe joints and wire insulation, since drywall will have to be removed to fix the damage.
Warming
If the walls are insulated from the outside, you can do without internal thermal insulation. Although under the casing, the insulation layer will not be superfluous. This material has high soundproofing properties. Before laying the insulation, it is cut into strips, the width of which is 2-3 cm greater than the distance between the profiles. Then it is tightly laid so that there are no gaps.
Drywall wall decoration
Cut out GCR sequentially. To cut the material evenly, draw a line on its surface and cut it with a knife. Further, according to the marking, the sheet is broken and cut on the other side.
Drywall wall decoration starts from the corner. For this:
- The first sheet is applied to the supporting profile, aligned at the edges and screwed to the posts with self-tapping screws every 25-30 cm.
- The second sheet is screwed next to it. Joints need to be combined on the supporting profile.
- Before installing the carbon fiber coating at the exit points of communications, holes are cut in the sheet.
Stitching
Since GCRs have rounded or truncated edges, grooves form at the seams when joined. To seal them you will need:
- putty;
- reinforcing tape;
- putty knife.
First of all, it is necessary to knead the starting putty, then cut off a piece of the reinforcing tape, apply the putty mixture on the seam, attach the tape on top, and carefully straighten it in the center of the joint. Then again put the putty and distribute it well with a spatula. After the solution has dried, it is necessary to process the joints with fine sandpaper.
Wall finishing
In order to get rid of even the slightest defects, GKL is coated with a very thin layer of putty on top. This is done with a wide metal spatula. Work starts from the edge of the wall. A solution is collected on a spatula, put it on the wall surface at an angle of 10 °, pressed from the bottom and lead up.
If the walls are painted, two layers of putty are applied. The surface is ground, then primed. After that, the walls can be pasted with wallpaper, painted or covered with decorative plaster.
Frameless wall cladding
Drywall wall decoration can be carried out without the use of profiles. This option is used in the following cases:
- when the height of the walls is not more than 2.5 m;
- vertical deviation does not exceed 2 cm;
- no insulation required;
- if the room is dry and there are no sudden changes in temperature.
You can not glue GKL on decorative plaster, wallpaper or old peeling paint, since such wall decoration with drywall will not last long.
Wall preparation
A wooden or concrete base is well cleaned of dust, and all cracks are closed. If paint is applied to the walls and it holds firmly, you can not remove it. It is enough to make small horizontal and vertical notches every 25-30 cm. Then the surface is primed and dried.
Stacking communications
If the wiring is low current, it can be fixed directly to the surface. To lay the power electric cables and communication pipes, it is necessary to break the strobes in the wall, then close them with special strips and seal the joints with putty.
Drywall Mount
Wall decoration with drywall is as follows. Glue is diluted according to the instructions, then with the help of a notched trowel, apply it to the back of the GCR with one wide strip around the perimeter and two stripes in the center. Having completed the mounting wedges from below , they apply the sheets to the wall, align and press well. Level check verticality and horizontalness. In the same way, the next sheet is attached, while trying to dock it as tightly as possible with the previous one.
After fixing the gypsum plaster, seams are sealed. If they are thin and have a width of not more than 4 mm, they can simply be puttied, and for the wider, reinforcing tape is additionally used. Also, joints can be filled with glue. Plastered places must be sanded with fine sandpaper and cleaned of dust. The gap formed between the floor and the gypsum plaster is preferably filled with a waterproof sealant.
At the final stage, the surface is leveled with finishing putty, sanded, dusted and primed. Finished walls can be whitewashed, painted or wallpapered.
The price of wall decoration with drywall is different and depends on many factors. On average, it is 300 rubles / m 2 .
