As a rule, for quality repairs it is necessary to create the most smooth and even surfaces of the ceiling and walls. This can be done using plasterboard sheets. Today we will look at what types of fastening drywall to the wall exist. And how to fix drywall on a wall without a profile.
The fastening of drywall to the wall is selected according to the purpose and the condition of the base. You can secure a sheet of plasterboard using either a frame or frameless method. Each of these types has its own characteristics and advantages.
The frame method is relevant in such cases as:
The main disadvantage of this method is the reduction usable area. In addition, do not forget that to complete it you will need screws, profiles and additional tools.
Attaching drywall to a wall without a profile (frameless method) does not significantly change the volume of the room, but is done when the surface is relatively flat and there are no plans to insulate it.
The main advantages of this method include simple and quick installation, low cost.
Attention! You cannot install gypsum boards if moisture accumulates on the walls or if there are areas affected by fungus. The surface must be dry and the fungus removed. At high humidity Indoors, it is worth buying a moisture-resistant type of drywall.
To do this we need a level, a tape measure, a pencil and a painting knife. How to cut drywall is easier to illustrate in the photo.
We measure with a tape measure exactly to the millimeter. We mark marks for the future cut on the drywall with a pencil. mark 0.5 cm less than measured so that there are no problems in installing the sheet.
Apply a level and cut a straight line with a knife.
We break the sheet along the line and cut through a layer of paper on the other side.
Let's look at ways to attach drywall to a wall without a profile. In practice, several options are used for how to level a wall with plasterboard without a profile:
It is recommended to sheathe walls using self-tapping screws in cases where the base itself has a wooden (OSB, plywood, timber) or plaster surface. Let's look at how to screw drywall to a wall step by step using self-tapping screws:
The main thing is not to overdo it. Tightening the screws too tightly may screw through, or the gypsum board may crack.
I do not recommend this method of fastening with dowels. But if there is no way out and the surface is relatively flat, then you can resort to this method.
The option for attaching gypsum boards to dowels is as follows:
Attention! It should also be taken into account temperature regime premises, it should not be below +10 degrees Celsius. At lower values, you will need to worry about heating the room.
When installing drywall directly onto a wall using gluing technology, careful preparation of the surface is required. It consists of removing wallpaper, parts of peeling paint or plaster, sealing cracks, and applying a primer with an antiseptic (preferably in two layers).
Pull the thread or use laser level to understand how curved the surface is and what layer of glue we need. If the wall is smooth, then you can glue the drywall under a special spatula (comb). But usually the walls are very crooked and you will need to apply glue buns.
It can be used as special gypsum glue (dries very quickly), or you can use tile adhesive (you can work with it for a long time). For one batch of glue, it is recommended to install no more than two sheets of drywall.
Glue buns are applied at a distance of 30 cm from each other. A sheet of gypsum board is applied and a level is gradually tapped and applied. Using the level, we determine how evenly the sheet is glued, put it in different directions and planes so that there is no deflection of the sheet. We hammer glue into the resulting cracks along the edges. Let's start gluing the next sheet. Do not forget to leave a small gap of 2-3 mm between the sheets for subsequent finishing.
After the glue has completely dried, the sheets can be reinforced
This method of installing sheets allows you to quickly level the surface without using a profile and save on the purchase of materials and work. Fasten the material to base surface can be done using hardware or applying adhesive mass. The easiest way is if you have a flat wooden surface - just apply it and twist it. Gluing drywall requires a certain skill, and if we use gypsum glue, then also speed of work.
After installing the plasterboard sheets, you can seal the seams and begin subsequent finishing.
Drywall firmly occupies the position of one of the most popular among construction and finishing materials, and this is easily explained by its many advantages. These include its environmental friendliness, ease of installation, the ability to use in the most different rooms, relatively small weight and generally available cost.
Plasterboard sheets are used for leveling walls and for, moreover, working with them is possible not only an experienced builder, but also for the beginning master. Finishing walls with plasterboard without a frame and profile is possible using different adhesives and on surfaces built from various materials. The advantages of such fastening compared to frame method are that the reduction in the area of the room is not so noticeable, a decent amount is saved on the elements of the sheathing, and the installation work pass quickly enough and can easily be produced on their own.
To evaluate the advantage frameless installation plasterboard, you can briefly consider both existing methods by comparing them.
To be fair, it should be noted that sometimes when installing drywall it is impossible to do without installing a frame, so this case is also worth mentioning when considering methods for installing the material.
So, there are two main technologies for attaching plasterboard sheets to the wall in order to level it:
This publication will consider the nuances of only frameless fastening of drywall.
To level walls with plasterboard using one of the adhesives, you will need much fewer tools than if a frame was attached to the wall. The list of everything necessary consists of the following items:
drywall
Now it is necessary to consider the materials that will be required to prepare the surface of the walls and for high-quality installation drywall:
About some materials - a little more detail.
The Knauf company produces not only a variety of construction and finishing mixtures, but also plasterboard sheets for various purposes - it is simple, moisture-resistant, fire-resistant and moisture-fire-resistant finishing material:
Here we can briefly say about, which does not require special effort, experience and special tools– it is enough to have a regular sharp stationery knife on hand. The cutting process takes place in the following order:
Taking wall measurements. This is necessary in order to plan the future placement of drywall sheets. It is also necessary avoid cross joints, since the sheets will be offset.
Preparing the wall surface. At this stage, the surface should be cleaned of old wallpaper, traces of paint, and whitewash. Necessary identify protruding places on the wall, then mark them with chalk. Next, several layers are applied to the wall. soil mixture and dries completely.
Before attaching the frame to the wall, it is necessary to cut strips 100 mm wide from plasterboard, after which one of the sides is coated with a primer. Next, glue is applied to the strips, then they are glued along the wall, one close to the ceiling, the second to the floor. Be sure to take into account the fact that you need to work with glue as quickly as possible, you shouldn’t knead a lot at once.
Preparation of the bulk of the glue. For this purpose, slow-setting gypsum mixtures or building gypsum are often used. In the second case, it is necessary to prolong the hardening by adding PVA glue to the adhesive composition. Therefore, if you want to attach drywall to a wall without a frame, and act carefully, you need to provide these details.
Attaching sheets to the wall. The thickness of the adhesive layer will depend on the degree of curvature of the surface. If it is relatively flat, then you can glue directly onto it. The adhesive composition is applied notched trowel, it or a trowel can be used to perform the technology.
Fastening drywall to a wall without a frame involves leveling the large curvature of the walls; for this purpose, special "beacons", which are made from strips of plasterboard. Usually they are glued vertically along the perimeter, the interval is 40-50 cm. From the very beginning, the left and right beacons are set, and then, using a fishing line that is stretched between them, they are attached vertical stripes. As for the upper and lower horizontal beacons, they are aligned using a certain rule, which is used to press the sheets of drywall.
Installing drywall on walls without a frame is carried out in a few simple steps, and they need to be done gradually.
After applying the glue it is necessary take pads measuring 10-20 mm from the floor and install a sheet of drywall on them. Thanks to this technique, compensation for sheet elongation will be provided at a time when the humidity and temperature in the room changes. Sheet needed level using a special rubber hammer, tapping it lightly.
After gluing the drywall to the wall and the glue has hardened, it is necessary secure it with dowel nails. In this way, the durability as well as the reliability of the fastening can be increased. To do this, you need to drill a hole in the drywall, then insert a dowel into which a nail is driven. The nail must be struck until the head is completely sunk into the drywall. IN in this case the main thing is not to overdo it and not damage the drywall.
Thus, facing walls with plasterboard without a frame is carried out as quickly as possible if the sequence of actions is followed.
In this case, there are two main methods of attaching drywall - using a frame made of wooden bars and metal.
There are two main steps when using the method: assembly of the frame, then installation of drywall bars. The assembly process begins with sequential fixation of the guides. Unlike a procedure such as leveling walls with plasterboard without a frame, this will require put in more effort. It is also necessary to select the appropriate fastening - this can be a dowel-nail, self-tapping screws with a large pitch, depending on the base material.
To correctly align the guides and the entire frame, strips of veneer and a level are used. After installing the guides, you need to set and then fix the main bars. Drywall on wooden walls It is also attached using special technologies.
Unlike the previous installation method, this one has its own characteristics. On the one side, it allows you to create new designs- these are arches, niches, partitions, on the other hand - it requires a lot of money and effort. In addition, if conditions change environment Wood is subject to deformation, so the quality of the entire structure may deteriorate significantly.
Most often they use plasterboard, which today, due to its advantages, is one of the most the best ways internal lining. Usually, for its installation, a special sheathing is constructed from a metal profile, but this may not always be advisable. In small rooms, for example, installing a frame will reduce its already small area.
To attach drywall to walls without lathing, you will need the following materials and tools:
The initial stage of work is taking measurements of the room and cutting materials. Based on the measurement results, you can consider options for the arrangement of sheets and determine the most acceptable one. If the ceiling height exceeds 2.5 meters, in addition to standard sheets You will need inserts that need to be cut out first.
The process of cutting and cutting drywall for inserts is as follows:
The next step is preparing the base. Depending on the material from which the walls are decorated, various measures are taken to prepare it. Yes, for brickwork It will be enough to treat it with a primer mixture.
If the surface has been plastered, to avoid peeling of the putty and deformation of the slab, all coating should be removed, including all layers of finish, then immediately apply a primer coat.
If difficulties arise in the process of removing the old base, you will need to use a metal brush, with which dust, dirt and deposits are removed from the wall.
If during work the finish peels off from the base, you should carefully plaster the potholes so that the surface is smooth.
Let's take a closer look at the process of preparing the wall surface:
For work with drywall that does not require the installation of a frame for attaching drywall, adhesive mixtures are used. Since drywall is used for interior decoration, the basis of dry compositions is gypsum. Instead of glue, you can use starting putty or alabaster, but to increase adhesion you will have to add PVA glue or wallpaper glue to the water.
Let's consider several ways to use the solution:
A solution for fixing drywall to walls is prepared from a powder mixture and water. To prepare a 10-liter bucket, fill it a third with water and add the mixture little by little, constantly stirring it with a mixer or drill at low speed.
Knead the solution for less than 5 minutes, then take a short break and beat again, this will break up all the dry lumps. The consistency of the solution should resemble mashed potatoes.
Fixing mixtures, regardless of the manufacturer, harden fairly quickly, however, subsequent finishing of drywall can begin no earlier than after 24 hours.
There are several ways to frameless fasten drywall:
Let's get acquainted with the features of installing the material on a base with varying degrees of differences:
After completing the installation of drywall using a frameless method, the joints between the sheets should be securely sealed. At this stage, the joints are filled with putty and reinforcing glass tape is glued, which is covered finishing layer plaster.
After the surface has dried, all irregularities and roughness are rubbed off using sanding paper.
It is important to reliably align and adhere the material to the openings for windows and doors. Indoors with plastic windows finishing of the fit is carried out using a plastic profile. The gaps above the floor are covered with plinth, and the gaps under the ceiling are puttied or covered with ceiling plinth.
Installation of drywall can be carried out on walls and ceilings in two main ways: on the frame and directly on the wall.
Frameless installation involves fixing sheets of drywall directly to the surface, without first creating a frame. The choice of method depends on the unevenness of the wall or ceiling.
It can be produced in three ways:
For this method, gypsum boards with a thickness of no more than 12 millimeters are used. The height of such a structure can be 3 meters.
Cladding gypsum board walls using a frameless method is used:
The frameless fastening method can be used in cases where the unevenness of the wall does not exceed 2 centimeters in some places. It is used on various surfaces: concrete, brick, block; under certain conditions, timber walls can also be covered with plasterboard.
The advantages of this method include:
The disadvantages include the fact that this option can only be used on flat surfaces. If the unevenness is large, you will have to first prepare the wall: level it using beacons. It's pretty labor-intensive process, which not everyone can do on their own.
With this wall decoration it is quite difficult to install communications inside. In addition, there are few insulation options with this design. The most commonly used material is polystyrene foam, which not everyone likes because it is not environmentally friendly.
Methods for fixing material to the wall can be as follows:
Preparing the foundation - the very first and important stage surface decoration.
It includes the following steps:
The smoother the surface where installation is carried out, the more high-quality drywall available. Attaching drywall to the wall using a frameless method is easy to do yourself. It is easier and faster to do such work together. Before you begin installation, you should take care of purchasing materials and tools.
To carry out the work you need to buy:
Tools:
If necessary, you need to pre-plaster separate sections of the surface or the entire wall.
After preparatory work, let's start installation.
Glue method:
It is necessary to leave small gaps at the bottom and top using gypsum putty:
This is how all gypsum boards are attached to the wall.
Because the glue mixture tends to harden quickly, it must be used promptly. It is advisable that the container be used within a maximum of half an hour. In this regard, it is recommended not to completely fill the entire composition, making fresh glue for each new sheet.
The final stage includes the following types works:
The corners are secured with mounting adhesive. The resulting protrusion, no larger than 1 millimeter in size, can be easily removed with a putty solution.
Advice! It is imperative to seal joints and corners when surface painting is used as a finishing touch.
Installation of drywall without frame for 1 square meter costs from 500 rubles. Exact prices can be found in construction company When applying, they are calculated taking into account all the nuances, in accordance with the project.
Installation may include the following work: lining of pipes and communications, installation of heat and sound insulation, putty, priming the surface for painting on gypsum board.
