Have you decided to fulfill your old dream and make repairs in the house? And where without material such as drywall? With it, you can align all the walls in the house, make new partitions. Of course, the strength of the material is not very high, but it is perfectly suited for use in everyday life. Here is just one question at the initial stage can put the masters into a dead end: and which side to fix the drywall? The fact is that his sides are painted in various colors. This is what prompts the idea that somewhere there is a catch and such coloring is not without reason.
A little bit about drywall sheets
Building new partitions is not so difficult. Of course, if you make them from brick or cinder block, it will take a lot of time to kill to make the base, then to masonry, and then apply a layer of plaster. But plasterboard sheets allow the task to be simplified many times. If there is no need to erect a capital wall, then this light and relatively durable material can be used. Our article will tell you which side to attach the drywall to the profile.
The basic methods of working with the material will also be described. The advantage of GCR is that with its help you can very quickly and efficiently level all surfaces - walls, ceiling. But which side to fix the drywall to the wall and how to properly prepare? We will talk about this a little further. In addition, when using GCR, the heat and noise insulation of rooms increases. And most importantly, even a beginner can work with drywall sheets, since it is simple and convenient to use.
Tools required for working with GKL
Before starting work, you need to prepare the entire tool for working with drywall. First you need to prepare a frame that is firmly fixed to the ceiling and walls during the construction of partitions. To carry out installation work, you need to stock up on the following tools:
- Level.
- With a pencil.
- Thin rope or fishing line.
- The hammer.
- Plumb.
- Tape measure.
- With a construction knife.
- Scissors or a hacksaw on drywall (metal can be used).
- Puncher.
- With a screwdriver.
- The square.
- Drywall grater.
It should be noted right away that a punch is not always needed - only if the walls are made of concrete and it is impossible to drill holes in them with a conventional drill. In most cases, you can use a simple drill or hammer, as well as a plumage drill.
Materials for work
The simplest version of GKL fastening to the walls is to install it on a frame of wooden beams. But it would be better if you apply a profile for drywall, its price is not very high. In specialized stores it can be purchased at 40 rubles per linear meter and above. It all depends on what type of profile you need. There are two profile options:
- D - is designed to form a plane for drywall fasteners.
- W - with its help it is possible to carry out the construction of a common frame of the structure
In addition, each of the options can be divided into a guide and reference type. In the specifications they are indicated by the Latin letters U and C, respectively. Guide profiles are a common component of the frame. Its main difference is that it has smooth walls and a shape like that of the letter P. It is in it that the support profile is fixed. The latter is slightly ribbed, which can significantly increase bending stiffness.
Profile Features
Now consider the features of various profiles for drywall. It is recommended to check the price in stores specializing in the sale of materials. The fact is that the cost varies, depending on what type of profile.
In the manufacture of the frame, the following materials are used:
- CD is a profile which carries out bearing functions, has a size of 60x27 mm.
- UD is an element that carries guiding functions. He has a size of 28x27 mm; with his help, a CD type profile is fixed.
- CW - refers to the rack elements, it is necessary to create a wall frame. The profile is 50 mm high, and the width is represented by three sizes - 50, 75 and 100 mm.
- UWs are guides designed for use with CW profiles. Element height 40 mm, width, as in the previous case - 50, 75 and 100 mm.
There are also enhanced versions of profiles, for example, indicated by the abbreviation UA. This is an enhanced version of CW. It differs in that the walls of the profile are somewhat thicker. When constructing narrow partitions with a width of not more than 10 cm, it is recommended to mount the UA and CW elements. If you need to build a thicker wall, then you need to use profiles UD and CD. In this case, on each side of the frame, two guide elements must be placed in parallel.
Which sheet to use?
But which side should the drywall be attached to the frame? We will answer this question a little later, since we need to deal with some more points. The most important thing - when buying a material, look at what color it is. For example, for the construction of walls and partitions in the kitchen, green GCR is best suited. The same is used in bathrooms and toilets. Green color means that gypsum plasterboard is moisture resistant. The sheet thickness should be 12.5 mm.
What do you need when installing the frame?
When installing the frame, it is necessary to use a crab and a direct suspension. A crab is a universal connector. In order to assemble all the elements into an integral design, you need to use the so-called self-tapping fleas. Their tip should be made in the form of a drill. But the gypsum plasterboard fasteners to the frame must be produced using 3.5x35 mm self-tapping screws, in which the head is countersunk.
In addition, when erecting walls and partitions from drywall, you will need the presence of nylon dowels and screws. With their help, you need to fix the frame on the walls and ceiling of the room. Also, the presence of heat-insulating materials will be required to fill the internal cavity of the created partition.
Frame mounting
The first step is to level the floor and the walls adjacent to it. In other words, you need to prepare these surfaces for applying the finish. First mark on the floor. And be sure to consider all the nuances below. In most cases, the corners between adjacent walls are not straight. Especially in old houses. When marking new partitions, it is necessary to bind simultaneously to two walls located in parallel. In this case, you will be able to visually reduce the curvature of the room.
If you are building not only a partition, but also fastening plasterboard sheets on the walls, first withdraw the frame around the entire perimeter, and only then proceed with the installation of a new structural element. When drawing the first line on the floor, bear in mind that it will mark the edge of the guide element. It is necessary to add to it the thickness of the drywall sheet, the putty mixture, as well as the topcoat.
Marking lines
To transfer the line drawn on the floor to the ceiling, a plumb line must be used. You will simplify the work if you use the laser level. Then you can proceed with the installation of UW profiles. They need to be fixed on the ceiling and on the floor. After that, install the support posts - you make them from CW profiles. It also needs to be applied in those places where it is planned to install a door or other opening.
First of all, fix the support posts on the lower profiles. The front side must be located inside the openings. It is allowed to strengthen the supports with timber bars. They need to be inserted inside elements located vertically. Fixation is carried out using self-tapping screws. When you fix all the profiles, proceed to the fastening of the support elements CW. The first part is placed so that there is a distance of 550 mm from the bearing wall. The remaining parts must be fixed at a distance of 600 mm from each other.
Now you know what profile is needed for drywall and how to properly fix it on the walls. And now we proceed directly to the installation of sheets on the frame.
GKL fasteners and cutting
In order to build the entire structure correctly, it is necessary to qualitatively fasten the gypsum fiberboard to the frame. The overall dimensions of the sheets are standardized. They are 1200 mm wide and 2000, 2500 and 3000 mm long. In the event that the ceilings in the premises are high, then at least two gypsum plasterboard elements must be installed vertically. The first sheet needs to be fixed near the main wall. Then be sure to remove the chamfer on the side. To do this, cut 5 cm from the GCR with a special knife.
Do everything on flat and hard surfaces so that the sheet does not bend. Lay the sheet on the surface, on it with a pencil outline the line along which the cut should be made. Then, using a construction knife, you need to cut the material. Remove the top layer, and then combine this line with the edge of the hard base. And then the drywall sheet breaks very easily after that.
It should be noted that the front side of drywall has the following properties:
- There are no factory markings on it. They are present only on the back.
- The color with which the front side is pasted also processed all the side edges.
- On the front part, a different composition is used. It has a lot of cellulose, which reduces the consumption of materials used in decoration.
Fasteners to the frame are made using screws 3.5x35 mm. First you need to fix the corners of the sheet, and then the middle part. The interval between the screws is 250 mm. It is not recommended to make the distance larger, but it can be reduced to 100 mm. Screws need to be screwed in until the caps go deep into the sheet. In other words, they should not peek above the surface.
And a little about how to close up seams on drywall. Putty first to get rid of cracks. Nothing complicated, but you have to carry out all the work carefully. Then, when these areas are dry, you need to apply a leveling layer on the entire surface of the sheets. The entire wall should be perfectly flat. Only after this can the topcoat be applied - water-based paint, wallpaper or tile.
