Sticky wallpaper on drywall

Drywall can be safely called one of the most versatile building materials. Today, it is widely available. With it, you can, for example, straighten deformed parts of the room or level the ceiling. But this possibility of drywall is not limited. With the help of it, it is really possible to create designs with a unique design solution. This material is ideal if you need to make a perfectly flat surface, for example, under the wallpaper. Next, let's talk about how to properly make them stick to the plasterboard base.

Basics of performing

In addition to installing drywall sheets, before the wallpapering, you will have to do a lot of work to prepare the walls forfinishing finish. In particular, it is required to carry out priming, puttying and grinding.

Before starting work, it is necessary to carefully inspect the working surface of the walls of plasterboard. This must be done, even if previously the surfaces have already been examined. If minor defects are identified, they must be eliminated. For example, on the surface of the hub pins dowels may not be fully recessed or self-tapping screws may not be screwed. If these defects are visually invisible, then it is possible to draw a surface with a spatula. If there are defects, the tool will touch them, which will be reflected by a characteristic sound. Unfeded self-tapping screws must be tightened before gluing the wallpaper.

If the hat passed through the cardboard layer from the outside and sits deep in the gypsum base, then the drywall will not hold tightly at this point. In such cases it is recommended to get the screw and fix the material to the guide properly, having retreated from the previous place at least 55 mm.

How to glue wallpaper on gypsum board? To answer this question, you should know that you first need to check all available sheet joints. When installing on the joints of the material, chamfers are usually made. If they are not, then they are cut with a sharp knife. Chamfers should be made at an angle of 45 degrees by about 2/3 of the thickness of the sheet. This requirement must always be fulfilled, even if the joints were finely crimped. Otherwise, in a place where there are joints of two sheets, in due course there can be cracks.

In addition, you need to check that there are no paper debris on the work surface. If any, they must be carefully trimmed. After that you need to clean up the place with the help of a skin. The surface must also be thoroughly cleaned of dust and other building debris. Next, consider what to handle drywall before wallpapering.

Application to the surface of the

primer After the above work has been carried out, the walls must be thoroughly primed. This will help protect them from the appearance of the fungus. In addition, it will improve the grasping ability of putty with the working surface. Often as a primer mix, use an acrylic primer GKL-1 or another brand. In this case, it will be fairly simple to paste non-woven wallpaper on gypsum board.

The choice of primer usually depends on the conditions in a particular room. For example, acrylic blends with antibacterial additives are recommended for use in rooms that previously had problems with fungi and mold. Apply a primer better with a soft roller. You can use a wide brush for this purpose.

Gypsum plaster board

This stage should be carried out in any case before the wallpaper is pasted. And this is justified by several reasons. First of all, we must not forget that any wallpaper is relatively short-lived. So sooner or later you need to change them. If there is no putty, then you have to glue the new wallpaper on the old ones, which if you can remove it, then, most likely, with the top layer of gypsum. Sometimes they decide to paste them over old ones. If in this case the new material has a lighter color, then it is likely that old dark wallpapers will be visible through it. This is another reason for plasterboard plastering before gluing.

In addition, joints and seams between sheets of gypsum board can be gleamed without the putty through a layer of new wallpaper. This is especially noticeable if a material that has a light tint is used. If before putting the wallpaper on the drywall, putty the work surface, then it is possible to reduce the costs of repair in the future. Finally, putty makes the appearance of the wall more attractive.

There are two types of putty: starting and finishing. The first is usually applied starting. Its task, first of all, is alignment of the working surface. The main function of the finishing mix is ​​to hide minor defects on the walls and carefully level the surface. Today, you can find shpaklevki in the ready-made form, as well as those that require further preparation. Putty, the basis of which is cement or gypsum, when mixed with water mix with a mixer. The correct proportions of water and mixtures are usually indicated on the package.

Now let's take a closer look at the plasterboard plastering scheme:

1. First, the surface of the plasterboard is primed. For this purpose it is recommended to choose an acrylic primer that can improve the adhesion of the material to the putty. In addition, this mixture protects the surface from the occurrence of mold and fungi.
2. Then proceed to puttying the joints of plasterboard. During these works, it is necessary to use a mesh tape made of fiberglass, called a serpent. It can also be made from lavsan. By its kind and structure, this grid is somewhat like a normal medical bandage.
3. The main task of the Serbian woman is to hide the joints between neighboring sheets of plasterboard. In addition, it allows you to "hide" the small cracks and holes that are in the wall. This tape is glued to the joint of neighboring gipsokartonnyh sheets. Sickle, as a rule, is well impregnated with a special sticky substance, so it keeps perfectly. If the tape is unstuck, then it can be fixed with PVA.
4. When the tape is glued, apply a small amount of putty and level the surface. Surplus mixtures should be removed using sandpaper. This, for example, concerns how to glue wallpaper on the ceiling of gypsum board, and on the walls.
5. The next step is to fill in the places where the gypsum boards are fastened with screws.
6. Then it should be completely treated with a putty mix of a wall of drywall sheets. It is best to do this in three stages. And each next layer should be applied only after the previous one has dried.
7. The next step is grinding the dried primer with sandpaper. And, in order to make the surface smooth, the wall is first treated with a coarse-grained, and then with a smaller sandpaper.
8. Now the surface is again covered with a primer. This time already under the wallpaper. In this case, the chosen glue will not be absorbed too quickly, which will facilitate the further process of gluing. In addition, this allows you to improve the bonding of wallpaper with the wall. Cover the work surface with a primer two times.
9. As mentioned above, the primer is preferably applied with a roller or a wide brush. It is important to ensure that the entire surface to be treated is evenly smeared. In addition, when applying a putty mixture it is desirable to use a set of spatulas that differ in width. For example, with the help of a narrow tool it is convenient to take the filler, and with the help of a wide tool it should be applied to the working surface.
10. To prevent the wall from cracking in the future and to be more durable, it is recommended that reinforcing tape be used when laying joints. Before grouting the grooves, it is necessary to apply paint to the heads of the screws. It can protect the metal from rust formation, so that the screws will last longer.
11. For spackling operations, various types of mixtures should be used. Thus, for the first two layers, as a rule, a starting putty will be required, the filler of which is characterized by a larger fraction. The final layer of the final mixture, which has a finely dispersed filler.
12. To finally level the wall, putty should be polished. It is important to know that you can not erase the material when grinding is too intense. Otherwise, the whole process will have to start again. When this is done, you can start directly pasting drywall wallpaper. In order not to inhale dust harmful to your health during work, you need to wear a face mask.

How to paste wallpaper on a drywall

To determine how much you will need to purchase wallpaper, you need to know the exact length of all the walls, as well as the height of the ceiling. When this is known, it follows from the obtained total area to subtract the size of the openings for windows and doors.

When choosing wallpaper, you should pay attention to the numbers of lots that are usually put on rolls. They must coincide. In addition to wallpaper, you need to choose the right wallpaper paste. For this, first of all, it is necessary to adhere to the recommendations, which are specified in the instruction. Therefore, first you need to choose the wallpaper, and after that buy them glue. This is also true when sticking vinyl wallpaper on gypsum board.

To prepare the glue, mix the dry mixture with water and leave it in that condition for a while. If the weight of the wallpaper is large enough for drywall, then it is recommended to use a special adhesive compound to ensure a stronger adhesion. In addition, it should be applied glue both on wallpaper and on the wall. Otherwise, the technology of pasting wallpapers on gypsum boards is almost the same as on other surfaces.

When preparing glue, it is important to observe the proportions that are usually indicated directly on the package. When the mixture is ready, it should be left for half an hour. During this time, you can prepare wallpaper for drywall, make the necessary measurements.

Procedure for gluing:

1. Before gluing material, take a level or a plumb line and use them to draw a vertical. It is on it will be aligned the first sheet.
2. Then the wallpaper is cut to the desired length, while it should be top and bottom as a reserve for the undercut to leave a few centimeters. At once all the material is not worth cutting. It is better to do this as needed. The fact is that the ceiling or floor line may not be strictly horizontal. Therefore, different lengths of material are sometimes required for different sites.
3. If the wallpaper has a large repeating pattern, which during work needs to be combined with adjacent sheets, then you should buy the material with a large margin. Cut off the cloth to be smeared with a continuous layer of glue, especially carefully working the edges. Then the sheet, which has been glued with glue, should be folded in half so that it can soak up properly. This applies to medium and high density materials. If the wallpaper is thin( for example, paper), then fold them in half is not necessary. In addition, it is necessary to glue them immediately, while under the influence of moisture they are not deformed or stretched.
4. When glued wallpaper, it is desirable to align them on the top line. The web is applied to the prepared surface and is smoothed in the direction from the middle to the edges. This is best done with a plastic spatula or roller. If everything is done correctly, "bubbles" and "humpbacks" will not be formed.
5. It is desirable to once again glue along the edges of the wallpaper. If some sites have dried up and are not glued to the surface, then they need to apply a small amount of adhesive. Remains of glue should be wiped with a cloth.

When you paste wallpaper on gypsum board, you should not forget that if you can not join adjacent canvases, then you can overlap them. When the pasted areas dry, you will need to cut the vertical line under the ruler along the seam line, while removing the inner and removing the outer cut strip. When this is done, the resulting joint will be smeared with glue and smooth with a roller.

It is often difficult to match the wallpaper in the corner of the room. In this case, you can use the same method that was just described. Walls need to be glued entirely, and when they dry, then in the places where switches and sockets should be located, it is recommended to make two cross-cut incisions. Then the formed corners are carefully bent and with the help of a knife or scissors the contour is cut out according to the shape of the rosette.

Do not forget that the indentation is also done on the side that is pasted on the ceiling. In this area, cut off excess is best after the canvas has completely dried. This is usually done as follows: using a wide spatula, the edge is carefully attached and a superfluous part is cut with a sharp construction knife. In this way, it is possible to get an even line of the ceiling. Similarly, for this technology, you need to cut a line on the floor. It should be left about 6 mm so that you can make a bend on the skirting strip.
