Pasting walls with wallpaper, types and calculation of the required amount of materials, choice of glue, preparation of walls, gluing technology and its nuances. Pasting walls with wallpaper is a type of interior decoration. With the help of this roll material, you can create a stylish and attractive interior. All that is needed for this is to prepare the surface, choose the type of coating and perform the work in compliance with the technology.
The main varieties of wall wallpaper
For pasting walls with wallpaper with your own hands, you can use a variety of types of this material. When choosing it, one should take into account the features that the future coating should have, for example, the ability to hide small wall defects or be resistant to moisture.
Paper wallpaper for walls
They are the most popular, the prices for such wallpapers are different, but not high. Manufacturers produce single-layer simplex materials and duplex materials that have two layers. There are smooth wallpapers with embossing and relief.
Their advantages are affordable prices, simple pasting and a large assortment, and their disadvantages are average quality, low wear resistance and resistance to moisture.
Non-woven wallpaper on the walls
This is a relatively "young" type of wallpaper. And although it appeared not so long ago, it has already managed to take its rightful place in the construction market. The material has all the necessary qualities to create a cozy and effective interior.
The list of advantages of non-woven canvases includes: relatively low price, the ability to mask small flaws in the walls and paint surfaces up to 4-5 times. The wallpaper is hygroscopic, therefore it does not disturb the air circulation in the premises. This eliminates the appearance of condensation on the walls.
The disadvantages of such wallpapers are their limited pattern and satisfactory insulating properties.
Vinyl Wall Wallpaper
These wallpapers have significant durability, their service life can exceed 15 years. Often vinyl canvases have a non-woven base, that is, such a material concentrates the best qualities of both types of products.
Vinyl has a very attractive look, it often imitates any texture, from textiles to natural wood or stone. There are types of vinyl wallcoverings that can be painted over.
The advantages of the material are high strength, good water resistance and antibacterial properties. Its disadvantages are its high weight, depending on the thickness of the web, high cost and low hygroscopicity. The first time after pasting the walls with vinyl wallpaper, an unpleasant odor may be present in the room.
The work of installing wallpaper is not particularly difficult, but before doing it, you should pay special attention to the preparation of the walls and the choice of glue that matches the type of canvases.
Calculating the number of wallpaper for the walls
Calculating the right amount of wallpaper for pasting the walls of a room is a serious business. The easiest option is to use a special program for calculating the number of rolls. A calculator like this can be found on many construction sites. Self-calculation should begin with determining the size of the room.
The calculation of wall wallpaper along the perimeter is carried out as follows:
- First you need to measure the perimeter of the room and the height of the walls. For example, let's take a 6x3 m room. Its perimeter will be 18 rm. If the walls are not planned to be glued up to the ceiling, the calculation is based on its actual height.
- To calculate the number of sheets of one roll, its footage should be divided by the value of the gluing height. For example, the height of the room is 2.5 m, the roll footage is 10 m. Then it will be enough for four lanes: 10/2, 5 = 4. With a pasting height of 2, 7 m, it turns out: 10/2, 7 = 3, 7. That is, the roll is enough for three canvases of 2, 7 m, and 0, 7 of its footage still remains. To determine the length of the remainder, you need to multiply the value of 0.7 by the height of the pasting: 0.7x2, 7 = 1.89 m. This piece can be used for pasting walls behind heating radiators, above windows or doors.
- The required number of canvases is determined by dividing the perimeter of the room by the width of the roll, which is usually 0.53 m. By simple calculations, it turns out: 18/0, 53 = 33, 9. If this figure is rounded to an integer value, it turns out that the room will need 34 canvases of wallpaper.
- The number of wallpaper rolls is calculated by dividing the total number of canvases for a room by their number in one roll. With a pasting height of 2.5 m, it comes out: 34/4 = 8.5 rolls. For a gluing height of 2, 7 m, the calculation is the same: 34/3 = 11, 3. When these values are rounded, we obtain 9 and 12 rolls, respectively.
- This calculation does not take into account the area of window and door openings. If they are large, then their width can be subtracted from the perimeter of the room and the number of wallpapers can be calculated using the new values. However, you should take into account the need to have a stock of wallpaper for emergencies.
Features of calculating the amount of material by area:
- With a room area of 3x6 = 18m2 its perimeter is 3 + 3 + 6 + 6 = 18 r.m. If you multiply the perimeter value by the pasting height, you can get the total area of all wallpaper canvases. For example, with H = 2.5 m it comes out: 2.5x18 = 45 m2.
- The area of the unfolded roll of wallpaper is: 10x0.53 = 5.3m2, that is, one roll is enough for pasting 5 m2 walls. The remainder does not need to be taken into account.
- To calculate the number of rolls, the value of the wall area is 45 m2 must be divided by the area of the unfolded roll: 45/5 = 9. As in the previous calculation for the perimeter, the total is 9 rolls.
Wallpaper with geometric patterns or ornate patterns requires maintaining the integrity of the print when applied. In such cases, you need to take into account the rapport - the distance between periodically repeating elements. The rapport is indicated, like other wallpaper sizes, in the instructions for the product.
When pasting walls with wallpaper with a pattern, the consumption of material is always higher than usual. The rule is one: a larger rapport increases the waste of the canvases when they are fitted to the pattern. This factor should be considered when purchasing material. For stock, it is recommended to purchase an extra roll in case of an error in the work.
Important! Rolls of wallpaper should always be purchased from the same shipment. Otherwise, the shades of the patterns of the canvases of different rolls may differ.
The choice of glue for wall wallpaper
For high-quality work, it is necessary to observe not only the technology of wallpapering the walls, but also to make the correct selection of glue. Despite the variety of its types presented on the construction market, you need to buy a composition designed for a specific type of roll material.
For paper wallpaper, the lowest price glue is suitable, but of sufficient quality to provide reliable and easy pasting.
Fabric, vinyl and embossed wallpapers require an adhesive mixture on vinyl components for installation. The peculiarity of this composition lies in the fact that the coating sheet can be re-glued without much difficulty if it was installed incorrectly.
If necessary, this should be done while the glue mixture is fresh, but there is usually enough time to correct the error. It is not recommended to buy quick-drying compositions; with their use, the quality of pasting may deteriorate.
For pasting walls with non-woven wallpaper, a special composition is required, which is applied not to the canvas, but to the wall. There is no need to wait for the surface to be impregnated with glue, the wallpaper is glued immediately after the surface is smeared.
Adhesive for heavy textile and velor wallpaper is a special kind of similar mixtures, it must withstand the weight of the material.
It is recommended to use universal types of adhesives only in extreme cases. Such compositions are diluted with water to a concentration depending on the type of wallpaper. The universal glue is great for mounting light paper wallpapers, in all other cases it is recommended to buy a special mixture.
Preparing walls for wallpapering
The preparation of the walls is of decisive importance for obtaining a high-quality result of their further pasting. First, you need to remove the old coating, inspect the walls and, if necessary, level them, having previously repaired the potholes and cracks.
To work, you need to stock up on such materials and tools: wallpaper, glue and a container for its cultivation, a drill with a mixer nozzle, a roller, a primer and a brush, a sharp knife, a metal ruler, a building level and a tape measure, a spatula, a plumb line and a roller for rolling edges.
Apartments in new buildings are often bought without decoration at all. This greatly simplifies the task of preparing the walls for wallpapering, although it requires a lot of time and money. To give the concrete surface some roughness, which is necessary for successful further work, the walls should be plastered:
- At the first stage of work, you need to knead the plaster solution to the consistency of thick sour cream and spray it with a layer of 3-9 mm on the walls using a special painting tool "falcon". In this case, all irregularities should be filled.
- After the surface has dried, it is required to apply a primer plaster layer up to 6 mm thick. It can be applied in 2-3 times.
- The final covering layer of plaster is applied after priming. Its thickness should be 2-4 mm. In this case, the building mixture is mixed with less water than when spraying the solution in the previous case.
- After plastering, the walls should be carefully trowelled to compact and level the surface, and then sandpaper.
To remove old wallpaper, you need to work carefully so as not to damage the surface of the walls before gluing the new material:
- You will need a metal spatula, clean water, detergent or vinegar, and a spray bottle to clean the walls.
- The surface of the wallpaper must be moistened with a solution of water, vinegar or a household chemical. It is convenient to use a spray for this purpose.
- Further work must be done with a spatula, carefully removing the soaked wallpaper with it, trying not to damage the surface of the walls.
- After removing all traces of the old coating, you need to inspect the cleaned surface. If it is flat, you just need to sand the walls.
- In the presence of defects, the walls will have to be leveled with a starting coarse-grained gypsum solution.
On the surface of walls covered with paint, the pasted wallpaper will not adhere well. Therefore, it is important to clean them completely, and not to make cuts on the old coating, which will not bring the desired result. You can remove paint from walls in the following ways:
- Construction hairdryer … This is a long and difficult job requiring a respirator and periodic ventilation of the room.
- Angle grinder "Bulgarian" … She will quickly remove the paint, but this work is very dusty, you will have to close the doors tightly and plug the cracks with a rag.
- Special paint removers … This is the most suitable option. The surface of the wall is not damaged during such cleaning, the old coating layer is easily removed. Before working with the wash, you should protect your eyes, hands and respiratory organs with special glasses, gloves and a respirator.
After cleaning the walls from paint, they need to be putty and covered with a layer of penetrating primer. If it is not possible to remove all the paint, the surface can be covered with Betonkontakt mortar or glue diluted with water, intended for vinyl wallpaper, although this is not the best option. In this case, the new wallpaper will not last long on the wall.
Before gluing the wallpaper, the walls must be primed taking into account the type of finishing material. In many cases it is indispensable as an intermediate layer to increase the adhesion of glue and plaster.
Marking the surface of the walls before wallpapering
After finishing the preparation of the walls, you can mark them for the correct placement of the canvases. For this purpose, you should use a plumb line, chalk and a long metal ruler. The markup starts from the window with a gradual movement to the left along the perimeter of the room.
The first strip of wallpaper must be aligned with the edge of the window opening. At this point, it is worth drawing the first vertical marking line along the wall. Further movement is carried out taking into account the width of the canvas, two centimeters of the reserve distance and finishing of the corners towards the front door.
In general, the markup scheme looks like this:
- From the window to the left, the markings should be carried out to the corner of the wall on which the doorway is located. It is recommended to number the marked areas.
- Further marking is carried out to the right side of the window opening and continues to the door in the same way.
Wallpaper pasting technology
It depends on the type of wallpaper selected and includes two methods of sticking them: end-to-end and overlap. The first method of pasting walls with wallpaper is modern and provides for the alignment of adjacent strips with edges. When using the second method, the canvases are alternately superimposed with edges on top of each other with a distance of 1-1.5 cm.
The work on the continuous pasting of the walls must be performed in the following order:
- Free the room's floor surface of anything that might interfere with the process and cover it with clean plastic wrap.
- Dilute the glue with water in the proportion indicated on its packaging and mix thoroughly.
- Brush on the back of the canvases or walls, depending on the type of wallpaper.
- Lay the canvases with the sides greased with glue to each other for impregnation for 1, 5-2 minutes.
- You need to start pasting the walls strictly according to the scheme. In this case, the folded canvas should be applied to the top of the wall and carefully straightened in an upright position, smoothing it from the front side.
- The work should be done with a rubber roller or clean rags from the center of the canvas diagonally downward, removing air bubbles and leaving no folds.
When gluing the wallpaper back to back, all excess material should be immediately removed with a sharp knife. The wallpaper should also be trimmed near the floor or baseboard. In the process of pasting, it is necessary to monitor the even arrangement of the canvases on the walls, the absence of gaps and bubbles. The sections of the walls located above the openings and behind the heating radiators should be pasted over last.
Special attention should be paid to wallpapering the corners of the walls. There are several rules for her:
- The canvases in the corners must be joined so that they do not start on any surface of the walls by more than 4-5 cm.
- The next canvas must be glued with an overlap of the remaining 4-5 centimeters.
- All corner joints of the canvases should be additionally coated with glue and rolled with a special roller for a tighter pressing against the wall.
Important! Wallpapering the walls should be done in the absence of a draft in the room. You cannot ventilate it for 12-24 hours, wait until the material is completely dry.
Useful tips for wallpapering your walls
There are some nuances of working with wallpaper that should be considered in order to achieve the best result:
- Before pasting the walls, it is recommended to de-energize the room and remove the covers of all sockets and switches. Holes for them should be cut immediately after the application of the canvas, and do not wait until it dries.
- To make the walls covered with wallpaper look neat, you must first dismantle the skirting boards. This will allow you to glue the wallpaper to the floor, and after installing the skirting boards in their rightful place, there will be no gaps and joints.
- The wall along the perimeter of the doorway should be well coated with glue and carefully put the edges of the canvases behind the platbands with a spatula. Any excess glue must be removed immediately with a clean cloth.
- Paper wallpaper should first be cut into canvases, coated with glue and folded back to back for 10 minutes. After impregnation, the canvases will stop bending. It is also recommended to cover the walls with glue, paying attention to the places of the wall joints. It is better to glue paper wallpapers with an overlap.
- Correct pasting of walls with vinyl wallpaper is carried out on a primer layer. The glue should be applied to the structure and wait a couple of minutes, after which the material should be butt-glued. Vinyl wallpaper is prone to stretching, so you need to work with it carefully. Some types of such material require an additional adhesive layer to be applied to the panel.
- Non-woven wallpaper should only be glued onto a clean surface covered with putty. On the walls, you need to generously apply an adhesive composition and install such wallpaper end-to-end, removing bubbles and folds by smoothing the material with a rag or roller.
