Finishing work

Before wallpapering

Wallpaper is glued to a previously plastered surface or drywall. Never experiment with pasting new wallpapers over old ones. In the case of a painted surface, it is enough to simply wash the walls. A porous or unpainted surface must be treated with wallpaper glue; without such a procedure, it will be difficult for the wallpaper panel to move along the wall, which will affect the alignment of the pattern. Before directly applying the wallpaper, the glue on the wall must dry.

Before gluing the wallpaper, the walls must be leveled and primed. You can read about how to quickly remove old wallpaper here..

Sanding, priming and filler

Room layout

It is recommended to start gluing from the corner – this helps to hide pattern defects in case of poor alignment of panels that are glued first and last. If the room has some kind of architecture (arch or fireplace), and the wallpaper has a rather large pattern, then the first panel must be glued with a pattern along the axis of the architectural element. Other panels are glued on both sides of the original. Having decided on the starting point, in the future you can use the roll in the form of a template for marking the position of the panels on the surface. Thus, you can determine the location of the joints in inconvenient places and, if necessary, change the starting point..

Preparation for pasting wallpaper

If you have not experienced a similar procedure before and «do not want to break the wood», then it is better to use wallpaper with an arbitrary pattern. This will help you focus on the technique and not on the alignment of the drawing. By the way, for beginners, it is better to use a wallpaper with a ready-made glue layer..

The work begins with determining the direction of the pattern. It can be seen on the roll by the corresponding arrow, which indicates the flow.

Cutting wallpaper with a pattern

To begin with, let’s figure out the nature of the pattern on the wallpaper, because the pattern can be either symmetrical or asymmetrical with respect to the axis of the canvas. This also matters when calculating the number of rolls. The length between the repeating wallpaper pattern is called the rapport or simply the pattern pitch. The step length can vary from 5 to 30 cm.The longer the step length, the more difficult it is to adjust the pattern and, accordingly, there will be more waste.

It is necessary to measure the height of the wall and add 10-15 cm from each end to fit, then unfold the roll and arrange the panels. If the workplace has the required dimensions, then it can be used as a template. First you need to cut off the panel with a small gap of 50 mm. The drawing on the second canvas must be combined with the drawing on the first one. At the workplace, you can note the length of the panels and the placement of the pattern for odd and even panels. Horizontally identical wallpaper with a pattern on opposite edges has matching halves of patterns. Different horizontally wallpaper on opposite edges of the matching halves of the patterns are often shifted by half a step from the pattern (see the picture).

How to choose wallpaper glue

Successful gluing largely depends on the correct selection and application of the adhesive. First of all, when buying wallpaper, always pay attention to the manufacturer’s instructions for using the adhesive. If there are none, then you can ask in the special. store or seller. It is imperative to determine whether or not a fungicide-added adhesive should be used. Such an adhesive mixture prevents the formation of mold, therefore it is used when gluing washable or vinyl (waterproof) wallpaper. The package indicates the type of glue and material consumption for the number of wallpaper.

Organic and synthetic adhesive mixtures are available in both solid and liquid form. The solution is prepared by slowly pouring out the contents of the bag and mixing it with the required amount of water. To prevent various lumps, the solution must be continuously stirred, and then allowed to thicken and settle (the required time is indicated by the manufacturer). The glue is able to store its properties for about one week, but at the same time it must be kept in an airtight container..

Liquid glue is immediately poured into the container and used in work.

Glue application

First, you need to spread the panels on the working surface with the pattern down. Then we apply glue to the middle of the panel and smear it on the sides with a brush. Pay special attention to the edges. If glue gets on the floor, it is better to wipe it off immediately with a damp cloth. Have you smeared the canvases? Great, now we fold them with glue inward. This procedure will facilitate transfer to the wall and prevent drying out. If necessary, you can fold the panel again..

Wallpaper stripes

All wallpapers, except for very thin ones, must be left for impregnation: 2-3 minutes for less dense ones, and up to 15 for more dense ones. The duration is usually written in the instructions on the package. Wallpaper impregnated with glue will prevent the appearance of bubbles and soften them, which simplifies the immediate process of pasting. Therefore, it is better to put aside the cloth smeared with glue and start processing another. When working, it is necessary to be careful not to get glue on the front part and the workplace on which the next roll will lie. To do this, you can put several layers of paper on the desktop and remove them as the wallpaper is processed. By the way, we answer your future question: «no, the newspaper cannot be used, otherwise the newspaper paint will add its part of the decor to your wallpaper».
