Adding color and texture to any room with pasted wallpaper can be a great way to give your house a unique touch. Despite its apparent simplicity, there are crucial actions and factors to take into account in order to guarantee a seamless and expert completion. Is putty necessary when applying wallpaper directly to plaster walls? This is one of the most frequently asked questions.
Although plaster walls provide a strong and level surface for wallpaper, they frequently have flaws like tiny cracks or uneven textures. The entire appearance of the wallpaper may be impacted by these imperfections. Usually, putty is used to smooth out these flaws and create a perfect foundation for wallpaper. However, depending on the state of your plaster walls and the wallpaper you select, you can still get good results without using putty.
It may be possible to avoid puttying if your plaster walls are in good shape and have few flaws. Thick, high-quality wallpaper, particularly one with patterns or textures, can help cover up small imperfections. It can also be easier to achieve a professional finish without putty by using a wallpaper liner, which is a special paper that is applied to the wall before the wallpaper, to add an extra layer of smoothness.
The plaster surface needs to be carefully prepared if you want a more simplified process. Using an appropriate primer and giving the walls a thorough cleaning to get rid of dust and debris will help the wallpaper stick better and last longer. Even if you decide not to use putty, taking the time to properly prepare can have a big impact on the result.
Whether or not to use putty ultimately comes down to the desired effect and state of your wall. You can successfully wallpaper plaster walls and take pleasure in a beautifully decorated space with the correct planning and supplies.

Is plaster suitable for gluing
- Cement plaster. The material in a diluted form has a heterogeneous granular structure. After application and hardening, the plaster acquires a rough, tuberous surface. If you attach wallpaper without putty, especially thin ones, then through them all the shortcomings of the uneven base will be visible. In addition, a dark mixture. Because of this, the appearance of the wallpaper may deteriorate. The plaster mixture will simply be visible through thin wallpapers, especially if the canvases are translucent. Cement mixtures are also able to absorb moisture. When applying wallpaper glue, moisture from it can quickly absorb into the plaster, which will lead to poor gluing quality. After getting wet, the plaster is unevenly darkened, covered with spots throughout the wet area. A mixture of this type is often used in new buildings.
- Gypsum plaster.The solution also has the properties to absorption of moisture. Therefore, the wallpaper is recorded on the surface not in the best way. And after time they will completely exfoliate, completely fall off. Often the surface of the gypsum is flat and close to smooth. Therefore, it is not necessary to align the surface especially. It is only necessary to process the gypsum base with a primer.
- Decorative plaster.The material is designed to create a finish coating. Not intended for fastening on top of other departments. You can’t even try to glue trellises if the decorative mixture forms a relief surface after drying. Thick wallpaper on a non -woven or vinyl base will not be able to hide the relief of the finish.
It is obviously preferable to avoid starting the wallpaper without putty if the outcome is required to achieve the desired, precisely even finish.
In the event that putty is not used, the following issues could occur:
- Plaster tends to crack over time. Voids are formed, which lead to detachment of paintings and even tears, if the discrepancies are large.
- Thin canvases will shine through the black material, which will distort the general appearance of the finish.
In this instance, gypsum plaster is the most appropriate. After processing, the surface is level, and priming is required to ensure that the wallpaper is securely attached to the long, hardened plaster. This is the process that reduces the absorption of liquid.
When and how to stick wallpaper on plaster
Certain building material manufacturers state in their mixture description that additional putty is not necessary for their plaster. Such a statement is partially accurate. Putty should be used in the work before gluing, though, as the plaster coating is not a finish layer.
You can glue the wallpaper without putty if you don’t need an exact finish. There won’t be a flawless and long-lasting outcome. However, there’s a window of opportunity for the finish.
Utilize the following algorithm to adhere the canvases to the plaster:
- As thoroughly leve the surface as possible. On a special holder or bar, fix the sandpaper. Start rolling out until the surface becomes as smooth as possible compared to what was originally.
- Process a wall with a deep penetration primer in order to fill the existing pores, make a strengthening. Wait for the mixture. Sometimes they can recommend a few primer. But as practice shows, there is no significantly improvement from reusable impregnation of the base. But the consumption of the mixture, which means that the cost of the soil also increases.
- Mix the wallpaper glue, apply to the wall. Wait for drying, then you can stick.
Sometimes the surface needs to be further smoothed with liquid plaster before the sandpaper is cleaned. Usually, when the first layer was applied to the rule, this kind of work was necessary. Then, after solidification, the surface is not perfectly level. Prior to cleaning and applying soil, any irregularities must be smoothed out.
For smoothing, a small amount of plastering solution is ready. Since the mixture is consumed in small amounts, there is no need to knead it thoroughly. The consistency should be like thick sour cream. The mixing is done in a different container.
You will also need two spatulas for the task—one small and one large. Plaster is applied to a wide spatula or straight onto the wall using the first tool. To spread the mixture across the surface, a second is required.
A "skin" must be used to remove any obvious protruding irregularities from the wall first. Additionally, you are in line with plaster’s need for this location.
At the processing sites, you repeat the process after waiting for the required amount of time for hardening. so that the bumps are finally gone.
You cannot focus on tiny holes or hollows that are no larger than two to three millimeters. Such flaws won’t impact the finish’s outcome.
Advantages and disadvantages of gluing for plaster
- No need to spend money on the purchase of putty.
- Reducing the repair time due to the absence of a statch stage, but the need to have a high -quality surface is important.
- Visual defects of black decoration are possible, so it is advisable to prepare the wall, and also not choose thin, light, transparent wallpaper for gluing for gluing. The best option would be textured thick dark materials.
- The plastered wall should be originally flat, otherwise there is a need for additional smoothing.
- You have to use a lot of primers to lower the absorption.
Repair work
A detailed tutorial on how to overlap the wallpaper can be found below. In other words, the décor is already present, but it needs to be updated because it is outdated.
You will need these supplies and instruments for work:
- putty;
- plaster;
- The primer is deeply permanent;
- wallpaper adhesive mixture;
- level or plumb line;
- container to knead the mixture;
- industrial mixer or ordinary electric drill with a mixer nozzle;
- A set of spatulas – small and large wide;
- roller or painting brushes;
- grater (sandpaper fixed to the holder).
Surface preparation
- Removing old wallpaper or other coating. It is necessary to soak well with water, spraying the liquid from the spray gun, or treating with a wet washcloth. Next, wait a quarter of an hour while the wallpaper is well soaked and soaked. After, deleting the coating will not be difficult. Wallpaper will get into large pieces. Put the canvases with a spatula, then tear off. It is important to remove everything without exception. Even the remaining small pieces can cause bubbles on the new coating. Tiles are removed mechanically using a chisel and a hammer. Oil paint can be removed with a spatula after heat treatment with a construction hairdryer, or washing products.
- Detection of fragile sections of the coating. With a light tapping of the hammer we pass throughout the wall, and especially through visible flaws. Unstable weakly holding elements remove. The emerging cavity inside is smeared with soil, they are waiting for the composition to dry out. Then the missing pieces are covered.
- The wall is cleaned of dust, dirt. Fat spots are eliminated by solvents.
- Metal parts mounted previously (nails, self -tapping screws, dowels, others) are completely removed, the cracks are closed. You can also score elements inside flush with the surface. Or cut off a grinder. It is advisable to additionally paint with ordinary paint all metal objects. Painting is done to prevent corrosive processes.
- If the wall is generally greatly curved, then it is recommended to align. A great option would be the use of the Rotband brand.
- After performing the above actions, the surface is ready for priming. The primer is made two -layer application, each of which is possible only after the previous. In order to reduce the amount of adhesive glue into the surface in the future, a small amount of PVA can be added to the primer. An alternative to the ground can be diluted wallpaper glue.
Putty
- As indicated in the instructions, a plaster mixture is prepared.
- A narrow spatula plaster draws from a container, applied to a wide. You can also immediately place the mixture on the wall.
- By the movement from the bottom up a wide spatula, the solution is distributed along the wall with a uniform thin layer. The surface does not touch to harden.
- The wall is given perfect evenness. Processing is carried out by sandpaper, which is fixed on the bar, or with a special construction grater.The strip is made in circular movements until the wall becomes perfectly even. Unevenness, protrusions left by a spatula should not stay.
Following that, double priming is done. The second primer can only be applied after the first layer has had time to dry.
Wallpaper gluing
- Glue is divorced. There are always proportions and accurate instructions on factory packaging. In stirring, you can use a wooden shoulder blade, but more efficiently apply a drill with a nozzle. The mixture must be thoroughly stirred so that lumps do not form. To do this, the powder is covered with a thin stream in already stirring water without stopping.
- The mass is left to acquire the necessary density and adhesive characteristics. At this time, wall marking is made, stripes of suitable length are cut.
- Marking is made only for the first canvas. The rest of the canvases are attached to the previous one or an overlap. The technology depends on the base of the wallpaper (paper, vinyl or non -woven). With the help of a plumb line or level from the ceiling to the floor, an inconspicuous line is drawn with a pencil. The line will become a reference point. Instead of a solid line, drawing a dashed line is allowed. It is not necessary to put pressure on the pencil, otherwise the graphite can leave black marks on the wallpaper after it is soaked in the gap.
- Measure the height of the wall, preferably for each strip separately, since in some buildings height changes can reach several centimeters. And, which means that the length of each strip can differ significantly. The floor in the room is covered with a clean oilcloth so that the front side of the roll does not get dirty. The rolls are partially unfolded and placed on the floor so that the wrong side looks up. A strip of the required height is measured, plus 10 cm, so that there is an allowance from below and from above 5 cm. The cut is made with scissors along the drawn line, or a knife, having previously banged the strip.
- The strip on the wall is smeared with glue. The processing is subject to part of the wall, which is slightly wider than the strip itself. This is done so that there are no waterproof places. Then the wrong side of the wallpaper is smeared and is left for impregnation for several minutes. In the latter case, the strip is folded in the correct position. Both edges are wrapped inside.
- The wallpaper itself can be attached to both one person and two. The latter option is preferable, since it will turn out to be faster and the risk of incorrect work is minimized.
- Folded in the previous stages and an additional rolled strip is taken by a person. To get out to the ceiling, put a stepladder to the ceiling. A person climbs onto the stairs, unfolds the upper edge of the strip, which begins to be attached from the ceiling, stepping by about 5 cm by the upper corner. Further, the wrap leans along the vertical line against the wall, gradually moving to the floor. In parallel, ironing is made using a sponge or plastic wallpaper spatula. So the formed air cavities are eliminated, glue is expelled. Movements should resemble a Christmas tree.
- Particular attention is paid to the joints. If the glue was applied by an excessive amount, then when ironing it will certainly come from the edges of the canvas. Remove the remains with a damp rag or sponge. Joints are the most vulnerable place, which over time often departs. Therefore, it is recommended to carefully roll the edges with a butt roller.
- Extra pieces that went to the ceiling and floor (or skirting, if it has already been installed) are easily cut off with a clerical knife. The latter, along with a spatula, leans to the place the intersection of the wall with the ceiling, the movement is made at a time.
- The following lanes are glued according to the same instructions.
The wallpaper is overlapped in the corners, and any excess is then cut off. Reinforcing mesh and putty must be aligned if there are curves in the angles or openings around windows and doors.
Door and window openings, sockets, switches, heating radiators, pipe connection locations, and other similar areas are the hardest to glue.
The room is left empty for a while after it has been fully decorated to allow the wallpaper to fully dry. The drying time can vary significantly depending on the variety. The drying process can take a day or a week. The fastest-drying paper. It takes longer for non-woven and fat vinyl.
The primary guideline is to forbid any indoor airflows. Thus, you must shut all of the windows and doors. It is also not permitted to include equipment such as fans, heaters, air conditioners, or similar devices.
Initial finish
In case the apartment is brand-new and only has a rough finish, the circumstances are slightly different. You still need to prepare the wall, but don’t remove the old finish.
There are two possibilities:
- Described above, implies putty. Then apply according to the above instructions, but exclude the points that describe the process of removing the existing finish.
- Opened in the second paragraph of the article, performed without putty. Suppose, but analyzing advantages along with disadvantages, it is better to dwell on the first version.
How to work with liquid wallpaper
Water must be used in order to prepare liquid wallpaper, which, as the article’s opening states, negatively impacts plaster. It is therefore also unnecessary to apply a liquid decor right away to the plastered base. Water-based paint was once used to coat plaster. It is only then that they begin to conclude. Using a textured roller is required to get the required pattern on the freshly coated wall.
Although it can be a quick and easy way to update your walls, pasting wallpaper directly onto plaster has its own set of difficulties. Although the putty step can be skipped, adequate surface preparation is essential to guarantee a smooth and durable finish. This include using an appropriate primer, fixing any holes or cracks in the plaster, and giving it a thorough cleaning. By following these instructions, you can save time and effort while still achieving an excellent wallpaper finish without the need to apply putty.
What about non -woven trellises
Even though non-woven wallpaper is substantially thicker than regular paper, the plaster’s texture will still be visible through it. As a result, glue should be applied after putty.

5 | Hang the wallpaper: Start from the top and smooth it down to avoid bubbles. | |
6 | Trim the excess: Use a knife to trim the excess wallpaper at the edges. | |
7 | Possible without putty? | Yes, but for a smoother finish, putty is recommended. |
It is completely possible to paste wallpaper on plaster surfaces successfully if the proper methods and preparation are used. Though many people think putty is required to achieve a smooth finish, it’s not always required. Making sure the plaster is dry, clean, and devoid of any loose particles is crucial. A primer or sealer can frequently offer the smooth base required for wallpaper application if the plaster is in good condition.
A good primer can help even out the surface of the plaster when dealing with small imperfections or cracks. Patching, however, might be necessary for larger cracks or noticeable surface irregularities. These areas can be filled with lightweight fillers, which requires less work than a complete putty job. By taking this step, you can make sure the wallpaper sticks correctly and looks smooth.
While it can save time and effort, wallpaper directly onto plaster requires careful preparation. To stop moisture from affecting the wallpaper, it is essential to make sure the plaster is properly sealed. Enhancing durability and finish is another benefit of using a premium adhesive made especially for your kind of wallpaper. For optimal results, always adhere to the adhesive and wallpaper manufacturer’s instructions.
In conclusion, if the plaster is properly prepared, putty does not always create the perfect surface for wallpaper. Wallpapering plaster surfaces can be a simple task if the proper preparation, sealing, and materials are used. You can achieve a polished finish that accentuates the beauty of your walls by following these steps.
