Do I need to putty walls before gluing wallpaper

One common question that comes up when getting ready to decorate your house is if you need to putty the walls before you can apply wallpaper. Although it’s sometimes missed, this step has a big impact on how your wallpaper looks and how long it lasts. Gaining knowledge about putty wall application and when to use it will help you finish projects smoother and more expertly.

To create a smooth base, puttying walls entails filling in holes, cracks, and uneven surfaces. This procedure not only makes your wallpaper look better, but it also makes it stick to the wall more securely. Puttying is crucial for a long-lasting finish because uneven walls can cause bubbles, creases, and peeling wallpaper over time.

Whether puttying is required or not will mostly depend on the state of your walls. Putty is a handy tool for removing small imperfections that are frequently present in newly constructed areas. On the other hand, older homes might have more serious problems like paint chips or cracks that call for careful preparation.

It will be easier and more successful to apply wallpaper if you take the time to properly prepare your walls. Clean canvases such as smooth walls make it easier for wallpaper to stick evenly and lower the possibility of future issues. In the end, taking this preliminary step can save you time and effort and result in a finish that looks more polished and professional.

Question:	Do I need to putty walls before gluing wallpaper?
Answer:	Yes, it"s recommended to putty walls before wallpapering to ensure a smooth surface and better adhesion.

Why putty the walls

Many who had to perform their own repairs are certain that removing the outdated wallpaper is sufficient for the initial prep. When the walls are exactly even, this can be sufficient at times. Since this rarely occurs, it is best to learn how to correctly place the walls beneath the wallpaper yourself.

When the old layers are removed, you frequently find:

• Uneven surface with holes from shelves and cornices;
• Defects, cracks and cracks at the junction of plates;
• Wooden beams with a rough texture;
• Holes in the walls at the output of communications and heating pipes;
• Building materials of a contrasting color that shine through under photo wallpaper or thin rolls for painting;
• Mattering the old putty under the wallpaper.

Small issues can be resolved quickly and easily with your hands and the putty walls underneath the wallpaper. Plasticity makes it simple to seal the fissures, giving contemporary cladding a smooth surface. Because of the way the walls curve in this instance, we can anticipate that they won’t scatter at the joints. If the entire space is covered in pricey wallpaper and, once it has dried, has large, gaping dents from being overly careless, it will be unpleasant.

You don’t always need to examine walls in great detail, like with "liquid wallpaper." Their unique texture allows them to partially conceal flaws. But even small imperfections will show through thin paper photo wallpaper.

You must prepare a quick-drying gypsum composition in order to remove defects. Significant variations in terminology are related to polymer-based or cement compositions. Particularly obvious are the uneven levels of the concrete ceilings and the chips and potholes in the outer angles. Putty must therefore be placed underneath smooth wallpaper made of thin materials.

Types of putty mixtures

There are various steps involved in leveling a wall. If these are concrete slabs from urban construction, flaws are found by filling in cracks and strengthening cement mortar after the old wallpaper is removed. Usually, a careful examination of the surface is necessary, and there are two methods for applying wallpaper to walls that you can do by hand.

The base, or starting mixture, has a coarse-grained composition with good adhesion and is full of defects and seams. No more than 5 mm should be present in the leveling layer. You are not going to get an absolutely smooth surface at this point. When egregious imperfections are concealed, they use their own hands to apply the wall’s finish plaster beneath the wallpaper to finish the job. It is necessary to dilute the flour-like powder with water until it has the consistency of sour cream.

Finished putty is frequently offered for sale in a plastic container. The plastic mass is slightly shiny, kneads easily, and does not stick to the hands. It has a uniform thickness of 1.5–2 mm.

In order to clean laminated wallpaper in a high-humidity room, a moisture-resistant mixture must be applied to the wall beforehand. It’s critical to make sure the floor and walls are properly waterproofed and to install the baseboard after the roll materials have been glued together.

The kind of base varies among sapthary compositions:

• Cement
• Latex;
• Acrylic;
• Silicone;
• Oil-cell.

Small batches of the polymer mixture are prepared over the course of two hours of labor. After making the solution, it hardens in three to four hours, making the remaining putty unsuitable.

Material consumption, how to calculate

Clarify the use of a dry mixture and finished paste before purchasing putty for uneven walls and adhering wallpaper. It is advised to "bother" with the front of the room’s work. The instructions specify the rates of consumption. Occasionally, recommendations written in a language that is difficult to understand are misplaced during transit. Next, they address general conventions.

Skilled experts understand that a layer of 1 mm requires approximately 1-1.5 kg of a mixture spread over 1 m2. Depending on the ingredients and preparation technique, this standard varies.

The putty application technique, the surface type, and the master’s experience all affect consumption. Compared to a smooth surface coated with primer, the rough wall "eats" the mixture considerably more. The base is not always required. To appropriately place the walls beneath the wallpaper and make a small savings, the masters in this instance favor a universal composition.

Large fraction mixtures imply higher consumption than standard calculations show. But when wallpaper is being applied to a brick or stone wall, it is impossible to skip the foundational layer. Since dry starting putty is sold in paper bags weighing several kilograms, it is necessary to round up the consumption. One kilogramme per square meter is the minimum.

Double the consumption rate under the painting grid, which is shed into putty. For the purpose of leveling the walls during the shrinkage of the house, you will require a thick layer, up to 5-8 kg of base for each square. The bulges can be sealed, which will simplify alignment and reduce material consumption.

The "Ceresit CT 29" starting mixture instructions show a lot of variability: one layer can be anywhere between 2 and 20 mm in thickness, and the thick layer’s consumption increases several times.

How to properly put putty on the walls

Plaster cannot be "trampled" with a thick layer applied in one application because as it dries, it will crack. For each type of base, there are different acceptable minimum and maximum layers. The instructions on how to manually install the wallpaper on the walls indicate this. Dry coating is applied to each layer of material.

Important prerequisites for applying wallpaper to walls by hand:

• Optimum temperature and humidity of the room;
• High -quality kneading;
• Primer of walls;
• Distribution of mass with thin layers using a tool;
• Coating in 2-3 layers with a smooth surface at the finish stage.

Avoiding drafts is crucial when drying out layers. There’s no way to open doors or windows to let fresh air into the room. Low temperatures—between 8 and 12 °C—are preferable to heat and dry air because they will rapidly "pull out" all of the moisture from the walls. It is preferable to switch off heating appliances.

Surface preparation

Remove the previous layer from the gluing rolls, the old paint, and the laying plaster before placing the wallpaper on the walls.

• It is easier to remove the paper after thoroughly soaked with a spongy roller or spray;
• To remove paint, you need a “wash” and a hair dryer;
• Placing plaster is cleaned with a sharp spatula and a metal brush;
• A thick layer of building materials and cement on the seams of brickwork are knocked down with a chisel.

If you choose to do repairs yourself, they advise getting a new set of spatulas with varying widths. Together with them, you’ll need:

• Electric drill and a container for kneading dry putty;
• A plumb line (for checking a vertical) or a universal level with a “laser” (horizontal);
• Grinder (large sandpaper or grater-net) for final study;
• Foam roller (for wetting the old layer);
• Vacuum cleaner (dust removal from grinding);
• A wide rule, from the word "edit" (distribution of putty on the surface);
• Brush and roller for primer;
• Water containers where brushes are excited after work.

If a good tool for wall placement has a surface with bent angles and zabin, traces will still be visible.

In order to prevent the tool from drying out, it is preferable to remove the remaining mass from it right away.

Work with starting putty

As it happens, the old wallpaper has been very carefully glued. Despite what newcomers believe, they shouldn’t be used as a foundation. During pasting, the paper layer will quickly wrinkle and exfoliate with the new wallpaper.

There should not be any lumps in the initial mixture. If the cement mixture for seam sealing is being prepared separately, it is advised to use small river sand and a white sequence. With this composition, learning how to putty walls is simpler than using a spatula to stuff your hand.

Setting up dry putty for a job:

• Pour a small portion of dry matter into a container for kneading;
• The volume of water should coincide by the proportion indicated in the recommendation on the package;
• It is better to stir not manually, but mechanically (if there is no construction mixers, an electric drill with a “mixer” is suitable);
• It is better to add water to dry putty in portions, thoroughly stirring until there are lumps.

A ready-made mixture of collision is collected with a narrow spatula and placed on a wide rule (tool). Starting from the corner, the mass is smeared with self-assured gestures along a small portion of the wall. Depending on the temperature, the wall needs to dry for 12 to 24 hours before applying again.

The finish putty

The alignment of the finish is the last step in priming walls for wallpaper application. The technology used to apply the basic coating and the preparation of the composition and application are not all that dissimilar. It is advised that the layer be no thicker than 1.5–2 mm.

They make an extensive study under thin wallpapers. Without putty, every flaw in the walls and the joints made of various materials is apparent. There will be exposed wood beams, a metal corner, and gray reinforcement. As such, they require finishing putty, either general purpose or specialty.

For concrete walls, primer, starting, and finish putty should ideally be purchased from a single manufacturer’s brand. This ensures superior coating quality and outstanding adhesion.

You can finish the work whenever you want without worrying that the remaining portion will dry out if you use a plastic finish mixture in a plastic container. It is imperative that the packaging specifies the shelf life and storage conditions that should not be disregarded.

What to do after the finish putty: grout

If there are no flaws, the base layer application can finish the alignment procedure. Guttering evenly beneath textured wallpaper doesn’t always need to be done. The performance is fragmented, revealing bumps along the way.

Under the fiberglass roll lining, high-quality wallpaper paste is sufficient for painting. In other situations, it is advised to thoroughly clean the walls.

Using a specialized tool, grouting smoothes the surface:

• Fine -grained sandpaper;
• Grinding grid;
• Bar for grouting;
• Grinding.

Stripes left by the tool are common when working with starting putty, especially for novices. During grinding, they are eliminated. After this step is finished, the wall is carefully vacuumed beneath the primer and trellis glue.

Puttying brick surfaces

Brick masonry is unique due to its heterogeneity, hidden seams, and potential vertical deviations. It is crucial to use a plumb line to ensure that the wall is flat. If there are no issues, working will be simpler and material consumption will be at a minimum. Beacons are used for alignment with large deviations.

In any case, in an affordable wallpaper putty: to make the masonry level:

• Polymer;
• Cement;
• Gypsum.

Select a type that satisfies the functional specifications. Purchasing the priciest composition makes no sense if there is a multi-layer alignment.

The masonry itself has a high adhesion, but the cement that sticks out at the seams needs to be broken off or beat off. Following surface preparation, a working solution is made and applied to the wall. The technology used to apply the final layer of wallpaper to walls by hand is the same as that used to work on any other surface.

How to put the concrete walls correctly

Old coatings can be removed in a variety of ways, exposing wall imperfections that require repair. They "appear" after costly repairs are finished. First, align, then close the gaps. But in an apartment in the city, is it really necessary to putty even walls before gluing wallpaper?

Modern wallpapers should not be glued to "naked" concrete without a plaster layer, according to experts. All of the glue’s moisture will be swiftly absorbed by cement, causing bulky vinyl rolls to easily come off.

Putty compounds are applied to concrete slabs using cement as a base. Other compositions can be used at the "finish." It is recommended to apply two coats of primer to dry concrete. Nobody can promise that without further surface preparation, the wallpaper won’t crawl. By using the household spray gun to moisten the walls, you can take a chance. Moisturizing is not necessary after primer.

Puttying the walls is a necessary step to guarantee a level, smooth surface before applying wallpaper. Puttying creates a perfect base for the wallpaper to stick to by sealing any gaps, cracks, or flaws. This process not only makes the wallpaper look better in the end but also makes it more durable by keeping it from peeling or displaying flaws over time. The putty is an essential step in the wallpapering process because skipping it can result in noticeable defects and a less polished finish.

Gypsum cardboard put on wallpaper

Plywood, GKL, and other sheet materials are occasionally used to make the components and partitions. It will be very annoying if the joints between the drywall sheets show through the expensive wallpaper that has been glued on.

The primary purpose of drywall putty is to conceal uneven joints. GKL is a uniform, smooth material. Using reinforcement from a plane grid, putty can conceal design flaws that are fairly flimsy in nature. Cutting off turning joints and deepening self-tapping screws are necessary. Once the flaws have been removed, the finished composition can be puttied onto an acrylic or gypsum foundation.

How to put up wooden surfaces

Wood is a living substance that can deteriorate. It is necessary to select highly specialized and universal compositions that maintain some flexibility when selecting a mixture for wood.

In rooms with particular requirements, it’s crucial to select the suggested marking:

• KR standard – ordinary conditions;
• LR standard is used for places with high humidity.

Because of their elasticity, polymer compositions are perfect for the "living" building material. The compositions of reliable manufacturers are reliable.

• VGT (acrylic putty for wood);
• Eurocol;
• Eurofiller Wood Plus;
• Tikkurila Lakkakitti;
• Eurotex (acrylic);
• Knauf Polymer Finish.

Old wooden surfaces, beams, partitions, and attic floors are all painted with putty. Wood-derived materials are used in the design of certain architectural and designer forms. Under the wallpaper, they are additionally coated with a specific primer.

When you can start pasting?

You can begin gluing wallpaper after the necessary priming and grinding. Waterproofing and applying fungicide (a solution made from mold and fungus) to problem areas are recommended for homes with "raw" corners. Prior to the last stage of repair, it is crucial that every layer thoroughly drys out for three to five days.

In the absence of a primer layer, the base layer will absorb a lot of moisture. Thus, there may be unpleasant "surprises" when gluing. It is not necessary to impregnate the walls with glue for all types of wallpaper; this is especially true for non-woven or fiberglass options. It is sufficient to apply just the initial leveling layer and soak with a primer to create "liquid" wallpaper.

For many do-it-yourselfers, the question of whether or not to putty walls before wallpapering is a frequent one. The choice is primarily influenced by the kind of wallpaper you want to use and the state of your walls.

You might be able to avoid puttying entirely if your walls are relatively smooth and defect-free. To guarantee a smooth and perfect finish, puttying the walls is advised if there are any obvious cracks, holes, or uneven surfaces.

In order to prevent the wallpaper from sticking to any blemishes or irregularities, puttying walls before wallpapering can help create a uniform surface. This can make the finished product appear more polished and extend the life of your wallpaper.

Putty on the walls also gives you the opportunity to fix any underlying problems, like water damage or structural cracks, which over time can erode the integrity of your wallpaper. You can guarantee that your wallpaper will continue to look great for many years to come by taking care of these problems in advance.

In conclusion, applying putty to your walls before applying wallpaper can significantly enhance the final product’s durability and overall appearance, even though it might seem like an extra step. Take some time to evaluate the state of your walls and determine if puttying is required to get the best results.
