Which putty to choose so that the work goes quickly and efficiently. Which putty is better to choose for puttying walls?
Putty is used in construction and finishing works for the final leveling of surfaces and giving them immaculate smoothness The easy-to-use material perfectly eliminates unevenness, cracks, flaws, roughness and is a good protection for all types of ceilings and walls. Depending on what components are included in the mixture, polymer, gypsum and cement putties are distinguished. Each type has its own advantages and is intended for specific work.
Polymer putty is considered a relatively new product on the building materials market. They are divided into acrylic and latex. Both types of putty are ready-to-use material that is sold in containers of various sizes. Acrylic putty is used for roughing, starting, leveling, finishing, internal, external works and finishing of building facades. This putty is easy to apply, functional, and versatile, but has a higher cost than gypsum and cement. Acrylic-based putty is a pure white, thick mass. When working with it, the applied layers are elastic, even, moisture-resistant and highly durable. Thanks to the paste-like texture, you can easily control the thickness of the layers and evenly distribute the material. If you follow the working rules, there will be no shrinkage or cracks after drying. Latex putties can only be used for interior work. They are a mixture of plasticizer, fillers and hardening regulator, in which latex acts as a connecting link. This putty is flexible, easy to work with and apply thin layers. When dry, the applied layers do not crack or crumble. Disadvantages include high cost and response to low temperatures. If stored improperly or frozen, it may lose its properties.
It is impossible to say unequivocally that any particular type of putty is better. Before choosing a material, familiarize yourself with its properties and check the location of the facing work. A good, properly prepared putty has a viscous, plastic structure, a granular base and will be the best of its kind.
Wall finishing is a rather lengthy and multi-stage process. First comes the preparation of the walls. It is not always limited to shaking off dust and priming. In some cases, it is necessary to make a notch, stuff shingles or mesh onto the walls. Of course, even before the work described, it is necessary to remove what does not adhere well to the walls.
The next stage is plastering the walls. Plastering work can be carried out different methods, but since before this we were talking about pre-preparing the walls, then at the second stage wet plaster is performed. Wet plaster is applied cement mortar or gypsum plaster mortar. Since the methods of applying gypsum plaster solutions are similar to the methods of applying putties, the division by name of these mixtures is conditional; some call them putties, others call them gypsum-based plaster mixtures. To be more precise, the mixtures are designed to apply layers of different thicknesses in one pass, but there is no gap in thickness (no obvious edge) and many passes can be made.
When installing dry plaster, the work is completely different. It can be glued to a solution or special glue directly to the surface, and then the wall requires appropriate preparation. However, more often plasterboard sheets are attached to profiles made of aluminum, steel or wood. In this case, preparation of the walls is practically not required.
After the plastering work is completed, it does not matter whether it was dry or wet plaster, the walls are puttied. It is needed to give the walls a perfectly even surface and to seal small cracks and seams. Also, puttying gives a uniform color to the wall, which is important for subsequent final finishing. It is not required only if tiles will be glued to the wall.
On final stage finishing works Wallpaper can be glued to the walls, paint applied or decorative plaster. Wallpaper is very sensitive to the evenness of the wall, it can also show through, and therefore requires a uniform coloring of the base. Painting also requires the same. This is why putty is very important.
Types of putties
The choice of putty mixtures today is very large. First of all, they differ in astringent property. This can be cement, acrylic binder, gypsum binder, or other adhesive.
Putty is often white in color; limestone can be used as a filler, marble chips, chalk or other small fractions from various materials.
Based on the state in which putty mixtures are on sale, they are divided into ready-made ones, which have a consistency similar to sour cream, and powdered ones, which will later have to be diluted with water to prepare them.
Putties also differ in color and purpose. Some of them can be used outdoors or in wet areas, others are of little use for this. There are putty mixtures designed specifically for wooden surfaces, their peculiarity is that they are more elastic and can withstand variable loads longer. In addition, such wood mixtures can have a corresponding color. If we talk about putties for wallpaper and paint, then there are some differences, which will be discussed below.
In general, putties can be divided into those intended for wood and others. Most of these putty mixtures are suitable for wallpaper; only oil-adhesive putty is considered unsuitable.
Starting and finishing putties
Starting putty mixtures are designed to level out significant differences of up to two centimeters. It's more likely plaster mixtures, rather than putty, but they are applied to the walls with the same movements and tools.
Finishing putty mixtures are applied at the final stage; the thickness of the layer they form is on average about a millimeter. Very important quality finishing putty is that it gives the wall a uniform color and shade.
In addition to these types of putties, there are special ones that are designed for sealing seams and cracks. Such mixtures, for example, include “fugenfüller”, which is used when sealing seams between plasterboard sheets, and “satengypsum”, which is used to seal cracks.
Examples and characteristics of putty mixtures.
The choice of putty mixtures is very large, some are designed for one thing, others for another. They also differ in price. Most of them are suitable for wallpaper, but may require some professional skills. Oil-adhesive putty is suitable for finishing wooden surfaces, but is unlikely to be suitable for wallpaper, since stains may appear on them.
Below are examples of putty mixtures based on gypsum or cement. All of them are suitable for wallpaper. The designations of these mixtures may contain the letters LR or KR. This says that the mixture is intended for internal use residential premises. Mixtures containing the VH designation can be used in damp areas. It is also important what color the putty is.
- Concrete is considered a popular material; it is suitable for wallpaper, but not for painting.
- Knauf - used for sealing seams in plasterboard surfaces. Compared to bentonite, the consumption here is approximately one and a half times greater (it is difficult to say how the calculation was made, apparently we are talking about a layer of one millimeter over an area of one square meter).
- Eunice is a good finishing putty mixture.
- Prospector and Hercules are domestic putty mixtures that are considered suitable in damp rooms.
Here is another comparison between “Betonit LR” and “Bolars Finishing Super”:
- the maximum fraction size is 0.3 and 0.2 millimeters, respectively,
- Consumption of the mixture for bentonite is slightly higher,
- the time of use of the prepared mixture is 48 and 24 hours, respectively,
- Drying time is 24 and 2 hours respectively.
One layer: perfect surface putty
In this case, concrete is suitable for leveling the surface, since the applied layer can be from one to five millimeters thick. Bolars turns out clean finishing putty, since the layer thickness should not exceed two millimeters and may be less than one millimeter.
This list of materials will undoubtedly help you determine which putty is best to choose for the wall.

How to choose putty for walls
Which wall putty is best? Acrylic putty solutions are considered to be of the highest quality and best applied, but they are relatively expensive.
More likely, ready-made mixtures, mixed with water, have more high performance compared to the solution that can be prepared manually on site (they fit better on the surface). However, such mixtures are stored less than powder, so when purchasing it is worth opening the bucket and looking for solid fractions in the mixture; it should be homogeneous.
If you choose cement or gypsum putty in powder form, then you must be guided by the size of the fraction. A larger fraction is used where it is necessary to level the surface of a wall, a smaller fraction where it is necessary to give uniformity to the surface or when leveling surfaces finished with plasterboard sheets.
Putting the surface under the wallpaper
Otherwise, everything depends on your skill, what experience you have and the size of your wallet. For gluing wallpaper will do almost any mixture. It’s up to you to decide which putty to choose for the wall.
And a little about the author’s secrets

- pain during or after exercise;
- inflammation in the joints and swelling;
- causeless and sometimes unbearable aching pain in the joints...
Now answer the question: are you satisfied with this? Can such pain be tolerated? How much money have you already wasted on ineffective treatment? That's right - it's time to end this! Do you agree? That is why we decided to publish an exclusive interview with ARMEN DZHIGARKHANYAN, in which he revealed the secrets of getting rid of joint pain, arthritis and arthrosis.
Attention, TODAY only!
Wall putty - important stage repair work. Before we begin to understand the merits of this or that putty or putty for wall finishing, let’s clarify whether these are different materials. The Russian dictionary does not distinguish between these words, just one of them, “putty,” came to us from German language and is based on the word “spatel” - a spatula or plate with a handle, used by doctors and painters.
In construction, such a shovel is used to level the surfaces of walls, ceilings and floors, if necessary. The word “putty” (hence “putty”) has a purely Russian root “tow”. Tow was used to seal cracks in houses, using a thin stick or flexible spatula, wide at one end and with a comfortable handle at the other.
Since the German Spatel was best suited for this work, it “took root” in Russian workshops, and the mixture used to seal and level the walls was called “putty” or “putty” - it makes no difference.
Initially, the putty was mixed with your own hands according to your own recipe, the composition practically did not change: lime-sand mortar, mixed to a thick sour cream. Later, oxol (drying oil), animal glue and chalk were added to the materials for puttying walls to give the mixture aesthetic whiteness and additional low shrinkage when hardening.
Modern putty mixtures have also undergone some changes in their composition compared to the last century. Which? This is what we will look at now, and at the same time we will find out why putty is needed and whether it is really necessary.
On video: smooth plaster or smooth putty.
Putty (putty) – universal, quickly hardening finishing composition special materials used for leveling and repairing walls and other surfaces before subsequent finishing work.
Judging by the popular name “putty”, this mixture is designed to cover cracks, potholes, joint seams and other surface irregularities.
Types of building mixtures
The mixture can be dry (sold in bags) or diluted to the desired consistency - a ready-to-use paste. Both of them have a number of advantages and a number of disadvantages over each other. How to understand all the intricacies yourself if you have never putty before?
The binding component is the basis of all putty putties. The division of all mixtures into:
- cement putties;
- gypsum putties;
- polymer (acrylic).
Cement
It is clear that the binding component in these mixtures is cement, which imparts its best qualities to the putty: moisture resistance, durability, and resistance to the external environment. This material is indispensable when finishing rooms with high humidity and sudden temperature changes (kitchens, bathrooms, etc.)
This is an excellent material for walls outside buildings, but then lime (cement-lime putty) is added to its composition. The main disadvantage is the high degree of shrinkage.
Plaster
The second name is gypsum plaster. The advantages include:
- quick “setting” of the composition;
- plasticity and ease of use when plastering walls and ceilings;
- formation of a smooth, durable surface after drying;
- does not shrink.
The main plus is gypsum putty walls will be fully invested in the democratic estimate. The disadvantage is that the material is not resistant to water, which means it cannot be used in wet areas.
Polymer (acrylic)
The most modern and convenient option for putty mixtures. In terms of adhesion, non-shrinkage, uniformity of drying, and complete absence of shrinkage, it has no equal. Thanks to its fine-grained structure, which gives a very smooth and high-quality hard surface, it can be used acrylic putty not only when repairing walls, but also for connecting parts of different compositions.
The mixture is capable of holding glass and stone, plastic and fabric, brick and drywall, and any surface to be puttied. Ideal for finishing. This - universal option wall plastering work! The downside is that the price is steep.
However, the quality of the putty must correspond to the quality of the materials used in construction. Only with this combination can full interaction of materials and high quality work be achieved.
Technical characteristics, methods of use and the expiration date must be indicated by the manufacturer on the packaging.
Dry and ready-made mixtures
The manufacturer will also offer 2 types of putty mixtures - dry and in paste form. Dry mixtures are characterized by a low price and long term storage They contain everything necessary components are in a dry state, and for cooking technical solution All you need is water and thorough mixing. The simplicity of these actions and the affordable prices of such putties make them leaders in the construction market.
However, there is also negative points: short period of use of the batch - you will have to mix in small parts and work with a spatula very quickly. The mixture dries out literally before our eyes, so you should hurry.
Wet (ready-made) putties do not have such a hardening speed. In addition, they do not require compliance with instructions for proper mixing, but their shelf life is significantly lower than dry, not yet diluted mixtures. The paste also shrinks a lot, and their prices are high. It is more convenient to work with them, on the one hand, but on the other hand, applying them in a layer less than 2 mm is not recommended.
If there is a large-scale repair with putty large areas, it’s better to stick with pastas.
If you are going to plaster and putty the wall with your own hands, you will need these tools:
- wide and narrow spatula;
- building code;
- bucket and construction mixer (if dry mixture is available);
- grater for polishing the surface after puttying.
Putty stages
The procedure for plastering walls is as follows:
1.Starter or putty in the first layer. For this type of work, a coarse mixture is suitable, which is called starting putty. Suitable for covering large differences, you can hide holes and grooves, putty walls partially or completely, depending on the evenness of the walls. The thickness of the starting layer can reach up to 1.5-2 cm, and to give the surface strength, after covering deep cracks and holes, you need to use a painting mesh.
The strength of the first layer is ensured not only high-quality alignment, but also complete adhesion with subsequent building materials. Why putty the walls before painting or wallpapering? - To keep it better!
And don’t forget that before applying the next layer, you need to let the previous one dry thoroughly!
2.Putty for the second layer or lighthouse. The mixture is no different from the mixture for the starting layer. Beacon - a straight, even strip of wood or metal profile. Using this rail we will align the walls horizontally and vertically. You need to fix the beacons on the wall and start the second layer of putty.
Using a level, we carefully check the quality of our secondary finishing.
By the way, if the walls turned out smooth after the starting, first layer, you can skip this stage. The decision is made depending on the chosen decorative covering walls
3.Finishing or putty in the third layer. Whether or not you decide on the second layer, you will have to do the finishing putty. Why do you need putty if the walls are already perfectly smooth? It is this that will give the surface ideal smoothness and eliminate the smallest cracks that could form during the drying of a thick layer. Last finishing layer should be thin, almost transparent, like a primer, which you, of course, did not forget to apply under the first, starting layer.
Since finishing putty is akin to a primer, it is not difficult to make such a primer-putty for walls with your own hands: just dilute the remaining mixture liquid-liquidly. Often this method of priming ( liquid putty) is used before applying the first starting layer, but this is wrong! A real primer will adhere better, penetrate deeper, and prevent the appearance of mold. Use the right primers, there is one for each type of putty!
Universal putties are very convenient in all respects and for all layers; working with them is a sheer pleasure, and the most unprepared novice master, who does not know how to hold a spatula correctly, can handle it.
Important Rules
When working to level walls, you must adhere to the following rules:
- Puttying is carried out on strong, solid bases.
- The base must be absolutely clean.
- The putty is applied after priming the surface to create an adhesive effect.
- Apply layers using a wide spatula.
- For large uneven areas, apply another 2-3 layers.
- Each layer should be given time to dry thoroughly.
- You will have to putty the walls for wallpaper three times, and up to 5 times for painting.
- The finishing putty is applied with a thin primer layer.
- After completely dry For the last layer, be sure to sand the wall with fine-grained sandpaper.
“In everything big there is gradualness, not suddenness and instantaneity!” - I noticed once great poet and the philosopher Goethe. This principle must also be adhered to when plastering walls; this is a prerequisite: apply a layer - wait until it dries completely! Otherwise you won't get a masterpiece. The wallpaper will bubble and become covered dark spots, move away from the wall and hang from the ceiling. The paint will lie in uneven stripes, swell and crack in the very first weeks after painting.
Puttying walls with your own hands is not a difficult task, as it might seem at first glance. The small but very useful video tutorials from professional craftsmen below will help you use the tools correctly and apply layers.
How to putty walls (2 videos)
Putty is a special composition that is used for leveling, as well as decorative finishing of walls and ceilings indoors. They happen different types and differ depending on their composition, purpose and degree of readiness for use.
Types of putties and their main characteristics
Based on their composition, putties are divided into gypsum, cement and polymer (acrylic). Gypsum putties are relatively inexpensive, easy to level and practically do not shrink. Their only drawback is poor resistance to moisture, which limits their scope of use. Cement-based putties have excellent moisture resistance, but have a high degree of shrinkage. Polymer putties are waterproof, do not shrink and at the same time provide a very high quality of the finished surface. Their only drawback is their too high price.
According to their purpose, putties are divided into leveling (starting), decorative (finishing) and universal. Starting mixtures are characterized by high strength, good adhesion and large grain size. They are used to level walls after plastering and can be applied in variable thicknesses from 3 to 20 mm.
Finishing putties are intended for application to the surface immediately before decorative finishing. They provide the most even and smooth surface possible, hiding small imperfections in the wall. This putty is applied in a layer of 0 to 4 mm and is easy to process, but has less strength than the starting one.
Universal putties combine the properties of leveling and decorative mixtures. They can be used in cases where the wall does not have too many flaws. Universal putty is more expensive, but its properties are somewhat inferior to specialized starting and finishing coatings.
According to the degree of readiness, putties are ready and dry. Dry putties are cheap and have a very long shelf life. The main disadvantages include the short shelf life of the already prepared mixture, dust and dirt during operation, as well as the need for careful adherence to proportions when preparing the composition.
When using ready-made putties, there is no need to waste time preparing the mixture, and there is practically no dust during the work. However, such materials are much more expensive, in addition, they shrink more, so they cannot be used for applying layers with a thickness of less than 2 mm. The shelf life of ready-made putties is significantly shorter than that of dry building mixtures.
Let's look at the main features and performance characteristics putties from various manufacturers.

When choosing a putty, first of all you need to determine the operating conditions of the coating. For residential premises with normal humidity, gypsum-based putty Knauf or Ceresit is suitable. For the kitchen or bathroom, you can use cement-based putty SCANMIX or universal Kreisel. The latter is also suitable for outdoor use. SCANMIX polymer putty can be used for interior decoration of any premises, but if you decide to purchase it, take into account the area to be covered, and also calculate the amount of material required in advance.
Putty is used to level the surface before applying the final decorative coating. Putty solutions may vary in form of preparation, characteristics and purpose. Before purchasing, you need to carefully study all the varieties in order to decide which mixture is best to use for a particular case. This article will discuss the characteristics of various putty compositions, and also identify which putty to choose for walls under wallpaper.
Types of putties by composition
The composition of the putty finish can vary quite a bit. There are these types:
- oil-glue;
- gypsum cement;
- water-dispersed;
- acrylic.
Oil-adhesive putty
This variety is one of the cheapest and is made on the basis of drying oil. They are not used so often, since drying oil is harmful to wall cladding; it is absorbed into the surface and then appears as spots on the applied coating.
But some people use this solution, as it improves waterproofing and protects the base plaster from cracking. So for basements, an oil-glue mixture can be used, given that the walls of such rooms are practically not lined.
For wooden plastered surfaces, oil-adhesive putty is even useful: it will protect the coating from rotting and also prevent rust from appearing on the nails. Only a putty mixture of this type can provide maximum service life wooden walls.
Gypsum cement mixture
Gypsum cement putties have a higher cost, but are suitable for cladding almost any surface. They are produced in the form of dry mixtures; to use they will need to be diluted in water.
Solutions for residential premises are marked with LR or KR, and for rooms with high humidity - VH. The main purpose of these solutions is to putty walls under wallpaper.
Water-dispersion mixture
Such solutions also belong to the category of gypsum cement, with the only difference that they are already mixed with a water emulsion and are sold in buckets. Their cost is slightly higher than their dry counterparts, but there is no need to prepare for work; the mixture can be immediately smeared on the wall.
The main thing is to always close the bucket, otherwise the wall cladding may become fragile.
The water-dispersion composition is distinguished by its maintained viscosity, as it is produced using an industrial method, high strength and smoothness. The mixture is easy to apply, and when sanding it adheres firmly to the surface. When choosing from all putties, a water-dispersion solution is best suited for beginners; getting a high-quality wall for wallpapering using this mixture is quite simple.
Acrylic
Acrylic compositions have all the advantages of the previously discussed putties, but they also have a very significant drawback: cheap paint adheres extremely poorly to a surface treated with such a mixture. This is due to the fact that after covering the wall with acrylic putty, it becomes too smooth. Therefore, you will need to spend extra money on purchasing more expensive paint.
Types of putties by function
Based on functionality, putty compositions can be divided into the following:
- Starters. Used to seal defects and eliminate small unevenness on walls. This mixture does not shrink and cracks and peeling do not form after it. When leveling surfaces, it is used as the first layer. Without obvious defects, such putty should not be used.
- Finishers. Allows you to hide defects in order to level the wall. It is the second facing layer. Such a putty mixture should have perfect whiteness.
- Universal. Combines the characteristics of the previously discussed varieties. It is also used for walls without obvious defects. The cost of such a mixture is slightly higher, but the quality is extremely high.
Puttying walls under wallpaper
Many beginners are wondering which putty is best for walls under wallpaper. The solution can be applied to different surfaces: concrete, brick or covered with plasterboard. It is imperative to apply the mixture to drywall, especially if you plan to glue paper light wallpaper, without putty, the seams of the drywall sheets will be visible underneath them. Also, if you neglect to apply construction mixture, removing the wallpaper will be extremely difficult.
Most people don’t know how to choose putty for walls. The choice of putty for walls should be made taking into account the following recommendations from specialists:
- For beginners, it is better to purchase a ready-made solution; there is no need to worry about the composition of the finish.
- It is highly not recommended to use putty for external procedures. It may be harmful to human health if used inside a building.
- You won’t need a lot of putty mixture, so it’s better not to save money and purchase a solution from a well-known manufacturer, this will ensure a higher quality of cladding.
- Optimal results can only be achieved by using mixtures from one manufacturer that are compatible with each other, and their characteristics are combined and complemented.
- When purchasing, you should always follow the manufacturer’s recommendations, which, taking into account the parameters of the leveling solution, indicates: the purpose of the mixture, the conditions of its use, operating conditions, consumption and the possibility of combination with other facing compounds.
- To prepare the surface for painting, it is better to putty the wall with ready-made solutions; they have a higher quality finishing layer. But to putty walls under wallpaper, it is better to use dry mixtures.
- When purchasing ready-made finishing putty, slightly open the lid with the mixture, this will allow you to evaluate its quality. If hard inclusions are visible on the surface, the quality is unsatisfactory.
- For internal lining surfaces optimal choice mixtures will become sand-free.
- European manufacturers guarantee high quality finishing. Despite their high cost, experts recommend purchasing putty from foreign brands.
Drywall joints need to be puttied in mandatory, especially if wallpaper will be used as a finishing coating.
Before applying the putty, the drywall will need to be treated with a primer. After which a layer of putty is applied, often used for such purposes finishing mixture. If used ready putty for walls in dry form, before mixing it, you must carefully study the instructions indicated on the packaging of the material. It will not be possible to mix the solution well by hand, so you will need to use construction mixer or a drill with a special attachment. You can learn more about applying putty under wallpaper from the following video.
Requirements for putty under wallpaper
The characteristics of the putty are great value. The result of the cladding largely depends on the quality of the solution. The mixture must meet certain requirements:
- High level of adhesion and service life.
- Can be applied over base putty.
- The solution should not contain lumps, but should easily follow the spatula.
- The mixture after cladding should not flow down the walls.
- Even a thin layer of high-quality cladding removes surface defects.
- After the composition has hardened, all defects, in the form of cracks or splits, must be repaired.
