What is the putty used for?
Putty is most often the basis for painting walls inside country houses. This term is derived from the word "spatula", which is used to level the composition. There are 3 categories of putties. The first two are designed to create the 1st, 2nd layer, the third is universal.
The leveling putty is used to treat overlaps, gaps, large cracks. The finishing material can be used for small irregularities.
To get the perfect result, it is better to buy building materials for a specific surface.
The putties can be based on:
- Gypsum. It can be used to handle large cracks in concrete, brick walls, gypsum boards. You cannot use it in the kitchen and bathroom;
- Cement. Waterproof material that shrinks, therefore multiple coats are required;
- Polymers. A universal option is a polymer putty, it is superelastic and can be supplemented with various coloring pigments. You can make thin layers, this makes it possible to significantly save the consumption of the mixture. To increase the binding effect, you can use paints and varnishes, drying oil, polymers;
- Gypsomel structure. Designed for dry rooms. It can be used for leveling joints of drywall and concrete surfaces;
- Butter. Oil putties are used for treating wooden surfaces, for example, windows, or in houses made of timber. This type of building material protects them from the weather;
- Glue. The glue putty can be used to finish the surface on top of the plaster layer.
The putties can also be ready-made and dry. The dry mixture must be diluted with water. The ready-made filler can be used to treat smooth wall surfaces, which must then be sanded.

PVA based putty
Our aunts brought us chalk and CMC. Vadik and I bought PVA glue ourselves. Instead of talcum powder, we were provided with baby powder. Then we explained that the quality of the putty is influenced not only by the proportional amount of components, but also by the quality of grinding of chalk, purity of talc and others. Therefore, we forced our aunts to calculate the ratio of these components for us to obtain a mixture with the given characteristics:
We putty the walls with our own hands
In ready-made putties, in addition to basic substances, various plasticizers, antiseptics and a number of other components are introduced. All additives improve the quality of the material. The cost in the store is slightly higher than homemade putty.
For those who want to make a composition on their own, I will tell you some points. Mix the dry ingredients first, then pour in the liquid. Dissolve the CMC with water until it becomes sour cream. It, like talc, should not be more than 10% of the total weight, excluding water. As a result, you should get a mass similar in consistency to homemade sour cream.

DIY structural paste.
It often happens that a structural paste is required for the design of the work, but it is not at hand. For some types of work, the putty is not suitable, it is thicker, grainy and less elastic. In many cases, it is more convenient to work with textured or structured paste: for example, drawing patterns from a syringe or sachet, creating soft textures. In addition, the putty is much worse tinted and often gives white blotches on the finished relief.
We hasten to please you - it is not necessary to buy different types of structured pastes for a lot of money. You can make them yourself!
We have selected and tested three of the most common homemade structured paste recipes for you.
1. Putty (universal acrylic for interior use) + PVA glue. The ratio is about 1 tablespoon of putty to 1 teaspoon of PVA. The proportion can be changed in one direction or another, depending on how thick or liquid paste you need. The mixture turns out to be very elastic and viscous, it is well applied with a syringe or a narrow nozzle of a tube. In a closed container it is stored for about two weeks, then it gradually dries up. It is better not to dilute with water, lumps appear that can ruin the work. Therefore, it is better to prepare a small amount of pasta every time before decorating and not leave it in reserve.
2. If you need a thicker paste with preservation of the above properties (for example, to create snow or more "lush" volumes), you can add starch "by eye" to the first recipe. All the pros and cons of such a paste are preserved for this recipe.
3. If there is no putty on hand, it doesn't matter, you can try this recipe: mix 1/2 cup of baking soda or talcum powder with 2 tablespoons of PVA and add 1-2 tablespoons of white acrylic paint. The result is a rather thick viscous mixture that perfectly holds volume and is perfect for working with stencils and creating textures.
To create a variety of structured pastes, you can add fillers to the above recipes: semolina, fine sand, glass balls, poppy seeds, coconut, and whatever else your fantasy tells you. In addition, all these pastes are perfectly tinted with acrylic paints.
Features and characteristics
Repair and interior decoration of any room involves the purchase of various finishing building materials. Among the huge assortment, it is sometimes very difficult to choose a high-quality and inexpensive putty. In this case, advice from experienced repair and interior decoration masters will help. According to experienced specialists, the putty produced by the company "Starateli" is the best option.
Basic
The base mix is very popular and in high demand among buyers. This material is used for finishing both the inner surfaces of the walls and the outer ones.
The base putty is resistant to high humidity, it is applied to the surface in a thin layer, no more than eight millimeters thick. The presence of a substance such as cement in the mixture significantly expands the scope of use of this material. In some cases, covering the surface with a base putty is used as a base for painting walls.
Finish
Also, the finishing mixture "Prospectors" was widely used for finishing works of various premises. Finishing putty "Prospectors" is deservedly considered one of the best mixtures of this kind. The developers tried to choose the smallest particles for it, creating a perfectly flat surface. This material contains gypsum. This component gives the solution certain properties.
There are several varieties of this brand, but each of them has excellent, unsurpassed adhesion. So, the finishing compound is able to cover any deformations of the base layer and easily fits on a variety of building materials. Builders can prepare the mortar of the desired consistency by varying it flexibly.
The finishing solution is applied in an even layer, no more than five millimeters thick. You should not prepare a large amount of solution at once, as the finished mixture tends to dry quickly.
Finishing putty KR, created on the basis of PVA, is a high-tech mixture with excellent characteristics, suitable for interior decoration of premises with low humidity levels.Crystal white putty is made on a polymer basis. The manufacturer provides packaging of 20 kg. The applied layer of this material has excellent adhesion properties and dries quickly. When finishing the wall surfaces with the KR finishing solution, the room must have a positive temperature.
The Finishnaya Plus mixture is made on a polymer basis, which includes cement. This putty is used for interior decoration of premises as a leveling layer on the surface of concrete, plastered and plasterboard walls. This material is resistant to high humidity, so this putty can be used for finishing any premises. Such a cement mixture in bags has mostly positive reviews.
Peculiarities
The finished putty differs from the usual compounds that have to be mixed directly on the construction site or in the house being renovated. It is prepared entirely at the facility where the original components themselves are produced. Technologists definitely have more knowledge than ordinary builders, and workers have more special equipment and tools at their disposal, including for quality control.
The finished putty is mixed until a homogeneous cream is obtained, it is very easy to apply it to any surface, making this surface very smooth and even throughout. All on-site cooking is limited to stirring in a bucket, only occasionally more water needs to be added.
An important advantage of the ready-made mixture is not only saving efforts, but also reducing the time that needs to be spent to perform the necessary work, improving the result achieved.
Features of choice
Apply putty to primed walls
You should never dismiss the advice and recommendations regarding the choice of putty, which professionals and specialists are ready to give. It is necessary to carefully study the instructions and prepare the composition strictly in accordance with the attached manual.
The choice should be based on the characteristics of the surface on which the composition will be applied, the degree of its damage, location, conditions of the forthcoming operation, the level of humidity in the room, compatibility with other materials used during the work.
Dry mixes are more suitable for creating a base for wallpapering. The choice of a universal compound for wall putty will help create a complete coating on any surface and in the most difficult conditions.
One of the main advantages of universal formulations is high adhesion and elasticity.
These qualities allow them to work on any surfaces. For more information on wall compositions, see this video:
No. 2. Types of putties by appointment
According to the purpose, the putty is usually divided into the following types:
- starting (leveling);
- finishing (decorative);
- universal.
The main difference is the grain size of the material.
Starter fillers have high grit size, excellent strength and adhesion. They are intended for leveling walls with visible defects and a difference of up to 10-15 mm, they can be applied with a layer of 3 mm to 2 cm. Such compositions can be used as an independent leveling agent or used after plastering. For best results it is better to apply the starter putty in a couple of coats. You can work with two spatulas: one a little more - for applying the mixture to the wall, the second - for taking the mixture from the container. If the wall surface contains not just defects in the form of pits, but has vertical deviations, then you will have to take a long building rule.
The finishing putty is applied over the starting putty, intended for the final wall cladding before decorative finishing (painting, wallpapering). Such compositions are characterized by less granularity, therefore, they allow you to form a perfectly flat and smooth surface.In terms of strength, the finishing putty is inferior to the starting one, it can be applied with a layer of maximum 5 mm, it is easy to process. As in the case of the starting compound, it is better to apply the finishing compound in two coats. For the subsequent painting choose a fine-grained putty (100 microns).
Universal compounds are suitable for both leveling and finishing. It makes sense to use them when the surface is characterized by minimal irregularities and differences. Such putties are more expensive than starting and decorative ones, but inferior in quality to them. In the presence of serious flaws, it is more advisable to take two separate compositions - you will win in money and in result.
The best finishing putties
The purpose of this finishing material is to create a topcoat that should serve as the basis for painting or wallpapering. For the analysis, 6 mixtures and liquid compositions were taken, of which only 3 combine high quality, safety, affordability and ease of use.
Danogips Sheetrock SuperFinish
Danogips Sheetrock SuperFinish is sold as a ready-to-use paste. On the market you can find two volumes - 5, 5.6 and 28 kg in buckets. The mass has an optimal consistency in terms of density, does not spread over the surface and does not dry out instantly. This makes it possible to correct the applied layer, which, according to the instructions, should be thin - about 2 mm. The scope of this material is quite extensive - processing of concrete, drywall, lime plaster. It is used both for the complete decoration of walls and ceilings, and only for closing seams or small cracks.
Danogips SuperFinish putty mixture is suitable for use in both industrial and residential construction. It can be applied either manually with a spatula or mechanically. This material is intended only for work indoors, the temperature at this time should be within + 13ºC. The composition has a uniform texture and a smooth white finish.
Dignity
- Does not require mixing of components;
- Good astringent properties;
- Snug fit to the base;
- For a long time, it does not crack and chip;
- Easy to sand.
disadvantages
- It splashes a little during surface treatment;
- A special application tool is required - a gun, brush, etc.
TEX Finishing Profi
Introducing a ready-to-use latex finishing putty. According to reviews, it is not difficult to apply due to its soft texture and optimal consistency. It is actively used both for complex wall decoration and for partial processing of seams, joints, cracks. The composition fits perfectly on a concrete, plasterboard, plastered base, and on top you can safely glue wallpaper or apply paint.
TEX Profi copes well with both ceilings and walls, but it can only be useful for interior work. For their successful implementation, the air temperature in the room should not be lower than + 5ºC, and the humidity should not be less than 80%. This composition is not obstinate in application, but thorough cleaning of the base from contamination is still inevitable.
After this, it is important to allow the coating to dry, which will take up to 4 hours. If desired, a primer from the same manufacturer can be applied over the putty layer.
Dignity
- Ease of application;
- Levels the surface well;
- The finished coating does not crack;
- A wide selection of packaging - 1.5, 5, 8, 16 and 30 kg;
- Fast drying of the coating - about 4 hours.
disadvantages
The maximum permissible layer thickness is 3 mm.
Putty "TEKS Profi" is applied using an ordinary spatula, and it is better if it is wide and long enough to avoid spreading of the composition.
Hercules GT-33
Finishing putty "Hercules GT-33" is designed for leveling joints in gypsum fiber board and gypsum board, as well as ceilings and walls.It is sold in dry form, and the powder must be diluted with water in proportions of 0.55-0.7 liters of liquid per 1 kg of raw materials. It is not recommended to cook a lot of the composition at once due to the rapid loss of elasticity. Due to fine grinding (the largest particle size is 0.3 mm) and good solubility, no lumps remain in the mixture and it does not need to be intensively mixed.
This composition has high plasticity, which facilitates surface treatment. It is primarily intended for concrete work, but the finished coating can be painted or wallpapered. Due to the combination of polymers, gypsum and finely dispersed mineral fillers, its high-quality adhesion to the base is ensured. Its minimum permissible thickness is 0.3 mm, while there is no maximum border.
Dignity
- Beautiful white color;
- Uniform texture;
- Shelf life - 2 years;
- Adequate consumption of the working mixture - 1.0 kg / m2;
- Tightness of the package;
- Good density.
disadvantages
- Must be applied strictly at a temperature not lower than + 5 ° C;
- Not suitable for outdoor use.
Dry putty mixture "Hercules GT-33" is available for sale in two volumes - 5 and 15 kg, when choosing a larger amount, you can save a little.
Self-made material
If desired, the putty mixture can be made independently. All components for it are sold in hardware and hardware stores. You will need:
- PVA (glue) - 1 part;
- chalk (talcum powder, baby powder, sawdust dust, dry gypsum plaster - optional) - 2.5 parts;
- plasticizer (dry wallpaper glue or glycerin, drying oil) - 0.05 parts.
As a plasticizer, some introduce casein glue, liquid or grated laundry soap, but with drying oil, the smoothness of the composition is the highest. It is impossible to ignore the addition of this component, otherwise the work with the putty will be laborious. First, the dry components are mixed with each other, then they are diluted with PVA, after which other liquid ingredients are introduced into the mass.
It is necessary to ensure that the homemade putty resembles thick sour cream, since a product that is too liquid will lie unevenly, with influxes. Sawdust is added if the mass is planned to be used to seal cracks, and for finishing the walls it is better to add white components to the composition.
No. 3. Types of putties according to the degree of readiness
There are few options here - putty can be sold in two versions:
- dry mixture requiring dilution with water in strictly defined proportions;
- ready putty.
Dry mixes are the most widely sold, as they are inexpensive and have a longer shelf life. Such putties are sold in packages weighing from 5 to 25 kg, they are easy to transport and store. In order to obtain the necessary pasty putty from a dry powder, it is enough to seal the composition with water in a certain amount. It takes a little time for mixing and stirring, but the putty obtained in this way quickly sets, therefore it is necessary to work quickly, and kneading the material in large batches will not work. To obtain a solution with clearly defined parameters specified by the manufacturer, it is necessary to act strictly according to the instructions. Some also consider the need to spend time preparing the solution as a disadvantage, but, to be honest, this is not a very big time investment. Another disadvantage is the presence of dust during mixing.
Ready-made formulations are sold in buckets or large tanks. It is easy to guess that they can be used immediately, and this saves time and there is no risk of violating the proportions, having received a putty of the wrong quality. Additional tools and containers are also not required. The shelf life of the finished composition is less than that of dry putty, but much longer than that of dry putty diluted from powder. Ready-made compositions are more expensive than dry ones.

Release form
The following division into types depends on the form of release:
Dry
You can control the consistency level, but it is very important to properly dilute the solution itself and then apply it to the surface without errors. Adheres very well to the substrate.
Pasty
Available in plastic containers. The cost, of course, is higher from a similar, but dry mixture. Also, the builder is deprived of the opportunity to independently regulate the consistency of the mixture.
The color of the cement in the composition determines its category:
- gray mixture;
- white cement putty;
- super white composition.
Gray
Dry finishing gray putty contains cement, some mineral fillers and all sorts of functional additives. The mixture is quite moisture resistant and plastic, very easy to apply and spreads without much effort over the surface, has very good adhesion to the base of application.
It is used for rough leveling of the surface layer of ceilings and walls lined with concrete or brick. The gray putty has worked well for indoor (outdoor) work on surfaces that are regularly exposed to moisture or temperature changes.
Cement white
White cement putty has good adhesion (the ability to firmly adhere to the material of the applied surface) to any mineral substrates and is weather-resistant. White putty is used to smooth out roughness, fill irregularities and cracks on concrete, cement and even lime-cement surfaces. Very easy to sand and paint. The maximum applied layer thickness can be up to 30 mm.
Super white composition
The composition includes white cement, necessarily quartz sand, polymers and some pigments (ground marble), due to which the finished surface acquires a perfectly white, snowy color. When dissolved with water, a very plastic mixture is obtained, which, after hardening, forms a rather strong frost-resistant and moisture-resistant layer. Can be applied to cement, concrete, reinforced concrete and cement-lime surfaces. Professionals recommend using such material only if the room will be finished with bulla paint. Why? The answer is obvious. This type of putty has a high price and this is its main drawback.
How to prepare finishing mortar?
Correctly preparing the finishing solution is a very important point, since it depends on how high-quality the coating will be and how easy it is to work with the finished solution. The most important point in this process is the careful observance of all the necessary proportions and the uniformity of mixing the solution.
You should follow the advice of experts when mixing the solution.
- To prepare the mixture, it is better to use a plastic container in the shape of a cylinder. The smooth walls of the container are much easier to clean after finishing work.
- The required amount of water is poured into the prepared container, then, stirring constantly, the mixture is gradually poured, which will avoid lumps.
- A small amount of the solution can be mixed by hand. If a significant amount of ready-mixed mixture is required for finishing the room, it is more advisable to use a mixer. The putty consumption must be calculated in advance, before starting work.
- It is necessary to take into account the fact that the solution must be kneaded twice. A dry mixture is poured into a container with water, thoroughly mixed. Next, you need to let the solution stand for a while and stir again thoroughly.
Each package of dry material contains detailed instructions, in which you can find the exact proportions of water and putty to create a high-quality solution, and an accurate description of each stage of mixing the mixture. Therefore, before mixing the solution, you need to carefully read the instructions. Only if all parameters and conditions are observed, a solution of the required consistency will be obtained.
Dry building mixes "Prospectors" are practical and fairly easy to use. The use of these materials greatly simplifies the process of interior decoration.
In the video below you will see the difference in the application of plaster and finishing putty from the Prospector.
Type of work carried out
The entire range of cement-based putty can also be divided according to the type of work carried out:
- decorative;
- heat insulating.
Decorative
The basis of this type of plasters is gray cement with the addition of colored ground clinker. When applying this type of putty, the texture and color of the main coating in most cases is set by the finishing layer, which is explained by the rather high price of colored cement, in contrast to the classic gray color.
To give color effects and decorative texture, colored sand, lime or crushed rock particles are added to the mixture.
Heat insulating
It is used for leveling and thermal insulation of building surfaces made of bricks, concrete, aerated block masonry, ordinary cement or gypsum plasters. The composition contains special additives and a light filler (foam balls), which, having poor thermal conductivity, perfectly retains heat in the interior. The term of use is approximately 3.5 years.
Application method
It should be said right away that PVA putty is intended for finishing and is applied over the plaster or base putty. The fact is that, due to technical features, it will be rather difficult to create a thick leveling layer from it. For more information on the properties of this mixture, see this video:
Preparation of the base
The better the base is prepared, the less putty will be consumed
Before starting work, the supporting base must be carefully prepared. First of all, its surface must be leveled using cement or gypsum plaster.
If necessary, it is also possible to apply a base cement putty, intended for sealing small defects of the plastered surface.
It should be borne in mind that the higher the quality of the base finish, the smaller the layer of finishing plaster will have to be applied, and this is a significant saving of time, effort and material.
The next step is to clean and prime the leveled surface. The base is thoroughly cleaned from dirt and dust. To do this, use a vacuum cleaner and a damp sponge.
If it is necessary to remove greasy and oily dirt, the wall should be treated with organic solvents (white spirit, acetone, gasoline, etc.).
After that, we proceed to the application of the primer, which is intended to increase the adhesion between the treated base and the putty mortar.
The primer-composition is applied to the base to be treated with a paint roller or brush. At the same time, in order to achieve a greater effect, it is recommended to make a primer in two or three layers. In this case, each subsequent layer should be applied after the previous one has completely dried.
Putty application
To apply PVA putty to the base to be treated, you will need the following tools:
- Wide and narrow trowel for spreading mortar over large areas.
- Assembly gun - for sealing deep cracks and cracks with a sealant.
- Plastic wrap and masking tape.
- Construction mixer.
Before starting work, cover the floors, windows and doors with plastic wrap and secure it with masking tape. The fact is that PVA tends to be deeply absorbed into the surface, and it can be difficult to remove unwanted stains from putty drops. For the same reason, we glue the door frames, etc. with masking tape. For an overview of glue-based putty, see this video:
Deep cracks on the surface to be treated should be widened and cleaned out with a sharp spatula. Then they are sealed with a sealant or glue solution "liquid nails". This will prevent an increase in cracks, which would otherwise lead to cracking of the putty surface.
Store mixes are stratified, so you need to mix them thoroughly.
Before applying the putty, the finished composition should be thoroughly mixed with a construction mixer. Being in a store warehouse, the finished mixture will inevitably stratify: heavier components will sink to the bottom, and a watery solution will rise up. Stir well to restore the homogeneity of the mixture.
After that, the solution is completely ready for use. We apply it to the surface to be treated using a wide metal spatula.
Using a narrow spatula, spread the mixture over a wide
To do this, the solution is taken from the container with a narrow spatula and evenly distributed over the entire length of the wide instrument. The solution is applied to the plane with wide, sweeping movements
After that, you should wait until the putty surface is completely dry and only then proceed to its further processing. First of all, it will be necessary to prime the layer of PVA-putty again, and after that proceed to painting it or pasting wallpaper. See the main points of proper filling in this useful video:
