Putty: types of mixtures by purpose, their characteristics
The putty hides flaws on the walls and ceilings well, masks the seams in those areas where the cracks were repaired with plaster. The material is presented on the market in a huge range. Each variety is designed for a specific type of work.
There are several types of putties for interior work:
Starting mixtures are used at the initial stage of repair work. They allow you to align the relief of ceilings and walls. The material completely masks traces of self-tapping screws, eliminates damage - chips and cracks. The leveling fillers contain large particles. Thanks to this, the coating is strong and durable. Starter mixes can be applied in thick layers.
The leveling putty dries quickly and is almost impossible to sand. The surface treated with such a mixture becomes rough. Most often, starters are used to level brick and concrete walls. They even allow you to abandon the application of a layer of finishing putty. However, in this case, the surface will be unsuitable for painting or wallpapering. Alternatively, wall panels can be used.
Note! Starter fillers are not suitable for eliminating deformations larger than 5-7 mm.
Universal compounds can be used both for leveling and for creating a finishing layer. This type of mixture is suitable for all surfaces. It should be noted that the cost of a universal compound is higher than the price of a finishing putty.
The use of universal formulations has its advantages:
- the coating turns out to be even and smooth;
- damages on the walls are well masked;
- the treated surface is completely ready for any type of finish;
- the coating has a large margin of safety.
Such a coating is easy to sand. However, despite all the advantages, the combination of starting and finishing mixtures still gives a better result than the universal putty.
In addition, the specialized mixture "Seam" is considered separately. Craftsmen use it for finishing plasterboard to hide the joints between the sheets. This type of mixture is only suitable for minor repairs.
How to choose the best finishing putty: types of compositions, their advantages and disadvantages
Finishing compounds are applied in a thin layer. This material prepares the surface for further finishing. Treated walls can be safely painted, plastering or wallpapering. Finishing mixtures are composed of fine-grained particles. Due to their plasticity, such putties are able to create an absolutely smooth surface. They have a creamy consistency and can only be used on flat walls. The maximum permissible layer thickness is 5 mm.
The material is sold as ready-to-use formulations or dry powders, which must be diluted with water before use. Each of them has its own advantages and disadvantages. On a basic basis, the compositions are gypsum and cement. According to the type of binder component, dispersion, polymer putties and oil-glue are distinguished.
In addition, chakril is found on sale. This finishing white putty has a highly specialized focus. It is used for leveling plastered surfaces and skirting boards. The composition is suitable for preparing ceilings for whitewashing and walls for tiling.
Note! When choosing a putty, it is imperative to take into account the material of the surface that will be leveled, as well as the operating conditions of the room (temperature and humidity level).
A certain type of putty is suitable for each type of work:
- walls - for offices, bedrooms, living rooms, hallways and children's rooms, it is preferable to use a plaster-based mixture. In the kitchen and bathroom, where the level of humidity is increased, it is advisable to use acrylic putties or cement-based compounds;
- ceiling - both gypsum and acrylic mixtures are allowed. The second option is more suitable for these purposes, since it provides a smoother and more even coating;
- wooden surfaces - only acrylic compounds are used for processing;
- drywall - acrylic putty is most often used. If the air in the room is dry, the use of gypsum mixtures is allowed;
- outdoor work, facade decoration - it is better to take acrylic mixtures and cement-based compounds, which are designed for outdoor conditions;
- surface preparation before painting - polymer and gypsum putties are suitable to create an even and beautiful coating.
Advantages and disadvantages of dry wall putties
Manufacturers of dry putties pack the material in bags weighing from 5 to 25 kg. The shelf life of the powder is 12 months. Before starting work, the required amount of the mixture is calculated. Diluted compounds dry out quickly and lose their properties, therefore one portion is prepared for surface treatment, and the remaining material is stored dry.
The advantages of dry powders:
- convenient packing;
- to prepare the composition, no special knowledge and experience is required; this can be done independently;
- the master can select the consistency of the mixture himself and adjust it;
- long shelf life without temperature restrictions, provided that the package is closed;
- low cost.
The disadvantages of dry material are mainly related to the application technology and storage conditions of the powder:
- applying self-prepared formulations requires certain skills. In the absence of practical experience, there is a high probability of obtaining a short-lived coating with a low level of quality;
- if the technology for preparing the mixture is violated, the material may lose its properties and it will not be possible to use it for its intended purpose;
- homemade formulations are susceptible to rapid drying. After this, the mixture is no longer suitable for use. For this reason, the calculation of proportions causes some difficulties for inexperienced craftsmen. In addition, the mixture must be applied immediately after dilution, which is not always convenient.
Important! It is not allowed to store dry putty in rooms with high humidity, and where water can get on the material. Under such conditions, the powder deteriorates and loses its properties.
Advantages and disadvantages of ready-made finishing putties
Ready-made compositions are polymeric (latex and acrylic) and dispersion. Manufacturers use plastic buckets as packaging for them. This type of putty is in high demand among consumers due to its convenience and simplicity. The ready-made mixtures contain special components. They provide a long shelf life for the material.
The advantages of ready-made formulations:
- the putty is plastic;
- even in open packaging, the shelf life of the material is very long;
- there is no need to calculate the proportions and mix the composition;
- simple application technology;
- wide range of applications (processing of wood, metal and plasterboard surfaces is possible);
- repair time is reduced.
The only drawback of ready-made mixtures is their high cost. Polymer putties are universal. They perform well on concrete, cement, polyurethane and plaster surfaces. They are environmentally friendly, safe for use. Forms an elastic coating. Water-dispersive compositions are suitable for processing concrete and brick, stone and aerated concrete walls. They go well with wood and other types of materials.
Characteristics of gypsum finishing fillers, their advantages and disadvantages
Gypsum-based putties are sold as dry, fine-grained powders. These materials contain special additives. In addition to soluble polymers, putties contain mineral fillers. Most often it is marble flour or quartz sand with a fine fraction. In the assortment of gypsum putties, there are both finishing and starting mixtures, and even universal ones. This type of material is used to mask the joints between drywall sheets and slabs.
Advantages of gypsum-based mixtures:
- environmental friendliness - can be used for surface treatment in residential premises;
- high adhesive properties - the material fits perfectly on all types of surfaces, providing good adhesion;
- excellent permeability - the coating does not interfere with the natural circulation of air, therefore, the likelihood of mold development is excluded;
- affordable cost;
- the material is easy to process - the surface can be sanded.
Important! The scope of application of gypsum compositions applies exclusively to interior finishing work. These mixtures cannot be used in high humidity conditions or outdoors.
Disadvantages of gypsum mixes:
- the mixture sets quickly - the speed of application of the composition must be high, which requires a certain amount of experience and skill;
- high hygroscopicity does not allow the use of putty for exterior decoration. Under the influence of moisture, the coating will collapse;
- it is not recommended to use gypsum mixtures on clean concrete. Before applying, its surface is treated with a special primer;
- short shelf life in an open package - after opening the package, the material must be used within a few days, otherwise it will absorb moisture from the air and become unsuitable for further use.
Features of cement finishing putties, their pros and cons
Cement-based putties are considered the most durable of all existing mixtures. They are suitable for interior and exterior work, as they are resistant to moisture, durable and not afraid of temperature extremes.
In addition to the main varieties, cement putties are:
- heat insulating.
Cement is the main component of the putty, although gypsum, various polymers, lime may be present in its composition.
Advantages of cement compositions:
- simple application technology - the material hardens long enough that
- allows even a beginner to successfully cope with the application of putty and promptly correct mistakes;
- starting mixtures can be used on surfaces with large differences - from 5 to 15 mm;

Many users share their opinions and personal experience of using putties on the forums:
“As an experienced craftsman, I am a fan of Knauf putties, I used polymer mixtures many times and the result was quite satisfactory. Recently I decided to align and update the ceilings in my country house. Usually for these purposes I use Shitrok, but at that moment it was not at hand. I decided to take the gypsum-based Rotband finishing putty and was very disappointed.
After application, the entire surface is covered with scratches and some streaks. This is despite the fact that this is not the first time I have done this! A lot of time and effort had to be spent on grinding. In the end he spat, went to town and bought Shitrok. I had to apply two layers to cover this mess. There are no complaints about Knauf's finishing polymer putties, but I won't touch Rotband again. Too grainy. Well not suitable for a topcoat! "
Evgeny Sidorov, Moscow
“My budgetary possibilities were only enough to buy Bolars polymer finishing putty. In the process of applying, it turned out that the composition dries very quickly, so it is advisable to mix it in small portions. The rest of the putty is very comfortable, plastic, it bridges cracks well. In general, I highly recommend it. "
Marina Fomicheva, St. Petersburg
“I never thought that cheap putties could give such a high quality result. Usually manufacturers shove a bunch of plaster or chalk. Naturally, the effect of such mixtures is not very good. But I took a chance and bought a polymer finishing putty Prospector. This time my instinct did not fail. The material is really high quality. At this price, the putty worked out 200%.
Finishing putty packing - 20 kg. After opening the package, I was a little confused by the grayish color of the powder. After dilution with water, the mixture turned white. The consistency is uniform, easy to apply, perfectly masks irregularities. The best investment is 350 rubles. in the entire history of my renovation ".
