These kinds of materials will highlight flaws.

Furthermore, finish putty contributes to the foundation of the following qualities:

  • Increases strength;
  • Increases adhesion;
  • Get a light coating without spots, which can be noticeable under the finishing material.

Putty acts as a protective barrier when working with drywall; otherwise, it may result in the removal of the previous finish and the gypsum layer.

To remove the flaws that are present on the foundation and will be particularly apparent through thin materials, a painted layer or layer must be applied.

Varieties of material

It is better to state that the final putty is unachievable when considering the sort of ground to be processed and the operating conditions. There are various kinds of compositions with different fundamental components. Plaster, polymer, and cement are the most widely used. These are each one’s benefits and drawbacks.

When considering the type of base to be processed and the operating conditions, it is impossible to achieve the desired result—or, more accurately, the finish putty.

Polymer putty

Latex or acrylic, which are based on polymers, can be applied. Long-lasting and distinctively elastic, the product allows for easy application and even distribution of the solution across the surface. Rapid drying allows for a layer to be as thin as 0.2 millimeters.

The composition is in high demand, which led to the emergence of numerous fakes, and high cost is one of the drawbacks. As per GOST, putty is available; therefore, it is imperative to confirm the availability of the quality certificate.


Gypsum solutions based on sapacle are created in a completed state and are simple to use. varies at a very quick rate of drying, necessitating a certain level of mastery. A thick layer can be applied to eliminate deeper flaws. There is no shrinkage as a result. Only dry rooms should be used; high humidity rooms shouldn’t be used.


The most common kind is distinguished by its low price. It can handle a lot of humidity. It does, however, react to shrinkage and has a lengthy drying period and cracked surface.

A sensible choice for spaces with high relative humidity.

How to choose the right

The finishing line should be determined by the operating conditions and further estimated loads that will be supplied during operation. The following factors must be considered when making a decision:

  • The scope, compounds for external decoration cannot be used for internal and vice versa, the conditions are very different, so different properties are needed;
  • Type of base. Some bases cannot be covered with some types of putty pastes, look at the purpose of the product on the package;
  • Properties required for decoration. Among them are plastic, increased adhesion, simplicity of grinding;
  • Necessary protective characteristics. Sometimes additional protection against aggressive influences, moisture and other. There is a putty finish with certain supplemented properties;
  • What finish are collected after apply. You can leave the layer as the final option for this purpose is selected superfinish type. Superfinite putty stands out with its beautiful aesthetic appearance;
  • Best before date. Когда приобретается готовый раствор, то обязательно сверяют сроки, данные средства не могут храниться долго, теряют свои характеристики. Dry mixtures are sold in bags, can be weighing from 2.5 kg, their storage is longer;
  • Processing area – ceiling or walls. For walls, a large degree of resistance to mechanical loads is usually required for walls.

Features of work with finish putty

As per the instructions, the first step in applying finish putty to the walls is to clean the surface of any pollutants. If mold grows, it is treated to get rid of it entirely. One applies a primer solution. On the surface that has dried, the putty mixture of the initial type is applied.

Once the layer has dried and the base is level, you can apply the finishing white putty. If the mixture is chosen, it is made ahead of time. Adhere strictly to the manufacturer’s recommendations as stated on the packaging.

Applying the composition requires the use of a spatula. Initially, a rubber solution is obtained using a tool and tires. It is then transferred to a long metal spatula with a working area of up to 40 centimeters. After pressing the spatula against the base, carefully distribute the product in two directions: vertically and horizontally. Process the entire region, then.

The spatula shouldn’t have any rusty areas, imperfections, or dirt on it. The composition’s light layer will highlight every flaw.

Afterwards, they start grinding the base. It’s critical to remove all lumps. With a flashlight shining on the wall, it is simpler to find flaws because the shadow indicates their presence.

However, this can also be attributed to inexperience with the master’s composition; novices frequently apply a layer that is thicker than is necessary.

The component utilized in production and the standard of base preparation have an impact on consumption as well. If there are numerous defects, you will need to address them with a solution that takes a lot of work to implement. There are situations when getting the ideal base is necessary before applying a multi-layer coating, which will increase consumption.

If there are numerous defects, you will need to address them with a solution that takes a lot of work to implement.

The putty’s final form aids in creating a smooth, level base. Based on the working conditions and the budget, select the composition. Don’t save, though; because they are so easy to use, high-quality compositions are emphasized by lower consumption.
