Polymer putty for internal work: differences from gypsum, types and features of use, pros and cons of the composition

Selecting the appropriate materials for an interior renovation project is essential to its success. Putty is a necessary ingredient in the procedure since it smooths and prepares surfaces for painting. Of the different kinds available, polymer putty is one of the most widely used. Gaining an understanding of its types, differences from gypsum putty, and application will help you get the best results possible for your interior painting project.

Polymer putty has a reputation for being both flexible and long-lasting. Polymer putty conforms to small movements in the building structure, unlike gypsum putty, which is more rigid and prone to cracking over time. Because of its flexibility, it’s a great choice for surfaces like modern home ceilings and walls that could occasionally expand or shift slightly.

Polymer putties come in various varieties, each intended for use in particular situations and tasks. Certain products are designed to dry quickly and sand easily, which makes them perfect for projects that move quickly. Some have improved adhesion qualities that guarantee a solid bond with a variety of substrates, such as plaster, metal, and wood. The final look of your surfaces and how easy it is to apply are both greatly influenced by the type of polymer putty you choose for your project.

Polymer putty has several benefits, such as its resistance to cracking, ease of application, and suitability for a variety of surfaces. It does, however, have certain shortcomings. For example, the cost of polymer putty may be higher than that of gypsum putty, and the drying time may change based on the particular formulation and the surrounding circumstances. Even with these drawbacks, the advantages frequently exceed the disadvantages, particularly in long-term projects where durability is a top concern.

In conclusion, polymer putty is a dependable and adaptable material for interior construction. For many renovation projects, its flexibility, variety, and durability make it the best choice. Your interior surfaces will have a smooth, polished finish if you know how it differs from gypsum putty and select the right kind for your requirements.

Technical characteristics of polymer putty

Plasticizers are used in addition to polymers to make polymer putty. Chalk and talc are among the substances that make up its constituents. Special additives ensure the composition’s ideal fastening, and a range of staining pigments are responsible for the products.

The purpose of the polymer putty

The purpose of putty is to level the ceiling and the walls’ surfaces.

These kinds are called mixtures:

• Leafing;
• Final;
• Universal;
• Special.

If needed, the leveling composition is applied to create a black finish.

Putties with a similar polymer base are intended for walls; use a thick layer to prevent damage. They typically do not slide on a plane, do not permit shrinkage, hold their shape well, and, once hardened, produce a persistent coating.

The finish putty

The final putty, which is based on polymers, removes minor flaws and "hides" microcracks to create a smooth surface. It is applied on top of the black mixture and used as the last step in leveling the wall’s plane.

The universal composition can be used as a starting mixture or as a substitute for white finish putty. Putty, according to some sources, can conceal some flaws but is obviously inferior to products with a clear specialization (for instance, thinner than the layer, longer drying time, less plasticity).

Special putty is made up of auxiliary ingredients that give the composition the typical qualities needed to address particular issues. A container is indicated along with comprehensive details about this product’s attributes.

Unlike gypsum-based substitutes, polymer putty has special advantages for interior work, such as increased flexibility and crack resistance. This article describes the many kinds of polymer putty that are available, highlights the main distinctions between them and gypsum putties, and outlines the particular uses for each. We’ll also consider the benefits and drawbacks of polymer putty so you can decide wisely for your home renovation projects.

Instructions for using polymer putty (step by step)

When it comes to finishing layers, proper application and technological adherence are the primary determinants of their strength and quality.

As a result, just like with any other building material, the most important thing to remember is to work with putty that is produced at the polymer base competently and alternately.

Preparation of the plane

The base that putty will be applied to needs to be properly prepared. It needs to be cleared of debris, pollution, and fat deposits; if any are present, they must be thoroughly cleaned and degreased with an alcohol-based solution.

primer

Primer

The cleaned plane must be opened with a mineral primer before being worn. Doing this well means not making any mistakes.

The base will be optimally primed when the second layer is applied after the first has completely dried.

Kneading dry putty solution

If a dry putty composition is to be used, it must be made to the required consistency. To do this, mix dry powder with clean, room-temperature water, according to the directions on the container.

The putty is polymer

1. At first, it must be well mixed with a spatula or trowel, and then, when the composition becomes thick, it is better to apply special. Construction nozzle – "mixer".
2. After mixing, it is necessary to let the composition brew for 10-15 minutes., and then – mix again, observing the composition of the solution.
3. If it is liquid, then a little powder should be added, and if, on the contrary, dense, then add water.

Coating the plane with polymer putty

To apply polymer putty more comfortably, use a trowel or spatula with a medium width. It is a true technology to use two spatulas.

A small amount of composition is placed on the wide spatula’s edge, and the putty needs to be moved to the base while the tool is held at an acute angle to the plane.

• The thickness of the formation should not exceed 3 millimeters, otherwise the putty will be uneven to dry, change its shape, etc.
• During the period of work, you need to carefully observe the uniformity of the layer, trying to form it the smallest and direct.
• The key polymerization of the material takes place for about 300 minutes after application if there is room temperature outside.

Logging the plane

The best way to clean the plump layer after this time is to use construction sandpaper, which has a slight dispersion. Furthermore, rubbing the surface with a specialized grater is permitted.

It is necessary to wipe using consistent circular motions while attempting to maintain the same amount of pressure on the spatula. Generally speaking, you just need to grind as normal to avoid ruining the putty layer—you don’t need to press too hard.

Crucial! It is preferable to apply the second layer of putty made of polymers if the final finish is to be painting or incomplete decorative finishes, i.e., when putty must form a very even plane.

This should be carried out about 240 minutes after the initial layer is applied. After a certain amount of time for it to dry, it can be cleaned, and then the material is applied once more.
