Polymer-cement plaster: application features

Polymer-cement plaster: application features Polymer-cement plaster for interior work and how to work with such a composition. In order to renovate the facade, the construction market offers a wide range of products.

Today we propose to talk about polymer-cement plaster, which not only helps to embellish the walls of the house, but also protects them from the aggressive effects of environmental factors. Due to the large set of positive qualities, the material will become more and more popular.

This decorative type of finish is made from synthetic components that make it possible to create a mixture with distinctive features.

Polymer plasters can easily cope with harsh environmental conditions.

General information

The advantages of this finish

They have the following advantages:

  • They are capable of repelling atmospheric moisture.
  • Let steam from the interior.
  • Withstand mechanical loads.
  • Additionally, they help to insulate the house from heat and noise.

  • Excellent adhesion to all types of materials.
  • There is a huge selection of textures.
  • They sell unpainted white compounds that can be tinted directly in containers or painted after drying on the facade.
  • They can withstand different climatic conditions due to their plasticity.
  • Apply using the same tools as the cement-sand plaster mortar.

Are there any disadvantages of such a tool?

Are there any disadvantages

But such polymer plaster has certain disadvantages, and deal with it is worth it even before buying:

  • The material is not capable of leveling out a huge flaw, and even drops. Everything is applied in a thin layer, which is no more than 0.3 cm. For this reason, first you should level the base well.
  • It will not be possible to create a mixture directly at the work site, and you should buy a ready-made composition.

  • After opening the container with polymer type plaster, you should not take breaks, because the mixture hardens and it will be impossible to bring it back to life.
  • Price - the cost of polymer plasters is much higher than for simple cement-sand compositions.

Now let's consider the types of funds.

Classification and scope of use

In order to create decorative facing, synthetic resins and substances are used. Moreover, there are other components that will increase the elasticity, ductility, strength and other characteristics of the materials.

Depending on the main binder component, several types of polymer plaster can be distinguished.



This mixture is made on the basis of gypsum, and this version of polymer-cement plaster for interior work one of the cheapest among thin-layer plasters. As it solidifies, the solution will become stronger and stronger, and during operation, this characteristic will increase.Manufacturing companies offer dry mixes for sale that need to be diluted with water. they are suitable for exterior finishing of buildings made of materials such as:

  • Concrete slabs.

  • Gas block.
  • Foam block.
  • Brick.

There are several tinted options on sale, but the spectrum is quite small. But to achieve the desired shade or color will turn out through the silicate type of paint.

After perfect drying, the plaster is applied in a couple of layers of paint and varnish material.


Any type of polymer will be the basis here, but the filler is a multi-colored stone crumb that will give a shade polymer plaster. Everything will look very beautiful, and manufacturers offer up to 36 different options. Everything is sold ready-made, and nothing needs to be cooked - just mix thoroughly so that the filler is evenly located. In the process of carrying out the work, it is possible to patch up small potholes or cracks.

After the plaster has hardened, the layer will not be afraid of moisture, and is also resistant to abrasion. Suitable for surface treatment of concrete, cement, chipboard and plasterboard. such a polymer type plaster is used for decoration both outside and inside the house.


This option is the most expensive among other thin-layer polymeric materials. but at the same time, professional craftsmen say that the performance is still at a high level.

Silicone plaster is universal because it is suitable for all types of substrates.


To create this type of polymer plaster, glass is used in molten form. Everything is sold ready-made and tinting. The service life of such a composition is up to 25 years. The specifications are as follows:

  • Polymer-cement plaster: application features Skips steam.

  • Has anti-static properties because there is no need to regularly dust off.
  • Color will not fade.
  • Repels moisture.
  • The material is elastic.
  • Suitable for all types of surfaces.

Let's consider one more tool.


Acrylic resins, which are diluted in water, are used as a base. After hardening, this polymer plaster will not allow vapors to pass through well, but at the same time it will be easy to apply on concrete surfaces. A lot of dust will accumulate on the treated surface, which will lead to frequent maintenance. If there is really a lot of dust, other compositions are used.

Please note that if you have chosen such a mixture, then you should be prepared for the fact that when processing in stages, the boundaries will appear.

Modified compositions for facades

For a long time, materials that were always at hand were used for exterior decoration.If the decor was poorly applied or held, a new component was added to it or could be partially / fully replaced. Thus, the solution has been improved. Today, when there are substances available that can improve the technical characteristics of the plaster composition, and they also conduct certain experiments.

There are also improved compositions for facade finishing, like polymer-cement plaster.


This option is suitable for finishing surfaces made of wood, concrete, brick and buildings with unusual geometric patterns in architecture ... Plaster has anti-fungal properties because it contains lime.

To be used for the rough type of alignment of both facades and wall surfaces indoors. She also skips pairs well. The level of strength is not so good, but still nails hammered into the wall surfaces will withstand, and cracks will not appear.

Polymer cement

The cost of this composition is quite small, and therefore it is considered a budget option for finishing. In order to improve the technical characteristics and properties, a small amount of material in the form of a polymer is added to the cement-sand composition.

Due to this, the plastered surface is able to perfectly pass vapors from the interior. Also, don't worry about the trim catching on fire. Polymer-cement plaster has excellent heat resistance properties.


Professional masters claim that this option is an improved lime plaster. In addition to lime itself, the cerisite will contain ammonia, ammonium salt in the form of an aqueous solution, and oleic acid.

This component makes it possible to greatly increase all the technical characteristics. In addition, moisture-repellent properties will be improved. But this solution adheres poorly to the base and the last applied layer. For this reason, during the work, it is imperative to use a primer composition that increases adhesion and be sure to apply it on thin layers.

Specificity of application for indoor and outdoor work

Both when working with simple cement-sand compositions, and with polymer plasters, you must adhere to all the recommendations that manufacturers usually indicate on the packaging.

Even if plastering with your own hands is not performed, you will still need to control the brigade. For this reason, you need to figure out how everything happens.

Required equipment and tools

You should not buy any unusual tools for applying polymer-type plasters. All that is needed is a trowel and a spatula. If dry mixes were purchased, then a container for water is also required, as well as for mixing the solution.

If a pattern is made as a decor, they buy or it is important to pick up additional tools in the form of a stamp, roller or scrap materials. In the case when plaster was bought like a bark beetle, you will also need a grater to get the corresponding grooves. Do not forget to calculate the required amount of plaster before buying. This requires knowing the total surface area to be treated. To calculate the amount of material, you should know about the consumption of the mixture.

Manufacturers indicate such numbers on the pack.

Preparatory stage

When the materials are purchased and you have enough polymer-cement plaster, you can start preparing. As mentioned earlier, polymer varieties of plaster solutions are used only as a decorative topcoat, because the base should be prepared in this way:

  • Polymer-cement plaster: application features Remove the old coating.
  • Remove dirt, dust and grease stains.
  • If there are cracks, huge damage and horizontal / vertical differences of more than 0.

    5 cm, perform a rough plastering.

  • Perfectly dry treated surfaces.
  • Walls should be treated with a primer, which is chosen for the selected type of polymer plaster.

Good advice! Do not skip the priming step, and such formulations can reduce the negative impact from the external environment.

Preparing the solution

At this stage, everything is quite simple.

If purchased dry mix, it should be diluted in water. The proportions are indicated on the packaging and this recommendation is adhered to unconditionally. Otherwise, the solution will turn out to be either very liquid, which means it will begin to creep from the base. Or it will become very thick and difficult to apply. Be sure to allow the prepared solution to infuse, and then stir it again and proceed to surface treatment.

With the finished mixture, everything is much easier, and after hiding the container, the polymer plaster should be thoroughly mixed and immediately started to work. But take into account the solidification time of the solution, and you should not take long breaks, because otherwise the mixture will be completely and irrevocably damaged.

Technology and application method

Different technologies are used depending on what drawing is required. The standard procedure is something like this:

  1. A small amount of the mortar should be taken with a trowel onto a spatula.
  2. After smooth movements spread the mixture evenly over the entire surface, and you can work from bottom to top, and vice versa.

  3. When the solution hardens a little, you can start drawing on the wall using the appropriate tool. If a simple, even layer is required, take a trowel and remove any roughness.

That's all, as you can see, the process is very simple and any person can handle it.
