Facade putties are building mixtures specially designed for creating optimally smooth surfaces and the subsequent application of a finishing decorative finishing layer. The terms putty and putty combine one concept and are of German origin, therefore, both designations can be found in different sources. The task of a high-quality putty is not only to level the surface, but also to maximally protect the outer walls from the negative effects of external factors.
Plastering the facade with your own hands
Fine-dispersed facade finishing materials , depending on the purpose, can be represented by compositions of different size and consistency:
Depending on the intensity of the impact of external factors, not only the compositions, but also the technical characteristics of the facade putty mixtures can vary.
A high-quality putty must necessarily be vapor-permeable, moisture-resistant, frost-resistant and sufficiently elastic, which will allow you to complete the work by applying paint, decorative tiles, enamels, mosaics or other finishing materials.
Putties differ in composition and characteristics
The base and finishing mixture can be water-resistant, frost-resistant and heat-resistant:
Putties not only hide irregularities, but also perform protective functions for the facade

Each putty mixture is characterized by a strictly established production technology composition, the main component of which makes it possible to distinguish several varieties that have certain advantages and disadvantages.
| Concrete surfaces with deep cracks. |
Starting, universal and finishing options are available, differing in additives.
|Resistance to temperature extremes, affordable price, ease of work.||Shrinkage occurs, layer cracking may occur.|
| The liquid version evens out and decorates the surface. It is applied with a thickness of 0. |
1-0.3 cm on a properly prepared and primed surface in advance.
|Good moisture resistant material with a high level of strength and elasticity.||Not suitable for quick repair of deep cracks, sanding requires a respirator.|
| The pasty composition has improved moisture resistance and good frost resistance. |
|Ease of use, high level of plasticity and good protective qualities, durability.||Not very affordable cost.|
|Mineral version of the facade mixture based on liquid glass, produced in a ready-to-use form. Suitable for working on surfaces represented by shell rock and aerated concrete.|| High vapor permeability, protects against moisture and dust, has neutral electrostatic properties. |
|Minimal disruption to the application process can lead to cracking.|
|A high level of density of the composition can affect homogeneity the applied layer, therefore, certain skills are required in finishing work.||A budget option with high protective properties.||Significant weight and high density, inconvenient to apply on vertical surfaces.|
| The presence of polystyrene in the composition indicates frost resistance, and latex additives improve water repellency. |
The mixture can be presented in powder and liquid form.
|Durable and plastic material with an affordable price and excellent technical characteristics.||There are practically no disadvantages when using quality material from official manufacturers.|
| Elastic material with high vapor permeability and strength. It is applied in a thin and uniform layer. |
|Plastic and vapor-permeable composition in a variety of colors.||Cost too high.|
Ceresit CT 225. Finishing putty for exterior and interior use
If there is a need to save money on the purchase of factory mixes, it makes sense to prepare the putty yourself:
Homemade mortar, mixed to a homogeneous mass, is characterized by rapid solidification and should be used immediately after preparation;
Plaster-chalk putty, stirring
What are driers
Building chalk, calcium carbonate
It should be remembered that the consumption of self-prepared putty will be higher than when applying ready-made mixtures of factory production ...
To carry out puttying, you will need to purchase some tools that make it easier to apply and get the most even, smooth surface:
Rollers for priming walls
If paint is supposed to be used as a finishing finish for the facade, then the surface must be absolutely even and smooth, so a well-dried layer of putty will need to be wiped with a special fine-grained mesh.
Mesh for grouting putty
Regardless of the type, the putty must be applied to an absolutely clean, dry and pre-primed surface. It is best to use primer options for putty, which will allow you not to plaster the surface.Universal primers can be used on any surfaces, but many experts consider such materials ineffective, therefore they prefer to use special compounds:
Antiseptic primer for indoor and outdoor use
Alkyd anticorrosive primer GF-021 GOST 25129-82 for metal
Alkyd primer for wood "BASE"

Step-by-step instructions for the preliminary preparation of the facade surface for the application of a starting putty layer.
Step 1 . We remove all external facade decorative elements and antennas that may interfere with the priming process.
Step 2. We fix all loose elements on the facade surface or remove them completely.
Preparation of the facade surface
Step 3 . The outer surface is cleaned from dust accumulations with a wet or dry brush with medium hard bristles.
Remove heavy dirt and layers of fat deposits on the surface with a damp cloth. Too strong dirt and paint residues can be removed with solvents, after which the surface is washed with clean water.
Step 5. Using a construction roller, carefully apply the prepared primer solution in a thin but even layer.

Depending on the composition and weather conditions, the process of drying the primer may take from four hours to a day or more.
The starting mixtures are coarser and coarser. They are used for rough finishing of the facade and have good adhesion to concrete, lime, brick and other substrates. They allow filling seams, deep cracks and other large defects.
Starting putty - what is it for and what is it good for
Depending on the initial state of the facade, the working solution can be applied in a layer in a few millimeters or centimeters. It is recommended to apply the starting solution thinly, but in several layers.
In this case, it is possible to obtain a better finish.
Step 1. We dilute cement and gypsum fillers with clean water in the proportion recommended by the manufacturer. Polymer compositions are ready for use and only need to be mixed before application.
Solution for putty
We collect a small amount of working solution on a construction spatula, after which we apply it to the surface with a sweeping and fairly wide movement. During application, the spatula must be pressed firmly enough to the surface at a stable angle of inclination.

Step 3. Smear all beads and irregularities immediately with an empty spatula, and carefully remove excess mixture.
Putty on the walls
After the mortar has set, we perform thorough grinding to get rid of minor defects and makes the surface even and as smooth as possible.
Facades with strong irregularities must be leveled in several steps.
Fast-setting self-made compositions or solutions diluted on the basis of dry ready-made mixtures cannot be stored. They are used as soon as possible.
The main features of applying putty on the wall
The composition of the finishing putty mixtures is represented by fine-grained fractions, due to which the treated structure acquires a smooth and durable structure.
Coarse-grained putties based on quartz sand or marble chips can also be used to create a relief and highly decorative texture of the facade.
In recent years, the most popular way to decorate the facade of buildings is the option in which a putty is used, which is subsequently pigmented with high-quality dye compositions. Quite often, this method is combined with facing work with natural or artificial material.
Leveling the finishing putty
The finishing putty will improve the quality of the subsequent decorative finish
Façade putty can be applied not only manually, but also mechanically, using special equipment. The disadvantage of mechanical application is the lack of the most even application.
Putties on the domestic construction market can be represented by both foreign and Russian manufacturers. Of particular interest to the consumer is the products of the middle price category with high product characteristics.

Putty work can be carried out independently even in the absence of building experience, but in this case the following recommendations cannot be neglected:
Choose a primer and putty from the same manufacturer
