Front putty for exterior work - application technology step by step

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.

Classification by purpose

Fine-dispersed facade finishing materials , depending on the purpose, can be represented by compositions of different size and consistency:

  • starting version of the putty, better known as a base or leveling mixture;
  • finishing version of fine-grained putty relatively liquid consistency;
  • decorative version of the putty, allowing to create textured decorative elements;
  • wood putty, used to level and protect wooden surfaces.

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:

  • mixtures with water-repellent qualities minimize the risk of condensation on the surface, which can occur under the influence of rain and vapors. Such a putty is distinguished by a simple and quick application, uniform distribution, compatibility with other types of finishing materials;
  • frost-resistant mixtures are used to seal cracks or chips, and increase the surface resistance to low-temperature conditions;
  • heat-resistant compounds combine in itself excellent adhesive properties and have proven themselves in the processing of surfaces exposed to high temperatures.

Self-preparation of putty

If there is a need to save money on the purchase of factory mixes, it makes sense to prepare the putty yourself:

  • for leveling concrete, relatively flat surfaces, it is recommended to prepare gypsum chalk mixture, mixing three parts of chalk and part of gypsum.With uniform mixing, loose ingredients should be gradually poured into a 5% solution based on wood glue.

    Homemade mortar, mixed to a homogeneous mass, is characterized by rapid solidification and should be used immediately after preparation;

  • for leveling a wooden facade, it is advisable to use an oil mixture, in the manufacture of which a couple of kilograms of drying oil and four kilograms of chalk are mixed, with the addition of a quarter of a kilogram of desiccant. The composition brought to a boil must be cooled to room temperature.

Preparation of the working tool

To carry out puttying, you will need to purchase some tools that make it easier to apply and get the most even, smooth surface:

  • a sufficiently wide brush with a soft bristle or a roller, by means of which the front surface is primed;

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.

Surface preparation

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 primers protect the surface from fungus;

Technology of applying a starting layer

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.

Front putty for exterior work - application technology step by step

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.

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.

Tips and tricks

Putty work can be carried out independently even in the absence of building experience, but in this case the following recommendations cannot be neglected:

  • the surface of the facade must be prepared in advance, cleaned with a brush with metal bristles and carefully primed;
  • moisture-resistant, frost-resistant and embossed putty mixtures can be applied to the facade surface only at positive temperature indicators;
  • at low temperatures, winter putty of the type "Rusean", "Kreps" and "VGT" is subject to use;

    VGT putty

  • the filling technology may vary depending on the type of material, but the simplest and most affordable way is to apply on beacons, which will allow you to get an optimal layer in thickness;
  • for each putty layer of obligation a deep-acting primer solution must be applied to increase adhesion between the base and the applied composition;
