Basic types

Currently there are various materials , suitable for cladding the basement of the building, but due to its durability, reliability and quality, it is the plaster that occupies a leading position.

Type of plaster mixture Characteristics and features Standard flow rate
Mineral mixture based on white cement Does not have sufficient elasticity and can crack, allows you to obtain a vapor-permeable coating that is quite easily contaminated. In addition, this species is characterized by a poorer color range. On average, it can vary between 1.5-4.

5 kg / m2.

Acrylic mixture based on acrylic resin. It has good elasticity, which minimizes the risk of cracking, has sufficient resistance to the effects of mechanical properties, is represented by a rich and stable coloration, but is characterized by insufficient vapor permeability. On average, it can vary between 1.5-4.

0 kg / m2.

Silicate or silicon mixture based on liquid potassium glass. Possesses resistance to mechanical damage, good steam permeability, rich color palette and high resistance to mold and mildew. However, the composition is quite difficult to apply, and the presence of alkali makes it not safe for people. On average, it can vary between 2.

0-4.0 kg / m2.

Self-production of plaster mix

Traditionally the most popular among domestic developers and an inexpensive option for basement plasters are a variety of mixtures based on cement and sand. To make such a working solution for plastering the basement of the building on your own, you will need to purchase the following materials:

  • medium-grained sand sifted through a fine-mesh metal sieve;
  • cement mixture of M400 or M500 brand;
  • clean water.

The standard ratio for a part of M400 cement is three parts of sand.

When using the M500 brand, you will need not three, four parts of sifted sand. The amount of water is selected individually, but the finished working solution must necessarily be completely homogeneous, with a characteristic creamy consistency. To increase plasticity, it is recommended to supplement the solution with PVA glue or polymer dispersion.

The base of any structure is often not only a monolith extending the foundation, but can also be represented by various superstructured structures made of foam fiber blocks or bricks. Depending on the version of the basement part, the preparatory measures will have some differences, which must be taken into account in order to get the highest quality and durable plastered surface.

Preparation of a brick base

A feature of the preparation of this type of base surface is the presence of a joint space, which is filled with cement mortar. After a certain period of time, such a solution actively dries up and crumbles, which can manifest itself in the formation of cracks of different sizes, and also sometimes even very significant in depth and width gaps.

At the stage of preparing the brick base, it is very important to thoroughly clean and remove all crumbled or weakly adhering particles and fragments using a narrow construction brush and a metal bristle brush. All cracks formed as a result of such work must be completely cleaned, removing small elements, sand and a layer of dust.

Preparation of rubble concrete base

This type of surface will also require careful preliminary preparation, which will consists in the removal of poorly fixed and heavily worn fragments of masonry, as well as their competent replacement.

The loose element is subject to mandatory dismantling, high-quality cleaning and return to its original place, with fixation on a standard cement-sand mixture.

Preparing the base

Preparing the concrete-cement base

If during the visual Inspection of the concrete-cement basement part, it was possible to identify defects in the form of deep cracks, it is very important to check the strength of their edges and carefully remove all parts that crumble or crumble. If there are signs of even a partial displacement of the foundation, it is reinforced. Small cracks and potholes after preliminary cleaning are smoothed out with a conventional cement mixture.

Priming

All surfaces that need to be protected from plaster, such as window frames, must be pasted over with masking tape

It is possible to obtain a durable and high-quality plaster coating only with the correct application of a deep-penetrating primer in two layers.

If it is intended to paint the basement, then only a facade primer is used for processing, which has the maximum drooping ability. Only the use of high-quality materials and adherence to technological requirements for preliminary preparation of the base for plastering can significantly increase the period of operation and improve the appearance.

Plastering tool

In order to correctly perform plastering work on the basement of the building, it is necessary to prepare in advance not only consumables, but also the entire set of tools through which the measures for applying mixtures will be carried out:

  • construction spatulas different sizes or trowel;
  • construction beacons;
  • metal mesh;
  • lacing for marking;
  • container for working solution.

Plastering technology

Standard it is not difficult to perform plastering activities on your own, but you need to take into account some of the features of the basement of the building, as well as adhere to the basic rules of the technology for performing such work.

Step 1. We apply notches on the surface, contributing to the best adhesion of the plaster mortar to the basement surface.

For this purpose, it is necessary to make notches with a depth of a couple of millimeters using a metal object with a sharp tip.

Step 2. If necessary, we clean out all large cracks and make a high-quality leveling of all protrusions on the surface under the plaster, and also apply a second layer of primer mortar.

Step 3. If the basement part is supposed to be preliminarily insulated, then by means of frost-resistant mounting foam we fix the insulation in the form of sheet polystyrene on the surface.

Step 4. Using special dowels, a mesh-chain-link with cells measuring 20 x 20 mm is installed.

Fixed grid

Step 5. We set the "beacons" that allow not only alignment. foundation base, but also facilitate the work of plastering the basement.

For this purpose, we draw the lines of the boundaries of the plaster layer according to the level, and on the corner part and every couple of meters we set vertically directed pins, between which the threads are also pulled.

Step 6. On the pegs we throw the solution up to the threads, after which we set the "beacons" by pressing into the mixture.

Features of decorative finishing

All further measures will depend on how it is supposed to give the structure's basement attractiveness and durability.As a rule, coloring compositions, as well as facing tiles and decorative embossed plasters are used as a finishing finishing material, therefore, the starting layer must be dried correctly, using a waterproof film coating that can protect the surface from rain and sun for three weeks. At the drying stage, the surface must be moistened with clean water twice every day.

Decorating a basement by creating a relief surface by means of a pre-made stencil is very popular and in demand, when printed, it will be possible to get a drawing that imitates a stone or brickwork. It is fashionable to apply the same pattern with a long and thin object, making grooves in the still fresh plastered surface.

Tips and tricks

Simple recommendations will reduce the time spent and forces to carry out plastering basement works:

  • preparation of the basement part should presuppose special care of the measures taken, including work on beating convex layers, removing bubbles and exfoliated elements;
  • before priming is mandatory thorough removal of dirt and dust deposits with a stiff brush;

    Substrate preparation

  • The plaster layer must be sufficient, at least five thick centimeters, and get the correct geometry of the exposed beacons. If necessary, it is recommended to reinforce the corners with special corner profiles;

    Corner plaster mesh profile

  • The standard distance between the installed "beacons" is not should be equal to or greater than the length of the rule used to level the finishing mixture, and from the extreme "beacons" to the corner part should be about 25 cm;

  • plastering is carried out on a grid, so you need to fill a reinforcing frame base at a distance of a couple of centimeters from the wall, using a mushroom dowel for fixing, at the rate of 15-20 fasteners for each square meter of the treated surface ;
  • To get the best grip, spray with clean water. The second plaster layer can be applied with a trowel or mechanized means.

It is important to note that the full drying of the plastered surface takes about three weeks, after which priming and finishing can be carried out with coloring compositions, but it is strictly forbidden to artificially accelerate drying, using heat guns, building hair dryers for this purpose or other technique.
