Wall decoration Gypsum plaster: pros and cons

Wall plastered by plaster composition was widely used while eliminating surface irregularities in order to further dyeing or seaming by wallpaper. Such a composition is environmentally friendly, it does not cause allergies, there is no smell, quite easy to use, economically spent, not afraid of fire, has thermal insulating and noise-raising properties.

The ability to maintain a permanent microclimate in the room can also be attributed to the indisputable advantages, since the gypsum quickly chooses an excess of moisture when it appears, and then also easily gives it when the air becomes excessively dry.

Also, the surface previously treated with a gypsum solution is not afraid of rowing nails and twisting the debations.

Most often with plaster composition, walls, ceilings and partitions of residential premises, as well as offices and other buildings of this purpose. It is not recommended to use it for the elevation of walls in the bathrooms and laundries, where high air humidity is present all the time. For these purposes, the waterproof dry plaster mixture is suitable. Also undesirable to use a gypsum solution for alignment of walls in unheated rooms and on open street facades.

Gypsum plaster is applied to a variety of foundations – concrete, foam concrete, brickwork, cement-sand, and other surfaces. The only condition is the absence of susceptibility of moisture.

Please note that if the surface covered has serious damage, it is necessary to first close them with cement, since the plaster coating is applied with a layer of a small thickness and will not be able to hide cosmetic defects.

Gypsum plaster is highly reliable and therefore makes it possible to create roundings on the ceiling area.

The decoration of the walls of plaster plaster due to the characteristics of the material has certain nuances, which will be discussed in detail below.

Peculiarities

Given the technology and observing all the recommendations of the instructions for use, even inexperienced in the plaster business will cope with the alignment of the walls on their own.

First of all it is necessary to prepare a working surface, Namely, clean from dust and possible pollution and pre-primed it. This manipulation will provide better adhesion and a more dense adhesion of the treated surface with the composition. Before applying the composition, determine the desired thickness of the layer of plaster: what it will be thinner, the more liquid should be the composition. Distribute the composition along the wall with a thin spatula, and for alignment, use the rule – a long level rack 1.5-3 m long.

In case of plastering in several layers, before proceeding to the following, let it be drunk by the previous one – this will require at least 3 hours. The first layer distribute and align, moving horizontally, the second layer – on the contrary, vertically.

Gypsum plaster does not form cracks, so the surfaces treated with it provide ample opportunities for decorative processing. To work with concrete bases, a gypsum mixture with primer materials is used.

As the plaster applies evenly, and then acquires the perfect smoothness. For complete drying, the coating requires at least 5 days, after which the surface is ready for final finish.

Types and design

For a long time, the plaster was used as a basis and as an aligning component. Currently, its decorative varieties are widespread, which can safely compete with wallpaper in popularity. It is easy to combine with other types of finishes and, as a result, incarnate the most bold design ideas. It can be smooth or textured.

Decorative plaster can be divided into types of binding substance:

  • Acrylic Elastic, is perfectly applied to a variety of surfaces, suitable for creating decorative elements and patterns with roller or spatula. Present in the market as a finished mixture. Optionally, you can add the desired dye to it. Suitable for work in the bathrooms and kitchens. To apply plaster on the basis, you can use special installations, which is usually done with a large amount of work. Note that to obtain a homogeneous shade and equal invoice, it is necessary to constantly mix the composition so that it does not lose its homogeneity, and if possible, do not interrupt the work longer than half an hour. The resulting surface can be cleaned using soft detergents.

  • Mineral. As a binder in it is used cement. This composition is sold in powder. From the positive moments it is possible to distinguish its strength, resistance to mechanical damage, good sound insulation properties. Allows staining or varnish coating.

  • Silicone Available based on synthetic resin. Plastic, it is easy to apply, at the end of drying, forms a water-repellent film on the surface, which allows it to cover the surface of the surface in the bathroom. Durable, not afraid of mold and fungus. Used exclusively in decorative purposes and does not need to pre-prepare the surface to apply, since it perfectly aligns the walls. The price category of such plaster is slightly higher than in previous species. Sold in a container of various volumes, which is extremely convenient for creating a unique interior design when performing final finishing works.

  • Silicate – manufactured using liquid glass. It is the most durable and durable surface of the coating, prevents the rotting of the walls and the appearance of mold, so it is often used for the external finishing of the facades, although it is sometimes used for indoor work. Does not suffer from temperature drops and wind. It happens in white color or maybe color. Great for porous bases, for example, from foam concrete.

To work with other surfaces requires careful preliminary preparation. Also from disadvantages It is worth specifying a possible change in the color of the coating under the influence of direct sunlight.

In appearance, plaster plaster is divided into the following types:

  • Structural – with the addition of marble crumb or quartz, looks like an inhomogeneous grainy surface. Has high air permeability and resistant to moisture.

  • Textured – demonstrates high adhesion with brick, wooden and simply smooth plastecred surfaces. Easily creates imitation of wood, fabric or stone, there is an opportunity to paint the composition in different colors. This type of plaster perfectly masks irregularities.

  • Venetian – imitates marble or onyx, is often used in the interior decor in the classic style. Application of such plaster requires careful preparation of walls, including reinforcement, putty and primer. After which the paint is applied with a rubber spatula. Each smear requires careful drying. Can be matched or gloss.

  • Flock – new development containing acrylic flakes. Creates imitation of suede or velor, is widely used for finishing ceilings and columns.

I would like to briefly highlight the most popular types of finishes:

  • “Coroed” – contains mineral granules, which, when applied, imitate the pattern, similar to the Wood Beetle path. Used only for finishing works, perfectly falls on the base of drywall, brick and concrete.

  • “Lakes” – contains mineral crumb. As a rule, used for facade works, perfectly falls on any type of surface, pre-purified from contamination and projected. After drying, it is possible to stain in any desirable color.

  • “Fur coat” – Long time ranks first in popularity. Before starting work, thoroughly mix the composition, since decorative elements over time have the property to settle on the bottom of the container.

How to knead the composition?

The recipe for the solution is extremely simple:

  • In deep trough or bucket, clean water is recruited at the rate of 0.5-0.7 liters per 1 kg of powder.

  • The mixture is covered in the container and thoroughly mixed with the use of a mixer for construction works or drills. If there is no such technique, the solution is mixed manually until uniformity.

  • Next, the mixture is allowed to stand for 5 minutes, mix again, after which it is completely ready for work.

  • In comparison with the cement, the gypsum mixture is hardening very quickly, have this in mind, it is irreversible process and it cannot be slowed down.

Tips and recommendations

When carrying out work, pay attention to the following nuances:

  • Gypsum plaster hardens very quickly, so there is no more than half an hour to apply it to the surface.

  • After frozen, the composition is not suitable for work. It is unacceptable to try again to dilute it with water or add new components to slow down the rejection process.

  • In the room where work is carried out, there must be dry air and the temperature was not lower than +5 and not higher than +25 degrees.

  • Make sure there are no drafts, otherwise the result of the work can be spoiled.

  • Before proceeding with plastering, make sure that all the necessary wires are laid (for example, electrical or alarm related).

  • Remember that the gypsum annoys the respiratory organs – it makes sense to protect himself if you spend your work yourself.

  • If there are parts from aluminum or steel in the walls, dismantle them or process themselves against corrosion, since the gypsum has an oxidizing metal object property.

  • At the end of the work, make sure that there are no unwanted traces or stains on the plastered surface. In case of detection, remove them with a special degreasing or water ferry.

  • Ready to final finishing the surface is better to view with good lighting.

  • Refer seriously to the choice of mixture. It is better to give preference to brands that have long been known in the market and having good feedback from buyers.

  • When mixing, the use of a building mixer is allowed for faster and uniform preparation of the mixture.

  • Do not forget to carefully examine the foundation and prepare it for work – the concrete and wooden wall to primer before plastering is needed in different ways.

Subtlety application

Before starting work, you must prepare to store the floor with a protective film in order to avoid the composition of the composition. Carefully read the instructions for the use of powder with which to work.

Before breeding a gypsum mixture, you need to prepare a working surface so that it is the most clean and dry.

It will be right to do this in several stages:

  • Slip pieces of concrete, which are badly held on the base surface;

  • Cold wall – If a deaf sound is heard, concrete became loose, it should also be knocked off;

  • Cracks and sinks are cleaned and poured with cement;

  • Dry surfaces are polished with steel brush;

  • Dust from the walls can be smeared with a soft brush or removed with a vacuum cleaner;

  • The gypsum coating will not hold onto the oil paint, so the latter must be removed using a special nozzle on the drill, pollute the surface of the stain with a rigid steel brush or wipe the solvent, and then apply a layer of gypsum composition;

  • For pre-processing of walls from basalt and granite, specialized compositions are used to surface in the form of an aerosol. After a period of time, the frozen mass is removed from the surface in the form of a film that made all the contaminants, after which the walls are ground with the help of acrylic primer – it is important to prevent the flow from the walls and the formation of air bubbles;

  • In order to improve the clutch of the base and coating, the primer is used, for concrete walls, the “concrete contact” is suitable;

  • Walls made of brick and blocks are processed by the soil, having the characteristics of deep penetration to reduce their hygroscopicity. Before working with a wooden basis, also use specialized funds.

Wall plastered is made using lighthouses or without their use, as well as with the installation of the reinforced mesh or without it.

Work without a lighthouse is held in the case when you need to fill a little wall in the plane or create an external decorative layer. Often this is done with your own hands. With the help of the rule, irregularities on the ceiling and walls – the instrument is pressed in different places, thereby indicating the area of ​​work. Gypsum composition is applied to these areas and smeared over the surface. Next, using the rule, the presence of a lumen between the instrument and the treated surface is determined.

If the tool comes tightly, the same algorithm is practiced in the next section. Similarly, all scheduled areas are processed. An exemplary thickness of the layer will be 2-3 mm, after drying the composition and grinding its surface, you can proceed to the decorative base finish.

Working with lighthouses is appropriate when working with large areas of the foundation, when it is impossible to turn in the machine method. Specialized metal profiles, fishing line or thin cables are used as lighthouses.

Technology Next: Lighthouses are exhibited by level, in order to lay a layer of plastering, as thin as possible. Using the level, create a markup to install beacons. In these places, apply a little solution and attach the beacons without fail with the level. Note that the distance between them should be from 30 to 50 cm – small intervals guarantee a simpler procedure. Try to step between them there is no longer the length of the construction rule. Next, with a loaf on the beacons, the composition is applied to the base and is distributed, the excess is removed.

To carry out this manipulation also use the rule. After the layer of plaster dries a little, its surface must be aligned with a cutter. Keep in mind that it is necessary to start this stage at least after half an hour after the end of work.

After two hours, you can start a spacure surface. For this, the pulverizer splashes the water with give moisture to absorb the top layer of the gypsum composition. When the plastered surface becomes matte again, with a special brush, the moistened top layer is rubbed over the entire wall, filling the slightest irregularities and making the surface with flawless smooth. Then the surface is again well stuffed with a specialized ironing.

If you need to give the plaster glossy shine, after the day it is again wetted with water and quickly rubbing the spatula until the proper effect is achieved. It is extremely desirable to get metal profiles after the work is over, and the remaining pits easily close a small portion of the solution, if it approached the end, you can always make an additional amount.

Over time, beacons can rust And ugly stains will perform on the surface, thereby violating its appearance. If metal profiles did not get off and were not damaged, they can be used next time. The only case when profiles can be left under the layer of gypsum plaster – this desire to lay a tile on top of the plastered base.

The reinforced grid applies when it is necessary to stucify the walls of insufficient strength or in the case when the layer of plaster should exceed 2 cm. In most cases, if the walls are smooth enough, they are treated with a layer of primer. Plasterboard or aerated concrete bases are ground in several layers.

How much driving?

As mentioned above, the solution is seized very quickly – depending on the characteristics of the mixture, the frost time varies from 45 minutes to 1.5 hours. The maximum setting duration is shown by mixtures for hardware application – they freeze in two hours.

To increase the service life and reliability of the plaster layer, it is necessary to give layers as you can dry. The second layer is applied only after complete drying of the first.

When the work is over, the surfaces are allowed to dry for 5-7 days, then plastered walls can be grinding and prepare for decorative finishing works.
