Dry construction mixes on a plaster basis. Features of the gypsum mixture. silicate plaster mixes

Regardless of the type of repair (cosmetic or major), a process such as plastering walls is required. It is safe to say that these works are the most time-consuming and expensive. They cannot be performed without the use of special dry mixes.

There are several types of this finishing material, but the most high-quality, reliable and easy to use are gypsum plaster mixes.

As the name implies, the basis of the material is gypsum.

In addition, it is also possible to distinguish the following main components that make up gypsum plaster:

Filler. Differs in easy structure and consists of small fractions. The presence of a filler ensures the stability of the form and structure of the plaster. Thanks to this, gypsum plaster mixtures are extremely economical in consumption.
Polymers. They give the mixture properties such as elasticity and impermeability. In addition, the presence of polymers guarantees a high rate of adhesion of the mixture to the working surface.

The composition of gypsum plaster allows you to use it for such purposes:

Masking and sealing a variety of defects and irregularities on the surface.
Formation of slopes and corners (see).
Alignment of walls that have a littered corner.

Note. Plaster gypsum mixture is produced in the form of a dry powder, packed in convenient and sealed bags.

Main advantages

This is clearly seen in the table below:

Types of plaster	Cement	Gypsum	Result
Properties
light weight	–	+	The mixture perfectly keeps on the surface, does not form sagging, it is possible to use the machine method of laying, high speed
No need for post-treatment of the mixture on the surface	–	+	Immediately after the putty layer has hardened, surface finishing can begin.
Short curing time	–	+	The time required for finishing work is significantly reduced
low density	–	+	Provides minimum consumption of working material
Does not shrink	–	+	Cracks do not form after the mixture dries
Environmental friendliness	–	+	Promotes a healthy and healthy indoor climate

Note. From the foregoing, it follows that gypsum plaster mixtures are the most economical and convenient type of dry plaster, the price of which is affordable for every buyer.

Usage

You can familiarize yourself with the preparation process from the instructions printed on each package.

Stages of work

First of all, you should pay attention to the temperature inside the room. It should be within + 5 + 30 degrees Celsius.
Before starting finishing work, it is necessary to prepare the surface: Having cleaned it of dust, old plaster (see How to remove old plaster from walls without problems), dirt.

It is also required to remove all foreign objects:

Nails.
Hooks.

Advice. If it is not possible to remove them, they must be treated with a special anti-corrosion liquid.

The surface on which the gypsum plaster mixture will be applied must be treated with a primer:

If the work surface is highly absorbent, such as aerated concrete or brick, it will have to be primed several times.
This is necessary in order to ensure good adhesion of the mixture to the surface.

Now you can start preparing the solution:

To do this, the powder from the bag is poured into a deep container and poured clean water at the rate of 0.6 - 0.8 l of water per 1 kg of dry powder.

If such devices are not available, you can interfere manually. I would like to note that the prepared mixture must be used within 30 minutes.
Otherwise, the solution will begin to dry out and become unsuitable for further use.
It should also be noted that it is also impossible to allow foreign components to get into the finished plaster.

Note. This can disrupt its composition, which as a result will lead to the fact that it will lose its properties.

The gypsum plaster mixture is applied to the surface with a layer, the thickness of which varies between 50 - 79 mm:

Work must start from the top down. After a layer of plaster has been laid, it should be leveled.
For this you can use special tool- a rule that has the shape of the letter h. After an hour, remove excess plaster as a rule.
You can finally level the plastered surface with a construction spatula with a wide base.

If no traces remain, it must be abundantly wetted and rubbed with a sponge grater. You need to do this with gentle circular motions.
To achieve the most even surface of the plaster, this procedure can be repeated after approximately 24 hours.

Note. One of the advantages of this solution is that plastering with a gypsum mixture eliminates the need for subsequent processing of the working surface.

For quick and high-quality drying of the solution, it is necessary to completely eliminate the presence of drafts in the room.
In addition, direct sunlight should also not be allowed to hit the surface.
The final stage of work is to ventilate the room. Thus, excess moisture is removed from it.

The video in this article will clearly acquaint you with the stages of working with gypsum plaster.

What to look for when choosing a material

When buying gypsum-based plaster (gypsum plaster mixes), experts recommend paying attention to its manufacturer. In the construction and finishing materials eat pretty big choice these kinds of mixtures. achieve positive result is possible only if the product is produced by a well-known company whose products received positive reviews users.

Gypsum plaster mixtures are produced by the following brands:

Baumit;
Knauf (see Knauf facade plaster: material characteristics);
Litox;
Polirem;
ArtEko, etc.

According to experts, Knauf gypsum plaster mixtures are of the highest quality and most reliable in use. It can be easily used by both experienced and novice craftsmen.

Gypsum-based plaster produced by this manufacturer has the following positive properties:

Uniform connection of dry powder with water.
Can be used for finishing different surfaces: brick, their gas - or foam concrete, tiled, concrete, etc.
No shrinkage process, and, as a result, the formation of cracks after drying.
Economic consumption of working solution.
The most even distribution on the surface.
Minimizing the time required for finishing work.
Environmental friendliness.

Note. It is also important that the Knauf gypsum plaster mixture has such a property as sound insulation. This is extremely important. If Finishing work held on premises panel house where sound isolation is poor.

At the end

This became possible due to the fact that in the production process such an environmentally friendly natural component as gypsum is used as a basis.

As a result of the use of special additives, gypsum plaster mixes produced by this brand do not spread on the surface. This makes it possible to use them when working on an angled surface, finishing or leveling slopes and corners.

By choosing the plaster of this manufacturer, you can be completely sure that the mixture will fulfill all the functions assigned to it, and the work surface will have an attractive appearance for a long time.

If you need to level the surface of the walls in the room or update the facade of the house, wall plastering is one of the most inexpensive and popular ways. Of course, getting started, you must first familiarize yourself with the types of plaster (especially when repair work there is not enough experience), because choosing the wrong mixture can ruin the final result. In this article we will tell you how the plaster mixture is prepared on cement base and dry gypsum plaster, as well as which type is suitable for walls.

Wall plaster

Compare cement-sand, lime and gypsum mortar for plastering walls according to specifications.

Gypsum plaster

The most popular now are dry mixes for plaster on plaster base. Their main advantage is a very simple application process. Such plaster is sold ready-made, you don’t have to mix anything, you just need to dilute it with water in the required proportions.

The most popular plaster mixture is from Knauf-Rotband, Volma Sloy, Forman 10, Founding Gipswell, Prospectors. In terms of quality, they differ little from each other, but some types cannot be used in wet areas.

Separately, it is worth talking about universal mixtures for wall plastering from Knauf-Rotband. The price for a bag of 30 kg is 360-390 rubles, which is more expensive than all similar options. On sale there is also packing of 5, 10, and 25 kg.

This mixture has been produced for half a century in Germany, and in Russia it appeared 20 years ago. It has become so popular that the name "Rotband" is used by some to refer to any dry gypsum plaster mixes.

There are others gypsum plasters from Knauf-Goldband and HP START, but they are not in demand due to their high density.

"Rotband" has the following characteristics:

Consumption 8.5 kg/sq. m. with a layer of 1 cm. One standard bag is enough to level 3.5 sq. m.
The maximum layer thickness is 5 cm (only 1.5 cm on the ceiling, and if the height differences are greater, then alignment is done using).
Minimum Thickness layer - 0.5 cm (1 cm when laying tiles).
The average drying time is 7 days, depending on humidity and thickness.
Suitable for plastering walls and ceilings made of concrete, brick, polystyrene foam surfaces.
This mixture is not suitable for sealing joints between drywall sheets. For this, gypsum-based putty is used - " Knauf Uniflot". Read more about in our article.
Recommended for use in rooms with normal humidity air, can be used in the kitchen or in the bathroom.
Color - from white to gray or even pink. It depends on the amount of natural impurities, and does not affect the characteristics of the material.
Shelf life - 6 months.

You can apply a thicker layer on the walls after the first layer has completely dried. maximum thickness. On the ceiling, applying more than one layer of plaster is unacceptable.

Among the main advantages of the mixture "Rotband" are the following.

Getting a smooth surface.
The absence of cracks even on a thick layer of plaster (subject to compliance with the technology).
The consumption of the mixture is two times less than that of cement-sand types.
Possibility of applying a layer up to 5 cm in one go without splashing the surface.
The solution does not lose all moisture even on porous substrates or at elevated temperatures, which ensures uniform drying without delamination and without cracking.
The composition does not contain harmful substances, completely safe.
Due to the addition of polymer additives to the composition, the mixture provides enhanced adhesion, which allows it to be used even on the ceiling.
The composition of the mixture includes special additives to increase the working time with gypsum mortar.

To obtain the optimal consistency, the dry mixture is mixed with water in proportions of approximately 2: 1, i.e. 15-17 liters of water should be used per 30 kg bag. For thorough mixing, use the mixer nozzle on the perforator.
The video shows an example plastering works with the help of "Knauf Rotband":

Cement plaster mixture

The cement-sand mixture for plaster has the following composition:

1 part of cement m-400;
3-5 parts of sand (if the cement is m-500, then you can increase it to 7 parts of sand).

Usually, when cooking, all the elements are added “by eye”. You can use the following instructions.

The preparation of a solution for plastering walls begins with sifting sand. This will require a sieve with cells of about 4 mm; for dry sand, a finer mesh can be used. When the sand is ready, proceed to the manufacture of the solution. To do this, pour 2.5-3 liters of water into a 10-liter bucket.

To make the solution soft and plastic, you can add a little detergent to the water.

Put three parts of cement into the mortar container and mix it thoroughly with a mixer.
While mixing the solution with a mixer, add sand until the container is full. Start stirring the solution at low speed so that the liquid does not splash out.
As a result, the solution should turn out to be a viscous consistency, so that when the mixer is pulled out, a hole of 2-3 cm remains.

One batch is enough for approximately 1.5 square meters of plaster. m. walls. Basically, the consumption of the mixture depends on the thickness of the applied layer, so if you want to avoid overspending the material, then you need to buy the thinnest beacons, from 3 mm.

Dry mix cement based

If there are no plans to mix the solution yourself, you can buy a ready-made mixture in dry form, which is simply diluted with water.

For example, the following types are on sale:

"Vetonit TT";
"Volma Aquasloy";
"Magma";
Plaster and repair putty "CeresitCT 29";
For facades: Knauf Unterputz, Sokelputz, Grunband (with expanded polystyrene granules), IVSIL GROSS.

Cement-lime mixtures

Cement mortar in its pure form is not used so often, because it has poor adhesion and increased cracking. In addition, not everyone has the opportunity to use expensive dry mixes, so lime mortar plaster is a good alternative. This is very economical option a mixture with which it is convenient to work due to its plasticity.

Also, this option is good for use in private homes due to bactericidal properties - this additional protection from fungus. Lime mortar is chosen mainly for rough wall finishing in rooms with normal and low humidity. Unlike cement mortar, a lime-based mixture is well suited for plastering on shingles, as it adheres well to a wooden surface.

The disadvantages of this mixture include low grade strength, in contrast to the solution based on Portland cement. But this drawback does not play a special role; for plaster, compressive strength is not so much important as good level adhesion and plasticity.

Composition lime mortar for plaster:

1 part cement;
½ part of slaked lime;
5 parts of sand;
300 ml liquid soap.

The mixture turns out to be very elastic and keeps well on the wall; after drying, cracks do not appear on the surface. Liquid soap adds a pleasant smell and increases elasticity.

Cement-lime mortar for plaster can be prepared in another way:

1 part lime sour cream;
2.5 parts of sand;
0.12-0.25 parts of cement (depending on the amount of lime).

Best to take quicklime and extinguish it yourself. 50 kg will require 13 buckets of water. Please note that lime will increase by 2.5-3 times during slaking, so this work is done in a barrel of the appropriate volume.

This composition will adhere well and keep on the wall, level with the rule and rub well. Plastering costs 250 sq. m. such a mixture will cost about 22,200 rubles. (per material):

3 cubes of sand - 2000 rubles;
quicklime 800 kg - 19,000 rubles;
cement 150 kg - 1200 rubles.

If we compare the costs with the Rotband plaster, then the same area would take 3-4 thousand rubles more.

Dry mix based on lime-cement

You can purchase a ready-made dry mix on a lime-cement basis.
The most popular types are:

"Knauf Sevener" (universal mixture);
"BEST";
“Founding STARTWELL” and “FLYWELL”;

Facade plaster mixes

In private houses, in addition to interior decoration, required exterior finish walls. Many owners unknowingly or for the sake of economy plaster facades with the same mixture that was used for interior decoration. It is strongly discouraged to do this, because for external walls requires a mixture that can withstand exposure environment and yet not collapse. Below we give a list of good plaster mixes for facades.

Mineral plaster mixes

Mineral mixtures are produced on the basis of cement, therefore, there is a marking on the packaging - “Polymer-cement mixture”. Thanks to such a component as a redispersible powder, these mixtures have high adhesive qualities. Mineral mixtures are sold dry in bags.

mineral plaster
Specifications:

low cost;
resistance to fire;
moisture resistance;
good strength;
high vapor permeability;
long-term operation.

Acrylic-based plaster mixes

Synthetic plaster mixes are made on the basis of acrylic dispersion. Sold already in finished form in a liquid state and do not require additional preparation.

Acrylic plaster
Specifications:

increased resistance to mechanical stress;
moisture resistance;
high adhesion to various surfaces.

silicate plaster mixes

The basis of silicate mixtures is potassium liquid glass. Silicate mixtures are produced in liquid form, ready for use. This type of mixture is ideal for finishing insulated walls mineral wool.

silicate plaster
Specifications:

excellent elasticity;
good water resistance;
good strength.

Silicone plaster mixes

As you can easily guess from the name, the composition of this type of mixture includes an expensive material - silicone. For this reason, silicone mixtures are very expensive, but the price is well compensated by the merits of this material.

silicone plaster
Specifications:

excellent resistance to moisture;
long-term operation;
excellent adhesion;
high elasticity;
easy installation.

We examined the main types of plaster for walls, ceilings and facades. We advise you to carefully study the characteristics of each of them and choose the most suitable option. You can either buy a ready-made mixture, or cook it yourself according to the proportions above.

In our renovation with you, we settled on the fact that in the bathroom. To complete the process, it remains for us to wipe the seams and putty the ceiling. So we got to a little unusual variety cement mixtures are polymer-cement putties and polymer-cement grouts.

These mixtures are similar in composition to tile adhesive- the same gray or white cement, the same cellulose thickener, polymer. But as a filler, either finely dispersed quartz sand(fractions up to 0.3 mm), or marble or limestone flour with the same particle size.

Polymer cement putties

Let me remind you that puttying is the final leveling of the surface, with a layer of 1 mm to 1 cm, before subsequent plastering, painting, wallpapering, etc. Polymer cement putties are used as in facade works, as a finishing layer on lime-cement plasters, and when leveling surfaces inside dry and damp rooms. When working with these putties, it must be remembered that the performance of the solution based on them is 2-3 hours. In this case, the coating is quite hard - the skin must be chosen larger.

Polymer cement grouts

A variety of polymer-cement putties - grout for tile joints. Grouts are divided into white, gray and colored. White and gray in composition are completely identical to cement putties. In the production of colored cement, an inorganic pigment is introduced into white or ordinary cement. Grouts play both a decorative role in the tile coating and a protective one. Thanks to the polymer introduced into the cement, as a rule, it is a type of vinyl acetate (remember PVA glue), the grouts do not let moisture into the tile joints, thereby protecting the adhesive layer.

Grout compositions represent limitless possibilities of design imagination. The picture shows a dark brown grout, into which bronze powder was introduced during mixing. The effect is a dark brown metallic color.

White grouts can be tinted with tinting pastes, getting completely unusual colors. By the way, in the mosaic, cement-based grouts play the most important role, also acting as adhesive solution: The mortar holds the tiling map grid. Ground marble or limestone is used as a filler in grouts, as quartz can scratch the glaze of the tile.

You can use white or gray putty as a mosaic adhesive, but in this case it is necessary to add acrylic latex (or acrylic primer) to the mixing water.

Gypsum-based mixtures

These are the lightest in weight and easy-to-work formulations. Their only drawback is the possibility of use only inside dry rooms.

Gypsum is known to be a fast-setting and hydrophilic (water-absorbing) compound. The same polymers are introduced into gypsum-based mixtures in order to reduce water absorption and increase adhesion (adhesion strength), as well as inhibitors - substances that slow down the gypsum hardening reaction. The simplest example inhibitor - food or technical citric acid. If, when mixed with water for 1 kg of gypsum, you add 10-20 grams citric acid, then the gypsum mass will slow down its hardening to 30-40 minutes.

Gypsum mixtures are divided into:

Gypsum putties

They consist of a gypsum binder (hereinafter we will call it gypsum, although a mixture of alpha gypsum and anhydride is used in the production), quartz or limestone filler, cellulose thickener and a redispersible polymer. Gypsum putties can be applied in layers from 1 mm to 1 cm.

Attention! Gypsum is calcium sulfate - CaSO4. When painting a surface leveled with such a mixture, it is necessary to use acid-resistant paints. And, accordingly, observe safety precautions: gypsum, even in a small wound, causes very unpleasant sensations.

Gypsum plasters

Dry mixes that have earned the highest recognition from professional builders. They are light, easy to use, do not shrink (unlike lime-sand-cement putties), quickly harden on the surface and have a fairly high performance - from 30 minutes to 1 hour.

You can make the simplest gypsum plaster in your kitchen: take 10 kg of gypsum, 1 kg of slaked lime, 50 grams of citric acid, mix it all with water and mix until a thick sour cream is obtained.

With the finished mixture, you can close up the strobes, level the wall or ceiling. Although industrially prepared plasters also contain fractionated sand, a cellulose thickener and a redispersible polymer. In some compositions, to give the plaster volume and lightness, expanded perlite or vermiculite is added - light, weightless sands. The average consumption of such a plaster is 7 kg / m2 with an application layer of 1 cm.

Gypsum-based mounting adhesives

If we want to glue a sheet of drywall to the wall, mineral insulation, styrofoam sheet, best suit us mounting adhesive based on gypsum. The composition is similar to the composition of tile adhesive, with the exception of the main component: gypsum instead of cement.

Gypsum floor mixes

Putties based on a polymer binder

They differ from the above types of dry mixes in that they do not contain either cement or gypsum. These are fillers, almost 100% consisting of aggregate - fine limestone or marble flour, cellulose thickener and redispersible polymer.

Putties of this type are very convenient in application and subsequent processing (sanding), suitable for subsequent painting or wallpapering. In diluted form, they have a working capacity of up to 24 hours. But these putties are not intended for leveling surfaces for laying tiles. Putties based on a polymer binder are used only inside dry rooms as a finishing layer for leveling the surface and are not used without further coating.

The main components of gypsum dry mixes are: gypsum binders, fillers, functional additives.

Used as a binder in gypsum mixtures building plaster based on calcium sulfate hemihydrate. Less often they are used in a mixture with anhydrite (especially for plastering) to ensure necessary deadlines setting. High-strength (experts say “high-quality”) gypsum and anhydrite are used in the compositions of self-leveling mixtures. The use of these types of gypsum binders in flooring compositions is explained by the special requirements for the strength of such solutions.

The filler is introduced to reduce the cost of the product, but most importantly - to prevent cracking during operation. In addition, its use improves the manufacturability during application. As aggregates in gypsum mixtures, quartz sand is used, as well as limestone flour, dolomite flour, chalk, ash. Perlite is used in the compositions of light plasters - for example, in mixtures such as HYPER PLAST (the name of this mixture comes from a combination of the words Gypsum and PERLITE). IN certain types putty mixtures, the use of mica is recommended. The dispersion of aggregates is determined by the type of gypsum mixture: quartz sand and limestone sand are used with a dispersion of up to 0.8-1.0 mm. When choosing fillers Special attention given to the granulometric composition: there should be approximately the same ratio of aggregate fractions.

Hydrated lime Ca(OH)2 is added to gypsum mixtures to improve plastic properties, reduce shrinkage and slow setting.

Functional additives slow down the setting speed of the gypsum mixture, increase its water retention, mobility, plasticity, adhesion strength, and reduce the risk of cracking.

Setting retarders are important functional additives that provide an increase in the survivability of the gypsum mortar mixture. It is known that gypsum binders quickly set, and the solution to the problem of increasing survivability is right choice special additives - setting retarders.

Cellulose fibers are introduced into the composition of gypsum mixtures to reduce cracking and shrinkage.

These are the lightest in weight and easy-to-work formulations. Their only drawback is the possibility of use only inside dry rooms.

Gypsum is known to be a fast-setting and hydrophilic (water-absorbing) compound. The same polymers are introduced into the gypsum-based mixture in order to reduce water absorption and increase adhesion (adhesion strength), as well as inhibitors - substances that slow down the gypsum hardening reaction. The simplest example of an inhibitor is food or technical citric acid. If, when mixed with water for 1 kg of gypsum, you add 10-20 grams of citric acid, then the gypsum mass will slow down its hardening to 30-40 minutes.

Gypsum plasters

You can make the simplest gypsum plaster in your kitchen: take 10 kg of gypsum, 1 kg of slaked lime, 50 grams of citric acid, mix it all with water and mix until a thick sour cream is obtained.

Gypsum-based mounting adhesives

If we want to glue a drywall sheet, mineral insulation, a foam sheet to the wall, gypsum-based mounting adhesive is best for us. The composition is similar to the composition of tile adhesive, with the exception of the main component: instead of cement, gypsum.

Gypsum floor mixes

Self-leveling (self-leveling) compositions for pouring floors in various layers. The composition and principle of action are discussed in the first part of the article (see also the article Leveling the floor).

Putties based on a polymer binder

Plaster mixtures in construction are used very widely. Such compositions can be used for interior walls, ceilings, facades, columns, etc. The types of such mixtures on modern market there are several. And one of the most popular varieties is plaster based on gypsum. Many companies produce such compositions. However, some brands of gypsum mixtures are, of course, the most popular among consumers.

What criteria are used to evaluate

When choosing gypsum plaster, first of all, you should pay attention to its characteristics such as:

maximum allowable layer thickness;

drying time;

base type;

Gypsum plasters are usually used only for finishing indoor surfaces. For facades, such compositions are not used. In most cases, manufacturers also recommend using such products only in dry rooms.

The best plasters

Most of the products of this type sold on the market today are of good quality. But still, the most popular gypsum plasters among consumers are:

"Rotband".

"Gipswell".

Bergauf.

"Prospectors".

"Eunice Teplon".

Plasters "Rotband"

Dry mixes on this brand belong to the group of universal products. The composition of Rotband plasters, among other things, includes special additives designed to increase their adhesive properties. Also gypsum mixtures "Rotband" contain all sorts of natural impurities that determine their color. Depending on the manufacturer, such compositions can be:

pink.

In this case, the pink Rotband plaster is considered the highest quality. Such mixtures are produced by the Knauf Gips Chelyabinsk and Knauf Gips Kolpino enterprises. White and gray gypsum plasters of this brand are produced in Krasnogorsk, Krasnodar Territory and Astrakhan region. Such funds can also be considered of sufficient quality. However, when using them, you should still be a little more careful. White and gray plasters "Rotband" flow down the wall a little, as a result of which horizontal waves can form on the surfaces.

Consumer reviews

The advantages of Rotband plasters are primarily attributed by consumers to their plasticity, strength and the ability to achieve the smoothest possible surfaces. Working with such compositions, judging by the reviews, is very easy, and on the walls in the future, such a finish lasts as long as possible. Also, consumers consider the advantages of Rotband plasters, of course, their excellent adhesive qualities, as well as minimal shrinkage.

Some disadvantage of such gypsum mixtures, consumers consider not too long "survivability" of the solution. It is necessary to work with such plaster as quickly as possible or not to knead a very large amount of it at the same time. Also, the disadvantages of "Rotband" consumers include quite high cost.

Mixtures "Volma"

A feature of the plaster of this brand is considered primarily plasticity and the ability to "breathe". This mixture is produced by the domestic company Volma, founded back in the 40s. There are several types of this plaster on the market today, slightly different in composition:

"Volma-Sloy", designed for use in rooms with temperature fluctuations.

"Layer Titanium" and "Ultra", the most resistant to cracking.

"Canvas" with mineral additives that maximize adhesion.

"Plast" - universal, very plastic.

"Lux" - designed for work on foam concrete.

Also, this manufacturer produces gypsum dry building mixes intended for machine application: Gypsum-Active with additives that provide increased moisture resistance, and crack-resistant Gypsum-Active Extra.

Reviews about mixtures "Volma"

The most popular type of plaster of this brand among consumers is Volma Canvas. It is about this gypsum binder mixture that the Web has the best reviews. The advantages of Volma Holost formulations are primarily attributed by consumers to ease of application and versatility. This mixture, as noted by some masters, can be used to level walls, texturing under decorative plaster and even, for example, sculpting bricks.

The masters consider the main disadvantages of Volma Canvas to be too fast setting and the need for puttying after drying under fine finish.

Dry building mixes with gypsum binder "Gipswell"

The compositions of this brand are a cheap analogue of "Rotband". Several varieties of such plasters are supplied to the market today. The most popular among the consumer is the Gipswell Osnovit mixture. Such plaster also comes in several series. For example, the mixture "Gipswell Found T25" can be applied to the walls with a layer of up to 8 cm. Also, this plaster is plastic.

In addition to the gypsum itself, the composition of "Gipswell Osnovit T25" includes additives that increase the "pot life" of the solution and plasticity. Like "Rotband", this plaster gives a very smooth surface and does not need additional puttying.

Consumer opinion about Gipswell

Good feedback about this plaster on the Web are available in the first place, due to the ease of application. The compositions of this brand, as noted by consumers, give a very high-quality finishing layer and at the same time are inexpensive. Low consumption is also considered an advantage of Gipswell building gypsum mixtures.

If the plaster on the surface needs to be applied in a thick layer, many consumers are advised to purchase this particular brand of T25. The finished finish in this case is guaranteed not to crack. Also, judging by the feedback from consumers, "Gipswell Found T 25" practically does not shrink. The advantages of this tool, many masters include the fact that the solution prepared with its use is able not to dry out for 1.5 hours.

Plaster "Bergauf": composition, description

The composition of gypsum-based mixtures from this manufacturer may include, in addition to the binder itself, the following components:

quartz sand;

mineral supplements;

plasticizers.

The solution prepared from the Bergauf mixture hardens in about an hour. Additives make it plastic and easy to apply. Also, mixtures from this manufacturer have excellent adhesive properties.

Reviews of Bergauf blends

The main advantage of plasters of this brand, consumers consider their low cost. The price of dry gypsum mixtures "Bergauf" with their high quality often lower than for some similar formulations, even from domestic manufacturers.

Despite the fact that these plasters contain sand, which is noticeable, judging by consumer reviews, even with the naked eye, they give a finishing layer that is quite even and smooth.

Plaster "Prospectors"

The mixture of this brand is great for finishing all kinds of surfaces. The same quality layer when using them is obtained both on brick and on foam concrete. A special light component is added to the composition of the Starateli plaster, which can significantly reduce its consumption. Also, mixtures of this brand contain mineral components that provide rapid hardening.

It is believed that the Prospectors plaster is just great for applying on surfaces like under ceramic tiles, and just for wallpaper or painting. It is possible to apply dry mixes on a gypsum basis of this brand on the walls with a layer of up to 5 cm. The “life” of a solution prepared using the composition of this brand is 45 minutes.

What consumers think about Starateli plaster

Consumers consider the main advantage of the mixture of this brand to be a very low cost with good quality. Also, the advantages of plaster "Prospectors" masters include:

smoothness of the finished surface;

ease of application;

optimal time setting.

The craftsmen consider some of the drawbacks of this brand to be that large grains of sand sometimes come across in its composition. Therefore, when working with Prospectors plaster, you should be a little more careful. Sand grains can leave grooves on the surface. If they are not sealed immediately, the wall may subsequently have to be puttied.

Gypsum mixture "Eunice Teplon"

Plasters of this brand contain perlite, which reduces their setting time. Distinctive feature means of "Eunice Teplon" are light weight and maximum strength of the finished layer. Also, the plaster of this brand is able to additionally protect the premises in the house from the street cold.

The duration of the "life" solutions "Eunice" is approximately 50 minutes. You can apply them on the walls with a layer of up to 5 cm.

Consumer opinion

The main advantage of Eunice plasters is ease of application. Many consumers, judging by the reviews available on the Web, consider dry gypsum mixes of this brand to be just perfect for beginners. The Eunice Teplon solution is applied to the walls very easily. In addition, the finished finishing layer when using it does not require additional puttying.

Some disadvantage of Eunice mixtures, consumers consider the difficulty in preparing the solution. It is necessary to knead this plaster for a long time and carefully until all lumps are removed.

Instructions for use

For the most part, gypsum plasters are thus plastic. That is, working with them is quite easy. But of course, in order to get a beautiful, durable finished finishing layer, when working with such compositions, all the required technologies should be observed.

Before starting plastering work, the surface must be cleaned of dirt, dust off it and primed in two layers. Next, you can start preparing the solution. At the same time, the amount of dry gypsum plaster mixture should be taken such that the finished composition could be fully used while it retains its "viability".
