Preparing walls for decorative plaster. Preparing the surface for decorative plaster: step-by-step process for preparing walls, tools for work Putty for decorative plaster

You can do the steps before applying decorative plaster yourself. It is important to remove large defects, clean old paint, remnants of wallpaper, and whitewash. The article describes the work plan and the secrets of preparing various surfaces.

How to do it yourself, secrets of preparing different surfaces for plaster

Even high-quality finishing material will crumble if you lay it on unprepared walls.

The steps before applying plaster are not supernatural; they can be done with your own hands.

It is important to remove large defects, clean old paint and remnants of wallpaper, whitewash. The plaster itself will correctly and accurately hide minor irregularities on the surface being treated.

Is wall preparation necessary?

Preparation is necessary if this is not the first renovation, that is, there is already old wallpaper, paint, and whitewash on the walls. You will also need to remove defects if the walls, even if the room is being put into operation for the first time, have unevenness.

Decorative plaster is applied both indoors and outdoors. Also on sale are various types: textured, structural, Venetian, latex and others.

Since plaster is intended for various conditions use, and also gives a different effect, its composition changes. Consequently, the preparation of concrete, plasterboard, brick, wooden walls will be different.

Features of the work

There is no need to be overzealous in preparation, because decorative plaster is applied in a thick layer and hides minor defects. A perfectly flat surface is not needed; it is important to remove all cracks, debris, and serious convex or concave areas at the initial stage.

If you leave noticeable defects, they will appear through the decor. In this case, you will need to apply a larger layer of decorative plaster, which is significantly more expensive than it would cost to initially level the walls.

How to properly prepare an old uneven wall

Finishing with decorative plaster - final chord repair. Work is carried out after installation of plumbing, doors, removal construction waste. Installation is carried out in clean and tidy conditions; construction debris and dust that may appear during unfinished repairs will settle on the decor and ruin it appearance.

Work on preparing the walls begins a month before applying decorative plaster. The walls must stand for at least 4 weeks to ensure the quality of the work performed. Plan for preparing an old uneven wall:

removing layers of putty, paint and wallpaper (you can manually or use a construction fan);
removing oil stains (they are removed with a soap solution or solvent);
work with cracks (expansion grinding machine, filling with building composition);
primer treatment (if the walls are normal, then you can use a regular one, if you are prone to cracks, it will have a restorative effect);
treatment with an antifungal compound (if the walls are outdoors, that is, they are susceptible climatic conditions, indoors with high humidity).

The operating principle and sequence of actions depend on the type of surface.

Preparation for decorative plaster of various surfaces

Different surfaces require the use of different tools. So, for processing:

For cinder blocks, chisels and brushes with steel bristles are suitable;
concrete is used sandblasting or the same as for cinder blocks;
wooden shingles with a strip width of up to 30 mm and a thickness of up to 5 mm are suitable;
brick ones first use the technology of creating beads on the seams, and then scraping with a brush with steel bristles.

Leveling the surface occurs quickly as the material sets. In this case, the surface must be wetted.

When can you plaster?

Most masters advise applying decorative plaster no earlier than a month after alignment. This is due to the fact that during this period it will be possible to examine defects if they appear.

But, in fact, if the worker is confident in the quality of the completed task, the plaster can be used immediately. You need to wait until the humidity is optimal - walls that are damp from work tend to crumble.

The application technology is no different from a plasterboard surface. Venetian is applied in several layers, and it is important to wait until each layer dries. Textured is heavier, so when applied to drywall, consider whether the surface can withstand it. Structural and mineral are not so demanding on the surface, but the load also needs to be taken into account.

Recommendations will allow you to get an ideal and long-term result. Adviсe:

if drywall is used, it must be moisture resistant;
the surface, if there is a risk of liquid ingress, is treated with a moisture-resistant primer;
During repairs, cleanliness and temperature regime, otherwise the appearance will deteriorate.

You can prepare walls for decorative plaster with your own hands. It won't take long. If you approach the issue responsibly, the decor on plasterboard or a putty wall will retain its appearance for decades.

Decorative plaster is a truly unique finishing material that allows you to create interiors that are unique in their beauty.

It is no wonder that the popularity of such compositions is growing year after year. However, decorative mixtures can fully reveal all their aesthetic advantages only if the load-bearing base is properly prepared, so the preparation of walls for decorative plaster must be done with special care.

Types and features of material

Decorative plaster must have aesthetic qualities and be sufficiently durable

Decorative plaster coatings in their composition, technical specifications and the method of application are radically different from conventional plaster solutions.

The main purpose of base or finishing compositions is to level load-bearing surfaces, eliminate various technical defects, and prepare them for further finishing.

In contrast, decorative plaster is designed for use in interiors as a final wall covering. Due to operational and technical features of this material Preparing walls for decorative plaster has its own nuances.

First of all, we should take a closer look at this coating from the technical side: its characteristics, pros and cons, varieties, application, etc.

Varieties

All decorative plaster mixtures are divided into two main categories:

Natural ingredients.
Polymer.

The first group includes mixtures prepared on the basis of natural ingredients. These are the following compositions:

mineral. Their basis consists of mineral fillers large fraction, often painted in different colors. The connecting link in such mixtures is cement. The treated surface has a grainy texture that shimmers in different shades;
calcareous. This solution is based on slaked lime with the addition of fine sand and cement;
plaster. Gypsum solutions are easy to use and flexible. They have a number of operational restrictions - they can only be applied to interior walls rooms with natural humidity levels.

Special texture rollers will help create an original surface

Polymer compositions can be silicone or acrylic. Based on the technology for creating an aesthetic effect, mixtures are divided into textured and textured.

Texture mixtures have a three-dimensional pattern, applied using a trowel, texture roller, or stencils.

In textured mixtures external effect achieved thanks to color scheme simulating expensive coatings- first of all, polished marble and granite slabs.

Advantages and Disadvantages

The wide popularity of such finishing mixtures is explained by a whole set of positive qualities, which sets them apart from most other wall coverings. Among the main advantages are:

Only a professional can create a particularly complex texture

Exclusive plaster coatings are not without some disadvantages. Of course, they are not so critical, otherwise these mixtures would not be so in demand among buyers. There are only two main disadvantages that may influence the choice:

high cost. The price of the material is quite comparable to the high aesthetic effect that can be achieved with its help. Usually it is several times higher than the cost of conventional base or finishing compositions;
difficult application. Applying the mixture to the wall has a number of features, sometimes very difficult from a technical point of view.

Therefore, before choosing this material, you need to soberly assess your skills in the finishing craft. Otherwise, you can waste expensive plaster mixture, or, as an option, spend extra money on the services of professional finishers.

If, after all, the choice is made in favor of this expensive exclusive coating, you should consider in more detail how to prepare the walls for decorative plaster so that it can last as long as possible.

Preparation stages

Clean the wall from debris and dust and cover it with primer.

The entire procedure for preparing walls for decorative plaster can be divided into several stages.

Surface cleaning.
Leveling plastering.
Primer.
Putty.

Proper surface preparation implies stage-by-stage and high-quality completion of all the listed works. At the same time, walls can be prepared in a special way for each type of plaster.

Applying a decorative composition to the walls in a new building always requires preliminary leveling of the base and (or) finishing plaster. The fact is that new walls, whether they are made of brick, cast concrete or made of wood, always have some flaws.

It might just be small chips and sinks, seams too deep. And there may be more serious defects in the form of crooked walls. Moreover, at first glance, the curvature of the walls may not be noticeable. But finishing in some cases, it can emphasize this drawback, making it so noticeable that it will cancel out the entire effect of expensive repairs.

Fix wall defects using decorative mixtures will not work because they are designed to be applied in a thin layer. No more than 1.5 - 2 mm. And this is clearly not enough to correct more or less significant defects in the load-bearing foundation.

Therefore, all walls in a new home should be carefully inspected using a construction or laser level. In case of significant deviation in the vertical or horizontal direction, a leveling plaster layer should be applied.

Alternatively, preparing walls for decorative plaster may involve covering them plasterboard sheets- the so-called “dry plaster” technology. This method of leveling walls is simpler than “wet technology” and requires less effort and time. To learn how to apply the leveling mixture, watch this video:

However, it should be taken into account that gypsum board sheets together with the frame eat up a significant amount of room space - at least 50 mm for each wall.

Wall cleaning

Thorough cleaning should be done before application. plaster mixture any type on previously treated walls. During the work, you need to clean the surface from old wallpaper, paint and varnish compounds, putty, right down to the layer of leveling plaster. For cleaning you can use any suitable tools- spatulas, trowels, picks, grinders.

To remove wallpaper faster, moisten it with soapy water or special liquid for removing wallpaper. You can buy it in the same stores that sell wallpaper and wallpaper glue. Regular paper wallpaper simply moisten with the composition using a roller or brush.

Soapy water treatment will help remove old wallpaper

Waterproof vinyl sheets should first be perforated with a needle roller, a “wallpaper tiger” or an ordinary knife so that the liquid has access to back side wallpaper and wall surfaces.

You can try to remove the paint with a spatula, starting from the bubbling and peeling fragments. If it holds too tightly, you should move on to more radical measures - resort to using a grinder or hammer drill. Lime whitewash can simply be washed off with a damp cloth, passing it over the entire surface of the wall several times.

Removing the putty can take quite a long time, since it is applied in a thin layer, but at the same time it has good adhesion to the underlying base. To facilitate its removal, it is recommended to prepare a special composition from a mixture of starch and water in a ratio of 1 to 20 or 1 to 15 in especially difficult cases. For more information on cleaning the base, watch this video:

The putty walls are moistened with this solution and left to soak for 15 - 20 minutes. After this, simply scrape off the layer of putty using a spatula.

Primer

The soil will improve the adhesion of the wall with the mixture

The primer allows you to create a strong adhesion between different finishing layers.

Primer compositions increase adhesion, significantly extending the service life of the coating, so preparing walls for decorative plaster necessarily includes treating their surface with primer mixtures.

For greater effectiveness, primers are applied in at least two layers. Each subsequent layer should be applied only after completely dry previous.

In the modern market of finishing materials there is huge amount primer compositions that differ in their purpose and scope. If the walls are in a room with increased level humidity, they must be treated with antiseptic primers. These protect surfaces from the formation of mold and fungal infections.

A special primer for decorative plaster is also available for sale. It is used mainly under textured “ Venetian plaster", applied in a thin layer of less than 1 mm. The wall is first treated with a regular primer, after which it dries, a tinted acrylic primer is applied to the wall.

In some cases, instead of a special primer composition, a regular one is used as the underlying layer under the “Venetian” acrylic paint the desired shade. It allows you to add depth of color to Venetian plaster, which enhances the “marble” effect and gives the wall a more natural shade.

Putty

Keep in mind that texture compositions are applied in a thicker layer than textured ones.

Preliminary puttying of surfaces is carried out before applying textured and colored compounds. If you are going to treat the wall surface with textured plaster, then the puttying process can be omitted.

The fact is that textured compositions - “fur coat”, “rain”, “Leonardo” - are applied in a thicker layer than textured ones. After application, they are further processed with figured rollers or rubber stamps to give them a textured relief. Therefore, their layer can reach up to 3 - 5 mm, which is quite enough to mask minor wall imperfections.

If you plan to treat the walls with thin-layer “Venetian” mortars, it is simply necessary to improve their surface with putty. To do this, you need to carefully examine the wall for cracks and crevices, which must be carefully sealed. Over time, any, even minor cracks tend to expand and increase, so defects left unattended can soon transfer to the decorative layer.

To seal cracks, they must be carefully expanded and cleared using a knife or thin spatula. After this, the gap is cleaned of dust and covered with putty along its entire length. Also, before applying the “Venetian”, the entire surface of the walls is puttied to give it a perfectly smooth appearance. After finishing the work and the putty layer has completely dried, the entire surface of the wall is primed again. For more information on how to prepare walls for the bark beetle, watch this video:

If the apartment owner has some experience in finishing work, he can independently prepare the walls for finishing with exclusive and expensive plaster mixtures. But if you have the slightest doubt about your competence, then it is best to entrust the work of preparing the surface and applying an expensive decorative coating to professional finishers.

Preparing walls for decorative plaster is an important point, because the final result will depend on the quality of preparation of the base. Today we will tell you how to prepare walls for decorative plaster and at the same time provide for everything. Also in the video in this article and photos you can see individual moments of the work and this will help to carry out the work correctly.

Preparing the wall for plastering is done in a certain order. Everything is time-tested. It must be remembered that applying plaster is the stage that completes finishing work. Plastering begins after all windows and doors are in place, full installation flooring(see Floor tiling with ceramic tiles - correct tiling).

Surface preparation is carried out in the following sequence:

First, the surface to be finished must be cleaned of the old layer of putty and paint., remove the remains of the previous wallpaper;
Next, the wall surface is treated with a special primer mixture., which performs a restorative and strengthening function;
If the humidity in the room is very high, then along with priming, you should additionally treat the walls with a product that has an antifungal effect;
If there are cracks on the walls, then they are embroidered and filled with a special composition for repair. Very large cracks are filled with a repair compound in several approaches;
Only after the walls have been completely primed should a putty layer be applied to them., which completes the stage of their leveling and is the basis for finishing the surface with a decorative plaster coating.

Attention: If in the future you plan to apply a thick layer of plaster coating with a clearly formed structure, then puttying the walls in this case is not necessary.

If decorative coating will be applied in a thin layer, then preparation should include all stages without exception. Otherwise, it will not be possible to hide all the errors in the base under the decorative layer. This will also lead to increased consumption finishing material.

When all the putty work is completed, you can begin sanding the surfaces of the walls (see How to sand walls after putty and how to do it correctly), using fine sandpaper.

Priming the wall surface

Preparing walls for decorative plaster is done using a primer. It significantly enhances the adhesion of surfaces and ensures the durability of the coating. Here everything is done with your own hands and therefore the price of the work will be reduced to the cost of the material.

Warning: This step is very great value, because a good primer mixture can preserve the repair for a long period of time. In this case, you don’t have to worry that the plaster will crumble.

The primer for plastering is an opaque liquid that does not have a characteristic odor; priming is the work of applying and distributing the primer over the surface of the treated area. Once dry, it becomes like a film, which strengthens the surface and improves the adhesion of the plaster.
The primer penetrates deep into the wall, improving its adhesive properties and preventing metal corrosion. The waterproof film prevents the penetration of moisture, provides protection against bacteria, preventing the formation of mold and rot on the drywall surface. Under it you can hide small stains and traces of drips. Applying the primer mixture in several layers enhances the properties of the composition.
It is advisable to buy a mixture of high quality and deep penetration, this will reduce the cost of finishing materials. It’s good if the brand of primer matches the brand of the plaster mixture. Each manufacturer produces its products in entire lines, where all components fit together perfectly.

Which soil to choose

Preparing walls for plastering, the video will show you the entire progress of the work. But the soil must be chosen correctly. According to the coating structure. On shelves today construction stores you can meet huge assortment primer mixtures. In order to do right choice, you need to know which primer is suitable for certain surfaces.

Alkyd primer is perfectly applied to untreated wood, leveling its structure and creating a smooth surface for plastering. The advantages of this mixture include quick drying. You can use a polystyrene primer; it can also be applied to plastered surfaces. But it should be noted that it contains substances that are harmful to health.
For metal surfaces A primer is used, which is specially produced based on the type of metal. Usually these are mixtures with zinc additives. It is possible to use an alkyd primer mixture with zinc additions, which provides anti-corrosion protection. The use of glyptalin mixture is difficult because it has a long drying period.
The use of perchlorovinyl primer mixture is recommended for concrete and brick surfaces. It dries quickly, but has a pungent odor. Therefore, it is better to carry out work with open windows.
Acrylic and emulsion primers can be applied to any surface. They are practically odorless, and their drying period is 5 hours. Acrylic primer It can even be applied to an old layer of plaster; thanks to its composition, it ensures its strengthening. Also, the acrylic mixture is perfect for drywall surfaces.

Method of applying primer mixture

The technology for preparing walls for plastering includes high-quality application of primer. Having bought everything necessary materials, you can begin priming the walls before plastering them. It is worth noting that primers are sold in three different states: dry, concentrated and diluted.

Diluted mixtures can be used immediately. Before starting work, the diluted primer is thoroughly mixed so that all sediment rises from the bottom and distributed throughout the entire volume of the mixture.
Dry and concentrated mixtures are first diluted according to the proportions recommended in the instructions.
Before starting priming work, you need to clean the surface of the walls. Grease and oil stains should be removed and all dust and dirt should be wiped away.
To prevent the mixture from getting on the painted areas, they must be sealed with a special film or tape. The primer leaves glossy spots on the paint.
On plasterboard surfaces, it is necessary to seal the joints using a special mesh. Work should only be done with gloves, because these mixtures have a detrimental effect on the skin and are not easily washed off.
Now let's look at the priming technique itself.

Preparation for plastering walls with a primer includes the presence of a certain tool and to complete the work you will need the following equipment: a brush for areas with difficult access, rollers with long and short handles, a container for primer and the primer mixture itself.

First you need to apply the mixture to easily accessible areas of the wall with a roller on a long handle. Next, use a smaller roller to evenly distribute the primer, moving it up, down and in both directions.
Next you can go to hard to reach places, corners and joints. To do this you need to use a construction brush. Once you have finished applying the primer, you should let it dry. Drying time is indicated in the instructions for the solution.

Attention: Preparing walls for plastering, the video will show the rules for carrying out the work, but if the surface is large, then it is better to purchase a spray bottle for the work, this will significantly speed up the work and you will be able to make a uniform coating.
Don't limit yourself to just one coat of primer. To enhance its properties, it is necessary to re-apply the mixture. You need to carefully inspect the surface of the walls so as not to miss even small area. As soon as the second layer of primer mixture has dried, you can begin plastering the walls.
When preparing walls for plastering, it is necessary to take into account a number of important points, affecting the quality of work performed:
All applied putty layers must be thoroughly dried. Drying time should not be less than 2 days;
To prevent cracks from forming, you can use a special self-adhesive mesh. In another way it is called “serpyanka”;
after the putty layer has dried, it is recommended to prime all wall surfaces with an acrylic primer mixture, due to its penetration far into the wall, ensuring good interaction with the decorative coating;
You can increase the strength of the primer and protect it from separation into layers by using a special impregnation. It should be taken into account that the selected putty mixture must have good absorbent properties. Oil and alabaster bases are not allowed.

When applying a primer mixture for decorative plastering, you should use the advice of experts:
The primer layer is applied to the wall surface approximately 2 centimeters thick., its smaller thickness will not allow obtaining a decorative coating of uniform composition and high quality;
When rubbing the primer layer, it is imperative to take measures to compact it;
After completing the priming work, it is necessary to periodically moisten the treated surface.. This should continue for a week. Moisten with a sponge moistened with water.
After carrying out all the above procedures, decorative plaster can be applied to the treated surface.

Decorative coating testing
Having completed the preparatory work, be sure to apply a test layer of decorative plaster. This is necessary to check the readiness of the wall surface.
To do this, select a small section of the wall located near the corner of the room and apply a layer of plaster. This will give you the opportunity to see what quality the decorative coating will be, its structure and color scheme.
Particular care must be taken to ensure that the transitions between smooth and textured coating surfaces are sufficiently smooth.
Also, if you use stamps, then immediately check the embossing, it must be of high quality.

You now know how to prepare a wall for plaster, and the video for preparing walls for decorative plaster and the above instructions will not allow you to make mistakes when carrying out the work.

IN lately decorative plaster is becoming popular indoors. It would seem, what could be simpler? But, in this case, it is better to do everything as it should, since the material is not cheap and applying it to an unprepared surface can only ruin everything. All the beauty of this material can be fully revealed only on absolutely correctly prepared walls. When preparing walls, be sure to follow all stages of work accurately and completely.

Work should begin with the most thorough cleaning of the walls. To do this, you should remove all old coatings from them: wallpaper, paint and everything unnecessary, including old plaster, preferably down to the base. Next, you need to remove dust from the walls. This can be done with an ordinary industrial vacuum cleaner. A household one is not suitable for this work, since it does not have enough power for this. Please note that preparing walls for decorative plaster is a responsible process; you should very carefully remove not only paint and wallpaper, but also greasy spots, you should not leave them, as later they can spoil the finished look and you will have to redo all the work. Stains are easily removed with a solvent and then with a soap solution. This process does not take much time. Removing the same old plaster will ensure better adhesion of all future layers of coatings to the wall. If this stage is omitted, then in the future the plaster may simply begin to fall off. All stages of work should be carried out especially carefully if Venetian plaster is intended to be used, since uneven walls with defects it will lose all its attractiveness.

Elimination of defects and cracks

If there are cracks on the cleaned wall, they must be eliminated, since decorative plaster will not hide them, but will only make them more contrasting. This means that in order to prepare the walls for decorative plaster according to all the rules, the cracks should be repaired. To do this, using a special grinder existing cracks are expanded and cleaned. Then, they are filled with a special repair compound, when choosing which it is better not to focus on cheap analogues, it is better to choose a professional mixture and a little more expensive than to take a cheaper and low-quality one. If the gap is large and deep, then the composition will have to be applied in two passes. If indoors most of the time there will be high humidity, then the wall must be treated by special means from fungus.

But, if the room is dry, then this stage of work can be safely skipped.

Preparing walls for decorative plaster must necessarily include the stage of leveling with putty. Especially if the plaster is planned to be applied in a very thin layer. If it is planned to be applied in a sufficiently thick layer, then the wall does not need to be puttied. But it is necessary to prime the wall surface in any case. Because the primer allows you to prepare the surface for better adhesion of the putty to the wall. The primer is chosen depending on what material the wall is made of. As a rule, an alkyd-based primer is applied to the wood; it also dries quite quickly. For metal walls, there are specialized mixtures with the addition of zinc, which, among other things, helps protect the surface from corrosion.

It is more convenient to start leveling work from the corners of the room. It is better to apply the putty composition with a special “wide” spatula. And there is a little secret: to prevent the putty from cracking, it is better to apply it to a special self-adhesive construction mesh. The putty layer must be dried after application. After the putty dries, “each layer dries for at least a day,” the surface should be primed and sanded.

Sanding should best be done by hand using a special fine-grained sandpaper. sandpaper.

After sanding, the surface should be primed again. Ideally, use a special primer on acrylic base with a deep penetration effect so that the adhesion of all layers is the best. From the above it follows that preparing walls for decorative plaster with putty excludes the use of putty for leveling, which prevents the absorption of “oil-glue or alabaster”. Moreover, the thickness of the primer layer should be at least two centimeters. This is necessary so that the layer of decorative plaster lies evenly and uniformly. After applying the primer, be sure to first compact it by rubbing it with pressure, and then moisten it several times a day. Moisturizing is necessary for at least seven days. In this case, the surface will be ready for applying any plaster, both smooth and embossed.

We must remember that the better the wall surface is leveled, the smaller the layer of decorative plaster can be applied to the wall. Since decorative plaster is not cheap, this fact should not be underestimated when performing work.

Before starting the main work, you should apply a small area of plaster to the wall near one of the corners of the room. This will allow you to evaluate the texture of the future coating and its color.

If something doesn’t suit you, you don’t have to redo all the work from the beginning, you only have to redo this small area. If the preparation of walls for decorative plaster was carried out correctly at all stages, then this, final stage work will be quite easy. But there’s still no need to rush. First of all, you can watch video tutorials on various resources on how to apply it to obtain a variety of unusual effects.

You can apply plaster alternating smooth and textured different colors. To perform such work, great care and great attention is required so as not to spoil the finished effect. When applying layers of plaster in this way, special masking tape is used to protect the applied layer. This secret will help you avoid trouble if small mistakes are made. Masking tape is applied to the areas where textured plaster is to be applied. Smooth plaster is applied to all areas that remain free. Then the tape is removed and the areas with smooth plaster are glued. Texture plaster is applied. Then the tape is removed. This tape does not damage the already applied surface, which is why it is called painting tape and is used by professional craftsmen.

Working with decorative plaster allows you to widely use your imagination by combining it with textures. The main thing for working with it is to correctly prepare the walls for decorative plaster, absolutely smooth surface no dust, cracks or holes. This allows you to avoid distortions in shades and unevenness in applied stripes and lines. And also decorative plaster, applied according to the rules, will last for a very long time, which means it will serve its owner for a very long time. Naturally, after a dozen or two years it will no longer look as fresh as in the first years, but its service life is very long, it opens up very wide possibilities for imagination and this fully justifies its high cost.

It is for these reasons that one should not neglect the precise implementation of all stages of work to prepare walls for applying decorative plaster. You should approach your work very carefully and responsibly and it is better to double-check the result at each stage. Since defects can “come out” already under the finished finish and all the work will have to start from the very beginning, which is fraught not only with high monetary costs, but also with a large expenditure of time and effort.

Excellent result, which will delight you for years, can only be obtained with an ideal or almost ideal surface, since a thin layer of expensive decorative plaster cannot hide defects made during preparatory work. This means that you should not rush, skip or ignore the required stages of work. If you feel that you cannot do the work yourself, then it is better to turn to trusted professionals for this.

You need to prepare to create a masterpiece. No matter how high-quality the finishing material is, all its advantages can only be revealed on properly prepared walls. Preparing walls for decorative plaster is not much different from preparing for applying any other type of finish. The surface must be cleaned of wallpaper residues, old paint, whitewashing, without trying to achieve ideal smoothness. Most compositions perfectly hide minor defects; your task is to eliminate large ones.

Preparation stages

Decorative plaster is the last stage of construction or renovation. Windows and doors must be installed, work on the ceiling and floor must be completed, the room must be cleared of construction debris, dust and dirt.
The surface is prepared as for painting. It must be leveled, scratches, chips, potholes, cracks must be repaired and covered acrylic primer, with the exception of matte ATF.
If the surface is not dense enough, it should be treated with strengthening or restorative primer. The primer strengthens the wall, serves as additional protection against moisture and improves the adhesion of the coating to the surface. Room walls with high humidity subject to treatment with antifungal agents.
The cracks should be “opened” and filled with a special putty.
The primed surfaces are putty; each layer of putty must dry for 24 hours.
To avoid cracking, it is recommended to use serpyanka or non-woven wallpaper. The joints must be thoroughly puttied and sanded after drying.
Each layer of putty is covered with deep penetration acrylic primer.
The use of finishing putty materials that prevent absorption, in particular, materials based on alabaster and oil-based adhesive, is not allowed.
Fine abrasive sandpaper is used to sand the surface.
Before painting begins, preliminary painting should be done. This procedure is necessary in order to preliminarily evaluate the invoice finished coating and its shade.

The above sequence of actions when preparing walls for decorative plaster is the most general. In each specific case, preparation may vary depending on the properties of the material, the characteristics of the room and the desired result. The surface requirements are much lower when using structural compositions.

Structural plasters are a universal finishing material that can be used for any base surfaces both outside and inside the building. With their help, even the most ordinary house can become a masterpiece. Structural plaster is plastic and easy to apply. Among its undoubted advantages are almost limitless possibilities for experiments with surface texture and color.

Before deciding on a style revolution and choosing a method for applying decorative plaster, it is better to consult in detail with a finishing specialist. For all its promising efficiency, decorative compositions- not the best cheap material and only a thoughtful approach will help you avoid extra costs. We invite you to familiarize yourself with several dozen secrets for using this finishing material in the video below.
