Primer ceiling under painting. Grinding ceiling: Step by step instructions How to primer concrete ceiling

A modern approach to the repair process involves the use of a number of materials. This also includes primer for the ceiling. Disputes are constantly being conducted around this fluid: some masters do not see expediency in its use, others, on the contrary, consider the primer with a mandatory component of repair. Avoid doubt help the knowledge of all subtleties of use.

Purpose

For what a primer needs - this question is asked not only newcomers of the building process, but also very experienced masters. Purpose of fluid in the following:

  1. Hardening of the concrete surface. Liquid consistency allows the means to be easily absorbed. The water contained in it under the influence of positive temperatures is gradually evaporated, leaving solid particles in concrete. The latter and are responsible for improving the strength of the ceiling surface.
  2. Increased adhesion. The primer creates a film on the ceiling, which improves the clutch of the plate and finishing material.

Some varieties of funds have bactericidal properties. After their application, the surface of the ceiling becomes resistant to the appearance of mold, the development of the argument of the fungus. This quality is invaluable for premises, where children are located for a long time, as well as people with diseases of the respiratory system.

Often the question arises, whether it is necessary to primer the ceiling before painting. The main purpose of the means is to prevent moisture absorption to the surface of the ceiling. The missed phase of treatment with liquid when painting will manifest itself in the fact that more layers will be required to evenly close the entire surface. Even applying a putty, it is impossible to exclude the likelihood that the paint will start to crumble after a while.

What are the primer mixtures

Materials for processing ceiling plates have a different composition depending on the type of base surface. It is also important to take into account the type of room. For example, acrylic, alkyd primer, as well as a means having a mineral foundation, is the best choice for rooms in the house, apartment, office.

Acrylic primer can have a different composition, which allows it to divide it into several types.

Impregnating

Such a means needed when working with a bulk basis. The loose structure of plastering mixtures, putty allows the facility containing latex, penetrate to a depth of up to 10 cm. As a result - a monolithic basis that will last long enough.

Strengthening

It does not particularly penetrate the base. Its purpose is to associate those parts of the base that weakly hold. Such a composition is used, for example, if the ceiling is covered with a stucco with a small fraction. Also, such a primer is needed if you need to strengthen minor cracks. Both of these types of primer are shown to work with surfaces that previously underwent packed.

Adhesionic

Due to the presence of acrylic in the composition creates a film based on the film. In the future, this allows you to significantly save on finishing materials for subsequent work. This type of primer is easily combined with almost any paint. Even putty apply much easier.

How much does any variety of primer with acrylic? On average, from 6 to 12 hours. Specific time depends on how the foundation was.

Selection depending on the basis

  1. The primer for the ceiling under painting having a water base is suitable for water-free coatings and paints. This tool is recommended to use when it is necessary to prepare a plasterboard, wooden, concrete or cement base for plating wallpaper. Such a primer is dry enough. At this time, even minor temperature differences should be avoided.
  2. On the bases made of fiberglass, the applying of primer on an alkyd basis is recommended. The finishing layer is obtained very durable.
  3. Ceilings made of brick, concrete, ceramzite concrete and gas silicate blocks, as well as plaster trimmed, it is better to cover a mineral-based primer.

Special cases

Many owners of old housing are wondering how to primer the ceiling (and whether it is worth doing this), if he is closed or it is planned to put a putty.

Most often, the question of the need to progress the base, which was previously packed, occurs when a homeowner decides to paint the ceiling. Before starting work, it should be determined that it was the basis for the applied composition - chalk or lime:

  1. Whistling with lime, if it was not covered with cracks and not fall off, just wipe with a damp cloth. After the surface is completely dry, you can safely move to priming and staining (even water-level paint).
  2. For surfaces with a chalk coating, it is necessary to carefully estimate the condition of the surface and determine how many layers were applied. In the absence of cracking and a thick layer, the ceiling is covered with a special primer in whitewash.

How to apply primer to the ceiling, previously blued? Technology includes preliminary surface cleaning from dust and other contaminants. After that, it is recommended to apply the first, trial, layer. Then you should wait from two hours before the day - so much driving the primer composition depending on its base. It is impossible to allow drafts - the risk of discontinuation of the base coating increases.

After the first layer is completely pros, and on the surface there are no signs of detachment or swelling, the second is applied. How much should there be layers? Experts argue that at least three. And before applying new, the recommended time should be shown until the previous one dries. If even minor durability violations were identified, it is recommended to return to the stage earlier and completely remove the old coating.

Protecting before Shptelsivania

How to properly grind the ceiling, if a putty will be applied to it? Is there a need for this? The priming process in this case allows you to solve two tasks:

  1. Disinfection. After the tool is applied to the ceiling slab, its surface gets reliable antifungal protection.
  2. Increased adhesion. Spike - enough heavy material. Therefore, in the absence of a primer coating, it can start peeling over time. Technology suggests layer-by-country application. That is, after the layer of putty is applied and sandwich, it is covered with a primer.

The tool cannot be applied at the time when the base dries. The type of primer used and the ceiling plate material determine how long it will take it.

If the ceilings are stretched

Consider whether the ceiling should be primed to which the design with PVC film will be installed. Stretch ceiling - the best solution for apartments in new buildings. Over time, the house seats, after which the surface of the plates is covered with cracks. To minimize repair costs, homeowners and resort to the use of tensioning design.

PVC film reliably hides all flaws. After installing it, you can forget about the repair for a long time. However, this does not mean that the surface under the stretch design should not be processed. Primer - the minimum that can be limited to.

As you know, the stretch ceiling often protects the apartment from the moisture coming from the top floor. It is easy to remove it. But while the unprocessed surface of the plate dries, microbes are multiplied in it, fungi can develop.

Primer provides protective properties. That is why the ceiling under the stretch design must be processed.

Important moment

When choosing a primer, it should take into account not only the period of time as it dries. First of all, it is necessary to determine the amount of means that will be required for surface treatment.

To find out how much priming is needed, determine how many square meters to be treated. The resulting digit is multiplied by the flow rate according to the instructions. Also, such nuances should be taken into account:

  • type of primer;
  • assignment of funds;
  • base material.

Given the listed moments, it is not difficult to determine how much the means you need to evenly and fully cover the ceiling.

It is important to remember that another important point is affected by the calculations - the thickness of the layer. This indicator depends on how porous is the ceiling base material. The higher the porosity, the more layers may be required. In order to avoid mistakes, it is better to attract specialists to calculations.

If you started repairs in the apartment, then in any case it will have to start it from the ceiling. And the first question faced by the manons, how to primer the ceiling and what. The atmosphere depends on the quality of the execution and appearance of the ceiling, the atmosphere in the room and comfort depends on the choice of materials and the solution.

What kind of primer is better for the ceiling?

Acrylic primer is capable of overhaul to dry in just 10 hours.

Choosing a primer for the ceiling in your home, it should be understood that this solution is necessary for better and even applying paints on it. The masters of the specialists are adhered to the same opinion. In addition, the primer provides a stronger and reliable grip of paint with the surface, due to which the ceiling coating will be held for many years. It's all about the special components of the primer solution, which, after application to the surface, penetrate into the pores, and on the surface create a thin film, which just provides a solid paint connection with the primer.

Experts believe that even if the surface of the ceiling is both in perfect condition, it is still necessary to produce primer.

The primer for the ceiling is selected, based on the surface features on which it is planned to apply it, as well as focusing on the technical and qualitative characteristics of the mixture:

  • for plastering and shpocking concrete surfaces, a primer is selected having a depth of penetration of up to 5 mm. The presence of antiseptics as part of the primer for concrete surfaces is necessary, so they help protect the surface from mold and the development of fungus. In this case, it is quite possible to use a universal mixture;
  • the construction market is rich in the proposal of various primers, so as not to suffer when choosing, stop your choice on the same manufacturer as paint, picking them in the depths of penetration. Such a choice of one hundred percent will provide a positive result. This is due to the fact that one manufacturer, as a rule, makes almost all the mixtures using one base. Read and what materials will be needed.

Primer ceiling before painting

Between the masters and beginners there are eternal disputes on the need to primer the ceiling before painting. Earlier, we already found out that the primer is needed before painting, the practice shows. Creating a thin film on the surface, the primer provides a stronger and reliable grip with paint. As a result, there is a highly painted ceiling, the repair of which can not be worried about a long time. The presence of primer is very important due to the content of elements in its composition, providing link properties:

  • the presence of primer provides an increase in the surface of the ceiling;
  • improves the clutch of the working surface with the finishing material, including with the water-level paint (in the case of using water-level paint, the primer is applied only penetrating);
  • due to the ceiling primer, paint consumption is significantly reduced.

Types of primer ceiling

  1. The primer on a whitewashing for ceilings is recommended to use deep penetration, it is considered in this case it will not be necessary to wash off the old paint. Although experienced masters claim that old paint should in any case need to be washed away, otherwise the primer will not be able to penetrate the lime 100%, and the grip will in this case be weak.
  2. Acrylic primer for the ceiling is used on concrete, brick and stone surfaces. Great for concrete ceilings, contributes to the leveling of the working surface, enhances adhesion or clutch, reduces paint consumption. The main property of this primer is a decrease in the absorption of the surface layers of the ceiling, for example, dry putty.
  3. If the difference is less than 3 mm, or the ceiling has a porous surface, the primer of deep penetration for the ceiling is used. After all, the main purpose of the primer is to enhance the ability of the surface to bind moisture. Such primer is ideal for surfaces performed by their drywall and foam-aerated concrete.
  4. Primer before putting the ceiling is simply necessary. What kind of soil to choose is solved, based on the material of the working surface. Since, for example, alkyd primer, used only for wooden surfaces, is not suitable for coating a metal or concrete.
  5. Any primer for the ceiling is perfect for the walls. There is no separation on the ceiling primer or wall. The principle of operation is one. About the advantages of LED backlighting with the Ceiling Device, read.

How to apply primer to the ceiling?

The ceiling primer technology is quite simple:

  1. The primer is poured into a special ribbed bath, in size equal to the roller width.
  2. The roller is used on a special long smooth stick so that you can get to the ceiling and capture a fairly large range in width.

    In this case, the stepladder will not need, you can safely engage in the primer, standing on the floor, and not jumping and moving the stepladder.

  3. The roller is cooled into the primer solution, the excess is removed by renting it on the ribbed surface of the bath. Next, the roller is designed the working surface of the ceiling in one direction. The coating must be homogeneous, without spaces.
  4. During drying, which is indicated on the packaging of primer, it is necessary to postpone work. After complete drying, the coating must be applied a second layer of primer, only the direction of the smears is already perpendicular to the first layer.
  5. If the primer is made under painting, then only a roller is used as a tool. Professionals recommend using a roller with a long soft natural pile. If you use a foam rubber, there will be bubbles, and there is little primer on the roller with a short pile.

Cost of primer for ceiling

Where to buy primer for the ceiling?

Beautiful, smooth, smooth ceiling - the dream of the hostess and the pride of the host of the house. Well, when it is possible to make such a ceiling due to the stretch or invite the team of professionals who can turn the concrete slab into an almost artistic product. If there are no such possibilities, the primer ceiling falls on the owner's shoulders at home. This means that you will need:

  • Clean the surface of the ceiling.
  • Protect it throughout the area.
  • Exactly and qualitatively apply the selected paint.

Note that the paint should correspond to the composition of the primer itself, and vice versa! So, it is necessary to figure out why the ceiling primer needs, how to buy paint, and how to primer the ceiling before painting correctly.

What is a primer? This mixture (colloidal solution) consisting of a special substance capable of creating the finest film membrane on smooth surfaces for the convenience of further repair (construction) works. In our case, the painting of the ceiling.

Processing such a soil mixture allows paint to bed smoothly and tight, because The film formed by the soil has also adhesive properties, i.e. increases paint grip with horizontal surfaces of ceiling plates. Adhesion guarantees even applying the coloring solution and significant savings!

A huge plus for the ceiling primer is the presence of antiseptics in it, which do not allow to multiply a mold mirina, which is able to poison the joy of existence not only by appearance, but also significantly pouched up health.

Selection of primer

The composition of deep penetration

What to progress the ceiling? Inspect the cleaned surface. If it is covered with multiple cracks, and the composition of the concrete leaves much to be desired (it crumbs or its surface is melted with a mass of small holes), it will have to use the primer of deep penetration.

The name speaks for itself: the primer penetrates as deeply as possible in the pores of the plate, literally enamels into the slots and cracks to a depth of 1.5-2 cm, grasping the hearty solution. It aligns and smoothes the surface, providing high adhesion, and allows you to evenly apply any paint. The ceiling will evenly absorb moisture, it means that there will be no dry or overly wet "islands" during color. And the paint layer will last long, will not fly away and won't go blisters!

The primer of deep penetration is an excellent option not only for porous concrete, it is also suitable for iron sheet, and for wooden beams. For smoother, less specific surfaces, other primer mixtures are fully suitable.

Alkyda

These primers are the most durable and therefore reliable, besides the basis of mineral. Alkyd soil is used for fiberglass facing, tiles, galvanized steel and bricks. In addition, the composition of alkyd mixtures includes plaster, cement and lime. You might think that it is better for the ceiling than an alkyd soil, and it is difficult to come up! However, it is desirable to use it in well-ventilated premises, and in some cases (children's bedroom) is generally undesirable.

Alternative - primer under enamel. It consists of lacquer and resin fillers, often add painting pigment in it. Working with such a mixture is easy and safe, despite the fact that the solvent for it is solvent or xylene.

From resin and olifa

Such primers "love" wooden ceilings and metal surfaces. The primer is prepared from natural and artificial resins and oils. These primer mixtures may not contain moisture-resistant and anti-corrosion additives - be careful, stopping your choice on them!

Quartz

The ceiling primer before painting this mixture will give the effect of light roughness, on which any decorative plaster will easily fall. And all because the composition of such a mixture enters the sand. The larger the sand, the more expressed the grungy effect.

Latex

The main purpose is to prepare a ceiling of "unreliable" materials, be it plasterboard or chipboard. It is best to add lime to such a mixture if the use of water colors is planned, and at the same time "set tone" under the selected kel. What part of the lime and to which material should be added - it is written on the instructions for each primer, since the ratio of synthetic latex and the water base may differ from each manufacturer.

Vinyl Acryl

This emulsion solution wonderfully "finds a common language" with old ceilings. The modification of silicone with vinyl acrylic copolymer gives an increased waterproofing of ceiling floors, without canceling all other primer "obligations". Equally adhesibly sticks both to a clean surface and to previously plastered ceilings.

Pure acrylic primers are good for all species and materials that are subject to staining by any paints. But! Primer for the ceiling under the painting of water-level paint should be applied on a water basis.

Universal

These primers work perfectly on any surface, with any material, from anything your ceiling. Such primer mixtures of the road, but the price of them is quite justified.

On video: how to choose the primer.

Homemade billet.

You can prepare the primer on your own, at home, from the remedies:

Option 1: Mixing PVA glue and a conventional putty to obtain a homogeneous liquid mass.

Option 2: Combine the selected paint with a suitable solvent.

In the second embodiment, the ceilings after can and do not paint, for which they are applied to the first layer strongly diluted composition 4x1, and the second layer - 1x1. If you wish, you can still "walk" the diluted paint on the third layer, but, as a rule, the second primed layer is quite enough.

Based on which material is used for the "manufacturing" of the ceiling, which finish is assumed in the future (tile, painting, etc.), choose which primer mixture is suitable for our ceiling and proceed to priming.

What else can you need?

The bucket under the mixture should be wide enough so that the roller in the width was fully in it completely. High ceilings? - We got stuck with a roller extension - a telescopic handle. By the way, the roller and the brushes can be replaced with the paint.

Now read the instructions, how to apply primer to the ceiling:

  1. Interpose the primer as written by the manufacturer. Soil under the water-liquid paint weighing water, the rest is a suitable solvent. Mix thoroughly.
  2. If the ceiling is perfectly even and does not require minimal additional actions, we will stop on the acrylic mixture - it will be enough. You need to apply a thin layer and give it to dry.
  3. Skat the joints (if they are) and small cracks acrylic putty. We are waiting for the shit and sanding places.
  4. Be sure to remove dust! To help us - a second, aligning, grabbed small particles of a layer of primer. Breed the second layer especially carefully so that there are no divorces. The roller here has an indisputable advantage over brush.
  5. Since the polymer dispersion of conventional soil mixtures is not absorbed into the ceiling, but only impresses the upper layer, hanging on it, should not be applied in a lot of layers, it will prevent paint. The paint also does not absorb in the primer, and dries on it with a smooth layer.

So how many times to primer the ceiling before painting? It is enough twice with a break of 3-4 hours after the shtlock.

Modern primers often go with a weak color indicator, in the depth of the color of which, after applying, it is easy to determine how uniformly covered the ceiling with soil. This will greatly facilitate your work. Such an indicator does not affect the adhesion and fungicidal properties of soil and paints.

Types of primer (1 video)

Often, many newbies when performing independent decoration of the room, they forget that the primer process is also important as its finish. The primer of the ceiling with its own hands provides a much higher-quality and reliable coupling of all types of finishes, ranging from plaster and ending with color.

How to Priminate Graphs: Types of Primer

In the event that the primer mixture is applied to the concrete surface, the types of primer are allocated as follows:

  • With deep penetration . As a rule, many ceilings having a concrete as the basis, the layer of plaster or putty are processed before finishing. In order for the finishing of the mixtures with tight fastening with the ceiling surface, it should be predetermined to impregnate the surface of the primer of deep penetration. In addition, a large amount of these type primers may also contain antibacterial additives that prevent the spread of the fungus indoors.
  • Strengthening . Such should strengthen the surfaces that may turn out, since it contains a large amount of adhesive substance. It not only penetrates the sleeping surface, but also glues it. It must be borne in mind that such a mixture cannot be used on smooth surfaces, as in the case of excessive formation, they will create a film on the surface, which will worsen the tensile coupling.
  • General purpose . Such mixtures are used already in the final finish. Since they allow you to make a stronger coupling layer of the decorating layer of the decor, as well as minimize the consumption of any material for the coating, be the glue or paint.

As for the cases when a tree acts as a basic overlap, only two types of primers are distinguished:

  • General purpose . Provides a smoother surface of the tree, as well as minimizes absorption, which makes it possible to improve the strength of the hitch and reduce the consumption of building materials. Moreover, such a primer will prevent the rotting of the wooden surface.
  • Special impregnating . Also allow the surface from the rotation process, as well as from harming various insects.

Taking into account all the above, we can conclude that you know how to properly grind the ceiling, it is very important. This will ensure a beautiful appearance of the ceiling, both outside, so in the photo and video. When applied to the concrete surface, it is necessary to apply both the primer of deep penetration and general purpose. The latter is applied after putty.

It is also necessary to pay attention not to the fact that even if a suspension design is selected as a finish, it is still not necessary to forget about the primer, since such mixtures will prevent the appearance of fungus on both surfaces.

How to Priminate Ceiling: Preliminary Actions

Prior to the start of the primer process, it is necessary to pre-deliver the ceiling surface from the previous finish (paint, whitewashes, covering plaster). And also thoroughly rinse and give to dry.

It is important that the fact that it is worth removing the premises to be removed in which the process itself will be carried out. If cleaning is carried out at the projected ceiling, it is impossible to ensure that the rising dust particles are not attached to another low layer, which will reduce all the efforts.


Preparatory steps are as follows:

  • When buying a ready-made mixture, it simply pour it into a special container and prepare a roller.
  • When purchasing a concentrate, we break it according to the method that is shown on the package.
  • An alternative variant of the primer can serve a mixture of water divorced plaster to the consistency of liquid sour cream. However, this option is very risky, therefore, it is necessary to still acquire special mixtures, preferably one firm with putty.

In order for the ceiling is beautiful and neat, be sure to not only make the cracking of the cracks on its surface, but also to be primed. The ground mixture is called a solution consisting of a film-forming substance and coloring pigments. It is used to align the surface of the ceiling. In the event that the unevenness of the ceiling is minimal (up to 3mm), the primer is used, which is as deeply entered into the surface.

On the other hand, the question arises, and what is the ceiling primer, why you need to use this solution, and nor any other. Such a mixture is widespread during the finishes of the ceiling surfaces due to the fact that it perfectly binds moisture. This property allows the ceiling to evenly absorb moisture when painting, not leaving too dry, or too dipped paint areas. In addition, paint can, simply, fly from the ceiling, creating unsightly holes in the facing.

Types of primer ceiling

Based on the surface, the necessary mixture is selected. Some ceilings are greater than others, some of the different nature of the material (wood, reinforced concrete, brick, cement, plaster, fiber).

For any occasion there is an optimal option:


Also, they should be kept in the mind that the primer under the enamel is much better suitable for interior rooms rather than an analogue based on an alkyd resin that is better to use outside the buildings.

Classification of primer applications

Primers are divided not only by cooking material, but also by the scope of their application. In order to understand what kind of primer is better for the ceiling, you will need to determine what the ceiling would be to bind.

Based on this, the selection of a certain type of solution will be taken, which are:

  • Grinding under water paints
  • Groundovka-Universal
  • Spec-primer
  • Primer under enamel
  • Primer mixture


Having understood with the names of each type of primer mixtures, you can proceed to their direct description:


How to primer ceiling, details on video:

How to primer ceiling

Such a process can be carried out both manually and using special tools.

For applying layers of solution, the following items will be needed:

  • Of course, it will take the protagonist of such works - the primer itself.
  • Bath for roller. It is necessary to take into account its size so that it perfectly coincided with the roller.
  • The roller itself, the brush, you can be replaced by the crawle. For high ceilings, you will need a roller extension. In order not to leave the traces, the last layer will need to be applied not to a brush, but roller.


Having collected the whole toolkit, work begins. To prevent the blur or unreliability of the primer, it is not recommended to add water more than spelled out on the label.

So workflow:

  • The initial layer is best to apply not parallel to the rays of sunlight falling into the room window. Next, on the contrary, the layer is applied in parallel.
  • Proper application depends on whether the appropriate primer for the ceiling was selected. In addition, before applying, it is necessary to clean the surface from dust, rust, dirt and fat, as well as to dry it as much as possible. The tree is better to sand.
  • The subsequent layer of solution must be applied to the Occhat first. Next, it is necessary to level the resulting surface with a spat.
  • If there is a need, then you can apply another layer of primer, before you begin to flicker the ceiling. This will make it possible to achieve the smoothness of the paper level ceiling. However, even the covered ceiling in two layers is already ready, often to further finishing and painting.


The correct answer to the question "What to choose a primer for the ceiling" can only give the ceiling. Based on its properties, you can determine the most appropriate option, which will serve as a possible period of time and will delight with its beauty every day. In addition, the ideal choice may also save a significant amount of money, since in some approaches you can do with one priming, without spending money to paint the ceiling.
