What primer to use on walls before wallpapering or painting. Which primer is best for walls under wallpaper Which primer is best to use under wallpaper

Or wallpaper - work that is always carried out before further finishing. Such events are mandatory regardless of what the “finish” coating itself will be. But many either skip this stage altogether or treat it with disdain.

Why is a primer necessary before wallpapering?

Thanks to this composition, it is easier to make the walls monochromatic. In addition, it will allow you to get rid of almost any defects on the main surface. This is especially true for transparent and light wallpaper.
Primers allow you to completely isolate from the finish areas where dust and dirt can accumulate.
This composition will fill all the pores of the source material. Thanks to this, the glue itself will not penetrate into them. Which improves the quality of “grip” with a roll of wallpaper.
In general, the reliability of adhesion between different materials increases.

If you do not pay due attention to finishing at this stage, the results will not keep you waiting.

What should you consider when choosing a primer?

Soil is a suspension in liquid form. When applied to walls, it penetrates 2 cm or further into the partition. Deep penetration concentrate is used for walls with a very durable surface. Perfect solution, if you need to get a strong and smooth surface.

Which primer to choose for walls under wallpaper? Depends on the material from which the walls themselves are made.

Regular wallpaper glue is the cheapest and affordable solution. It reduces the ability work surface absorb moisture.

But buyers don't receive additional protection from stains and dirt. This impregnation is most suitable only for perfectly smooth substrates.

There are many types of primer on the market that can be used to treat walls. In addition to the wall material, it is necessary to take into account not only the humidity in the room, but also the time that buyers are willing to wait until the composition dries.

Several types of composition can be distinguished depending on the constituent components:

Perchlorovinyl
Mineral
Glyphthalic
Alkyd
Acrylic

Choosing a primer for wallpaper based on composition

More details about each group

Before applying to the surface raw material must be completely cleaned of chips and dirt. The quality of the result and wallpaper sizing in general largely depends on what composition was chosen in a particular case.

Acrylic compositions are considered the most universal. Often used during the preparation of plywood and wood, brick and concrete walls. But it is forbidden to apply it to walls that contain ferrous metal. What about the main characteristics?

Dries in 5 hours
A universal solution for all surfaces
No smell
Easily dissolves in water

Most often, wood-based surfaces are treated with alkyd primers. This is an especially relevant option for those who live in country houses. After applying the composition, a layer is formed on the surface that easily holds not only wallpaper, but also other finishing materials. Alkyd mixtures themselves are divided into several types according to composition.

With zinc phosphate. The partitions are impregnated before the final painting of the walls.
With zinc chromate.

Alkyd compositions have the following main parameters:

Dries in 15 hours
You can apply them before laying tiles
Suitable for further painting and wallpapering
Can be used for both interior and exterior surfaces
Provide perfect grip

If you need to work on metal or wood surfaces, ideal option will become glypthal impregnation. In fact, this is generally the only type of soil that allows high-quality processing hardware. Anyone who plans to wallpaper the inside of a garage built specifically from metal should choose this type of primer.

For concrete, brick and wooden walls use acrylic primer

About adhesive varieties

Literally a dozen years ago, any housewife could prepare a paste, which was most often used in working with wallpaper. They applied it in two layers, only after that they moved on to strips of material.

Therefore, you can often come across advice according to which it is enough to spread glue on the wall and cover everything on top with wallpaper. Such statements are true, but only partially.

On the modern market, many manufacturers offer their own version of the mixture. The specifics of application and components can be completely different. You don’t have to separately purchase a wall primer for wallpaper if it is written on the adhesive that it can also perform this function. If there are no such references, the treatment is carried out only with compounds recommended for this type of work.

What to do with liquid wallpaper?

In terms of consistency and composition, liquid wallpaper is the same as decorative plaster. This design is based on cellulose and silk type fibers.

A white suspension or a transparent emulsion is what you can use to prime liquid wallpaper. In order to completely level the surface, you will need up to 3-4 layers of material. This will help in the future to avoid stains that may appear after rolling with liquid wallpaper.

A primer containing quartz dust is applied to an absolutely smooth surface. Thanks to this, there will be no breaks, roughness or structure. The material will lie flat. You can prepare this composition yourself. It is enough to add quartz or marble dust, clean sand to the usual impregnation.

For liquid wallpaper use a primer with quartz dust

More details about acrylic compositions

They can work perfectly with concrete, plaster and putty on walls. They always get the job done.

“Deep penetration primers” are ideally suited for situations where the wall surface has not undergone the highest quality treatment.

But conventional developments also cope well with their responsibilities.

It is important to really choose high-quality compositions. It is better to trust well-known companies, this will help avoid troubles in the future. Inscriptions like “for wallpaper” are just a marketing ploy, so you definitely shouldn’t trust them.
Stores often sell regular PVA glue under the guise of a special primer. You should not purchase products that do not contain acrylic polymers at all.

Pros and cons: is a primer always necessary?

Few people dare to spend money on purchasing such special compounds. After all, many manufacturers guarantee one hundred percent results even when using conventional glue. Indeed, applying a primer layer may not be considered necessary in every case.

When performing temporary repairs, you can completely do without applying primer. Or when the wallpaper itself is not designed for a long service life.
Are you purchasing light, paper finishes? Then you also don’t have to spend money on a primer. An ideal result cannot always be guaranteed, even if a special composition is used.

The adhesion of materials is increased thanks to a high-quality wallpaper primer. This means that the material will connect faster and better to the base. Primer compositions completely penetrate even the smallest pores. This ensures that much less glue is consumed in the future. In the majority modern means Substances with an antiseptic effect are also added. This means that you don’t have to worry about fungi appearing under the wallpaper.

We improve the adhesion of materials by priming

But the material will lag behind the walls, even if the technology is slightly compromised.

A primer should definitely be used when working with heavy wallpaper. Then special materials will help strengthen the base and ensure higher adhesion rates.

At the same time, repair costs will practically not increase. On the contrary, you will not need to buy special glue.

Methods for priming walls before wallpapering

PVA glues are indeed cheaper than other compounds, but that’s where its advantages end. It does not penetrate deep into the pores, it only creates a protective film on the surface. If the base collapses, the same fate awaits the film itself.

We use PVA glue as a primer only if we have a limited budget.

He can help out only if the repairs are temporary, or the owners have serious restrictions on the funds invested. The main thing is to trust only trusted manufacturers so that the result meets your expectations. IVSIL, Knauff, Prospectors - these are just a few names that have long stood the test of time. When purchasing formulations from a little-known company, you need to pay special attention to the composition.

For further work, you will need to purchase not only the primer itself, but also a brush for applying the composition in hard-to-reach places, a bath, a paint roller with a coat made of velor, pile or foam rubber. The telescopic handle is much more convenient to use than a stepladder. Depending on the porosity of the walls, soil consumption can be about 100-200 ml per 1 sq.m. It will take several hours for the material to dry completely. After this, the wallpaper can be glued immediately.

Many craftsmen advise first checking the moisture content of the putty and the plaster itself. You just need to cut a square with sides of 10-15 centimeters from plastic film, attach it to the wall with a brick. The main thing is that under inner space no air penetrated this film.

It is enough to leave the device for only 10-12 hours to see the first results. The walls have not dried completely, even if it is noticeable a small amount of moisture. If everything is dry below, then you can take the wallpaper and start gluing it.

The applied layer should not have a thickness greater than 0.4 millimeters. Loose and porous surfaces always require re-treatment.

Do you need to properly prepare the walls for gluing non-woven wallpaper? I will tell you what compounds can be used and how to apply them correctly so that your wallpaper stays strong and does not turn yellow over time.

Types of compositions and their features

To prepare walls for non-woven wallpaper, one of four soil options is used:

Acrylic compounds;
Alkyd primers;
Latex compositions;
Wallpaper glue solution.

Each decision has its pros and cons; it’s up to you to decide which primer to choose for non-woven wallpaper, so carefully read all the information below.

If you do not prime the plasterboard walls or the surface covered with putty, then the wallpaper will subsequently be peeled off along with the finishing or the protective layer of the slabs. Be sure to prepare the surface.

Option 1 - acrylic primer

This is the most popular composition today. It has a number of advantages:

Illustration	Description
	Availability. The composition can be found in any hardware store. The primer is sold in packages different sizes and can be either in finished form or in the form of a concentrate, which is diluted with ordinary water immediately before use.
	Low cost. For a liter of the composition you will pay from 60 rubles; this price is affordable for almost any developer and does not significantly increase the overall costs of the project.
	Easy to apply. The composition is diluted with plain water and applied to the walls with a roller or brush. The primer has virtually no odor, so you can work without using protective equipment; if it gets on the skin, the composition is simply washed off with water.
	Fast drying. Wallpaper can be glued 2-3 hours after applying the primer. This allows all work to be completed in one day. Of course, if you need to apply two layers, then the period increases, this is also worth taking into account.
	Improving the adhesion of wallpaper glue. The soil clogs all the small pores on the surface, reducing its absorption. Thus, the adhesion of the adhesive composition is significantly increased, while glue consumption is reduced, and savings can sometimes be up to 50%.
	Many composition options. The following types of soil can be found on sale: Strengthening; Deep penetration; With antiseptic additives; Increases adhesion.

If you have an uneven wall color, then choose a coloring primer; it will even out the tone and make the walls light. If you couldn’t find such a primer, then you can simply add 10-15% acrylic paint to it.

Option 2 - alkyd primer

This non-woven wallpaper primer has its own characteristics:

Illustration	Description
	Created from a composition of polymers. This option is not soluble in water, so when using it you need to use special solvents. The compositions are sold in completely finished form; before use, the composition is thoroughly mixed and, if necessary, diluted until the required consistency is obtained.
	Used for wood based materials. Alkyd primer is used for processing chipboard, fiberboard, plywood, wood, OSB boards and other similar elements. The composition can also be used to treat metal surfaces. This option is not suitable for plasters and putties.
	Paints a wall a specific color. The best composition for wallpaper is white, it is the one that is used most often. Be sure to pay attention to this aspect when purchasing, otherwise you may find that your primer is brown or gray in color, which is not suitable for creating a wallpaper base.
	Creates a thin film on the surface. Alkyd primer does not penetrate the material; it covers it with a thin moisture-proof layer. Most often, processing is done twice to ensure the best reliability.

Option 3 - latex primer

This primer for non-woven wallpaper began to be used relatively recently, but has already gained popularity for the following reasons:

Illustration	Description
	Strengthens the surface. This type of composition is ideal for loose substrates: plaster, old putty, drywall, etc. It can also be used for wood-based materials. High penetrating ability allows you to strengthen walls with minimal costs time and money.
	Does not allow moisture to pass through. For this reason, latex-based compositions are recommended for use in all rooms with high humidity. A moisture-proof barrier is created that protects the walls from mold and mildew.
	Closes pores well. If you have a concrete wall with many pores, then latex primer will seal them, thereby reducing the consumption of wallpaper glue and improving the adhesion of the composition.

Option 4 - primer with wallpaper glue

For the work, the same glue is used to glue non-woven wallpaper. The only difference is the application process:

Illustration	Description
	Uses standard glue. In this case, you need to purchase one and a half times more composition than required, since part of it will be used for surface preparation.
	. To do this, the glue is diluted in warm water. Everything is done in the same way as usual, with the only difference that water must be used twice as much as normal. The liquid is poured into a container, then glue is added to it with continuous stirring. After stirring, the composition is left for 10 minutes, then mixed again.
	Glue is applied to the walls with a roller. The composition is evenly distributed over the surface in one layer. It is important to ensure that there are no smudges left on the walls. You can continue work only after the surface has completely dried, this usually takes from 4 to 12 hours.

This option can only be used for strong, flat surfaces; if the walls are porous and loose, then it is better to use specialized soil.

Do not use PVA glue to prime walls under non-woven wallpaper. Although it creates a durable film on the surface, yellow spots may subsequently appear on the wallpaper.

Application technology

Let's look at the technology of applying primer. Instructions for applying the compositions with your own hands are presented in the form of a diagram; below, each stage is described in detail:

The surface is being prepared. Before priming the walls before gluing non-woven wallpaper, it is worth removing the remnants of the old coatings from them and filling up all the unevenness with putty. The final stage of preparation is to clean the base from dust using a vacuum cleaner or a regular broom;

Preparing the primer composition. The preparation process depends on the type of soil. All the necessary information is usually indicated on the packaging, and I described the option using wallpaper glue in detail above. Most often, you just need to stir the solution; if it’s a concentrate, then dilute it;
The tool is being prepared. For work, it is best to use a roller and a paint bath, as in the photo. To reach the top of the walls, you can take a ladder, or you can use a special extension handle. Along the perimeter of the room, the floor is covered with polyethylene to prevent splashes of primer on it;

The first layer is applied. Everything is simple here: the soil is evenly distributed over the surface, the pressure on the roller is moderate. All smudges are removed immediately, the wall should be damp over the entire area;

After drying, the wall is checked. Just run your palm over the surface - if there are grains of sand or putty particles on it, then the treatment is repeated. If your hand is clean, you can glue wallpaper.

Conclusion

You have learned about all the soil options for non-woven wallpaper and can prepare the wall on your own. The video in this article will tell you about some important aspects in even more detail; if you don’t understand something, ask in the comments.

The primer in front of the wallpaper protects the surface of the canvases from the appearance of mold, protects them from the development of many biological pests, improves the quality of adhesion of the material to the wall surface. Therefore, this stage should not be neglected when carrying out repairs. The article will tell you what primers there are for wallpaper, their advantages and disadvantages, and methods of application.

The primer is a special liquid solution that is used for pre-treatment of the surfaces of walls and ceilings before any finishing coating.

Wall priming is performed in order to:

Isolate dust particles with a layer of primer.
Reduce and distribute the absorbency of the surface more evenly, reduce the porosity of the walls. This will make it possible to apply glue and paint in an equal layer and will reduce the consumption of glue under the wallpaper.
Increase the efficiency of wallpaper fixation.
Increase material adhesion and strength.
Save paint and varnish compounds.
Give the surface greater wear resistance and water resistance, which will protect the base for a long time.
Create antibacterial protection. The primer contains special additives that prevent the growth of harmful bacteria and fungi (see Antifungal primer - purpose and characteristics of the material).

Advice.If mold has been noticed on the walls, it is imperative to treat them with an antibacterial primer. Walls should always be primed. It doesn’t matter if they are painted, wallpapered or covered with decorative plaster.

The primer used before wallpapering helps to make the surface better, and its service life will be much longer.

Types and features of primer

When choosing a soil, it is necessary to choose a deep penetration soil. Also an important criterion is the water resistance of the soil, since wallpaper glue is mainly water with the addition of glue. The soil must be strengthening, because for interior work As a rule, gypsum materials are used, and gypsum is not highly durable (plasters, putties) unlike cement. Particular attention should be paid to antiseptic or anti-mold additives.

The modern market for finishing mixtures offers a wide variety of primer compositions.

The composition is available in two consistencies:

dry. Before gluing wallpaper with your own hands, the composition is diluted with water. The instructions for use indicate how much material will be needed per square meter processed area. This takes into account the number of layers applied and the quality of the wall;
liquid. Its price is higher than the dry mixture. The coating is ready for use. It is a composition of a homogeneous mass, which includes various universal fillers.

The type of wallpaper primer is:

Acrylate. Universal deep penetration primer based on acrylates. Does not create a film, which is important for the walls to “breathe”. Strengthens the base well and reduces the consumption of wallpaper glue. Has highly penetrating ability. Acrylate primers are also economical in consumption.
Acrylic. This soil consists of acrylic polymers and is universal. It is used for application to walls made of plasterboard, wood, concrete, paint, asbestos cement, and plaster.

Types of bases:

Gypsum plasters, putties. It is necessary to prime at least twice, because the base is highly absorbent and not the most durable. Provided that we have chosen the soil good quality from a reliable manufacturer, for example or . We treat the gypsum base with these primers twice; this will be quite enough to prepare it before gluing wallpaper, including heavy vinyl.

GLIMS DeepPrime Primer or GLIMS Prime Primer is ready material, which does not require the addition of solvents or water.

Antiseptic additives included in the primer prevent the growth and spread of fungus and mold. That is why such primers are very recognizable and in demand among builders.

Cement plasters and putties. This type of base does not have such a strong absorbing ability as gypsum; it is enough to prime it with this primer once and this will be enough for wallpapering. These primers are also suitable for painting or wallpaper with subsequent painting.

The solution can be applied with a brush or roller.

Preparation for applying primer

Before starting work, you need to decide which primer to choose for the wallpaper, determine it functional features, find out how long it takes to glue wallpaper after priming?

To do this you need:

Run your palm over the surface of the wall and see if there are traces of plaster or a white coating on it; you will need primer used for deep-penetrating chalk bases.
Determine the density of the old layer of finishing on the wall. To do this you need:

wet the wall with water;
determine the places where it is most quickly absorbed. They must be primed in several layers.

Before making a primer for wallpaper, it is imperative to inspect the surfaces for the presence of mold or mildew, which requires a special primer that destroys fungal spores and prevents their development. It is applied over and under plaster.
Low-porosity walls are primed with a material with increased adhesion properties.
Porous and loose substrates must be treated with compounds that have a critically high penetration effect.

Tip: Walls under wallpaper should be primed in several layers. Before carrying out the process, it is necessary to calculate how much consumables required for work.

For this:

The area of the entire surface to be wallpapered is calculated.
The resulting value is multiplied by 1.5, this is how much primer will be needed to apply one layer. But first, you should read the manufacturer’s instructions to determine what kind of primer is used for wallpaper, how long it takes to dry, and its consumption per square meter.

It is better to use the following recommendations before work:

The bucket is being prepared.
The mixture is poured into it.
A plastic painting mesh is installed, which will help squeeze out excess liquid from the brush or roller in order to save solution.
Hard-to-reach places are treated with a brush.

Each layer must dry thoroughly before applying the next. The dry coating will be smooth and slightly tacky to the touch.
The primer should be applied from top to bottom.
Floors should be covered with polyethylene. Any mixture is an adhesive that will be quite difficult to remove from floor coverings.

How to prime walls

There are several recommendations for carrying out repairs, including preparatory work.

These include:

The walls are inspected very carefully for the presence of chips, small potholes, all kinds of irregularities and other defects. They are subject to plastering, puttying, sanding and drying.
A primer is selected. It is better to use an alkyd primer adapted for wood or a glyphthalic primer, which is best used to treat metal surfaces or wood located in a relatively dry room. Universal remedy– acrylic primer, suitable for protection on any base except metal.
Before priming, it is necessary to take measures for personal safety:

close your eyes using safety glasses;
cover your head;
wear rubber gloves.

Read the instructions from the primer manufacturer. Some recommend mixing the composition thoroughly before use. In this case, you can use special devices or electric drill with an original attachment that imitates a mixer.
Since the primer is a liquid composition, to avoid splashing it must be poured into special containers such as a trough in small portions.
When working, it is better to use soft rollers with long handles, as in the photo, so as not to use additional tables and chairs to support a person.

You must be very careful to ensure that the mixture covers the entire surface of the walls, without leaving “bald spots.” If there is a danger of making a mistake, a pigmented primer can be used.
The walls must be dry, and only after that you can glue the wallpaper.

The video will tell you how and what you can use to prime walls under wallpaper, and what kind of primer is used for non-woven wallpaper.

Why do you need a wallpaper primer?

A primer for wallpaper is intended to bind the existing small layer of dust on it and strengthen the loose surface of the material. Do I need to prime wallpaper before painting? After all, the primer penetrates deeply into the wallpaper, reaches the adhesive layer and destroys it. After drying, primed wallpaper may warp.

However, there is a small advantage:

Wallpaper covering can absorb paint strongly. The wallpaper is primed to even out the absorption of the coating.
The consumption of coloring material is reduced.

In each case, you should carefully study the instructions to determine whether the wallpaper needs to be primed before painting. If priming before wallpapering is neglected, then within a year they may fall off, and when painting the wall, they may peel.

Over the course of many repair work The priming stage is mandatory, and this does not always depend on the material at the base of the structure, but more often on a complex of factors. Which primer is best for walls under wallpaper? — It is impossible to give a definite answer to this question, because several factors need to be taken into account. important nuances. In a nutshell, you need to take into account what kind of wallpaper you will be gluing and on what surface. In this article we will look in detail regarding the right choice soil covering of walls.

Why is it worth priming walls?

Is it really necessary to apply this very primer, because previously during repairs they managed just fine without it. Maybe this is an invention of marketers to pump out money?

We have to disappoint you, you will have to fork out for the ground. After all, we live in the 21st century, so we are unlikely to glue paper wallpaper to newspapers. In the building materials market, buyers have long given preference to vinyl, non-woven, liquid and paintable wallpaper. They are much heavier than paper ones. In addition, the walls of modern houses are no longer limited to concrete and brick. This can be plasterboard, gas and foam blocks, expanded clay concrete, different kinds putties, plasters. And all these materials require your own approach in order to combine the surface and type of finish.

Important! What is the best way to prime the walls before wallpapering? If you want to do redecorating made from cheap materials, you don’t have to spend money on a primer. Under paper wallpaper on brick or concrete wall Instead of primer, wallpaper glue or PVA glue diluted with water (1:7) will do just fine.

But if you want to do everything efficiently and correctly, then be sure to cover the walls with a primer. In this case, priming the walls with glue before wallpapering would be a bad option.

What is a primer used for?

Primer is an intermediate link between finishing and the basis. This link plays important role for all repairs. So what does a primer do?

Increases wall adhesion and finishing materials, wallpaper, for example.
Impregnating the wall with soil reduces the consumption of wallpaper glue.
The soil increases the moisture resistance of the wall without reducing air circulation.
The soil additionally levels the surface of the wall, filling pores, cracks, and small irregularities.
Applying a primer is an additional dust removal of the surface after preparatory work.
Good primers usually contain drugs that prevent the formation of fungus, mold, and rust.
The soil prevents the bottom layer of wallpaper from delaminating.

As you can see, primer has a lot of advantages. In addition, applying it to the wall is not particularly difficult. You just need to stir it in a bucket and roll the wall with a roller.

PVA glue for priming walls under wallpaper, like wallpaper glue, can be considered as an economical primer option. But they don’t perform as many functions - they only slightly improve the adhesion of the wall to the wallpaper, and then they are not suitable for all types of surfaces.

Important! For a painted, wooden or metal wall, you will need a special primer; PVA will not help here.

Types of primers

There are two groups of soil:

adhesive - improves the adhesion of two surfaces;
strengthening - holds surface particles together and fills pores.

But by type, soils are divided according to the surface on which they are applied:

Acrylic.
Alkyd.
Glypthal.
Mineral.
Perchlorovinyl.

By appearance they can be in the form of a liquid solution, concentrate or dry mixture.

Important! Before making a purchase, measure the area of your walls, since the container with soil is designed for a certain square area. Do not forget to take into account the number of layers that will have to be applied - it depends on the characteristics of the surface.

Now let's look at each type of soil in more detail.

Acrylic (emulsion) primer

Probably the most universal of all, as it is suitable for most types of surfaces: concrete, brick, wood, plywood, even loose plaster.

Important! The only surface that is not intended for acrylic primer is one containing ferrous metal.

Features of acrylic primer:

Acrylic primer for interior work is easily soluble in water and has no unpleasant odor and dries quite quickly (from 2 to 5 hours).
There are several varieties of this soil:
1. impregnating - designed for impregnation of a loose base up to 10 cm deep;
2. strengthening - does not penetrate deeply, is needed to bind the fine fraction on the surface, that is, it strengthens the base;
3. adhesive - lays on the surface with a dense film and levels the base.

Important! Good soils The products of the companies “Primer”, “Kompozit”, “Osnovit”, “Knauf”, “Perfecta”, “Starateli” are considered.

Alkyd primer

Designed for wooden, even previously painted (indoors) and metal (indoors and outdoors) surfaces.

Important! Durable alkyd primer can also be used on galvanized steel, glass and tiles. But it is not suitable for plaster and drywall.

Features of alkyd primer:

This primer is soluble in organic solvents and therefore has a characteristic odor. It dries in 10-16 hours.
They are divided into those containing zinc chromate and those containing zinc phosphate.
Intended for wooden surfaces - they fasten wood pores, reduce absorbency, prevent fibers from swelling, and also protect against rot and mold.
Primers intended for metal transform rust and prevent its further spread.

Important! Such soils are represented by the brands “Kompozit”, “Aura”, “Tikkurila”.

Glyphthalic primer:

Suitable for wooden (wood and lumber) and metal (ferrous and non-ferrous metals) surfaces, to prepare them for painting.
Designed for surfaces that are more or less resistant to moisture.
The coating is homogeneous, hard, anti-corrosion, with a high degree of adhesion.

Important! The oldest primer in this series is GF-020; now they use GF-0119 and GF-021 instead (there is a quick-drying type). This coating takes about a day to dry.

Mineral primer

It is made with the addition of lime, gypsum or cement. It is used for processing concrete (also expanded clay concrete), brick (including gas silicate brick), and also plastered surfaces.

Features of mineral primer:

After application, it fills the surface pores well.
It dries in literally a couple of hours.

Important! At high humidity Drying time indoors may increase.

Primers from Primer, Remmers, Ceresit, and Caparol have good reviews.

Perchlorovinyl primer

Designed for brick, concrete, metal surfaces. Suitable for interior and exterior work. Most often it is used for metal surfaces that are covered with scale and rust.

Features of perchlorovinyl primer:

In warm conditions it dries quite quickly, about an hour.
This primer contains toxic substances, so its use in residential areas is undesirable.

Important! There are also these less commonly used types of soil:

Polyvinyl acetate - intended for concrete, brick, drywall and stone before applying polyvinyl acetate paint.

Phenolic - intended for metal and wood before painting. Toxic.

Polystyrene - for plaster and wood. Toxic.

Wallpaper primer - which is best for preparing a wall for wallpapering?

Let's dwell on which primer to choose for walls under wallpaper:

Practice shows that acrylic primer is in greatest demand as it is the most versatile, easy to apply, non-toxic and without a strong odor. It suits most walls; it is also used before applying liquid wallpaper, although in this case the primer is applied in several layers.
If you are gluing wallpaper not in an apartment, but, for example, in a garage or in a country house, where conditions are not quite standard, then study the features of all types of primer and choose the right option.

We prime the walls for wallpaper

To do everything in order and correctly, you need to prepare in advance necessary tools and study the process itself in detail.

Necessary equipment for work:

Bucket to stir the mixture.
Bath.
Roller. Preferably with telescopic handle so that you don’t have to carry a chair or stepladder with you.

Important! The surface of the roller attachment can be made of foam rubber, velor or pile.

Brush. Needed for corners and hard-to-reach places.

Sequence of the priming procedure:

Before priming, it is necessary to prepare the surface. To do this, you need to clean the walls of sockets, nails and screws, old wallpaper, whitewash and plaster. If the wall was previously painted, the paint must be removed.

Important! Oil paint It’s more convenient to remove it with a spatula or a special scraper - it will fall off in layers. But water-based paint is more difficult to remove; you will have to clean it with sandpaper.

When the surface is clean, mix the primer according to the instructions, pour a portion into the paint bath and begin applying it to the walls with a roller.
Apply enough primer to the roller so that it does not run down the wall in streams.

Important! There should be no drips, but also make sure that there are no dry areas left. The surface of the wall should be evenly covered with soil. Coat hard-to-reach places with a brush.

Next, wait for the first layer to dry.

Important! Each type of primer has its own drying time.

If necessary, apply the second and subsequent layers.
Only after the surface is completely dry, proceed to finishing it, for example, wallpapering.

Useful tips to help you avoid the most common mistakes:

Do not apply dispersion or water-based paints instead of the appropriate primer.
Take your time to glue the wallpaper; let the soil dry completely.
Try to always apply two coats of primer, as you may miss some areas during the initial treatment.
When choosing a primer, correctly match the type of surface and type of finish.

It is better not to skip the stage of priming the walls during the repair process, because this is a kind of guarantee of the quality of the cosmetic coating. Priming with glue before wallpapering is not always suitable; in most cases it will be better to purchase specially designed raw materials and treat the walls with it. The recommendations from this article will help you choose the right one and carry out the work.

One of the finishing materials associated with wallpapering is wallpaper primer. Primer of walls under wallpaper is preparatory stage which should not be neglected. However, not everyone uses a primer before wallpapering walls. In this regard, the question arises of what primer does and whether it is necessary to prime the walls before wallpapering.

Priming the walls is an intermediate stage between putty and further finishing work.

As for wallpaper, preliminary priming of the walls will ensure high-quality gluing: Thanks to the primer, the glue will be distributed evenly, its consumption will be less, the adhesion between the wall and the glue will be stronger, the wallpaper will stick stronger. Since there are practically no perfectly smooth walls, wallpaper glued to an unprimed surface may, over time, reveal its flaws, become stained, or begin to peel away from the walls.

Saving on primer, in essence, means saving on the quality of wallpapering, since the technology requires its obligatory application to the walls.

Only high-quality painted surfaces and surfaces coated with durable finishing putties do not require primers.

Loose, crumbling surfaces especially need a strengthening primer. There are various types of primers that, in addition to strengthening, have other beneficial properties, such as deep penetration primers.
