Are the walls primed before puttying? Do I need to prime a brick, plasterboard surface of walls, ceiling before puttying

Repair is a troublesome business, and especially if you do it on your own, I want to avoid the unjustified laboriousness of work. In this regard, the question is often asked whether it is necessary to make the primer of the walls before filling them.

It all depends on what you want from a future repair. If you do not plan to redo everything soon, it is better that the primer of the walls before the putty is completed. In this case, your repair will be more durable. The appearance of the walls in this case will also greatly benefit, and the putty will not crack and crumble in the future.

How to prime walls

The market offers many types of soil mixtures, they can be dry or liquid. Not all mixtures are right for you. Some of these soil mixtures are suitable only for wood (alkyd and shellac). Many types are used for metal. Primers for metal protect the surface from corrosion. A separate primer is used for each type of metal.

If priming the walls in a living room, then a universal primer (acrylic or emulsion) is best. It is odorless and dries (under good conditions) in four hours.

The advantages of this primer include the fact that it does not have harmful impurities and is suitable for almost any surface.

If the walls are affected by a fungus, they can be treated with a special primer that removes mold.

In addition, all primers are divided into two groups - these are adhesive and strengthening.

Preference is given to one or another group, guided by the properties of the primed surface. For a loose and porous surface, it is more advisable to use a strengthening primer. They penetrate the primed surface by two to three centimeters and give the surface waterproof properties.

Adhesive primers improve the adhesion of the layers used. decoration materials. Such primers are used on fairly dense and finely porous walls, which do not absorb moisture very well. As a rule, they are good to use if in the future the walls will be painted, as well as for gluing wallpapers or tiles.

If we return to the question of whether it is necessary to prime the walls before puttying in the room, then wallpaper and paint, if there is a primer, will go better. The primer improves the bonding of materials, and, consequently, the quality of all further work.

Work stages

For priming the walls before puttying, they must first be prepared. For this:

• Old wallpaper carefully removed.

In order to make it easier to take wallpapers - you can wet the wallpaper, and also add a special liquid to the water.

Old paint and old plaster are also carefully removed. We pay attention to those places where the stucco does not hold well. We bring down the protruding places with a hammer.

• Stucco walls. At this stage, align the large bumps.
• We prime the entire surface of the walls that we previously plastered.
• Directly puttying the walls.

How to primer walls before puttying

For work, you need a bath under the roller or any suitable container, where we pour the primer. Need a roller and brush (both with a small pile), as well as a bucket, sponge and a respirator.

First, pre-cleaned walls are treated with a wet sponge. Pour the primer into the prepared container, and use the roller to apply it to the wall. Working with a roller is much more convenient. The primer applied by the roller to lay down more evenly, and the case will move more quickly. When working, you need to properly squeeze the roller.

The primer is applied in a thin layer. Smudges and accumulations of primer are not permitted. The primer is applied sequentially first vertically, then horizontally. For hard to reach places you need to use a brush.

After applying the primer, it must be allowed to dry. On the packaging, as a rule, the drying time is indicated. This time depends on the season (room temperature), the thickness of the applied layer and ranges from four hours to a day. After drying, the walls can be puttied.

Is the primer of the walls really important before the putty? The answer is obvious: without processing the walls, further work with the wall may not follow the scenario. After all, the primer not only protects the wall from the effects of harmful factors, but also contributes to a better setting of putty materials with the base.

The primer helps the putty layer adhere firmly to the base of the wall. Penetrating deep into materials, it improves adhesion and then putty lays on almost any surface without the risk of cracking or falling off.

Priming the walls

The primer contains components that protect the wall from fungus and mold, and prevent moisture absorption.

Manufacturers of building mixtures identify five primer tasks:

1. Alignment of the absorbing properties of the wall surface;
2. Ensuring the necessary level of setting of the top layer of finish with the wall;
3. Decrease in putty consumption;
4. Antibacterial protection;
5. Strengthening the treated wall.

The surfaces are primed not only before puttying the walls, but also before painting or wallpapering. So the finish will last longer without losing its original appearance.

What type of primer is better to use?

On the construction market are represented different types   primers that are designed to perform various tasks. It is difficult for those who are not engaged in construction or repair on an ongoing basis to choose the required type of composition.

  Types of primers

Perform the type of mixture that is suitable for processing this type of base. To understand which primer to choose, get acquainted with the main types of mixtures. Primer List:

• Aluminum primers are used exclusively for wooden surfaces to protect them from moisture and the spread of fungus;
• Alkyd. This type of mixture has been successfully used for processing metal and wooden structures;
• Shellac. Used for wooden surfaces to prevent the release of resins from wood;
• Silicate mixtures are used for processing decorative plaster;
• Acrylic Universal type of mixtures suitable for processing concrete, plasterboard, brick walls. Deeply penetrate the base;
• Epoxy mixtures are used to treat concrete and iron surfaces. This type penetrates well into the processed material and prevents corrosion:
• The polyvinyl acetate mixture is used during subsequent surface painting with the appropriate type of paint;
• Specific formulations. For example, a mixture for treating the surface of drywall.

When buying a primer, information on the packages is compared. Manufacturers indicate the depth of penetration of the mixture into the material. And the better the absorption, the better the result.

  This kit is enough to work with flat surfaces.

Getting started preparing the wall for putty

Before starting work, prepare the wall, cleaning from dust and previous coatings. If necessary, degrease and grind problem areas of the wall. Then proceed directly to the primer walls. To do this, you need a standard inventory:

• Construction brushes;
• Roller;
• Spray gun.

The spray is used when the primer before the putty occurs in large areas. In the case of small rooms, standard rollers and brushes are enough. The roller speeds up the application of the mixture on smooth surfaces, and the brushes are suitable for working with brick walls.

For a qualitative result, adhere to the technology of applying the mixture. On the wall, the soil is applied in several layers. Re-processing occurs after the final drying of the first layer. The material is applied evenly over the entire surface of the wall.

The walls are primed at temperatures above 5 degrees Celsius. Otherwise, the composition will not be able to soak the surface.

  Walls with a large number of delaminations need to be carefully cleaned

How to work with a primer for putty

Practice shows that perfectly smooth walls without plastering or puttying do not exist. Any layer of primer mixes only repeats the contours and does not contribute to leveling. Starting to putty, adhere to several rules. The wall should dry after treatment with mixtures and not have dust and grease stains on the surface.

If the surface is porous, then to prevent excessive absorption of putty, it is covered with a deep penetration primer.

If you want to align the walls with a large difference, then apply several layers of putty. In this case, make sure that each layer is not thicker than 10-15 millimeters and is applied only after the previous one dries. Drying each layer takes 10 hours. The exact drying time depends on the room temperature and the type of substrate.

  As the primer evaporates, the respiratory tract is protected by a respirator

How to wash surfaces from getting a primer?

When working with mixtures, especially when using a spray gun, contamination of other surfaces becomes inevitable. For washing, an abrasive brush and cleaning products such as “Mr. Muscle” are suitable. If the solution got on the tile, then wiping it becomes problematic. The use of solvents such as acetone, gasoline and ethyl acetate will help here. But they should be used on those surfaces where they can not harm the coating.

Is it necessary to prime the walls - expert opinion:

An important factor is time. The longer the primer stays on the foreign surface, the deeper it is absorbed. Therefore, they begin to clean the surface, without waiting for the mixture to set.

In contact with

Experts say that priming the walls before puttying is an obligatory stage of preparatory work, although this work may seem like a waste of time and money to an ignorant person. In order to cast aside doubts, you need to understand why this coating is needed, what functions it performs and whether it is necessary to prime before puttying.

  Why do we need a primer before puttying?

Coating the wall with a primer pursues several goals at the same time. This layer:

1. Provides bond strength for putty and wall
2. Saves material consumption
3. Improves the quality of the result.
4. Ensures durability of the putty layer

The mixtures used for priming the walls before putty contain cementitious components, fine sand. This creates the necessary roughness on a smooth wall, provides reliable bonding of materials. Otherwise, the applied layer may be poorly fixed, which will cause its cracking, shedding. Putting putty directly on the wall will require a greater consumption of material, since the mixture will initially be absorbed, filling microscopic voids in plaster, wood, concrete, and other materials. Primer eliminates this process.

Everyone who has tried to learn how to properly putty walls () knows that the most difficult thing in this work is to create a uniform layer. The primer evens the surface of the wall, which greatly simplifies the task. Putty is better distributed on the surface, providing a high-quality result. This material, absorbed into the plaster, the wall, protects it from moisture. Therefore, the finish retains its integrity longer.

  How to prime walls before puttying

There are several types of primers, now you will find out which primer to use before puttying. Purpose, material properties depend on the basis of the mixture. She may be:

• Mineral
• Acrylic
• Alkyd
• Polystyrene, etc.

In roughing, which is required to level the walls of concrete, gas silicate blocks, bricks, plastered surfaces, a primer created on a mineral basis is used. The addition of cement to such mixtures allows them to increase adhesion, to ensure reliable adhesion.

Acrylic primers are universal. They are suitable for processing any surface:

• Plastered
• Cement
• Concrete
• Drywall
• Stained

Acrylic copolymer base for perfect grip. An additional advantage of the material is its quick drying, which reduces the time for finishing work.

Alkyd based primers also have universal properties. These mixtures are used both in rough and secondary processing. Alkyd primers contain rust inhibiting ingredients, which is why these mixtures are great for treating metal surfaces.

Polystyrene primers can be used for plastered walls. But due to their high toxicity, such mixtures are not used indoors.

There are special types of primers in which components are added that prevent mold from appearing, preventing damage to the ceiling from being exposed to nicotine, etc.

  How to primer walls before putty

Putty is the final step in preparing the walls for final finishing. These materials are applied in a thin layer. Therefore, if there are deep irregularities on the surfaces, differences, initially performed. Only then is a primer applied. The work will require:

• Primer
• Capacity
• Brush
• Roller
• Respirator

If there are contaminants on the surface, they must be removed before priming. Then the walls need to be moistened. To do this, the surface is treated with a sponge dipped in water. The primer can be applied to the wall with a brush. But the roller allows you to significantly speed up the process. The mixture with its help is distributed more evenly. A brush is used to process corners and other hard-to-reach spots. The resulting primer should be thin. Accumulation of material in separate places must not be allowed. When smudges appear, they must be removed immediately. The applied primer of the walls must be completely dry before the putty of the walls. Drying time is indicated on the packaging with the product. It can depend not only on the composition, but also on air temperature, humidity.

Repair in your own home is a long and troublesome process. Those who decide to do it with their own hands will first of all encounter problems choosing the necessary building materials. For example, a primer. It seems to be not the most important material, but modern repair work without this fluid is not carried out. And the question is whether it is necessary to prime the walls before puttying or another type of finish, and is relevant today. Many people think that this process is an extra cost, because literally twenty years ago no one knew about this solution.

To begin with, let's figure out why a primer is needed.

1. With its help, the adhesive properties of the treated surface are increased.
2. Hardening of the top layer of the wall occurs. And, no matter, the wall is brick, wooden, made of blocks, plastered or concrete.
3. Grease and oil stains, areas of paint that are difficult to remove, close with a film. That is, even on such a wall you can putty.
4. Some species have antiseptic properties. This is especially important in wet rooms.
5. In addition, the applied primer reduces putty costs.

From the point of view of economy, the last point is interesting. It turns out that on the primed surface leaves less leveling material. And since the primer is several times cheaper than putty, the savings are obvious. But other items on the list are equally important. Especially when it comes to old walls, fragile with large defects. Nobody will think about whether it is necessary to prime the walls before puttying.

Variety of choices

Primer manufacturers are trying to approach the issue of hardening walls from all sides. Therefore, there are so many different types on the market. Some of them are universal, some are used in specific situations and for specific surfaces. What do manufacturers offer today?

• Acrylic primers - this category of universal solutions. They can be used to process any materials: from brick to metal, and even more so, drywall primer before puttying.
• Phenolic - only metal and wood can be processed. Although experts claim that it can also be applied to drywall, but not to putty.
• Alkyd - used when working with wood.
• Polyvinyl acetate - is used to treat any surfaces, but only if they are painted on the basis of the same material.
• All other types, and this is glyptal, perchlorovinyl, polystyrene, can be used only for outdoor work.

This is why acrylic primers are so popular. It can be applied on drywall before and after putty. So, now it becomes clear how to prime drywall before puttying.

Why do I need to prime drywall

Should drywall be primed before puttying? This question has a double attitude for many. But those who are familiar with the GCR firsthand know how things are going with its finish. Especially when the drywall plane is prepared for wallpapering or facing with ceramic tiles.

The thing is that the cardboard surface is very flat and smooth, so that the adhesive compounds are not attached to it one hundred percent. But that is not all. When fastening GKL sheets to a metal frame, a slight warpage of the sheet itself occurs. In places where self-tapping screws are installed, the plane is pressed in, and, conversely, where there is no fastener, it becomes convex.

And such a plane must be aligned. This is where putty mixtures are used. And so that they are well attached to the cardboard surface, and a primer solution is used. In addition, primers serve as antiseptics. So after their application, neither mold nor fungi will appear.

Possible primer errors

Let us turn to the experience of professionals. What mistakes can beginners make and why can't they just be made?

We hope that your doubts as to whether the walls should be primed before puttying have been dispelled. The most important thing is to understand that this cheap material, which can be easily applied with your own hands, works wonders. And it doesn’t matter whether you have an old wall or just been built. In any case, the primer must be used.

We look forward to your comments on this article. It would be interesting to know your opinion. Maybe someone will add information, talk about their personal experiences.

Everyone who decides to do their own finishing work in the house is faced with the question, what is first: primer or putty? The answer is unequivocal - a primer. Whatever material the base surface has — metal, concrete, wood, plaster — all future coatings on it should hold firmly. To do this, a primer is used that penetrates deep into the base and makes adhesion to the next coating better.

The primer has adhesion and fixing properties, so it prevents damage to the base coat. In addition, the primer layer promotes uniform application and absorption of paint, plaster, glue, putty and so on. As a result, the quality of the final finish becomes much higher. Note! Before using the primer, it is necessary to prepare the surface.

Naturally, you don’t have to bother with a primer, but in this case the repair quality will be much lower, and in the future the plaster will peel off, the wallpaper will lag behind, and cracks and spots will appear on the surface due to moisture. Therefore, the application of a primer is recommended, because it gives an additional guarantee of quality.

For processing various surfaces, various primers are also used. It is necessary to take into account the type of coating, the conditions and features of the room, and the method of subsequent finishing. They can be divided into two groups: primers for primary surface treatment and compositions for improving adhesion between materials. They are produced on alkyd, mineral, acrylic and other bases.

Puttying

Even thick primers follow the contours of the surface. Therefore, to make it even and prepare for subsequent work, the surface is puttyed. The dried putty can be easily sanded, which makes it possible to achieve perfect surface evenness. All modern putty is a dry mixture that is seasoned with water or a ready-to-use paste-like mixture. They are divided into leveling and finishing.

Leveling is used for "rough", preliminary leveling the surface. They are applied in a layer of 0.5-2.5 millimeters at a time. The solution is made plastic so that after drying it does not turn out shrinkage and spreading. Finishing putty is necessary to eliminate minor defects, scratches, cracks. It is usually applied in a layer no thicker than one millimeter. Very thin layers are called superfinishing.

They are superimposed with a thickness of 0.1-0.2 millimeters in several layers with intermediate drying. Care must be taken to ensure that the total thickness of the layers does not exceed the maximum permissible thickness, otherwise the surface may crack. Note! The maximum permissible thickness for each mixture is different, and it is indicated on the package.

Calculate and save

Priming and puttying material is not the most expensive for finishing work, but still it is worthwhile to calculate in advance which class of the mixture is needed and how much it will be needed for the work. Such a simple calculation will protect against the additional costs of an already not cheap repair. It is necessary to think over the whole course of work, draw up a plan and follow it. This will avoid problems, such as the applied primer after putty. Points to consider:

• Calculate the area of \u200b\u200bthe treated surface;
• Based on the area, calculate the amount of primer and putty needed (for this you need to read the instructions on the package where the flow rate is indicated);
• Be sure to take into account the type of surface;
• Take into account the degree of necessary leveling of the surface;
• Buy mixtures with a small margin.

Important! Each material has its own degree of absorption, therefore, when calculating this fact must be taken into account.

Making a plan taking into account these factors, you can maximize secure and trouble-free operation. For a more accurate calculation, it is better to consult a professional or a person who has experience in such work.
