It is necessary to putty the walls before wallpapering. Which putty is better to choose?

Does putty have an expiration date?

I want to use dry putty.

It was purchased in the summer. But I was already lying down at a temperature of -2 - -4. Is it good?

• The choice of putty depends on the condition of the walls. If the slabs have not been stripped and the walls are relatively smooth, then you can immediately use “finishing” putty. It is of the smallest fraction and lies flat. If you already have putty (it hasn’t spoiled, it’s even better in the cold, as long as the humidity isn’t too high), then it’s better to take the same brand. I like Uniflot the most. He's strong even plasterboard walls- it doesn’t crack, but it’s a bit pricey. You can take “Fügenfüller”, “Vetonit”, or ready-made oil-glue in buckets. If money is really tight, take Hercules, but it’s a bit soft. Although it will go under wallpaper. The main thing is to choose a putty based on GYPSUM - it is white.
• it’s suitable, they made Vetonit kr for us, first they primed it, then they puttyed it, sanded it, primed it, then glued it - in general it’s a nightmare
• For dry putty, you can use Vetanit KR for the first layer of putty and LR for the second. If the putty was lying in a damp room, it is better not to use it, or if used, dilute it with a primer.
• If your putty is not damp, then no problem. The most important thing is to look at the instructions for use (area of ​​application (wet or dry rooms), thickness of the application layer, drying time, etc.), believe me, the result, as a rule, directly depends on how much we adhere to the manufacturer’s recommendations! Good luck!!!
• If you are going to use wallpaper, then ABS will do, but be sure to prime the surface before puttying...

What happens to dry putty after the shelf life expires? Why can’t I use an expired one (see ext.)?

I bought it a long time ago, but the repairs were delayed. And it so happened that the shelf life expired several months ago. Is it possible to putty with this mixture or is it better to throw it away? Professionals, what do you recommend?

Putty for windows

Puttying windows is a very frequently discussed and very painful problem for many builders. It is worth saying that even if you have basic knowledge of putty, then with a 90% probability, your knowledge will not be enough to putty windows.

So, let's start with the fact that you need to determine exactly what type of surface the putty will be applied to.

That is, window putty is unique for each of the existing materials. This uniqueness manifests itself more in the types of materials used than in the application technique. We choose the same window putty.

Many people write that the Trioza putty copes with the task very well. One person responded to a thread about window putty on a well-known forum. He said that after carefully removing debris and other contaminants, he applied a light, even coat of putty.

At the moment, the putty is already more than 3 years old, and it is still like new. So, a lot also depends on the brand of putty.

No one will argue that the most good brands putties, not those that are advertised, but those that are really time-tested. Because advertising will always remain advertising, and nothing more.

It will only show one side of the coin. To make a choice, you should turn to really knowledgeable people, which, so to speak, “ate the dog” in this matter.

Also very interesting option For general putty, and not only for windows, is high-temperature putty. As a rule, it is simply ideal for exterior finishing premises. It, as the name suggests, can withstand very high temperatures.

It can work in very harsh weather conditions, from -35, minimum -40 degrees, to +200, maximum +280 degrees Celsius. Very good temperature range.

Also, gypsum plaster putty comes under big questions. As a rule, this applies to walls and ceilings. Many experts in this matter advise to putty the gypsum board with Vetonit LR+ putty.

In addition, Petrominsk is a very good option. But this, of course, is a matter of taste.

But, nevertheless, putty, no matter what it is, and no matter what it is intended for, should be applied, at a minimum, by a knowledgeable person.

Most problems associated with putty are a consequence of the “curvature of the hands” of the layer himself. But also, you shouldn’t lose sight of the putty itself. Yes, very important nuance is the shelf life of the putty, since after its expiration date, it is more likely to either lie poorly or not completely dissolve.

And both will have a very detrimental effect on the final result. So, the shelf life of putty is one of the most important, although not the main, parameters that need to be checked when purchasing putty. In addition, it is worth buying putty that will be suitable specifically for your type of work.

Of course, it doesn’t have to be just one brand. Nowadays, you can find up to twenty types of different putties to perform the same job.

Expired putty expiration date. can I use it?

Putty mixtures have a shelf life of 6-12 months. After this period, the putty will lose its properties - it sets very quickly. But if you want to cover up a hole or install a box for sockets, you can still use it, but if you putty surfaces, I don’t recommend it.
Moreover, your putty is 2 years old. And the official manufacturer reports: Storage: Caparol-Akkordspachtel fein. mittel and SF

Gypsum putty is an excellent assistant for finishing concrete, brick, plaster and plastered walls in dry rooms. Experienced people use it for rough finishing. This type putty material is popular both among craftsmen and those who do repairs themselves.

Why are walls puttyed?

Any wall, be it gypsum blocks or concrete structure, uneven. Even if we are talking about a new multi-storey building, there are still small slopes and differences. This type of putty is used to smooth out these imperfections.

And in cases where the base also has cracks or chips, puttying is definitely indispensable. The gypsum composition is also used for sealing joints and leveling the ceiling. The substance adheres well to the base.

wall putty is the key to long lasting repairs

Whatever company produces gypsum putty, the composition is practically the same. The basis is finely ground gypsum with the addition of components that help penetrate the treated surface. The composition of such mixtures is environmentally friendly, which allows the use of gypsum putty in almost any room.

Professionals point out that this type mixtures for treating walls and ceilings have a wide range of advantages. Let's highlight a list of the main advantages:

• Plasticity of the material - the composition is not subject to cracking after certain periods of time;
• Ease of operation;
• The ability to regulate moisture absorption by walls;
• Durability;
• Absence of components harmful to health;
• High level of adhesion;
• Wide scope of application. Possible finishing of walls, ceilings and other surfaces

One of the disadvantages gypsum putty is that she is afraid high humidity. Therefore, it is better not to use the composition in rooms with constant high humidity. And in places with periodically rising humidity (kitchen), install a good exhaust system.

Using putty, even walls with differences of 1-2 centimeters are leveled

How does starting putty differ from finishing putty?

Which putty is suitable for sealing seams and cracks? This question can be answered by studying in detail the three main types finishing materials. The putty is divided into:

starting;

finishing;

universal.

Starter putty is suitable for finishing walls and ceilings. With its help, cracks and gaps are sealed, differences of a centimeter or two are leveled out.

This mixture is applied evenly over the surface in a layer of up to ten to fifteen millimeters. If the surface has significant differences, then the use of putty is impractical for the reason that too thick a layer will easily fall off the ceiling or wall. Therefore, to handle large differences, it is recommended to use plaster or cladding with gypsum board sheets.

After leveling with the finishing compound, the walls are ready for painting

Finishing putty is used to level the surface in a single layer and make it even and white.

The final type of wall putty is used for further painting. The composition of the finishing mixtures is visually different from the starting mixture in that the material is less grainy and whiter. If after applying the starting material the walls have a gray tint, then when covering the ceiling or walls with finishing putty, they acquire a milky white tint.

The universal putty is called “start-finish”. It is used when leveling walls and ceilings under wallpaper. The universal composition allows you to save on the purchase of two types of materials without compromising the quality of the final coating.

Note that gypsum material is easy to work with. If you follow the mixing and application technologies, even a person without experience can cope with the rough finishing of walls.

The company Starateli produces mixtures in bags of various sizes

Which companies should you pay attention to when choosing a mixture?

When it comes to purchasing building materials to start work, here key factor becomes the choice of the manufacturer. Modern market filled with both established brands and newcomers.

And when choosing cheap goods from such companies, it is important that the quality is no worse than that of popular brands like Knauf, Ceresit, Sniezka, Perfekta, Bergauf. Among the Russian representatives, we would like to highlight the already well-known companies Starateli and Axton. They will be discussed further.

When choosing a product, pay attention to reviews about the manufacturer

If we talk about Axton putty, it is used as universal material for rough finishing of walls.

The composition includes fine-grained gypsum with the addition of components for high adhesion and plasticity. The viability of this solution after mixing is one hour, so you should not try to mix the entire bag at once - such a volume of material is unlikely to be applied to the wall in just an hour. Drying time at room temperature is 20-22 hours.

Finishing putty Prospectors in a bag 12 kilograms

The Prospector company produces putty of various compositions.

The most popular are polymer putty and gypsum. They are rightly called the leaders of the domestic construction market. Prospector gypsum putty consists of fine-grained gypsum with adhesive and polymer additives.

Starateli putty is available in bags of different volumes, which allows you to accurately select the required amount of the mixture.

The consumption of material with a thickness of 1 mm for each square of surface does not exceed one kilogram. Prospector putty should be used within an hour when mixed. The time for setting and hardening of the composition on the surface is 5-7 hours after application.

Remember that there are also counterfeit goods on the market. Often, fakes contain poor quality gypsum, which cracks after being applied to the surface. Such materials may also contain harmful substances not listed on the packaging.

Therefore, try to carefully inspect the goods and demand quality certificates. Please note that gypsum mixtures have a short shelf life of 6 months. After the expiration date, the mixture loses some beneficial properties, which will definitely affect the final result.

Gypsum putty is used for finishing different surfaces. You can do the puttying yourself without inviting specialists.

High-quality putty has a fine-grained structure, thanks to this it is possible to fill up unevenness from 1 to 1.5 mm. If the curvature is greater, you must first plaster the surface.

Characteristics of putty

The Knauf company produces the highest quality gypsum putty, which contains polymer additives and fillers and is capable of drying in a short time, forming a durable and smooth film on the surface. Advantages of gypsum putty:

• the use of such a mixture prevents the formation of cracks on the treated surface;
• thanks to vapor permeability, it helps create a good microclimate;
• easy to use;
• quite hard, durable and has a long service life;
• goes well with other materials;
• low consumption, which is economically beneficial;
• acceptable cost.

Like anyone else building material, Knauf putty has its disadvantages:

• sets quickly (can be considered a plus);
• difficult to grind;
• not suitable for finishing wet rooms; in this case, acrylic putty is more suitable.

The maximum layer of application of Knauf putty is no more than 3 mm.

Otherwise, the surface will be uneven with sagging and grooves. Gypsum putty is intended for applying a thin layer to the surface to be finished. She creates good foundation for gluing wallpaper, because the thickness of the largest fraction can be only 0.15 mm.

Knauf took good care to ensure that its gypsum putty dries quickly. You cannot prepare a large amount of the mixture at once, otherwise after 30 minutes the entire mass will begin to harden and become unsuitable for finishing.

Fast setting occurs due to the gypsum. It should be remembered that the container in which the solution is mixed and the tools for work must be clean. Dirt on the walls and tools speeds up the hardening time of the mixture by almost 2 times.

The shelf life of Knauf dry mixture is 6 months, so you should not buy it for future use.

Preparation of working solution

Before you start working with putty, you need to check the expiration date. Expired material should not be used. The finished mixture, depending on how it was mixed, may have different properties.

The first rule when mixing: pour the powder into the water slowly, spreading it over the surface of the water.

It is best to do this with your hands rather than with a trowel. The mixture must be added until the putty level is slightly higher than the water level. Then give the mixture 2 - 3 minutes to swell.

Stirring is done manually, without using a mixer. The mixture may seem runny, but do not add dry powder. After a minute or two, everything will work itself out and find the desired consistency.

Under no circumstances should the residue from the spatula be added to the bucket with the working mixture. This leads to a reduction in the working time of the solution and the formation of lumps.

Preparing for work

For puttying you will need the following tools:

• rule;
• metal spatula;
• container for mixing the mixture;
• water spray;
• spatula or trowel.

Before purchasing Knauf material, you should decide on the type of putty.

Depending on the stage of the work being performed, it can be universal, starting or finishing. This is usually indicated on the packaging. Need to study technical specifications material.

To prepare the surface for work, it is necessary to remove old wallpaper, paint, clean the walls from dirt, greasy and rust spots. If there is mold, remove it by special means, which contain antiseptics.

The walls must be treated with a primer, which is selected depending on the type of base. It is recommended to apply the primer in 1 - 2 layers.

Then you should dilute the putty and get to work. It is important not to forget to periodically stir the composition while working. Sometimes you can add a little water so that the mixture retains its plasticity and does not harden for some time.

Do not allow the composition to come into contact with eyes or skin. If this happens, you need to rinse the affected area generously. warm water. It is recommended to carry out the work in special clothing; it is also necessary to use skin protection products.

Surface application

Puttying is done using spatulas different sizes. A small portion of the Knauf mixture is applied to a larger spatula, then rubbed over the surface in an even layer.

The applied layer should dry within 1 - 2 days. Next, to level the surface, sanding is performed using fine-grained sandpaper. The final stage is the application of decorative facing material(plastering, painting, whitewashing, wallpaper, etc.).

In order to efficiently prepare the surface for any type of finishing works, you need to level it.

This can be achieved with proper puttying and priming. In this case, it is important to skillfully use the tools and follow the recommendations for implementation.

Putty "Vetonit" Vetonit LR+ (25kg) Finishing putty weber.vetonit on a polymer binder for finishing walls and ceilings in dry rooms

Vetonit LR+ putty for leveling walls and ceilings inside dry rooms before: wallpapering; painting.

Characteristics

Description

Preparing the base
The base must be solid, clean, free from dust and dirt. Substances that weaken adhesion such as grease, dust, etc. must be removed. The base must be dry. Excess moisture in the structure can cause yellowing of the leveled surface. Windows and other untreated surfaces must be carefully protected.

Preparation of Vetonit LR+ mixture
Fill the container with approx. 9.0 liters clean water and fill in 25 kg (bag) of the weber.vetonit LR + mixture, and the mixture must be added to the water, and not vice versa. Recommended water temperature is 20°C. Mixing is done powerful drill with the nozzle for 3-5 minutes. To better dissolve the binder, the mixture is allowed to stand for 10 minutes. After light re-stirring, the mixture is ready for use. The mortar mixture is suitable for use within 24 hours from the moment of mixing with water. When storing the finished mixture in a closed container, the putty is suitable for use for 2 days. Temperature mortar mixture must be at least +10°C.

Application
Vetonit LR+ mortar mixture is applied by mechanized spraying or manually and leveled using a two-handed steel spatula. For partial leveling, use a smaller steel spatula 30cm wide. When leveling in several layers, it is necessary to apply each subsequent layer on the completely dry previous one. The dried surface of the putty must be treated sanding paper and remove dust before applying the next layer. After sanding, the leveled and dried surface can be painted or wallpapered according to the instructions of the manufacturer of these materials, or left uncovered when creating a rough “fur coat” surface using a mechanized spraying method. To increase the wear resistance of the material and improve adhesion, you can replace 10% of the mixing water with a primer.

Drying time of Vetonit LR+ putty
The drying time of one layer of Vetonit LR+ of the recommended thickness at +10 °C is approximately 2 days; at +20 °C approx. 1 day, with good ventilation. Drying time depends on layer thickness, ventilation and temperature.

Does the putty have an expiration date?

• There is no expiration date. If it is dry, dilute it with a little water, mix well and use as directed.
• If it hasn't dried out, it's good...
• The main thing is that it is stored correctly. as they say: I keep my loyalty to my own bride in a cool, dry place!
• If it is ready, it may dry out or even go rotten. If it is dry, as is almost always the case now, then if the bag has not gotten wet and it has not become hard, then you can use it.
• Look at the packaging, each has its own expiration date.
• yes about 10 years

Construction mixtures (putties, etc.) stood on the loggia for 4 years. Can I use them or throw them away?

• In principle it is possible. But gypsum mixtures can harden quickly /5-10 minutes/

It is necessary to check. Putties /loose/ if they have not absorbed moisture, then they are suitable.

Plasters on cement based, if not turned to stone, use it.

• Hardly
• If you haven't become a monolith, try it
• Dry mixtures, if they remain “dry”, are quite suitable. ready-made mixtures If it's frozen, throw it away.
• Well, if they didn’t get wet and didn’t turn into stone, then you can
• To be thrown away. They became like alabaster.
• putty, if suitable without lumps. Throw away the bag in any case. Sift the cement. Grout will do. Source: personal experience
• Throw it away, the expiration date has expired, when mixing such putty or gypsum plaster they will harden like plaster.
• It’s possible if you don’t grab it
• Additives that slow down the setting of gypsum and alabaster could become unusable. Therefore, it is necessary to check the hardening time. If it meets the stated characteristics, you can work. If not, then you can slow down the drying by adding flour or brewed starch to the mixture. But this is at random...
• Can be used!!! but for example, it is not advisable to seal any holes, for unimportant ones (in the toilet at the dacha) it is not advisable, the frost does not spare anything
• each bag should have an expiration date written on it, for putty mixtures it is somewhere around 6-12 months, after this period it will lose its properties, I checked it myself, it sets very quickly, so you can still use it to cover up a hole or install a box for sockets, But if you produce surfaces, don’t even try, you’ll just ruin the tool!
• Throw it away. There is no need to risk wasting effort under the condition that the result will not be guaranteed, even if everything falls on the walls, that is, there is a risk that the service life will be short. For example, Rotbant plaster has a shelf life of 6 months.

• In general, bulk products have a shelf life of two years; then it is practically impossible to work with them.

Knauf putty » construction from A to Z

2.3. If unsatisfactory results of periodic tests are obtained, the manufacturer checks each batch until satisfactory test results are obtained in a row of at least three batches.

3. TEST METHODS

3.1. Sampling - according to GOST 9980.2.

Before testing, samples of putty paste in a tightly closed container are brought to a temperature of (20 ± 2) °C.

IN winter time Before sampling, it is allowed to heat the putty paste in a tightly closed container at a temperature not exceeding 60 °C.

3.2. Preparing samples for testing

The elasticity of the putty coating during bending is determined on plates made of black tin according to GOST 13345 with a thickness of 0.25 - 0.32 mm and a size of 70 "170 mm.

Moisture absorption is determined on aluminum plates according to GOST 21631 or GOST 13726 with a size of 50" 50 mm and a thickness of 0.2 - 0.3 mm.

The remaining indicators are determined on plates made of steel grades 08kp or 08ps according to GOST 16523, 70" 150 mm in size and 0.8 - 0.9 mm thick.

To apply putties, unprimed plates prepared in accordance with GOST 8832, section. 3.

The conditional and mass fraction is determined in the putty paste. To determine other indicators, the putty paste mixed with the hardener, as indicated in paragraph 1.2.2, is kept for 15 - 20 minutes before applying to the plates.

The putty is applied to the prepared plates with a spatula using a special device.

The device for applying putty (Fig. 1 - 4) consists of a steel plate to which four brackets with thrust wings are attached, a pressing steel frame and stencils of various thicknesses. The surfaces of the plate and frame must be sanded.

The prepared plate is tightly clamped between the plate and the stencil using a frame and thrust wings, and putty is applied to it with a metal spatula to the edges of the stencil, removing the excess. The size of the cutout in the stencil is 50" 130 mm.

To apply EP-0010 and EP-0020 putties, a 0.5 mm thick stencil is used.

The thickness of the putty coating after drying should be no more than 350 microns.

The putties are dried at the temperature and for the time specified in the table. 1.

Putty application device

Before hot drying, the plates with putty applied are kept at a temperature of (20 ± 2) °C for 1 hour.

After hot drying, the plates with putty applied are kept at a temperature of (20 ± 2) °C for 3 hours.

In case of disagreement in the evaluation of putties EP-0010 and EP-0020 according to indicators 1, 5, 6 and 7 of table. 1, the plates are dried at a temperature of (20 ± 2) °C for 24 hours.

3.3. Appearance The putty coating is determined after it has dried visually, by inspecting the surface of the putty coating before and after grinding in diffuse daylight.

Grinding (when the plates are wetted with water) is carried out using sandpaper with grit No. 4 - 6 according to GOST 6456 or GOST 10054.

3.4. The conditional viscosity of the putty paste is determined according to GOST 8420. Before determination, the putty paste is diluted with toluene according to GOST 9880 or GOST 14710 in the ratio by weight: 1 part solvent and 4 parts putty paste.

3.5. The mass fraction of non-volatile substances is determined according to GOST 17537.

A sample weighing (2.0 ± 0.2) g is heated in an oven at a temperature of (120 ± 2) °C. The first weighing is carried out after 3 hours of drying. Subsequent weighings are carried out every 30 minutes until a constant weight is achieved.

The mass fraction of non-volatile substances under an infrared lamp at a temperature of (120 ± 2) °C is allowed.

In case of disagreement in the assessment of the mass fraction of non-volatile substances, the determination carried out in an oven is taken as the final result.

3.6. Determination of bending elasticity

The elasticity of the putty coating during bending is determined using a device for determining the elasticity of putties (Fig. 5).

The device consists of metal plate, to which half-cylinders with a diameter of 100 and 50 mm are attached, a movable frame with a pressure roller for pressing the plate to a cylindrical surface, a fastening screw and wooden stand.

The plate is secured at one end to the device using a fastening screw and, when lowering the frame to a horizontal position, it is pressed with a roller to a cylindrical surface. The test is carried out on three samples.

The putty is considered to comply with this standard if, when bent along a half-cylinder with a diameter of 50 mm, no cracks are formed on its surface that are visible without magnifying devices.

Cracks at a distance of up to 15 mm from the edges of the putty coating are not taken into account.

3.7. Sandability

After drying, the surface of the putty is sanded with waterproof sandpaper with grit No. 4 - 6 according to GOST 10054, GOST 6456 or GOST 5009. Grinding is carried out evenly over the entire surface, wetting it with water. After sanding, the surface of the putty is washed with water and wiped dry. soft cloth.

Device for determining the elasticity of putties when bending

The putty complies with this standard if, when sanded for 15 minutes, it does not become wet and a smooth matte surface is formed.

3.8. Determining the shelf life of putties

3.8.1. The shelf life of putties when applied by pneumatic spraying is determined according to GOST 27271.

For testing, take (150.0 ± 0.2) g of EP-0010 putty paste, add (12.75 ± 0.2) g of hardener No. 1 or (4.5 ± 0.2) g DEET, and (150 .0 ± 0.2) g of EP-0020 putty paste - (12.75 ± 0.2) g of hardener No. 1 and mix thoroughly until a homogeneous mass is obtained. Then the mass is diluted to a viscosity of 18 - 20 s using a viscometer type VZ-246 (or VZ-4) with a nozzle diameter of 4 mm with one of the solvents specified in clause 1.2.3, and kept in a tightly closed container at a temperature (20 ± 2 ) °C for 6 hours, after which it is thoroughly mixed and the viscosity of the putty is determined again.

The putty is considered to comply with this standard if, after the specified time, the viscosity does not exceed 40 s.

3.8.2. To determine the shelf life of putties when applying them with a spatula, add (8.5 ± 0.2) g of hardener No. 1 or (3.0 ± 0.2) g to (100.0 ± 0.2) g of EP-0010 putty paste DEET, and to (100.0 ± 0.2) g of EP-0020 putty paste add (8.5 ± 0.2) g of hardener No. 1, mix thoroughly until a homogeneous mass is obtained and kept in a tightly closed container at a temperature (20 ± 2) °C for 1.5 hours.

The putty is considered to comply with this standard if, after the specified time, it is easily applied with a spatula without curling under it.

3.9. Determination of moisture absorption

The test is carried out in accordance with GOST 21513. To determine moisture absorption, EP-0020 putty is applied with a spatula over a stencil and dried at a temperature of 65 - 70 ° C for 7 hours. The thickness of the dried coating should be no more than 350 microns.

The base must be clean, hard and dust-free. Substances that weaken adhesion such as grease, dust, etc. must be removed. Windows and other untreated surfaces must be carefully protected.

Attention! The base must be dry; leaks and excessive moisture content in the structure are not allowed, as this can cause discoloration of the leveled surface.

Mixing

A bag of dry mixture (25 kg) is mixed with 8–9 liters of clean water. Mixing is done with a powerful drill with an attachment for 3-5 minutes. To better dissolve the binder, the mixture is allowed to stand for about 10 minutes. After light re-stirring, the mixture is ready for use. The mortar mixture is suitable for use within approximately 2 days from the moment of mixing with water. Unused mortar mixture should not be left in the mixing container, hoses, etc. for more than 2 days (for example, on weekends).

Attention! Do not pour the mortar mixture down the drain to avoid clogging the pipes.

Getting the job done

The mortar mixture is applied mechanically by spraying or manually using a steel spatula. For complete leveling, use a steel trowel 80 cm wide; for partial leveling, a smaller steel trowel 30 cm wide is used. Excess mortar mixture is removed and used again. After spraying the putty, the ceiling can be left without further processing. If leveling is carried out in several layers, each time you need to make sure that the previous layer is completely dry (within 1 day). The dried surface is sanded with thin sandpaper after each layer.

Cleaning the instrument

Working tools and equipment are washed with water immediately after finishing work.

Final surface treatment and additional recommendations

The leveled and dried surface can be painted or wallpapered according to the instructions of the wallpaper or paint manufacturer.

When dirty spots the surface can be carefully wiped with a damp sponge or piece of cloth. If the stains do not come off, the surface can be re-coated with putty.

Useful tips

To increase adhesion to painted surfaces and to improve the wear resistance of the material, you can replace 10% of the mixing water with Vetonit Dispersion (approx. 0.8–0.9 l Dispersion/25 kg of dry mixture). Before starting alignment work, make sure that the clutch is old paint good with the base.

Packaging and storage

Vetonit LR Plus putty is supplied in bags of 25 and 5 kg. Shelf life in a dry place in closed containers is approx. 12 months from date of manufacture.

Hello, dear visitors! This time we will get acquainted with a whole phenomenon in the world of finishing materials. The hero of the day today will be putty, whose name has long become a household name for craftsmen - Vetonit putty (weber.vetonit LR+).

Nowadays, construction stores offer dozens, if not hundreds, of different types of putties: gypsum, cement, polymer. But two brands stand apart; they are available always and everywhere, and have been producing them for decades. Yes, yes, the first one is Vetonit. What's the second one? If you're a decorator, you probably know the answer.
This is Sheetrock. There will definitely be a separate article about it too. This thing is very, very high quality. In order not to miss material about, subscribe to updates, the post will be very useful for everyone!

But for now we are talking about the product weber.vetonit LR+.

This is what is meant when they say “vetonite”. This is a finishing putty with a polymer binder. What does "finish" mean? And the fact is that after its application, wallpaper and/or painting, that is, finishing coatings, begin.

In other words, this mixture forms a high-quality coating, ready for painting and wallpapering. As for the binder. Any mortar consists of filler and binder. The filler is usually sand, limestone is what forms the bulk of the composition. And the binder holds the filler particles together and, naturally, ensures adhesion to the base surface. In this putty, the binder is a kind of polymer glue, and the filler is limestone.

Our hero is produced by Weber-Vetonit, part of the Saint-Gobain group. Packaged in paper bags 25 and 5 kg.

Basic properties

The purpose of this putty mixture is to level walls and ceilings in dry rooms before wallpapering and painting. It is used on all types smooth surfaces from mineral materials and plasterboard. Formally it has a white (in practice slightly grayish) color, as well as its own weak specific odor.

By the way, in our village (it’s called Ryazan, maybe you’ve heard of it) it costs around 650-700 rubles for 25 kg.

It should be remembered that it is not moisture resistant, and is not suitable as a base for laying tiles or as an adhesive for anything. For example, some people manage to glue ceiling plinths onto it. This cannot be done. Its structure is quite loose and fragile, which, however, does not affect its ability to hold wallpaper on itself, but can play a fatal role when trying, for example, to seal the joints of HA sheets with it.

Water consumption is 9 liters per 25 kg bag. The mixture is stirred using a drill or a hammer drill with a mixer until it becomes sour cream, after which it is allowed to brew for 10 minutes. This time is needed for better dissolution of the binder. It is noticed that after these 10 minutes the mixture thickens a little. Then it is mixed again.

Again, a separate article will be published about the technique of puttying walls and ceilings, the topic is very important, so subscribing to updates is a sacred thing!)) The article will contain a couple of my know-how, and I will just use Vetonit. Now is the time to find out what are the secrets of his popularity?

The main advantages of weber.vetonit LR+

I counted three of them:

1. Ease of application with almost complete absence of layer differences. If you wish and have the proper skill, you can putty the surface under the wallpaper so that sanding is not required at all.
2. If necessary, the putty can be sanded very easily due to its somewhat loose nature. And this is very important. For example, gypsum (universal putty from Knauf) is incredibly difficult to sand. When I tried Vetonit for the first time after it, I was amazed - no effort.
3. Surprisingly long lifespan. If you mix too much putty and don’t have time to use it all, just cover the container with a lid. The next day it will be waiting for you in the same condition in which you left it. It has been verified that for 2-3 days she calmly waits in the wings in a bucket, ready for work. You just need to stir it one more time.

Of course, the hero of the article also has a drawback. This is a lack of moisture resistance.

Let's say we are wallpapering. We glued the strip, when suddenly we noticed a crease or a bubble that simply couldn’t be smoothed out. Needs to be removed and re-glued. So, there is some probability that the strip will be partially removed along with the putty. To be honest, this has never happened to me before, because I carefully prime the surface before and after puttingty, plus I apply it in a certain way so that it lays more tightly. But such cases are known. But I don’t know of any other shortcomings.

I just can’t recommend using it for painting. Still, its fraction is too large for this, and visually the surface turns out to be rougher than when using Sheetrock. But I am a sophisticated user; for you, such a surface will most likely be more than acceptable. Once I had to paint the ceiling on the loggia using Vetonit (there was no choice), I carefully sanded it and covered it with two layers of white paint. I couldn't see any defects from the floor, not even the slightest. This is the ceiling:

Usually it is enough to apply the putty in two layers. The first one slightly trims the surface, the second one is finishing. Moreover, the second layer is applied only when the first is completely dry. If applied minimally, drying occurs in 3-4 hours. A layer 5 mm thick will dry for at least a day.

Conclusion

Vetonit putty is definitely popular for a reason. When preparing a surface for wallpapering, I use only this. If you mess up a little somewhere, use a sanding block once, and that’s it, it’s all in the bag. Before I had time to use up the bucket, I covered it, and the next day I came and “finished it off.” Just the thing for a finisher. I recommend it.
