How to use acrylic putty

Selection recommendations

To begin with, it is worth noting that there are water-dispersible acrylic putties designed for finishing concrete or wooden surfaces. The advantage of such formulations is their excellent water-repellent properties.

In addition, VDAK is more ideal for application to walls than to ceilings. This is due, first of all, to its less dense and dense structure, which somewhat complicates the ceiling finish.

For the purpose of leveling the ceiling space, it is advisable to choose a universal putty that has both the required consistency and optimal density and transparency.

To select the required density of the composition, it is necessary to carefully study the technical characteristics of the mixture. High density indicates a "tight" consistency, which is not always appropriate for certain substrates, such as walls. And a low density is not suitable for ceiling finishing works.

In order to choose the required volume, you need to accurately determine the goals of the repair. That is, if it is only supposed to renew the old putty layer, then it is up to the finishing compounds, the consumption of which will be on average 500 g / m 2 with a layer thickness of 1 mm, which is quite enough for cosmetic work.

In the case of serious defects in the plane, it is best to give preference to starting or universal mixtures with a flow rate equal to 1000-1500 g / m 2.

Application of the composition

Working with acrylic putty is a fairly simple task, even for a layman. As before starting any finishing work, it is necessary to prepare the plane for further application.

That is, to dismantle the outdated finish, clean the base and treat it with a primer. After the primer liquid has completely absorbed, it's time to proceed directly to the puttying.

Since most often the acrylic mixture can be found ready-made, after opening the container, the mass should be thoroughly mixed in order to use the precipitated components.

The preparation of a dry mixture involves mixing it with water in certain proportions indicated in the instructions.

The application of acrylic putty is carried out using a spatula and rules. After hardening, the putty needs light sanding.

Today, plastering work in indoor renovations has become an integral step towards creating smooth and attractive surfaces. Acrylic putty for interior work is a real treasure for both a qualified specialist and a home craftsman.

Combining a lot of advantages, the composition is gaining more and more consumer preferences every day and further and further displaces analogues in the popularity rank.

Acrylic putty, due to its many advantages, enjoys authority among builders. The features of this finishing material, as well as its application, will be discussed in this article.

Types of acrylic putty for indoor and outdoor use

The putty is presented in several varieties, depending on the scope of application:

1. Facade - putty for outdoor use has a specially developed composition that provides high strength, protective characteristics of the coating. The material is resistant to temperature extremes, climatic precipitation, mechanical damage, has thermal insulation properties and insulates the room from the outside.
2. The universal putty can be applied to different types of surfaces (walls, partitions, ceilings), various materials (brick, concrete, wood, metal, etc.).
3. Water-dispersive - putty is characterized by increased protection against moisture. The coating is durable, aesthetic, resistant to temperature changes.
4. Putty for interior work - the material is used for finishing rooms in an apartment, house. The composition is suitable for spaces with standard microclimate conditions without high levels of humidity and steam.

According to the form of release, the putty is divided into the following types:

1. Powdery - dry composition must be diluted with water before use. The variety is offered by manufacturers less often ready-made. The advantage of a powdery material is the ability to independently select the required consistency. The composition can be saved, because the cost of production is lower than the mass diluted with water.
2. Ready-made - it is offered in plastic buckets of 15-20 liters. The mass does not need to be kneaded, the material is ready for application, easy to use, optimal for beginners in the construction industry.

Separation of the putty according to the components:

1. Starting - used for the initial stage of finishing work and provides for the elimination of irregularities, depressions and cracks on surfaces.
2. Finishing putty - the material is intended for the final coating, because consolidates previously applied layers. The composition is distinguished by decorative characteristics, presented in different colors.

Instructions for use:

Surface preparation

The protected surfaces must be free from dirt, oil stains, leveled, dried and free from dust.

• The surface must be warmed up to a temperature of at least +5 ºС. • The surface is cleaned from dust with compressed air or brushes. • Mechanical impurities are removed with a cloth and steel spatulas. • Grease and tar stains are removed using solvents. • Chalk and lime whitewash must be completely washed out with water to a solid base. • Previously painted surfaces are cleaned of loose paint and putty. • Before applying the filler, the surface must be primed with a water-dispersion acrylic primer. • Do not apply on silicate substrates, over old oil, alkyd and other materials based on organic solvents.

Putty preparation

The putty is thoroughly mixed by hand, using a mixer or an electric drill with a special attachment until a homogeneous mass is formed. If necessary, to reduce the viscosity, the putty is diluted with tap water, but not more than 5% by the weight of the putty. The diluent is added in small portions with thorough mixing until smooth.

Application conditions

Ambient temperature: from +10 ° С to +30 ° С. Relative air humidity not higher than 80%. Lack of direct sunlight and precipitation.

Application

The putty is applied with a squeegee or trowel on a flat plastered surface. An angled trowel is used to level difficult interior corners. The control of the geometry of the plastered walls is carried out using a level. The finishing layer must be applied with a smooth movement of the trowel in one layer and in one single pass. In the case of putting putty in two or three layers, each subsequent layer is applied after the previous one has completely dried and covered with a layer of primer. The total thickness should not exceed 0.5 mm. Duration of interlayer drying: no more than 24 hours at +20 ° C. The dry layer thickness is measured using a universal ultrasonic thickness gauge or any other with a measurement error of up to 10 microns. The dried layer of putty must be sanded with an abrasive cloth. Fine sanding is carried out using a sanding float with a comfortable ergonomic handle.

Operating conditions

U1 - open industrial atmosphere of a temperate climate. Atmosphere type II (industrial) in accordance with GOST 15160. U2 - under a canopy in unheated rooms.Atmosphere type II (industrial) according to GOST 15160. У3 - in closed rooms with natural ventilation without artificially controlled climatic conditions, moderate climate, atmosphere type I (conditionally clean) according to GOST 15150. У4 - in closed rooms with artificially controlled climatic conditions including in well-ventilated underground rooms, the climate is temperate, atmosphere type I (conditionally clean) according to GOST 15150.

Storage and transportation conditions

At temperatures from +5 ° C to +30 ° C in tightly closed original packaging. Protect from direct sunlight, heating and atmospheric precipitation. Do not freeze. The guaranteed shelf life is at least 12 months.

How to properly apply acrylic putty on wood

Before applying a layer of putty, the surface must be sanded to a smooth state. Bumps, knots, shabby areas and areas affected by mold should be removed.

The surface should not be dirty and damp. It is necessary to remove the exposed tree sap and efflorescence. To improve adhesion, the restored product is treated with an acrylic wood primer.

Wait until the primer is completely dry (1-2 hours) and start filling.

The acrylic putty is applied with a plastic or metal trowel and then gently smoothed out. The layer should be thin, applied evenly and without excess, filling in all the imperfections. It should be understood that even the highest quality putty materials are not able to eliminate deep holes, therefore, working with a large amount of putty at once will not bring results. In some cases, it is better to replace an item of the product.

The ambient temperature and humidity must be taken into account. Outdoor work is carried out at a temperature not lower than 7 ° C and not higher than 30 ° C. Air humidity should be 55-75%.

After the layer of finishing material has dried, it is necessary to remove the excess with sandpaper and sand the surface.

Acryl-Putz finish and subtleties of its application

Acryl-Putz Finish is mainly used at the stage of finishing works when leveling the surface. This acrylic blend is great for correcting walls and ceilings and works well with drywall.

The main qualities of Acrylic Putz finish are as follows:

• drying takes place within a short time;

• ultimately, the surface takes on a snow-white color;

• perfect for painting;

• hides all irregularities;

• easy to sand.

The surface of the wall is perfectly sandedThe mixture dries very quickly.This putty is perfect for painting.

To process one square meter of the surface, you will need to use at least 1.5 kilograms of the mixture with a layer of putty 1 mm thick. This tool is used when it is necessary to hide the blemished spots after applying several layers of starting putty. The finishing option is used exclusively for internal work. In some cases, it is permissible to use one layer of material when it is required to hide minor defects.

After the putty has dried, you can safely proceed to painting the wall or pasting wallpaper. Even if it is planned to glue a white canvas, you do not have to worry about red spots appearing on the surface. The presented putty will reliably hide all existing imperfections of the surface being worked on.

What is the material

General information

Acrylic-based putty is a one-component polymer water-dispersion composition of pasty consistency. The material is sold ready-to-use, i.e. does not require dilution.

Thanks to their excellent performance, versatility and environmental friendliness, these putties have recently been very popular.True, it should be borne in mind that there are a large number of their varieties on sale, which we will familiarize ourselves with below.

Properties

Acrylic-based putties, like any other building materials, have their pros and cons. Therefore, further we will consider their most important positive and negative qualities.

Advantages:

They are odorless. As I said above, the composition is made on a water basis, without the use of organic solvents. As a result, it is environmentally friendly and odorless. However, this does not mean that the material is unstable to moisture. After hardening, it polymerizes and no longer dissolves with water.

• Can be applied in a very thin layer. The acrylic-based finishing putty can be applied in layers up to a millimeter. This allows you to obtain with its help a perfectly smooth surface;
• Possesses good adhesion. This allows the composition to be applied to almost any surface;
• Compatibility with any paint and varnish materials. The putty area can be painted with any paints or varnish;
• Elasticity. Thanks to this, the mixture is easy to apply and level. Therefore, it is easier to work with such a putty with your own hands than with gypsum and other analogs;
• Minimal shrinkage. The coating practically does not shrink, which greatly simplifies finishing work;

• Possesses high strength. The filled surface can withstand heavy mechanical loads;
• Weather resistance. As a result, it can be used not only for internal, but also for external work;
• UV resistant. After hardening, the material is not afraid of direct sunlight;
• Durability. The coating can last for more than a dozen years;

• The ability to color. This allows you to give the putty any color or shade;
• Crack resistance. After application, the coating does not crack.

There are few disadvantages of this material, but they are available:

• High price. Like all water-based polymer putties, the acrylic compound is quite expensive. Therefore, many use it as a finishing layer, and for the starting layer they perform with cheaper materials;
• Complexity of grinding. Acrylic water-dispersion putty is very dusty, so it is better to work with a respirator. In addition, the dust quickly clogs the sandpaper, so it has to be changed frequently.

• Do not apply in thick layers. When applied with a layer of more than 7 mm, problems may arise - cracks and slight shrinkage. Therefore, it is better to apply the composition in several layers;
• Not recommended for use at low temperatures. At temperatures less than 10-12 degrees, the elasticity of the composition is significantly reduced. Therefore, it is not recommended to carry out work in such conditions.

Specifications

As an example, consider the technical characteristics of PARADE S40 acrylic water-dispersion putty for interior use:

Putty application

Padding

As with any other putty, before proceeding with the surface finishing, it must first be primed. Exceptions are surfaces painted with organic paints.

Water-borne acrylic primer

DIY work is done in the following order:

First of all, the surface must be cleaned of dust and other contaminants.
If the base is old and glossy, then it must be sanded or sandblasted.
In the presence of mold and mildew, the surface must be treated with antiseptic compounds, then rinsed with clean water and dried.
Then the primer is poured into a special tray.
Next, a roller with a small nap is dipped into a pallet and the solution is applied to the surface

In this case, you need to pay attention so that the mixture does not accumulate in one place and does not spread.
When the base is dry, one more primer should be applied, after which the work should be stopped not for more than 12 hours.

Preparing walls for filling

Putty

The filling instructions are as follows:

• Stir the filler thoroughly before use. If the composition is frozen, you need to wait until it thaws at room temperature for two days.
• Next, you need to check the condition of the seams and the entire surface. The areas must be well anchored, otherwise the flaking coating must be removed. If necessary, seams and cracks should be expanded.
• You can set the mixture with a narrow spatula. You can use a rubber or steel trowel to apply it. Smoothing the surface can be done with a layer of no more than 1 mm.
• If necessary, 6 hours after applying the first layer, you can apply the filler again. At temperatures below 18 degrees Celsius, drying time can increase to 15-20 hours.
• 12 hours after the coating has dried, the surface must be sanded with sanding paper.
• Then the dust should be thoroughly removed and the putty surface should be covered with a water-dispersion acrylic primer.
• After the mortar has dried, you can finish it, for example, paint the surface or open it with varnish.

Sanding the wall

All pros and cons of water-dispersion putty

Among the advantages of the composition are the following properties:

• Excellent plasticity of the material. It is well applied, and tolerates changes in temperature, and moisture resistant, and is suitable as a base for any finish.
• The absence of toxic substances in the composition, therefore, does not cause intoxication of the body, even when working with putty in a closed room.
• Ease of application, which allows both a professional and a novice master to cope with the task.
• Environmental friendliness of the material and absolute safety for the human body, which makes it available for use even in children's rooms.
• Fast drying. Already after 1 hour, you can start applying the next finishing layer. Although experts recommend still waiting up to 6 hours in a normal microclimate, and at low temperatures - up to 20 hours.
• The low thermal conductivity of acrylic putty on a water-dispersion basis allows using the material to insulate the building base, which makes the indoor climate even more favorable.
• Long period of operation.
• Picky handling. So, during grinding, you do not have to make special efforts to level the surface.
• The property of air permeability, which allows the surface to "breathe", thereby preventing the development of a bacterial environment, mold and mildew.
• Easy to use. Since the putty is sold ready-made, all that remains is to pick up the spatula and apply the material to the wall.
• Hypoallergenic water-dispersion putty - and that says it all.

Against the background of all the advantages, the disadvantages seem insignificant, but still they are present. An open jar of putty should be used immediately for surface treatment.

Please note that it is not stored after opening the container and hardens too quickly. In addition, experts do not note the negative aspects of the putty.

Putty tips

The following are guidelines for using acrylics:

1. Water-dispersive putty is suitable for wall treatment, but not very suitable for ceiling surface putty. For the ceiling, a universal composition is better suited.
2. The putty should only be applied at positive temperatures, but it should not be too hot. The maximum allowable temperature for puttying is 30 degrees Celsius. If the temperature is higher, then you must either refuse to carry out work, or regularly moisten the surface.
3. The solution must be thoroughly mixed.If the solution was stored in a cold, unheated room, then the putty must be allowed to stand at room temperature before use.
4. The maximum permissible thickness of the putty layer is 3 millimeters. If the coating is thicker, it will crack.
5. If the cracks are too large, it is better to first treat the surface with plaster, waiting for the material to dry completely before the next stage of work.
6. The mortar is applied with a metal spatula or with a paint spray gun. In the latter case, the solution must be diluted with a solvent. A spray gun is more often used for finishing, and a spatula for starting.
7. If there is a need to dilute the composition, the amount of water in the solution should not exceed 0.5% of the total volume in the container.
8. Before proceeding with the finishing putty, the surface must be completely dry. Drying time is typically 24 hours. However, the waiting time may increase or decrease depending on the temperature and humidity.
9. The average consumption of putty material is in the range of 1.1-1.2 kilograms per square meter, provided that the layer thickness is 1 millimeter.

Plastered walls and ceilings

Before the puttying begins, we prepare the surface: we remove the old layers of paint or other finishing material, we clean the material from dust, dirt, oil stains and other contaminants. If there are cracks on the coating, we embroider them in such a way that the filler completely fills these defects.

Next, we apply a primer to the surface. When the primed surface is dry, you can start puttingtying.

For basic leveling of walls, you can use both starter and universal putty. Using a wide spatula, apply the putty over the surface. Movements are directed from top to bottom. As they dry, the layers of the putty are sanded with an abrasive. The finishing coat must be primed.

During this period, using a tool (float, roller), the coating can be given the desired relief or pattern.

Instead of staining, you can get by with a finishing putty of a suitable color. Such a mixture can be bought already with a given color, or you can add the desired pigment to the composition yourself.

Wood putty

Acrylic solutions are great for woodworking. Even cracked old frames, after puttingtying, acquire the hardness of a new wooden product. Also, acrylic compounds are often used to treat wooden floors, doors and other wood products.

Instructions for spackling wood:

1. We remove old paint or varnish from the surface.
2. We sand wood with sandpaper. It is necessary to remove all defects, irregularities and roughness.
3. We remove the dust that has appeared with a brush or sponge. If the area is large, use a vacuum cleaner.
4. First, we fill in obvious defects with putty: cracks, depressions, voids from removed knots, etc. If the cavity is too large, fill it in several passes, since the thickness of one layer should not exceed 3 millimeters.
5. When individual areas are processed, remove excess solution with sandpaper.
6. We apply the composition to the main surface and stretch it with a spatula parallel to the wood fibers. The peculiarity of working with wood is that it is not recommended to grind the putty coating, so as not to damage the base material. Therefore, the applied layer must be very neat and thin.

Advice! If the wood will not be painted in the future, you can choose a filler that matches the natural wood color.

Review of popular manufacturers

VGT is a company producing acrylic universal fillers. In order to create a perfectly flat surface, the product of this production is used.

Knauf. The manufacturer uses the addition of gypsum powders and polymer additives. Thanks to this, the hardening occurs very quickly, which is so useful when processing coatings. The main purpose of the mixtures is to level the surface. Thanks to additives, the elasticity of the layer increases, which affects adhesion.

As a result, after a complete analysis, you can focus on most of the advantages of acrylic putty and a variety of types. This will simplify the choice when it is necessary to process coatings and reduce the time that can be spent on the wrong choice of the wrong material.

Composition and technical characteristics (consumption per 1 m2)

The putty is based on liquid acrylic. This synthetic substance is produced by recycling acrylic acid. The varieties of putties are sold in a ready-to-use form. A plastic, viscous consistency mass of white color is packed in plastic containers of different sizes. Containers are supplied with plastic handles for comfortable transportation.

In addition to the main component, various fillers are added to acrylic putties, which change the characteristics of finishing products. Water is also included in the mass.

When added to the composition of marble chips, the strength of the building mixture increases, the product is suitable for coating various surfaces, including wood, metal. When buying, it is taken into account why the products are selected by the components of the mixture.

The material is distinguished by the following technical indicators:

• the putty dries up in 12 hours, subject to the temperature regime of about + 20 ° С;
• when covering the surface, the thickness of the putty layer is less than 5 mm;
• the material is applied at a temperature of at least + 12 ° С;
• mass density - 1.8 kg / m³;
• the shelf life of the composition is 1 year.

The consumption of building materials per 1 m² of surface is 1.1-1.2 kg, depending on the quality of the product and the thickness of the layer.

Key Features

Acrylic putty has certain characteristics, among them plasticity, water repellency, ease of application and short drying time should be emphasized. Due to plasticity, you will be able to create a coating that is not afraid of temperature extremes, shock loads, as well as prolonged exposure to frost or heat. Thus, the described compositions do not crumble and are not covered with cracks.

Thanks to the water-repellent properties, the walls gain excellent protection against decay, mold and dampness. An additional advantage is the ease of working with such a composition, which can be applied to any surface using a spatula. If necessary, cover the wall with the thinnest possible layer, add a solvent to the ingredients, pouring the resulting composition into the spray gun. The putty for painting can also be used by you, while it will show all its best characteristics, for example, it will dry within the shortest time after application. That is why it is necessary to try to work with the mixture as quickly as possible, since it will solidify in the container within an hour. The surface of the already hardened putty can be sanded using sandpaper. As a result, it will be possible to obtain a coating that allows the walls to breathe, eliminating the occurrence of mold and mildew.

Application method

Clean the surface from dirt and dust, loose old coating, clean completely from chalk and lime paint, rinse with water and detergent, then with clean water, dry. Pre-strengthen dusty and highly absorbent surfaces with the impregnating compound "Acrylit-06". The prepared surface must be dry, clean, not crumbling. Stir the product thoroughly before application. The putty is ready to use and does not need to be diluted with water. Work should be carried out at an air temperature not lower than + 150C. The thickness of the applied layer during facade work is no more than 1.0 mm; when working indoors, a layer thickness of up to 3 mm is allowed. After complete hardening of the filler, the latter must be sanded with abrasive paper and the surface must be dust-free. Then the surface is ready for further painting. It is recommended to use a special tool - stainless or plastic spatulas, graters. At the end of the work, immediately rinse the working tool with water. Putty Acrylit 406 for green entrances

Peculiarities

The putty is made on the basis of acrylic polymers, has increased plasticity and ductility. It has several varieties, it can be used for both interior and exterior work. There is a universal putty of this type, which is suitable for finishing work in an apartment, for exterior decoration of house facades and window openings.

Sold in packages:

• in the form of a free-flowing mixture that needs to be diluted with water before use;
• in a ready-to-use form.

Acrylic putty is used as a topcoat for monolithic leveling of walls or ceilings, for sealing small voids, mother-in-law of various sizes. It withstands sharp temperature changes well, has a high resistance to moisture, plasticity, and has a low vapor permeability.

In work, it is very light, evenly distributed over the surface, does not have any unpleasant odor, and dries quite quickly. Several thin layers can be applied successively on top of each other, which allows you to get a perfectly flat and smooth surface. After drying, the polymer coating does not crack, does not shrink, does not wash out during surface application of water dispersion paints.It lends itself to painting and processing with varnishes of almost all types.

Disadvantages:

• some types, when creating a layer over 7 mm, shrink, crack, therefore, for thick layers, putty is carried out in two or three stages - first, a rough layer is created, and then several finishing ones;
• sanding produces poisonous dust, therefore eye and respiratory protection methods are required.
• fine dispersion is ideal for a smooth surface, but creates great sanding problems by quickly clogging the sandpaper.

Classic color choices are white and gray. Textured options have appeared that imitate various types of textures, for example, wood.

The composition can be applied to surfaces:

• concrete;
• brick;
• metal;
• already plastered surfaces;

• wood (furniture, doors, floor, panels, ceiling);
• drywall, fiberboard, chipboard;
• old paint coatings, non-absorbent layers of glossy paints;
• glass-magnesium surfaces;
• fiber cement boards, gypsum.
