Where and how is the prospector's façade putty used?

Peculiarities

Facade plaster can be used on brick or concrete. Puttying these surfaces, you can level them and protect them from adverse natural factors. When performing any outdoor work, one cannot do without chips, chipped corners of bricks and other things, and in order to hide all these and flaws, putty is used.

Due to the different conditions for which the putty is selected, its types are also different. Frost-resistant is characterized by maximum surface protection even in very severe frosts. If you properly putty the wall, then for a long time you will not need to correct any flaws caused by time. It is best to use waterproof plaster on top of such a putty for facades.

If you want your home to always be warm and cozy, it is important to properly apply a layer of putty outside, which will ensure the desired effect. Facade putty will help to give any external surface the perfect appearance, so that decorative finishing can be done on top

How exactly to decorate the walls of a house or other building is already a secondary issue, the main thing is to hide all the flaws, insulate the walls and prepare them for further decoration.

The technical characteristics of the facade plaster must be correctly selected for the type of work that you plan. Failure to comply with such nuances can result in wasted time and poor-quality repairs. When planning plastering, you need to know what layer thickness is most optimal for a particular surface. Most often, it is determined by uneven places, focusing on convex points and depressions. The thinner the layer, the faster it dries, but also the faster it deforms from external factors.

Instructions for use

In order for the result to meet expectations, the instructions on the packaging must be strictly followed. Work with gloves, avoiding skin contact with the mixture:

• Prepare the surface: clean it from dust, paint, oil stains. The walls must be dry and sturdy.
• Highly absorbent surfaces must be primed.
• Prepare a clean container of suitable size.
• Measure out the required amount of warm water (room temperature) according to the information on the package.
• Pour the dry mixture into water gradually, stirring by hand or using a drill with a special nozzle.
• Leave the solution to ripen for 3-5 minutes and mix again.

• Proceed with the application of the mixture using a steel trowel.
• Fill up holes, cracks, irregularities.
• After the first coat has completely dried, sand and apply a primer, re-leveling can be done.
• The finishing layer is applied in a thin layer to the shed. It smoothes out only minor irregularities and, as a rule, does not require sanding.
• After complete drying, you can start painting the walls.

Mechanized application

When finishing surfaces of a large area, the Starateli facade putty can be applied using special equipment. An increased pressure is created in the apparatus and the solution is sprayed over the surface through a nozzle. After that, the putty is smoothed out with a long spatula, while the surface remains almost even.

After drying, the final sanding is carried out. With the mechanized method of application, the speed of work is significantly increased, and the facade putty lays down evenly, creating an ideal surface.

Views

Putty materials are divided into types according to several criteria.

In terms of composition, the following types of putties are distinguished:

• cement - the main component is cement and sand, and reinforcing fibers, gypsum, marble powder are used as additives;
• acrylic - based on acrylic polymer;
• acrylate - contains acrylic and latex;
• oil - the multicomponent composition includes drying oil, glue, acrylates, chalk;
• silicate - has a base of silicate liquid glass;
• silicone - the main component is silicone.

The most common composition is cement, as it has an affordable price and adequate quality. Cement-based putty is applied to all types of mineral surfaces: concrete, plaster, lime, gypsum and brick.

This composition has the following positive qualities:

• frost resistance - withstands more than 100 freezing cycles, operates at low temperatures from -60 degrees;
• strength and durability;
• fire resistance, refers to non-combustible materials;
• water resistance - resistant to atmospheric precipitation;
• environmental safety - contains natural mineral additives;
• good hiding power - it is able to close up base defects up to 1.5 cm.

Acrylic compounds are waterproof and do not crack. They create a durable elastic layer that can be further processed. Acrylic-based putties are only suitable for finishing with a layer of up to 50 mm, they are not able to fill deep irregularities due to their fine structure. When grinding, protection for the respiratory system is needed, since the composition is very dusty.

The addition of latex to the acrylate putty imparts increased moisture resistance, plasticity and durability. It is easy to apply, does not require preliminary mixing with water. But the price for such a product is much higher than for cement compositions.

Oil putty is used for leveling wooden facade elements. It has its own peculiarities in application, which limits its use. The oil putty layer must be protected with oil paint, since the components do not tolerate high humidity. Putty is applied in a thin layer up to 2 mm with multiple repetitions, which gives strength.

Silicate compounds fit well on aerated concrete, foam concrete, shell rock. Strict adherence to the application technology creates a protective vapor-permeable layer. Used as a decorative finish.

When using a silicone-based putty, a durable vapor-permeable protection is formed. The silicone layer repels dirt. There is a possibility of tinting in different colors, while the composition will be the final decorative layer on the facade. The high cost of the material becomes a limitation in application.

By purpose, the facade putty is divided into the following types:

• Basic. The granular structure is intended for leveling and restoring facades with cracks and dents up to 150 mm.
• Finish. Liquid fine structure is used for finishing with a layer of up to 0.4 cm.
• Decorative. With its help, they give various textured effects. A textured putty is used for the facade.
• Compositions for wood. For wooden structures, the vapor permeability index is important so that the outer layer of the putty does not delay the release of water vapor.

Depending on the readiness of the putty, two types of products are distinguished: dry mix and ready-made composition. Dry putty is in the form of a powder, which requires preliminary mixing with water to a certain consistency. After mixing, the components of the mixture react, ripening occurs, after which you can begin to putty. Available in bags from 5 to 30 kg.

The finished putty is a fully prepared product suitable for direct use on the surface. It only needs stirring the mixture until smooth. Ready-made polymer compositions are produced, which are poured into buckets from 2.5 kg.

Selection Tips

The main rule when choosing a facade putty is the assessment of the base. The composition of the putty mixture will depend on the quality of the working surface. For uneven walls and filling cracks larger than 5 mm, a cement-based putty is suitable. It contains grainy grains of sand, so the composition is able to fill cracks, potholes and pits up to 1 cm. Ready acrylic compositions are elastic and penetrate into the smallest pores, forming a smooth and even surface.

The type of putty depends on the base material, since different compositions have different degrees of adhesion

When buying, pay attention to what type of surface the putty mixture is intended for. For brick, concrete, plaster, gypsum, aerated concrete, cement and acrylic compositions are intended

Oil-based and acrylate putties are suitable for wood and wood-based panels.

Cement-based putty mixtures are available in gray, beige or white. In order not to distort the shade of paints and varnishes, a white putty is chosen for painting. It is even better to use pasty compositions of a snow-white color.

The instructions should indicate the possibility of coloring the finished coating. When choosing, you can take into account the possibility of changing the color of the putty mixture by adding a color or pigment.

Frost-resistant weather-resistant compounds acquire their properties if the temperature regime is observed during finishing work. Almost all putties are applied at temperatures from +5 to +20 degrees. Cement compositions harden faster at temperatures from +25 degrees. The polymer-based mixture can be operated at temperatures from +5 to +35 degrees.

In sunny weather, do not putty - the sun's rays should not fall on the work surface. Finishing work is not carried out even in the rain, since the diluted composition is negatively affected by an increase in humidity over 80%.

Depending on the amount of puttying work, the required packaging of products is selected. The weight of the mixture is calculated from the surface area and the maximum flow rate per 1 sq. m for a specific putty. The approximate layer thickness required for leveling is added to the weight. The packaging indicates the approximate consumption of the mixture for various base materials.

For how to putty the facade with your own hands, see the next video.

Cement-based putties

At the initial stage of finishing the walls from the outside, the facade putty is done with a cement-based compound with sand. Lime, gypsum, synthetic fibers and other materials can be added as plasticizers. To give a decorative look, the putty is painted. The choice of colors is limited. More often they use whitewashing of walls and finishing with synthetic materials. The main manufacturers of cement putty are Knauf and Staratel. They produce a wide range of single-component and mixed finishing materials. Consumption per m2 depends on the thickness of the layer and the unevenness of the surface. It is indicated by the manufacturer on the packaging in the optimal characteristics for the work of this finishing material. Packing of dry mix is ​​usually done in 20 kg paper bags. Lack of cement putty in its hygroscopicity. Without a protective layer of synthetic, acrylic, silicone mixture Prospector, Rudel, Pufas and Knauf, it is quickly destroyed by rain and frost.

Subtleties of choice

To choose a putty, you need to choose the right composition.

In view of the serious requirements that this material faces, it is very important not to be mistaken

Stopping your choice on something specific, you need to pay attention to the composition of the material, on which the degree of evenness and strength of the finished coating will depend

If we talk about the cement composition, then it has a more granular and coarse structure. It is best to work with ready-made mixtures of a pasty character.

If the mixture is of high quality, then its features can be distinguished:

• Fast setting and no cracks;
• Ease of use;
• Long-term preservation of plastic properties;
• It goes well with paints and varnishes that will be used over the putty surface.

It is cement plaster that is not afraid of moisture and low temperatures. It contains quartz sand, marble dust and lime flour. The composition may also contain chemical elements used to achieve better technical characteristics.

Polymer putty can be with acrylic or latex base. The latex version for external use is not used. Acrylic putty can serve as a base and be used as a finish. Its convenience lies in the fact that you do not need to dilute the mixture with water.

Almost all putty is now available as a dry and ready mix. Ready-made options are sold in special containers, tightly closed with a lid. If a dry mixture is used, then for work it must be diluted with water, and then used. The volume of packages can be different, and their choice depends on the amount of work that you have to perform. When diluting the mixture on your own, it is best to focus on the manufacturer's recommendations so that the composition turns out to be the most convenient for work.

Peculiarities

Leveling mortars for walls are called differently: someone says "putty", others call "putty". The term putty comes from the spatula tool used to apply the leveling solution. The putty originates from the German language and is translated as "spatula". These two concepts share one term - a mixture that serves for surface finishing.

For external work, a special facade putty is used, which is distinguished by its strength characteristics of compositions for interior decoration.

The following requirements are imposed on the putty for the facade:

• it must have good adhesion to various building materials;
• easy to give in to further processing on a dry surface;

• be able to apply at a low temperature;
• after hardening, it must have high strength characteristics;
• UV resistance;
• resistance to atmospheric precipitation;
• must form a wear-resistant coating that is resistant to pollution;
• the ability to tolerate temperature changes;
• after drying, no cracks should form;
• the composition should not contain harmful and toxic substances;
• the finished layer must be compatible with any paints and varnishes;
• the mortar should be plastic and easy to distribute to the work area.

Facade putty, intended for finishing external elements, performs protective, leveling, strengthening and decorative functions.

The putty is characterized by the following technical features:

• the thickness of the layer that is applied at a time;
• final drying time of each layer;
• mixture consumption per 1 sq. m;
• operation at negative temperatures;
• multicomponent or complex formulations.

What you need to pay attention to when buying a putty

In dry or ready-made form, you can purchase facade putty

This factor is the first one that should be taken into account.Slurry has a longer pot life, which means it is made for beginners

But you still need to be able to mix the solution, so it is better not to acquire it if you do not have the relevant experience in construction work. In addition, if the proportions are not observed from batch to batch, the surface may turn out to be heterogeneous, and the joints between approaches will be very noticeable.

Often consumers also pay attention to the supplier. Usually Knauf and similar brands supply more expensive products to the market, but there is no doubt about its quality.

When buying a putty for outdoor use, the base material should be considered. This could be:

• wood;
• lightweight concrete;
• Styrofoam;
• expanded polystyrene, etc.

If your home is operated under special conditions, the façade must be sized for the appropriate number of freeze and thaw cycles

Pay attention also to how often and with what intensity the walls are exposed to moisture. Water resistance is responsible for this characteristic of the putty.

When a house is built of timber, the walls must be moisture-permeable. Therefore, the facade putty is also chosen taking into account the vapor permeability.

How to choose a winter facade plaster

Moisture-resistant frost-resistant putties for outdoor use are subdivided according to the base. She is represented by: gypsum, acrylic, cement, silicate

When choosing a gypsum mixture, it is important to consider which plasticizer is used. For example, polystyrene can increase moisture resistance and frost resistance.

For outdoor work, this is suitable, because it successfully combines density with an acceptable cost. It is easy to work with them, as the mixture is elastic.

The finishing facade cladding is also created using a silicate mixture. It contains liquid glass and is also water resistant. Application can be carried out on shell rock or aerated concrete. The walls then acquire the ability to endure critical temperatures. Silicate finishes are effective where other materials fail. If, when choosing a facade putty, the readiness of the mixture for use is important, a silicate composition is the best solution. Its only drawback is that cracks form on the putty layer over time.

What kind of facade putty is waterproof

If you are looking for an outdoor waterproof finishing putty, you can choose from any of the aforementioned formulations. But the leader in the issue of stability in contact with moisture is cement mortar.

Does the facade putty protect against fungus

To create a finishing layer with antiseptic properties, you should use mixtures that contain antiseptics and antistatic agents. To do this, you should study the composition at the purchase stage. But it is better to exclude biological activity on the facade even before the time of its repair. The reasons for the emergence of biological life should be predicted

When forming layers, it is important to ensure that the outer layer is the most vapor-permeable. If you neglect this rule, the fungus will reappear, even if you apply a putty with the appropriate characteristics.

What kind of facade putty is suitable for painting

Any facade putty can be painted at your request. But highly absorbent surfaces are pretreated by closing the pores.

Which facade putty fits better on the plaster

If a plaster facade is available, you can use any option that was described in this article. The easiest way, of course, is to work with an acrylic mixture, but you will have to pay for this. Among its additional advantages, it should be noted that the mixture is elastic, which means that it disperses more easily over the surface and does not crack.

What to do next after filling the walls of the facade

And so, the walls were treated with putty, - you can begin their further refinement: apply decorative plaster, install panels, paint, insulate.The hinged system involves the installation of siding, panels, porcelain stoneware or brick finishes.

Usage Tips

The cement putty, with which the finishing work will be carried out, must be properly prepared, only after that you can start applying the first layer. Despite the fact that the applied mass is waterproof and frost-resistant, in most cases a second layer of putty will be necessary.

If you want to tile a new house that has just been built, take your time with this business. It is best to give the building time to shrink (about a year), and only then carry out all subsequent actions

It is important to take into account the temperature regime - the range from five to twenty degrees Celsius is suitable for work

It is absolutely possible to finish the house with your own hands, the main thing is to know the methodology of the process and not rush to complete all tasks. The drying time of the solution will differ depending on the temperature, humidity, and the presence of precipitation. It is not recommended to work at low temperatures, because the putty composition is mixed with water, and the winter coolness will not allow the solution to dry, it will simply begin to freeze.

For those who do not know if it is possible to putty in the rain, it is important to say that direct sunlight and moisture in the form of precipitation should not fall on the working wall, therefore it is covered with polyethylene immediately after work. You can remove the film only when everything is completely dry.

Due to the fact that the cement slurry has a vapor-permeable structure, it does not take too long.

Work must begin with cleaning all work surfaces from dust and dirt. The next step is to apply a deep penetration primer, which should dry thoroughly.

Work with the facade begins with the fact that significant depressions, cracks, etc. are closed with a starting putty. Once everything is completely dry, you can start the next step. The putty is applied to a section of the wall and leveled with a spatula. For this type of work, an exceptionally clean version of the facade putty is used, without impurities and additives.

Once everything is dry, you need to prime the finished surface and after drying, you can apply new layers. Each layer should be approximately four millimeters thick. When the process comes to an end, a finishing coat is applied to the base putty, smoothed and sanded after drying.
