The technology of applying the plaster “bark beetle”: training grounds
Plaster “bark beetle” may be applied on pre-prepared brick, plasterboard, chipboard, concrete, sandwich panels and a layer of insulation.
Before tiling, clean the surface of the old finish, oil stains, dirt and dust. If the base has significant roughness and cracks, it should be levelled using plaster, lime or cement mortar for plaster walls. The proportions of constituents should be strictly observed to obtain a finishing material of appropriate quality and the required strength characteristics.
A useful tip! To seal joints and large cracks, they must be sewn on using the grinder, and then patch up the plaster.
If the cladding is performed in a room with high humidity levels, then the surface definitely should be treated with an antifungal composition, which will prevent the formation of mold and mildew.
To create a good adhesion base and future plaster, level the surface should be primed using a roller, brush or spray. It will also adjust the absorbency of the prepared surface will provide uniform drying of the decorative plaster layer. In order to prepare for a future the color shade of the surface in the primer, you can add the pigment of required shade. Plaster “bark beetle” is better to use a thick acrylic primer, which can prevent excessive absorption of moisture while working with the decorative mix.
Concrete and cement-lime exterior walls do not need treatment soil mixture. To create a good adhesion will be sufficient to thoroughly moisten the surface with water one hour before the start of the tiling with plaster.
Dry a coat of primer to hard dry which will take about 40 min. at a temperature of 20 deg., apply a base coat plasters-thickness 2 mm. It should be compacted and jam. He will play the role of the Foundation for future invoices.
The description of technology of plaster facade on a heater
Many owners of country and private houses are trying to make the room the most warm. It is very often performed exterior finish of the walls with insulation, which is necessary to create a high-quality protection from the negative effects of the environment. To do this, use facade plaster that is applied over an insulating material.
Technology of plaster of external walls involves the creation of wet facade, which consists of insulation, reinforcing meshes, and textured plaster.
As insulation for the outside walls of the house under the plaster can be used by polystyrene foam or mineral wool. The first material is inexpensive and fairly simple to install product. It is used for insulation of concrete, cinder, ceramsite and brick facade.
More durable, non-flammable and breathable insulation is considered to be mineral wool in the form of a two-layer basalt or diabetology plates. This material should be used for walls of concrete, silicate, aerated concrete and timber.
The technology facade insulation mineral wool under the plaster or Styrofoam involves the use of a special adhesive which a thin layer is applied on the surface of the insulation. Further, the plate according to the principle of masonry attached to the wall surface.
After complete drying of the adhesive, insulation boards must be reinforced using dupal umbrella. On top of a heater it is necessary to fix the reinforcing fiberglass mesh with plastic ties. Three days later you can start doing the plastering the surface, the principle of which is the same as for furnish of internal premises beacons. Cost of plaster walls outside the building is an average of 400-500 rubles/m2.
Here you can use facade plaster “bark beetle”, the video application technology, which will show in detail the sequence of actions.
A useful tip! After finishing the plaster “bark beetle” of the facade of the building, it must be protected for two days from direct exposure to UV rays and rain.
Features plaster walls on beacons. Price per m2
Before the start of the finishing surface is to prepare the ground. The main event is the alignment of the walls. One of the most popular and effective ways is to run with your hands in the plaster walls on beacons. The video will clearly show the sequence of actions.
Before you begin the work necessary to prepare specific materials and tools. The first step is to buy beacons for plaster walls that act as limiters. They are metal or plastic profiles with holes. The depth is 6 or 10 mm, which is selected depending on the deviation of wall, length — 3 m. the shape distinguish T and L shaped products. Price for lighthouse plaster 6mm thick is 18 rubles., and depth 10 mm was 23 RUB.
If the walls are fairly smooth or have minor irregularities, it is possible to perform the plaster without beacons.
Also you need mortar for plastering walls. You can buy a ready material, and you can make a DIY solution for plaster walls. The proportions of all ingredients must be strictly adhered to. For making cement ratio of cement and sand is 1:2-3. To the lime mixture it is necessary to take lime and sand in the ratio 1:2-4. The clay composition is prepared by mixing 1:3-5 clay and sand. And to obtain a gypsum mortar for plastering of walls, proportions of lime, gypsum and sand are 1:1:2.
As additional tools you will need:
- scissors for metal;
- a drill to prepare the solution.
Depending on the mixture and the proportions of mortar for plastering the walls with their hands, may need more tools of different materials: wood, plastic or metal brushes.
How to choose a plaster for walls
For plaster walls is adjusted depending on the type of substrate. For concrete surfaces it is better to give preference to cement mortar or lime mixtures with the addition of cement, the amount of which affects the service life of the plaster. For brick walls fit any plaster. However, for best adhesion of concrete or brick base and the working solution should install reinforcing mesh for plaster walls. It definitely should be mounted when it is necessary to impose a layer of plaster more than 5 cm.
Finishing wood surfaces can be performed plaster-lime mixture, or a solution by adding the clay as the plasticizer. However, you should not exceed the maximum rate of this component, which may contribute to further formation of surface wall cracks. Plastering of the wooden surface to be sure is to use a reinforcing mesh for plaster walls, the price of which depends on the material of the product and an average of 150 rubles/m2.
For finishing gypsum’s blocks you can use plaster or lime stucco. Cement mortars are not compatible with a plaster surface. It does not require extra installation grids.
The most problematic are the Foundation of foam and aerated blocks, which have extremely low adhesion. Therefore, in order to provide a durable and secure grip of the base and the plaster should fill the mesh under the plaster of the walls and used solutions with special additives.
Many experts prefer a mixture of plaster that has the best performance. It does not shrink, thus preventing the formation of cracks. Also, the material generates additional heat and sound insulation. All the details of the structure is described in detail in the video “How to plaster walls, gypsum plaster”.
Important! Stucco cannot be used for concrete bases, the components of which reacts with the plaster, push it. Such plaster will quickly disappear.
How to set up the beacons for plaster walls?
The first step is to check the wall and use the level that is applied horizontally and vertically, and to identify all the hollows and projections. Before install beacons for plaster walls, it is necessary to mark the surface with a marker. Start at the corner, having receded approximately 30 cm on each side, defining locations for extreme lights. Draw a vertical line. The distance between adjacent beacons should be 160 cm Is less than the length of the rule.
A useful tip! Should not be to divide the wall surface into unequal parts. If it remains about 2 m, it is better to place the beacons at a distance of 1 m from each other.
To create horizontal marks required from floor level to retreat 15 cm and draw perpendicular to the vertical marking line. At the point of intersection of the lines to perform the holes and hammer the dowels. Next, you need to reach through them cord. From the resulting line to measure 235 cm (with ceiling height of 2.65 cm) and at the intersection with vertical lines to create the holes and to hammer the dowels.
Textured plaster “bark”: photos clearly show, is today one of the most popular facing materials, which is convenient in application and is able to create not only a beautiful cover, and to protect the base from negative environmental influences and mechanical damage. Read more about this versatile material, you can learn from this article. Read more
After laying, the surface must be thoroughly cleaned from dirt and dust and primed. This will provide a good basis for the future plaster and will prevent the formation on a wall surface of the mold and mildew.
After the wall is dry, should be ready to install beacons for plaster walls. Here we must be very careful. This will depend on the appearance of the finished surface. Metal lighthouse must be applied vertically to the wall previously mentioned the place. Next, screw in the top screw. To it is attached a plummet that will control the placement of subsequent screws and, accordingly, the location of the profile. The main objective is to flatten the profile. It will move away from the surface in places where there is depression, and fit snugly on the mount.
The procedure in more detail is shown in the video “How to install beacons for plaster walls.” All the above steps are performed for each beacon.
There is another way of placing of beacons:
- You need to prepare small part of the plaster mix. It is better to choose a plaster compound that is quickly grasped.
- Apply the solution on the wall in the places of horizontal and vertical markings which are thicker than the depth macrowage profile.
- To make the lighthouse vertically to the wall and push it into the plaster mix, having along it the rule.
Learn more about this method you can learn from a video “How to set beacons under the plaster of the walls.”
The application of plaster to the surface
Now you need to prepare a working solution, strictly following the instructions on the package material. The mixture is applied between beacons using a wide spatula with a slight excess to avoid the formation of cavities. Now, using the rule established by beacons, running the alignment layer of plaster, moving from the bottom up and periodically shaking them from side to side, evenly distributing the solution on the wall. This manipulation should be repeated several times to obtain a flat and smooth wall. Cost of wall plaster per 1 m2 depends on the type of work surface and base area.
For further decorative plaster of the walls must be removed makovye profile. This can be done in just a few hours after to grab the base layer. The voids are sealed with a wide spatula and plaster.
The final step is to grout plaster. This event should be done before full drying of the mixture. As the grout is being used more liquid in consistency mixture. She put on the trowel and smeared a thin layer on the wall area of 1 m2. So is overwritten with each subsequent square. Work is performed without interruptions.
The alignment base in such a way you can do yourself or you can enlist the help of a specialist. To date, the prices for plaster wall on beacons are in the range of 490-550 RUB/m2.
The basic intricacies of preparing plaster “bark beetle”
Plaster “bark” can be purchased in the form of dry or ready-mix. To prepare the working solution of the dry material should be clearly observe the proportions of ingredients, temperature and the sequence of actions. All information detailed on the packaging.
You should first measure out the required quantity of water, whose temperature should be between 21-23 degrees. 1 kg of dry mix will take about 250 ml of water. However, this depends on the components of the plaster and the manufacturer of the material. The working solution should be prepared in a convenient for further work Tara.
The water should be added a measured quantity of dry powder. The mixing can be done with a trowel by hand. But faster and more convenient to prepare the mixture, using the mixer construction, which should be included on medium speed. Mixing should be carried out until, until the mixture is smooth without the residue of dry matter, lumps and excess moisture on the surface of the solution. The consistency of the working solution should be similar to thick sour cream.
If the solution is too dry, it will create additional complexity during its application. It will constantly slide off the trowel, increasing the flow rate of the mixture. Too fluid will drain from the surface, leaving nasty streaks. Besides, by using a liquid solution will fail to create the necessary textural relief, characteristic of plaster “bark beetle”.
How to put on the walls decorative plaster “bark beetle”?
Before tiling should be thoroughly acquainted with the technology of application of decorative plaster on the surface, which must be pre-prepared (cleaned and aligned). Quality pre-finishing will affect the degree of obtaining a textured pattern characteristic of plaster “bark beetle”.
Work on the plastering of the walls are made integrally, i.e., one wall should be covered at once, without waiting for drying of the applied areas. Only in this case it is possible to obtain a monolithic surface without joints and extremes.
A useful tip! Before proceeding you should stick masking tape on all adjacent surfaces to protect them from the plaster.
There are two ways of applying decorative plaster: manually and with the help of special mechanisms.
Before you apply the plaster “bark beetle” by hand, should prepare the necessary tools. For works will be used with a stainless steel trowel and plastic float or trowel to create a textured pattern. On the spatula is superimposed a small part of the solution.
The work begins with the lower right corner. The plaster is applied by the tool at an angle of 60 deg. relative to the treated surface in rows, vertically or horizontally, capturing the entire wall. Plaster stretched to the layer thickness, which depends on the size of the largest grain in the mixture. It will be clearly seen when the surface will begin to form scratches and grooves. In order to verify the correctness of the work, you can view the video “How to apply decorative plaster on the wall.”
A useful tip! If the size of the wall is large enough, then it should be divided into two parts using masking tape.
If the finish wall is not finished, but there is a need to break, then you need to stick masking tape place the last overlay of plaster. When work is resumed, the tape is removed and the layer is slightly trimmed.
Before the formation of the textured pattern, it is necessary to give the surface a little bit to dry so that the plaster does not stick to hands. It will take about 20-40 min, depending on temperature conditions. To create the characteristic strokes used plastic grater. It should be held flat, slightly overlapping the treated surface. Depending on what action is to be performed using this tool will depend on the appearance of textured ornament. If the surface begins to dry, you can spray it with water. This procedure will provide additional time to perform the grouting.
After patterning, without waiting for complete drying of the plaster, it should be without pressure wipe the entire surface to visible butt-sections.
Textured surface created using plaster “bark beetle”, drying at a temperature of 10-30 deg. and a relative humidity of 80%. After the final drying of the surface to begin staining.
Please note! In 2017 the price of wall plaster per square meter starts from 500 rubles.
The pros and cons of mechanized plaster walls
When you want to do facing work on large surfaces, it is advisable to use mechanized plaster walls, the price of which is determined by the size of the surface and the finishing material. So, for priming it is necessary to apply spray, and plaster can be applied using machine.
The nozzle of the machine should be as close to the wall. It should be strictly perpendicular to the base. The operator distributes the supplied high pressure mass. It should be extremely attentive and careful, so as not to lead to the formation of marriage.
Consider the positive aspects of the use of mechanized method of the plaster walls:
- it is possible to achieve the minimum thickness of the layer of plaster, which allows to reduce material consumption;
- this method provides a uniform application of the composition, good adhesion of it to a wall and maximum strength of the finished surface;
- due to the fact that the solution is continuously fed, is secured by gradual traction of the mixture with a base;
- the mixture, which is applied mechanically, eliminates the formation of air bubbles, finding dry lumps and foreign matter.
Price per m2 mechanized plaster walls is 300-350 rubles.
The alignment of the walls is a manual process. To the textured pattern you can use grinding machines with fuzzy circle. However, it is not always possible to obtain a very pronounced surface topography.
Plaster wall machine allows you to work on facing up to 4x faster than the manual method. Thanks to the remote and short-term application of the solution on the surface is uniform solidification, which prevents the formation of cracks.
The main disadvantage of this method is the use of large equipment, which is not always easy to deliver to the destination.
Ways to create textured surface
The pattern on the finished surface will depend on the nature of the movements trowel on the plaster of the wall. Consider in more detail the actions that help to achieve relief.
To obtain the classical drawing moth bark beetle wood should perform a circular, arc-shaped non-uniform motion in different directions, lightly pressing tool.
To simulate the uneven stone surface, so-called ornament “travertine”, making short jerky movements with a trowel, moving in different directions. To get the ornament “tube”, you must use the floats from Styrofoam to make an intensive circular motion in one direction, which should have a small radius.
Create the simulated tissue surface is possible by means of crosswise movements of the float. In this case, perform vertical strokes should be from the bottom up a long slow line, and executing horizontal strokes is energetic short wave.
The picture “rain” happens when making long continuous movements diagonally from top to bottom. Start with the top right corner, moving down to the left.
With the help of plaster “bark beetle”, you can create a drawing “world map”. It is necessary to apply the first layer of material and to do his grout in any convenient way. After drying, apply another layer, but not uniformly, and in separate strokes in different directions, which you should then flatten with a trowel Venetian.
Before you begin, you can watch the video “How to apply textured plaster for the walls.”
Features of painting plastered surfaces
There are two options for coloring decorative surface:
- Adding a coloring pigment directly into the ready mix.
- Staining plastered and hardened walls.
The first option is more acceptable if you are using ready mix, to which you add a certain amount of dye for the desired shade. When using the dry mixture, calculate the dosage of colorant is very difficult. In this case, it is better to perform staining ready-made base.
For staining of the finished surface, use acrylic, silicate or latex paint, applied with a brush or roller. Acrylic should be applied no sooner than two weeks from the day finishes, and silicate paint can be used after three days.
Staining can be carried out in two stages. First time thoroughly covered the entire surface, including grooves and texture. After the surface is dry apply a second coat of a lighter or darker shade, which involves coloring only the upper part of the coating, excluding the paint in the grooves. To achieve the same effect using a semi-dry roller, which must be pre-laminated on the plywood. Also, it is advisable to use special colors with reflective properties.
A useful tip! If not paint the grooves, it is possible to obtain the illusion of depth of coverage.
Instead of staining the surface, you can scumble coating is an acrylic lacquer, which can add a pearl or color. Apply this mixture should be using a steel trowel, completely filling all the grooves on the surface of the wall.
Strict adherence to the sequence of actions when performing the surface-coated textured plaster “bark beetle” will allow to receive high quality, durable, attractive and aesthetic finish which will delight the eye for many years without losing its original appearance.
