Plaster Bark beetle is used as the final finishing of internal premises and facades of private buildings. The surface of the walls of the house, processed in this way, visually resembles the structure of a tree affected by a wood-boring bug. The plaster coating in operation reveals worthy qualities: it is durable, resistant to external damaging influences, quietly tolerates temperature fluctuations. How to apply decorative bark beetle plaster so that the finish lasts a long time and does not lose its appearance? The technology for preparing walls and applying plastering is presented below in stages.
Properties of the plaster coat Bark beetle
The purpose of the plaster is the processing of concrete, brick, plasterboard walls of the house, as well as chipboard and sandwich panels. Before applying it, make a base coat of warm plaster.
Mostly bark beetle is available in white, but there is the possibility of combining it with other dyes, as well as staining the finished plaster.
The finished coating protects the walls of the house from destruction and weather. It is able to withstand even the effects of aggressive chemicals (acids and alkalis).
The composition of the plaster mixture contains cement and marble chips of various fractions (0.1-4 mm). The larger the graininess of the bark beetle, the more it is spent on surface treatment. Usually plaster consumption is indicated on the packaging of the mixture..
Dilution of mix for Bark beetle plaster
To properly prepare the plaster mix, you must adhere to the instructions:
- Before applying the plaster, you should carefully read the manual on the mixture bag.
- The amount of clean water at room temperature indicated in it is poured into a container prepared in advance.
- Dry plaster mix is introduced in parts with continuous stirring to avoid the formation of insoluble lumps.
- The mixture is continuously stirred until a homogeneous mass. Then the lidded capacity is set aside for 15 minutes. Then the mass is mixed again. To prevent the mixture from setting, it should be stirred periodically during operation.
You can not add water to the finished plaster mass - this will lead to delamination and loss of binding properties.
Plaster surface leveling
This sequence of preparation should be followed.:
- The walls of the house are cleaned of old plaster, dirt and dust are wiped, stains are degreased. In the case of large recesses on the surface of the wall, alignment should first be done with ordinary cement mortar.
- Mandatory treatment of the walls of the house with an antifungal agent. This measure is especially necessary if the house is damp.
- You should also cover all the cracks with gypsum putty.
- The wall surface is primed, and then the basis for Bark beetle plaster is created: base plaster is applied on top of the primer with a layer of 2 cm, rubbed and compacted.
Finishing the facade of Bark beetle does not require such careful preparation. Exterior concrete or cement walls are coated without prior plastering.. To ensure adhesion, an hour before the work should be done wetting the surface of the wall.
A properly prepared surface will not allow to reveal various defects of the walls of the house.
Wall Coating Technology
To learn the technique of applying such a coating is not difficult, if you remember the rules for its application:
- The plaster is applied with a stainless steel grater or trowel.
- During operation, the grater is located at an angle of 60 degrees to the surface of the walls of the house. The layer should be the thickness corresponding to the size of the largest marble grain.
- If the workflow is interrupted for any reason, then the place where work is stopped is closed with masking tape. When resuming work, the plaster coating is cut, and the tape is removed.
- Checking the readiness of the surface for texture creation is done by touch. If the plaster coating does not stick to the hand, this means that the surface is sufficiently dried up and ready for further work.
- The drawing is done using a plastic grater. Keep it parallel to the surface of the wall. Depending on the intensity and direction of movement of the instrument, different patterns can be obtained. The methods for applying plaster strokes are different.
Drying of the mixture ideally occurs at a temperature of +5 to +30 degrees and air humidity not higher than 80%. When facade work, you should protect the finished coating of the walls of the house from exposure to rain and sun for 2 days.
Painting is done only after the plastered surface is completely dry. For silicate dyes, this period is three days, while acrylic dyes will require at least 14 days of drying.
The technology of applying plaster in non-standard ways
There are many alternative ways to decorate the exterior and interior walls of the house with Bark beetle plaster.. Here are the most popular ones:
- Rain. With this method, the plaster coating is applied in the usual way. Then you need to grout with a plastic grater, movements from the upper right corner to the lower left corner diagonally. The range of motion is different: both short and long.
- Bung. Apply bark beetle in the traditional way. After that, a polystyrene smoothing machine makes circular unidirectional movements with a small radius.
- Travertine. After the traditional application of Bark beetle, a plastic trowel is taken and short strokes in different directions are produced.
- Carpet. A plaster coating is applied, and then, to obtain a pattern, the surface is rubbed with a trowel in a checkerboard or cross pattern.
- World map. This method is characterized by applying two layers of plaster. First, a bark beetle is applied and a pattern is formed using a plastic trowel. The first layer is dried and bark beetle is applied again, but in small areas, making gaps. The second layer is smoothed with a Venetian trowel. Here it is necessary to apply imagination and imagination.
Application features
Since the types of such coatings are produced by different manufacturers, the polymer fillers in them may differ.
Therefore, before applying decorative bark beetle plaster, it is necessary to carefully study the recommendations given on the packaging of the mixture, and if they are not, you can look at the manufacturer’s website. The differences mainly consist in the drying time and the ratio of ingredients when mixing the plaster.
