Decorative plaster Bark beetle - fine furnish for an interior and a facade

Decorative plaster Bark beetle creates a characteristic surface with furrows, imitating a wooden surface bitten by a beetle-bark beetle. It is used as decorative finishing of vertical surfaces inside and outside of brick or concrete structures and when performing heat-insulating facade coatings.

Decorative plaster Bark beetle is provided in the building materials market by a lot of manufacturers, because the composition may be slightly different. In bags of different firms may contain different types of polymer fillers, on which the technology of plastering actually depends. Therefore, before starting work, you should read the instructions, which should describe the time regimes and the formulation of batch.

In all grades of Bark beetle there is a marble crumb in the size of fractions 0,1-3,5 mm, acrylic copolymer, cement and fibers to strengthen the structure of the coating. Depending on the size of the crumb elements, the plaster consumption is determined: the larger they are, the higher the consumption. On the package of the mixture is indicated the average flow rate of this brand, which is necessary to calculate the number of packages per square of the surface to be coated.

Often decorative plaster Bark beetle is produced in white color. To give it the right shade, a special dye is used or the coloring takes place after the finished layer has dried on the wall with silicate or acrylic paints. With the help of tinting, you can get an original unique facade or interior.

Decorative plaster Bark beetle has such properties as high index of strength, vapor permeability, frost resistance, resistance to high temperatures and direct sunlight, stability to atmospheric precipitation, acids, alkalis and industrial gases. The surface covered by it for a long time does not lose its original attractiveness, even if it is predisposed to high humidity.

Facade plaster The bark beetle is intended for application to concrete, brick, plasterboard walls, surfaces from sandwich panels, particleboard or hardboard. Can be used as a base decoration from warm, barite or ordinary plaster.

Before applying the bark, you need to prepare the surface: clean it of grease, oil, dust and other contaminants. At high humidity and unevenness of the substrate, it should be leveled, apply an antifungal agent and dry. If there are cracks, they need to be filled.

The presence of a thin primer layer will greatly simplify the application of the Bark beetle. Plaster is applied only after the priming coat has dried completely - after about 6 hours. For outdoor work, you can not use a primer, but in this case, it is necessary to moisten the walls with water a full hour before the application begins.

To prepare the mixture for plastering, in the water at a temperature of 15 to 20 ° C, gradually add plaster Bark beetle, continuously stirring, until the lumps dissolve completely. Then stand 5-10 minutes and mix again. Ready mixture should be used for the time indicated on the package. Terms vary for different brands, on average they vary from an hour to three.

On the walls, the mixture is applied with a steel trowel at a slope of 60 °. After drying, light movements are treated with a plastic or wooden float. The direction and type of grooves is formed by the direction of the grater movements: vertical, horizontal, circular or cross.

The performance of the work must be continuous, and in case of necessity it is necessary to break off along the border pasting the painting tape. During application of the plaster, the temperature should be from 5 to 30 ° C, and the humidity should not exceed 80%.
