Decorative plaster bark beetle createscharacteristic surface with grooves, imitating a wooden surface eaten by a bark beetle. It is used as a decorative finish for vertical surfaces inside and outside brick or concrete structures and when performing thermal insulation facade coatings.
Decorative plaster bark beetle provided onthe market of building materials by many manufacturers, because the composition may differ slightly. Different types of polymeric fillers may be contained in bags of different companies, on which plaster application technology will depend on itself. Therefore, before starting work, you should familiarize yourself with the instructions, which should describe the time regimes and the formulation of batches.
Во всех марках Короеда присутствует мраморная the crumb 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 consumption of plaster is determined: the larger they are, the greater the consumption. On the packaging of the mixture indicates the average consumption of this brand, which is necessary to calculate the number of packages per square of the surface to be coated.
Often decorative plaster barkAvailable in white. To give it the desired shade, a special dye is used, or staining occurs after the finished layer has dried on the wall with silicate or acrylic paints. With the help of tinting you can get the original unique facade or interior.
Decorative plaster bark beetle has suchproperties as a high indicator of strength, vapor permeability, frost resistance, resistance to high temperatures and direct sunlight, resistance to precipitation, acids, alkalis and industrial gases. The surface covered with it for a long time does not lose its original attractiveness, even if it is prone to high humidity.
Facade plaster bark beetle is designed toapplied on concrete, brick, plasterboard walls, surfaces made of sandwich panels, chipboard or solid fiber boards. Can be used as decorating the base of warm, barite or ordinary plaster.
Перед нанесением Короеда нужно произвести surface preparation: clean it from grease, oil, dust and other contaminants. In case of high humidity and unevenness of the base, level it, apply antifungal agent and dry it. If there are cracks, they need to be filled.
Наличие тонкого слоя грунтовки значительно simplifies the application of a mixture of bark beetles. The plaster is applied only after the primer is completely dry - after about 6 hours. For exterior work, you can not use a primer, but in this case it is necessary to moisten the walls abundantly with water an hour before the application.
Чтобы приготовить смесь для оштукатуривания, в water from 15 to 20 ° C is gradually added to the bark beetle plaster, stirring continuously, until the lumps completely dissolve. Then incubated for 5-10 minutes and again mixed. The mixture must be used for the time indicated on the package. Dates vary for different brands, on average, they vary from an hour to three.
The mixture is applied to the walls with a steel trowel.under a slope of 60 °. After drying, lightly treat it with a plastic or wooden float. The direction and type of grooves is formed by the directionality of the movements of the grater: vertical, horizontal, circular or cross.
The work must be continuous, and inIf necessary, interrupt the border with masking tape. During the application of plaster temperature should be from 5 to 30 ° C, and the humidity should not exceed 80%.
