* Material consumption depends on the quality of the substrate preparation, the application method, the tool used, the qualification of the workers, and may differ from the specified values.
**A certain content of particles differing from the main color is allowed, which does not affect the technical characteristics of the product. This is explained by the presence of fillers of natural origin in the composition.
*** The stated quality indicators and recommendations are correct for an ambient temperature of +20°C and a relative air humidity of 60%. In other conditions, the drying and adjustment time may differ from those specified.

Purpose and Properties
High-quality ready-to-use acrylic plaster for use in facade thermal insulation systems based on mineral wool and expanded polystyrene (except for plinths), as well as for interior finishing in dry and wet rooms in buildings and structures of types A, B, C.

Technical Features
Can be tinted in pastel and saturated colors. Resistant to shrinkage cracks. Easy to apply and structure. Durable and weather-resistant. Vapor-permeable.

Tinting
Decorative plaster is produced in the form of a base and can be tinted by computer (machine) method into RAL, NCS colors, and other color catalogs. Manual tinting is possible using water-based tinting pastes with high light and weather resistance. It is recommended to add no more than 5% of colorant, as its overdose negatively affects the strength and processability of the coating application.
The organization performing the tinting is responsible for the tinting result.

Color Rendering Features
Depending on the application conditions and the texture of the surface being painted, actual color shades may differ slightly from those presented in the color catalog. Before use, a test application must be performed and the dried coating checked for color compliance.
To avoid differences in shade, it is recommended to use a product from the same production batch on one visual plane (the batch number is indicated on each package) or pre-mix materials from different batches in a 1:1 ratio; the application technology must remain unchanged.

Color Recommendations
It is recommended to use BERGAUF FACADE GRUNT primer in a color close to the color of the plaster being used.
The use of intense or dark colored materials with a reflection coefficient of less than 25% on facades should be limited to small surfaces occupying no more than 10% of the facade, for example, individual architectural details.

Application Technology
Work should be performed according to SP 293.1325800.2017.
Before application, the plaster must be thoroughly mixed, as product separation may occur during storage. Dilution of the plaster with water in an amount of no more than 5% of the material weight is allowed.
Apply the plaster with a stainless steel trowel at an angle of 60° to the surface; the layer thickness should correspond to the grain size of the plaster. Within 25–35 minutes after application (depending on temperature and humidity), form the required texture using a plastic float. The plastic float should be held parallel to the surface, and the texture should be formed with light movements, without pressure.

Methods of Texture Formation:
The "lamb" (pebble) texture is formed with circular movements. The "horizontal bark beetle" texture is formed with left-to-right movements. The "vertical bark beetle" (rain) texture is formed with up-and-down movements. The "cross bark beetle" texture is formed in 2 stages: first, diagonal movements are made from the top right to the bottom left, resulting in long and short lines, then the pattern is applied crosswise from the top left to the bottom right.

Work Execution Features
If it is necessary to stop work, masking tape is applied along the edge of the plaster layer, which must be removed before the plaster hardens. To obtain a uniform texture, a sufficient number of workers should be provided at each level of the scaffolding, and the connection of sections between adjacent levels should be performed using the "wet-on-wet" method.
After application, the decorative plaster should be protected from direct sunlight, wind, and rain for the first 2–3 days. Under such conditions, it is recommended to cover the scaffolding with a special mesh or film and install water drains on the building. Do not allow freezing or drying out.
Interior finishing should only be performed in well-ventilated rooms, and after completion of work, air circulation should be maintained until the coating is completely dry.

Subsequent Work
For painting the surface of the decorative plaster, it is recommended to use acrylic, silicone, or silicate paints. Painting is carried out no earlier than 3–5 days later, depending on environmental conditions.

Tinting
Tinting is possible using water-based tinting pastes with high light and weather resistance, in accordance with NCS, RAL, and other tinting systems. Depending on the application conditions and the texture of the surface being painted, actual color shades may differ slightly from those presented in the color catalog.
It is recommended to add no more than 5% of colorant, as its overdose negatively affects the strength and processability of the coating application. To avoid color variation, it is recommended to use a product from the same production batch on one surface (the batch number is indicated on each package) or pre-mix materials from different batches in a 1:1 ratio; the application technology must remain unchanged.
The organization performing the tinting is responsible for the tinting result. Before use, a test application must be performed and the dried coating checked for color compliance.

Color Recommendations
It is recommended to use "Bergauf FACADE GRUNT" primer in a color close to the color of the plaster being used.
The use of intense or dark colored materials with a reflection coefficient of less than 25% on facades should be limited to small surfaces occupying no more than 10% of the facade, for example, individual architectural details.

Tool Cleaning
Clean tools with water immediately after work. If the tools were not cleaned immediately, they can only be cleaned mechanically later.

Limitations
It is forbidden to work during precipitation, fog, as well as on wet surfaces after rain and at temperatures below +5°C and above +35°C.

Safety
Attention! The product is fire and explosion-safe and does not contain flammable components.

Storage and Transportation Conditions
Subject to the conditions, the guaranteed shelf life in closed original packaging is 18 months from the date of manufacture. Store and transport in tightly closed containers at a temperature of at least +5°C and no more than +30°C. The bucket with the product should be protected from excessive heat and storage under direct sunlight should be avoided.

Attention!
5-fold freezing is allowed for a total duration of no more than three weeks at a temperature not lower than minus 20ºC.
