*Material consumption depends on the quality of surface preparation, the method of application, the tools used, the skill of the workers, and may differ from the indicated values.

Purpose and properties
Water-based facade paint based on liquid glass for exterior and interior work in buildings and structures of types A, B, and C. It is optimal for painting historical and cultural heritage sites with plaster substrates containing a high proportion of lime binder, as well as for repair and restoration work.
High resistance to temperature changes and heavy precipitation; it retains its color for a long time. Does not form a film. High vapor permeability and alkali resistance.

Protective properties
Protection against fungus and mold — the alkaline nature of the paints prevents microorganisms from developing on the surface. Excellent adhesion. The paint forms a strong chemical bond with the mineral surface, which ensures a long service life of the coating and resistance to mechanical damage.

The paint is produced in base A and can be tinted using a computer (machine) method into a limited number of colors from RAL, NCS, and other color catalogs. Base A is intended for tinting into light and pastel shades and can also be used as a white paint.

The organization performing the tinting is responsible for the tinting result. Depending on the application conditions, as well as the texture of the surface being painted, the actual color shades may differ slightly from those presented in the color catalog. Before use, it is necessary to perform a test application and check the dried coating 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 to pre-mix materials from different batches in a 1:1 ratio; the application technology must remain unchanged.

Requirements for the substrate

• The substrate must comply with the requirements of SP 71.13330.2017:
• Concrete, reinforced concrete, cellular concrete — age over 3 months and relative humidity no more than 4%. Cement-sand, cement-lime plasters — age 28 days and relative humidity no more than 4%. BERGAUF ISOFIX, BAU PUTZ ZEMENT, UNTER BAU, GLATTE ZEMENT, FINISH ZEMENT — age over 3 days and relative humidity no more than 6%.

Surface preparation

1. Clean the surface of dust, dirt, efflorescence, and oil stains. Remove poorly adhering paint and plaster with a sandblasting machine, hydro-sandblasting machine, or a steel brush. Heavily chalking and unstable surfaces must be cleaned down to a solid base mechanically or by washing with water under pressure.
2. Level shallow depressions, cracks, and chips with Bergauf Finish Zement putty and sand them down. In case of fungal or mold damage to the surface, treat it with a sanitizing agent, following the relevant instructions. Treat glossy concrete surfaces (cement laitance) with a sandblasting machine or a steel brush to create a profile suitable for painting.
3. For priming, it is permissible to use Mineral Techno Pro silicate facade paint, diluted with water in a 1:1 ratio by weight.

Working conditions
The surface to be painted must be dry and clean, the base temperature for work must be at least +5°C, the room temperature during paint application must be between +5°C and +35°C, and the relative humidity must be below 80%. It is recommended to use paint from the same production batch to avoid differences in the shade of the finish layer.

Material preparation
Stir the paint thoroughly. It is necessary to stir with a wide, flat stick or a construction mixer at low speeds, carefully, avoiding the formation of air bubbles, for 1–3 minutes. It is not recommended to mix the material by shaking the closed container. After transportation and/or active mixing, if air bubbles appear, the paint needs to settle until they disappear.

Application technology

• Apply the paint to a prepared, dry, clean surface with a brush, roller, or spray gun evenly in 2 coats. It is recommended not to take breaks when painting a continuous surface; in areas of "overlaps," work using the "wet-on-wet" method. Work should be finished at architectural boundaries (at the corners of the building, under downpipes, etc.).
• For rough surfaces such as textured plasters, brick, concrete blocks, and relief ceilings, it is recommended to use rollers with a pile length of 12–25 mm. For smooth surfaces such as putties, plasters, and concrete, use rollers with a pile length of 8–12 mm.
• The paint is ready for use; for application with a brush or roller, it can be diluted with water by no more than 5% if necessary. When diluted with water, the paint should be used within 4–8 hours. The quality of tap water affects the technical parameters of the material.
• To obtain a rich color and improve the appearance of the surface, two coats of paint must be applied.

Precautions
During work, avoid exposure to direct sunlight and high humidity conditions. After finishing work, wash hands and tools thoroughly with warm water.
Liquid potassium glass reacts chemically with glass, ceramics, glaze, metals, lacquer coatings, etc. These surfaces and elements must be covered before painting. In case of accidental staining of these surfaces, the contamination must be cleaned off immediately with water.

Storage and transportation conditions
Store and transport in a tightly closed container at a temperature of no less than +5°C and no more than +30°C. The bucket with the product should be protected from excessive heat and stored away from direct sunlight. If conditions are met, the guaranteed shelf life in the original sealed packaging is 12 months from the date of manufacture.

Safety
The product is fire and explosion-proof and does not contain flammable components.
