Specification

Ready to use. It creates a weather-resistant coating with low water permeability, resistant to mechanical load, aggressive nature effects and different dirt. It is permeable to vapor, flexible, highly adhesive and can cover small cracks. It is easy to use and to form a structure. It can be tinted manually with pigment concentrate "Farbex Color", other waterborne color pastes or with a color machine according to NCS color range and others.

Sphere of application

It is intended for finishing coating with the structure of "bark beetle" when it is applied on porous and gas concrete surfaces, mineral plasters, gypsum boards, concrete, gypsum, isolating systems, stone walls, asbestos cement indoors and outdoors. It is recommended for surfaces with high exploitation load and also for the facade insulation systems.

Application instruction

Preliminary preparation

Non-coated surface: Clean surface from loose coatings, dust, oil, grease, and other dirt. Surface defects shall be plastered. Treat the surface with antiseptic TM Farbex for protection against fungi and mould. Freshly applied stucco shall not be treated within 2-4 weeks.

Previously coated surfaces: Clean thoroughly the surface from old loose coatings (loose paint or varnish coats) mechanically (a scraper or a wire brush), thermally (hot air dryer, infrared radiation) or chemically (paint removing products). Chalk or lime-chalk coatings shall be removed till hard surface mechanically. The surfaces shall be also cleaned from different dirt. Surfaces, previously coated with alkyd or oily enamels, shall be sandpapered. Surface defects shall be corrected with Putty TM Farbex. Corrected areas shall be dry and hard enough. Polish the surface with sandpaper after it gets completely dry and remove abrasive dust. The surfaces, affected with mould, algae or moss, shall be cleaned thoroughly. After that apply antiseptic for mineral surfaces TM Farbex. Then treat it as a non-coated surface.

Priming

Highly absorbing surfaces shall be treated with Deep-penetrating silicone primer TM Farbex.

It is necessary to apply a layer of silicone paint-primer with quartz filler TM Farbex. The paint-primer shall be tinted in the color of decorative stucco.

Applying

Stir thoroughly before use.

The product shall be applied on the surface in 1 layer with a stainless trowel or an appropriate machine for the application. Remove the extra product from the surface right after application making the grain-size thickness layer. Form a structure in 3-5 minutes with a plastic trowel. In accordance with the direction of the tool move (vertical, horizontal or circle like, etc.) different structures of the "bark beetle" are achieved. The time between stucco application and its structuring can vary depending on the temperature and air humidity, the temperature of a base surface, degree of its water absorption and the body of the product. 

If the application is performed manually there shall be two persons as the work on one flat area shall be performed constantly with the "wet to wet" method. The structure of the surface shall be formed with the same instrument on the whole surface. Don't let the edge of the applied product getting dry.

When the product is applied with a machine, its nozzle shall be chosen exactly in accordance with the grain size (nozzle size shall have a diameter of 4 grains). Required working pressure shall be 0.3 - 0.4 MPa (3-4 bar).

It is recommended to use the product of one batch to avoid color shade deviation and uneven structure on the surface. If the product in use is from different batches, it is necessary to mix it.

The temperature of air and the surface under application shall be from +5 ° С till +30 ° С, maximal relative air humidity shall be 80%.

Tool cleaning

Rinse the tools with water after appliction. Don't let it getting dry. Rests of dry stucco can be removed mechanically.

When calculating the area to be painted, you need to subtract the area that will not be painted. (windows, doors, etc.)

Paint consumption may vary depending on dilution and uniformity of application of the paint.
