Specification

It is ready to use. It creates a weather-resistant coating with low water permeability, resistance to mechanic load and aggressive nature affects. It is vapor permeable, flexible, has high adhesion to many kinds of surfaces. It can cover small cracks. It is easy to use and to form a structure. It can be tinted manually with a pigment concentrate Farbex Color and other coloring pastes or with a color machine according to NCS color rate and others.

Sphere of application

It is intended for finishing coating with "lamb" structure on porous and gas concrete surfaces, mineral stuccos, gypsum panels, concrete, gypsum surfaces, insulating systems, walls made of stone, asbestos cement indoors and outdoors. It is recommended for coating of the surfaces with high operation load  and for insulation of facades.

Application instruction

Preliminary preparation

Non-coated surfaces: Clean thoroughly from loose coatings, dust, oil, grease, and other dirt. Defects of the surfaces shall be plastered. It is recommended to treat the surface with Antiseptic TM Farbex for protection against mould and fungi. New stucco coatings shall not be treated before 2-4 weeks.

Non-coated surfaces: Clean the surface thoroughly from old loose coatings (loose paint or varnish) mechanically (a scraper, a wire brush), thermally (hot air dryer, infrared radiation) or chemically (paint removing products). Chalk and lime-chalk coatings shall be removed till hard surface mechanically. The surface shall be cleaned from all kinds of dirt. Surfaces previously coated with alkyd or oily enamels shall be sandpapered. Surface defects shall be corrected with Putty TM Farbex. Corrected areas shall harden well and dry. The dried surface shall be sandpapered. The abrasive dust shall be removed. Surfaces covered with mould, algae, moss shall be thoroughly cleaned. Then apply antiseptic for mineral surfaces TM Farbex. Then treat the surface as non-coated surfaces.

Priming

Very absorbing surfaces shall be treated with deep penetrating silicone primer TM Farbex.

It is necessary to apply a coat of paint primer with quartz filler TM Farbex. 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 appropriate applicating machine. Remove extra product from the surface right after application making the grain-size thickness of the layer and form an even structure with a plastic trowel. Depending on the tool direction (wave or circle like, etc.) different structures of the surface are achieved. 

If the application is performed manually there shall be two persons as the work on one 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 get too dry.

When the product is applied with a machine the nozzle shall be chosen exactly under the size of the grain (nozzle size shall have a diameter of 4 grains). Required working pressure shall be 0.3 - 0.4 MPa (3-4 bar). If the required structure achieved with machine application, there is no need to use structure forming tools.

It is recommended to use the product of one batch to escape color shade deviation and achieve even structure on the surface. If the product of different batches is used, it is necessary to mix it.

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

Tool cleaning

Rinse the tools with water after application. Don't let them get 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.
