INSTRUCTIONS for the use of thermal insulation putty Bronya LIGHT AIRLESS
******************DO NOT ALLOW FREEZING!*******************
When working with liquid thermal insulation coating BRONYA LIGHT AIRLESS, special attention should be paid to the following conditions:
1. BRONYA LIGHT AIRLESS cannot be frozen;
2. Before opening the container, it is necessary to ensure the integrity of the seals; 3. When preparing the material, it is impossible to excessively mix (see paragraph 2 of this instruction);
4. When preparing the material, it should not be excessively diluted with water (see paragraph 2 of this instruction).
1. Surface preparation
The insulated surface must be cleaned of dirt, rust, dust, old paint, crumbling elements, etc. Especially pay attention to the fact that there is no "loose" rust in the form of a "fungus" on the metal, which, after applying the LIGHT AIRLESS BRONYA, will peel off from the metal together with the coating. To clean the metal surface from rust, use metal brushes or abrasive wheels with the removal of a loose layer of rust until a metallic sheen appears. The surface cleaned from rust is treated with a rust converter, if necessary, it is maintained for 2 hours. New metal surfaces may require the removal of preservatives.
The finished surface must not contain crumbling elements, must be dry (including not condense), must not contain oily and greasy elements, must not be excessively plastic and glossy. If the LIGHT AIRLESS BRONYA is supposed to be used on ferrous metal surfaces, with an operating temperature of up to +140 ° C, then the surface must first be dust-free and degreased, covered with either an ANTIKOR BRONYA modification (preferably), or treated with VL-02 or VL-023 primer (in 1-2 layers in accordance with the instructions for the primer). If the coating is supposed to be applied to the surface of non-ferrous metal, then it is necessary to treat the surface mechanically to remove gloss, dust, degrease, treat with adhesive primer VL-02 or VL-023 (1-2 layers). If the LIGHT AIRLESS BRONYA is supposed to be applied to elements of concrete, brick, wood and similar surfaces, it is necessary to: remove loose areas, embroider cracks, remove oily inclusions, clean concrete from cement "milk", repair the surface, including inter-brick seams to reduce material consumption and recesses deeper than 5-7 mm, cement-plaster compositions. To clean the surface, use a sandblaster, a metal brush or abrasive wheels to remove gloss on the surface and remove falling off and crumbling structural elements. After mechanical treatment of the surface, a thorough dust removal should be carried out using brushes or blowers. After that, it is necessary to rinse with water to remove dirt, remaining dust, etc. After complete drying, it is necessary to prime with deep penetration acrylic primer. To apply to a part of the enclosing structures of buildings and structures made of vapor-permeable materials (concrete, brick, etc.), it is necessary to use the BRONYA FACADE modification.
2. Preparation of the insulation coating BRONYA LIGHT AIRLESS
BRONYA LIGHT AIRLESS is ready for use, it must be mixed, if necessary, by adding a little distilled water, immediately before applying to a pre-prepared surface. The amount of water depends on the temperature of the base of the application, the temperature and humidity of the surrounding air, subsequent operation and other factors. When applied to a surface with a temperature from +7 ° C to +80 ° C, the amount of water added to the material can be no more than 3%, 5%, 10% when applied with a brush and no more than 3% when applied with equipment (airless spray apparatus). When applied to a surface with a temperature above +80 ° C, it is necessary to first bring down the temperature by applying several primer layers of BRONYA LIGHT AIRLESS material diluted with 2050% distilled water according to the scheme specified in paragraph 3 "Coating". For detailed recommendations, contact the nearest representative office or the manufacturer*. With a long shelf life inside the container, stratification into fractions is allowed. When mixing, use a drill with a bladed nozzle or a mixer (check with a representative of the Bronya in your region for recommendations on the choice of equipment). Using vertical movements of the blade so as to immerse the thickened part in the liquid, turn on the drill and slowly start rotating the blade, mixing the clots with the liquid. Stir until the product becomes a homogeneous thick mass. The approximate mixing time is 3-8 minutes with a mixer, manual mixing is 7-10 minutes. If the task is to eliminate condensation, "fur coats" of frost - the material is applied with minimal addition of water and the maximum period of interlayer drying.
3. Coating
It is recommended to work with a spatula, a soft brush with long natural bristles, an airless sprayer or plaster machines (check the recommended brands and models of airless sprayers, as well as recommendations for setting them up with a representative in your region). You can apply the coating on small surfaces or areas with a complex configuration using a soft brush. Surfaces with an area of 100 m2 or more can be treated with an airless sprayer with a working pressure of no more than 60-160 bar.(IMPORTANT!!!) Suitable for working with airless sprayers Graco Marc V, Graco Marc 7, Graco Marc 10 with nozzle 321. For recommendations on the selection, configuration and work with airless sprayers, check with the manufacturer or the nearest representative of BRONYA LIGHT AIRLESS. Also see additional tech.a map for working with airless sprayers). An insulating coating can be applied to a surface with a temperature from +7 ° C to +120 ° C and a relative humidity of no more than 80%. For better adhesion of the material to the treated surface, it is recommended to apply a primer layer on the prepared surface with a liquid (like milk) composition of the material diluted with 20-50% distilled water. The period of complete drying of one coating layer with a thickness of 1 mm is at least
