INSTRUCTIONS for the use of thermal insulation putty BRONYA EXTRA LIGHT
******************DO NOT ALLOW FREEZING!*******************
Thermal insulation putty Bronya Extra Light performs several functions simultaneously: Surface leveling, heat and sound insulation, eliminates the appearance of fungus and condensation on the enclosing structures of buildings and structures.
Thermal insulation putty Bronya Extra Light for construction and finishing works designed for leveling internal and external surfaces of concrete, brick, cement-lime plasters, gypsum blocks and slabs, gas and foam concrete, GCL, GVL, etc. with an operating temperature from -60 to 70 ° C.
Extra Light Bronya is the finishing coating.
During transportation, storage, an ultralight filler and a much heavier binder, after a period of time, is radically broken into fractions (up to the protrusion of the composition of the dry powder composition to the surface), and this is permissible.
Without following the measures described below, after transportation and storage. It is not possible to achieve the necessary state of the material for operability!
1. Preparation of thermal insulation putty Extra Light Bronya
Check the integrity of containers and seals.
Attention! The container is opened only for the preparation of the material, it is not allowed to be stored in an open state.
It is necessary to mix the material only with a mixer at a speed from 100 to 150 rpm.At least 3-5 minutes, with time control.
It is important that a possible error - the uniformity of the mass is visually achieved after a few minutes, as a criterion for a sufficient degree of mixing - is incorrect!
If necessary, additional introduction of distilled water is allowed, but not more than 5% of the volume (to achieve the necessary consistency of the material). important! When applying the material manually, dilution of the material with distilled water is PROHIBITED in a bucket. It is necessary to first transfer the necessary part of the material into a separate container, and only then dilute it.
2. Surface preparation
Before applying the putty Bronya Extra Light, it is necessary to prepare the surface to achieve the best adhesion and reduce material consumption.
Concrete surfaces.
The surface must be cleaned of flaking elements, loose areas, dust particles and dirt. If there are cracks, then they need to be embroidered. With subsequent sealing with cement-sand mortar. The surface must be pre-primed with a deep penetration acrylic primer (1-2 layers), to achieve the best result, we recommend using BRONYA series primers.
Brick surfaces.
To ensure good adhesion of the coating, brickwork should be cleaned of efflorescence and old paint, then treat the surface with an antiseptic (biocide). Also, the surface must be pre-primed with an acrylic primer of deep penetration (1-2 layers), to achieve the best result, we recommend using primers of the BRONYA series
Lime-plaster surfaces.
The base must be dry, strong, thoroughly cleaned of dust, dirt, oil and bitumen stains. The remnants of old paints should be removed. All protruding elements must be removed. The surface must be pre-primed with a deep penetration acrylic primer (1-2 layers), to achieve the best result, we recommend using BRONYA series primers.
3. Application of thermal insulation putty Bronya Extra Light
Applying recommend spatulas, plaster machines or airless sprayer (recommended brands and models airless sprayers, as well as recommendations for configuring check with the representative in your region).
Surface area of 100 m2 can be treated by using a plastering machine (e.g. Graco RTX™ 1500, Graco T-max 405 or other), or by airless spray Graco Marc V, 7 Marc Graco, Graco Marc 10 c nozzle 321.
Thermal insulation putty Bronya Extra Light can be applied at a temperature of the surface and ambient air from +15 ° C to +70 ° C (the critical value of the temperature of the surface and ambient air +10 °C at the time of application and subsequent drying within 24 hours of each layer). The surface must be dry and non-condensing, because the material is liquefied by water, and it will not dry out.
Before applying, the surface must first be treated with a deep-impregnated acrylic primer for concrete surfaces. The time of complete drying of one coating layer with a thickness of up to 1 mm is 24 hours at a temperature not lower than +15 ° C during the entire drying. According to the generally accepted painting and plastering rules, the material applied over 1.5 - 2 mm with an increase to 3.5 - 4 mm is interlayer reinforced with a wet layer of geotextile. The next layer can be applied only after the previous layer has completely dried. Applying a thicker layer of putty can lead to the formation of cracks and delaminations.
the thickness of the layer can determine the thickness wet films such as "paint brush" the material consumption 1.1 l per 1 m2 at a thickness of putty 1 mm (approximate consumption when applied with a spatula on a flat surface). The material consumption is affected by the type of surface and the method of application.
The total thickness of the coating and the number of layers is determined by the thermal calculation or recommendations of certified regional representative offices of the manufacturer.
Extra Light Bronya is the finishing coating.
4. Storage conditions and transportation Bronya Lite Extra Storage putty Bronya Extra light is in a tightly closed container at the temperature from +5 °C to +30 °C, humidity not more than 80% away from direct sunlight.
Transportation is carried out by any type of transport at temperatures above +5 ° C away from direct sunlight. The packaging of the cargo for transportation must ensure the correct installation of containers and the safety of containers. Violation of the integrity of the container leads to damage to the material. After opening the container, the shelf life is no more than 7 days.
In case of non-compliance with the instructions for applying and storing the material, the manufacturer is not responsible for the quality of the coating.
