Use Metal Cooking ground According to experts, 70% success when working with metal substrates depends on proper preparation of the base. Rate his condition, clean, well pick up a system of protection (not forgetting the conditions), apply it without violation of technology - these are the basic rules to observe are not too difficult. Prepare metal surfaces for painting comes to clean it from dirt, loose rust, grease and priming. By defining the state substrate and the type of pollution can get down to business. Fats, soot, dirt, dust and soot can be removed with soap and water or non-aggressive detergents. A new surface after cleaning and before applying the primer additionally treated with cleaning solvents. Older surfaces require a more careful attitude. Old paint and varnish are removed mechanically (using sandpaper or destroyer), chemical (Solvent used), or thermally (by burning, which is very travmoopasno) way. If there is no need for complete removal of old layers of paint, and with careful examination you have not noticed on the surface of bubbles and cracks, issuing the rust, then the base can be sand and, filled the open areas, to begin painting. Do not forget to check out the old and new paint on the compatibility! For this test should be painted on area of 10-15 cm2. If the coating dries well and is not making no obvious defects - all in order. Painting of metal painted metal surface gets completed form and additional protective properties. It is formed light, water and weatherproof film, which prevents oxidation, and the period of coverage is extended to 6-8 years or more. Manufacturers recommend the use of paint for finishing paints, enamels and varnishes based on acrylic (Silky matt, thin-layer paint-wagon-class for interior and exterior), alkyd-based enamel 115 and silicone resins, paints and special purpose vehicles...

Cellulose Fibre Thermal We consider three types of modern insulation: mineral wool, expanded polystyrene and ecowool. If the mineral wool has long been used in construction in Russia, the polystyrene is a relatively new material, and ecowool and at all exotic. All three materials with the technology of production do not rot, have good insulating properties, are inexpensive and easy to use. Mineral wool are processing of molten rock or slag. In the resulting synthetic vitreous fibers are added binders. It has good heat and sound insulation properties; when wet, these quality of mineral wool are significantly reduced. This insulation is not flammable. The characteristics of mineral wool thermal conductivity, W / (m * K): 0,039-0,054 Group of combustibility: NY, G1, G2 Resistance to deformation: Average Water and biostability: low Destruction temperature, C 350 Density, kg / cu. m: 75-350 life, years: 20-30 Ecowool or cellulose wadding, as a rule, consists of 81% of the treated pulp at 12% - of preservative, and by 7% - of the flame retardants. In fibers of the material is lignin, which gives the sticky when wet. All components of this material are non-toxic, non-volatile, harmless to human natural ingredients. Cellulose insulation does not support combustion, not rot, has good heat and sound insulation. Ecowool capable of holding up to 20% humidity, which has almost no effect on the heat-insulating properties. Material easily gives moisture to the environment and when dry does not lose its properties. Characteristics of Cellulose Fibre Thermal conductivity, W / (m * K): 0,036-0,041 flammability Group: G1, G2 resistant strains: low Water and biological stability: the average temperature of the destruction, C 220 Density, kg / cu. m: 30-96 life, years: 30-50 Expanded polystyrene - the material class of plastics, characterized by cellular structure. Characterized by high water and biopersistence, low specific gravity....
