Appearance and durability of the coating depends on 60% of the surface preparation by 10-15% – from working properly and the paint by 25-30% – on the quality of the paint itself. Before applying the paint to thoroughly prepare the surface in To ensure high-quality coverage and the duration of his service. Surface preparation is the removal of corrosion products, old paint, grease and other contaminants. You need to see paint cover. If the old paint is firmly on the surface in the form of a continuous layer, it should be washed with warm water and detergent and dry. If the cover is held loosely, it must be fully remove. Surface preparation can be performed chemically and mechanically. In the application of chemical methods of treatment in the alkaline cleaning formulations or active solvent (xylene), depending on the type of pollution, which contributes mainly degreasing the surface.

Mechanical surface cleaning is carried out by: no special tools (brushes, sanding machines), sand fraction, a mixture of sand and water. Using these methods, you can get a good clean surface with a uniform surface roughness, which promotes adhesion of paint film the best. After Priming clean the surface it is applied acrylic primer base coat, which is the basis of coverage. Ground creates a strong bond between the surface and the subsequent paint layers, as well as provides a high protective ability of the coating. Priming produce immediately after the completion of the preparation of the surface. The primer is usually applied with a brush, a paint sprayer. Soil layer should be thin on compared with the outer layers of paint.

The drying of the soil should be carried out under the regime of technology. Shpatlevanie for surfacing must Shpatlevanie. Putty EP-0010 applied in a thin layer as thick and elastic enough layers of fillings can crack during operation, as a result will be lowered protective properties of the coating. Each layer of putty to dry well. The number of layers is not must be greater than three. Recommended thickness of the layer shpatlevochnogo no more than 3 mm. It is better to spend a few days for additional tests fillings, than to bear huge losses due to rework. Grinding Zashpatlevannaya surface after drying has burrs and rough edges, which can be removed by grinding. In the process of grinding the processed surface is exposed to many fine abrasive grains, resulting in formation of the risks and it becomes opaque. This significantly improves the adhesion between the layers of the coating. Grinding with abrasive skin on paper and fabric base.
