Therefore, before the tree was painted with oil paints on natural drying oil. Now such paint is almost not released because of high costs. But they were a great success can be replaced by water enamels and varnishes, which, in addition, non-flammable. Paint on metal it is important not to pass water to the metal base, maintain a high elasticity for a long time and did not provoke corrosion. Almost any competent finishers knows that the appearance and durability of coatings depends: 60% – from surface preparation, 10-15% – of the correctness work with paint, at 25-30% – on the quality of the paint itself.
Surface preparation includes the following steps: removing precariously holding on surface areas, including remnants of the old paint (and rust, if it is metal). Full remove old paint, if it's not compatible with the newly applied, repair the surface (rough alignment, sealing cracks); drying surface hardening coating, leveling, finishing, and dust removal, in some cases, de-greasing the surface, an opaque coating primer to equalize the color and increase agdezii to paint. By the process of preparation should also include the organization and repair drainage systems, including balconies, sanitation of surfaces, etc., so as constantly moist surface color does not help. To prepare the surface, so it is strengthening, improving its appearance and increase agdezii to paint. One of the most time-consuming and expensive operations for surface preparation is the first operation. It is most commonly done by hand with brushes, spatulas and other tools. The method of sandblasting of environmental considerations practically forbidden.
But have now become increasingly applied pressure washing and chemical products (wash) to remove old paint and environmental pollution. By the way, the West is more economical every 1-2 years Wash the surface well and a bit of touch up than every 5 years to redo the entire facade. Now in Ukraine there are all possibilities.
