More recently, it was impossible to paint metal surfaces with water -dispersion paint without preliminary preparation of the surface. Metal today is one of the most popular materials, which in the presence of moisture is quickly oxidized. Therefore, such paints were not used for him before. In the event that it is necessary to open the metal with paint more often coatings that create special protection with high adhesion to the metal, while it is good if the paint has anti -corrosion properties. In our country, alkyd and oil paints are used in the construction industry, the use of which is minimally harmful to health. Those who do not like such paints, manufacturers offer anti-corrosion acrylic water-dispersion enamels.
They are more expensive than ordinary colors, but at the same time hold on the surface much longer than analogues. Metal, the roof is subjected to temperature fluctuations, so acrylic paints protect them without losing elasticity. Both oil and alkyd colors with elasticity have problems, so they are not the best option for use. Painting of a neocyrected roof is understandable, but in the case of a galvanized surface, problems may appear. The thing is that galvanizing after 10 years ceases to give a positive effect, and it will still have to be painted. If you paint the galvanized roof, then the effect of such protection is more significant, the roof will look more attractive. Galfied iron differs from ordinary iron, so for its painting it is necessary to choose a special paint that has greater elasticity and adhesion. Alkyd and oil paints are not adapted for painting galvanized surfaces.
