Anti-corrosion additives are not only passivate its further spread, but also convert already formed. If the metal surface has a strong e defeat of rust, you can use a special anti-corrosive acrylic primer with rust converter and then to produce paint. And it is quick, odorless, and with maximum comfort at work. So, when you need to paint the metal surface, not in a hurry to wear a gas mask or cotton-gauze bandage, when working with acrylic water-dispersion materials they have ponadobyatsya.Esche recently the idea of painting the metal surfaces with a water-dispersion paints seemed Utopia. The most common of the metals – iron rapidly oxidizes in the presence of water, and then water-emulsion paint.
Conventional water-dispersion paints, of course, are not suitable for this purpose. In this case, the need specialty materials, which form a dense protective coating, have anti-corrosion properties and have good adhesion to metal. All these problems, scientists were able to solve immediately. Now it came to Europe, the that the water-dispersion paints were used in difficult areas such as automobile and shipbuilding. We do let's not run that far, but consider the possibility of painting the metal surfaces in construction. Let's start with the most complex – of the roof.
Metal roofs can be divided into three groups of materials used: * First – black iron. * Second – galvanized iron. * The third – non-ferrous metals: aluminum, its alloys, copper, etc. The third group is extremely rare because of high cost, so it should not be considered. The first and second – much more affordable and widespread, although much more expensive than slate. With a black iron all understandable, it must necessarily paint. Typically, for these purposes in Russia in the old used oil and alkyd paints. Those who love to paint often can do so in the future. For 'lazy' may be advisable acrylic water-dispersed coatings for roofs with an anticorrosive effect.
