Paint paint strife
Well, of course, we are not talking about simple chalk paint, which is the granddaughter of whitewash. Modern paints only superficially look like the most common water-dispersed compositions. But in fact, they are additionally supplied with various additives that make them resistant to ultraviolet radiation and cracking.
Let's say more: now water-dispersed paints are used in... shipbuilding, and there, as you know, it is of paramount importance to protect metal body against aggressive salt sea water, in which the destruction of unprotected metal occurs very swiftly.
Is it possible to paint the roof with water paint
This is not a fence to paint, the roof is very important. Minor damage to the coating can have a detrimental effect on an expensive interior, and repairing the roof is not a cheap task. Is it worth the risk using water-dispersed formulations?
Nowadays, metal roofs are a popular option in construction. And if everything is clear with roofs made of non-ferrous metal, no one paints them, then with galvanized and ferrous metal such a need may arise. What can you advise?
For the roof, water-dispersed enamels with an anti-corrosion coating are suitable. And by the way, this paint will last longer than ordinary alkyd or oil enamel.
As for painting galvanized steel, such a need may arise only 15 years after installation, and then in places where the galvanized surface has been deformed. But professionals advise not to wait for this moment, but to paint the galvanized roof, as they say, for every fireman.
By the way, alkyd and oil enamels, in principle, do not stay on the zinc surface for longer than one season.
For your information! Some craftsmen independently make a semblance of metal, corrugating iron. But in this case, painting is required, and acrylic-based paints will be the best option.
Why are special objects painted with water-dispersed paints?
A distinctive feature of water-dispersed compositions is their incombustibility. It is this property that made them popular for the design of special objects with an increased fire hazard.
Where else are water-based paints used? They paint railway cars, garages, industrial hangars, Gates and fences, heating batteries. There are also water-based rubber paints on the market, which show incredible results in protecting metal from corrosion.
For your information! Water-dispersed paints for metal surfaces can be used even on rust, and the composition not only stops the spread of corrosion, but also converts rust.
And of course, one cannot fail to mention such an important point: working with water-dispersed paints does not require the use of respirators or constant ventilation, you will not feel the smell, and your body will not come into contact with the paint will be dangerous.
And to prove the above, here is this video about the use of acrylic paint for radiators:
