Recommendations for painting metal surfaces

 

 

The main problem of any metal (both black and non-ferrous) is corrosion. This term is often quite narrowly understood only as rust, but in fact corrosion is a process of destruction of a material under the influence of an external environment.

It is almost impossible to create conditions in which metal products would maintain the “status quo” without additional anti-corrosion treatment - iron and its analogues always tend to self-destruction.

It is obvious that corroded metal can no longer be considered high-quality and reliable: the surface loses its strength, decorative properties and eventually becomes completely unusable.

 

Corrosion-resistant paint: which product to choose?

 

On ferrous metals, corrosion looks like rust familiar to our eyes, on non-ferrous metals it can appear as a white-green coating.

Not only does this weaken the metal, corrosion spoils the appearance of the product.

Specialized paint successfully copes with both problems.

One of the main conditions for the success of the enterprise is to ensure good adhesion to the substrate, for this the treated surface must be prepared for painting.

 

 

Paints and varnishes for ferrous metals are more widely represented on the market, since there is more demand for them. In addition, the processing of non-ferrous metals is more expensive, and primers for them, as a rule, belong to the upper price segment.

 

Preparation before painting

 

 

First of all, the item to be painted must be cleaned.

On the packaging of some materials it is indicated that they can be used directly on top of corrosion, but this refers to firmly held rust, and not layers lagging behind the flakes.

Whatever paint you choose, the surface needs to be thoroughly cleaned with a stiff brush or even sandpaper to remove old paint and flaking rust.

Then the surface is thoroughly washed with special cleaners and dried.
