Since ancient times, metal has been one of the most necessary materials, both in production and in everyday life. At the same time, despite the strength, reliability and a sufficiently long service life, even structures made of metal material can be exposed to negative environmental factors.

A forged product is a different metal structure that is assembled in any way from individual elements. These include various types of fences, gates, gates, fences on balconies and stairs, as well as many other products. Before painting, their surface must be primed. In addition, paint and primer can be used in pairs.
Thanks to art forging, you can make metal things not only practical, but also aesthetic. All this makes art forging an ideal option for decoration in the exterior and interior. But in modern conditions, it is the painting of forged products that is the best way to prevent corrosion, thereby extending their useful life.

Initially, primary processing of metal surfaces is carried out, and only then paint and varnish material is applied. If forged products have long been under the direct influence of environmental factors, it will be necessary to pay due attention to their preliminary processing. Thus, it will be necessary to remove the paint that has already peeled off, as well as get rid of the loose layer of rust. All this can be done with coarse sandpaper, a metal brush or a grinding machine. In the case where there are a lot of metal products or elements, a sandblasting apparatus is used.

The next step is degreasing. When cleaning new forged items, certain rules must be followed. So black metal products directly from the factory may have stains of oil or fatty nature. Also, various lubricants may remain on their surface. Under such circumstances, you can get rid of all this by using any solvent or 5% solution of synthetic detergent to flush. Metal products having a smooth and shiny surface require sanding paper P-40 or higher to remove dust.

Forged products coloring
In order to achieve aesthetic, reliable and wear-resistant painting, it is necessary to carry out all finishing work in dry and calm weather. Air temperature should be in the range from + 20 ° to + 36 °, and composition - not lower than + 16 °. Humidity parameters - from 40 to 85%.You also need to ensure that the direct rays of the sun do not fall on a coating that has not yet dried. The final layer of paint for forging is applied two hours after painting, although the time depends directly on the composition used. Corners and edges are painted most diligently, as they are most susceptible to corrosion.
There are several stages of painting forged products:
- The use of materials for the transformation of rust. After the corresponding composition has been applied, rust turns into a chemically neutral coating of a durable composition, as a result of which the anticorrosion properties of the primer composition are enhanced.
- Primer application. High-quality primer prevents rust, has high moisture resistance, promotes high adhesion with metal structures and further coating. The traditional primer has little resistance to wear and minimal decorative properties. But currently special three-in-one primer enamelsthat are able to provide the product with an attractive appearance and protect it from corrosion. The primer can be universal or specialized - for work only outside or only indoors. Therefore, you must carefully read the label when choosing soil.
- Stage of painting. Paint must be applied on top of the primer. It protects the surface from the negative effects of environmental factors, such as precipitation, sunlight, significant changes in temperature. In order to enhance protection and increase the wear resistance of paints, special varnishes can be used as an additional layer.
Thanks to modern technology, it became possible to combine the properties of all layers. For example, rust-transforming substances can be added to the primer layer, and components with an anticorrosive effect in the paintwork material.

Special compositions for forged products
Forged paint for forged coatings
After painting metal surfaces with a special composition, art forging acquires the necessary color and shade for this interior, and also the composition protects the coating from corrosion. There are several types of special blacksmith paints WS-Plast German production, which are some of the highest quality. Since they are made from acrylic binders, the service of their operation reaches 8 years. This paint material is applied to a different surface, even to an already painted one. But it is necessary to do a trial painting. In this case, the paint consumption is 125 grams per 1 m2.
From the blacksmith paints, another WS-Patina composition with the patina effect, which creates the effect of gold, copper or silver, should be distinguished. Also interesting is the Zinga coating, which is a ready-made composition on a solvent. Such a coating will contribute to the effective protection of the metal surface from physical and electrochemical factors, as well as from corrosion. Due to this, the wear resistance of the coating is more than 40 years, it all depends on the thickness of the applied composition. In addition, some companies offer the same alkyd based primer and paint, which are ideal for forged products.

Three-component paints
Recently, such special three-component paints have been developed when a rust transformer, a primer and a decorative coating are contained in one container. This allows you to apply the composition immediately to the rust, not forgetting to clean off its loose layer.Currently, such compositions are produced by both foreign and domestic manufacturers. The highest quality are the compositions of the company Hammerite. As a result of the fact that solvents evaporate very quickly from painted surfaces, art forged products dry in 60-90 minutes. Of the domestic manufacturers, the most popular can be considered paints from the manufacturer "NOVA".
The composition of this paint includes enamel with anticorrosive properties Novax on an alkyd basis and a two-component composition designed specifically for use in aggressive environmental conditions.
Thus, today on the market there is a wide range of paints and varnishes for forged gates or fences, as well as for other similar products. When applied correctly, these formulations will provide long-term protection of the metal from corrosion.
