Painting forged products - how to paint correctly

Painting forged products - how to paint correctly Do-it-yourself painting of forged products

Since ancient times, metal has been one of the most important materials, and both in production and in domestic conditions. At the same time, despite the strength, reliability and a very long service life, even metal structures can be exposed to a negative environmental factor.

A forged product is a different metal structure that is assembled by any method from individual elements. These include different types of gates, fences, gates, railings on stairs and balconies, as well as many other products.

Before painting with them, the surface must be primed.

Moreover, you can use paint and varnish material and primer in tandem.

General information

Thanks to the artistic method of forging, metal objects can be made not only practical, but also aesthetic. All this helps to make art forging an ideal option for interior and exterior decoration. But under modern conditions, it is the painting of forged products with your own hands that is the best method for preventing corrosion, due to which their operational life is increased.

Special preparation of metal products before painting

Painting forged products - how to paint correctly Initially, it is necessary to carry out the primary treatment of metal surfaces, and only then should the paint and varnish material be applied.

If forged products have been under the direct influence of environmental factors for a long time, then a lot of attention will need to be paid to their preliminary processing. Thus, you should remove the paint, which has already begun to flake off, and also get rid of the loose layer of rust. All this can be done with coarse sandpaper, a sander, or a metal brush. In this case, when there are large quantities of metal products or elements, a sandblaster is used.

The degreasing process

So, the second stage will be degreasing.

When cleaning new forged items, be sure to follow certain rules. So black metal products directly from the factory can have grease or oil stains. Various lubricants may also remain on their surface. Under similar circumstances, this can be eliminated by using any type of solvent for rinsing, or a 5% solution of a synthetic detergent solution. Metal products that have smooth and shiny surfaces require sanding with P-40 or higher sandpaper to remove dust.

Please note that in this case, zinc surfaces are washed off under a huge pressure of water, and at that time they will not be cleaned with aluminum at all, they are simply degreased.

Painting forged type products

In order to achieve a reliable, beautiful and wear-resistant painting, it is necessary to carry out all finishing work in calm and dry weather ... The air temperature should be within + 20 .

.. + 36 degrees, and the composition should not be lower than +17 degrees. Humidity parameters should be between 40% and 85%. So you should make sure that direct sunlight does not fall on the coating, which has not yet had time to dry.

The final coat of forging paint is applied two hours after coating, although the duration will directly depend on the composition used.

Edges and corners should be painted with the greatest diligence, because they are most susceptible to corrosive effects. There are several steps to painting forged items:

  1. Applying materials to transform rust. After such a composition has been applied, the rust will begin to transform into a chemically neutral coating of the composition with high strength, as a result of which the anti-corrosion properties of the primer are enhanced.
  2. Applying a primer.

    Before painting forged products, it is required to use a high-quality primer, which prevents rust, and has a high resistance to moisture, promotes a high degree of adhesion to metal structures and the future coating. Traditional priming has low wear resistance and minimal decorative properties. But at the moment, they are producing special "3 in 1" primer enamels, which can provide the product with a beautiful appearance and maximally protect against corrosion. The primer can be universal or special - for work only outside or only inside the room / building. For this reason, the label should be read carefully when choosing a primer.

  3. Staining step - the paint should be applied over the primer layer. It will protect the surface from the aggressive influence of environmental factors, namely precipitation, sunlight, large temperature drops. In order to enhance protection and increase the degree of resistance of paints to wear, special varnish compositions can be used as an additional layer.

It is thanks to the latest technologies that the ability to combine layer properties has appeared. For example, a transforming rust substance can be added to the primer layer, and components that have an anti-corrosion effect can be added to the paint and varnish composition.

Thus, the combined paint and varnish material for forging for tens of years gives products made by the forging method, efficiency and at the same time increases their service life, protecting them from negative corrosion effects.

Specialized compositions for dyeing forged products

Consider all compositions in more detail

Blacksmith paints and varnishes for forged coatings

After painting the metal surface with a special composition, artistic types of forging acquire the shade and color required for this interior, and the composition will also protect the coating from corrosion. There are several varieties of German-made WS-Plast special forging paints and varnishes, which are among the highest quality. Since they are made from acrylic binders, their service life reaches 7 years. This paint and varnish material is applied to different surfaces, even already painted over.

However, a test staining should be done. In this case, the consumption of paint and varnish material will be 0. 125 kg per square meter.

Painting forged products - how to paint correctly Of the blacksmith-type paints, one more composition should be distinguished, namely WS-Ratina, which has a patina effect and creates effect of copper, gold or silver. Even more interesting will be the Zinga coating, which is a ready-made solvent-based compound.

Such a coating will contribute to the effectiveness of protecting the metal surface from electrochemical and physical factors, as well as from corrosion. Thanks to this, the resistance to wear of the coating will be more than 40 years, and it all depends on the thickness of the applied agent. Moreover, certain companies offer primers and paints on the same alkyd base that are ideal for forged products.

Three-component paints and varnishes

Recently, special three-component paints and varnishes have been invented, when in one container there is a primer, rust and decorative coating transformer. This will make it possible to apply the composition immediately over the rust, without forgetting to clean its loose layer.

At the moment, such compositions are made by both domestic and foreign manufacturers. The best quality are the compositions from the Hammerite company.

As a result of the fact that solvents evaporate quickly from painted surfaces, and forged art forged products dry out in 1-1. 5 hours. Of the manufacturers of domestic type, the most popular are NOVA paints.

This paint contains Novax enamel with anticorrosive properties based on alkyds and a two-component composition, which is specially designed for use in aggressive environmental conditions. So, at the moment on the market there is a huge selection of paints and varnishes for gates made by forging or fences, as well as for other similar products. When applied correctly, these formulations provide long-term corrosion protection to the metal.
