How to paint forged products, 3 suitable compositions and rules of application
Curly metal elements look exquisite, they are used in the form of decorative figures, fences and gates, on the facades of buildings to fence balconies, and in the interior to decorate stairs. The disadvantage of structures is the appearance of rust, and in order to protect the surface from corrosion or give it a new color, it is necessary to paint forged products. To exclude regular maintenance of the structure, it is necessary to choose the right protective composition.
What you need to know about painting forged products
To preserve the structures, it is necessary to respect the surface preparation technology and to choose a paint that will correspond to the conditions of use in terms of temperature, humidity and resistance to mechanical abrasion.
The most vulnerable place in the structure is the weld seam, where, due to exposure to moisture, rust spots form and the metal begins to crumble. Scratches and improper treatment of the structure during manufacture also lead to loss of coating strength and rust, which corrodes the surface.
Appropriate blacksmith paints
Enamels for metal are divided into two categories - these are compositions for interior and exterior.The first should be environmentally friendly and not emit harmful substances during operation, the second should be weatherproof, tolerate temperature extremes, moisten well and not fade in the sun. The best choice would be a universal metal paint with anti-corrosion additives in the composition.
Molotkovaya
Three-component paint for metal structures that do not have a perfectly flat surface. The heterogeneous structure of the composition with a thick consistency well hides irregularities.
It is applied in two layers. The drying time of the paint is 2 to 4 hours, depending on the air temperature.
Black-smith
Composition specially developed for metal, based on polymers. When applied, the paint creates a durable coating with a lifespan of 25-30 years. After drying, it forms a smooth texture with a glossy surface. It is applied by spray gun, roller and brush.
It is applied in one layer. Drying time is 20-30 minutes regardless of air temperature.
ML
Refers to automotive enamels that are resistant to mechanical damage and weathering. Creates a uniform glossy finish on the surface.
It is applied in two layers. Drying of the coating is carried out in chambers at a temperature of 80 degrees for 2-3 hours.
Coloring rules
The service life of the coating depends on compliance with the technology. This is especially true for outdoor decorative figures, fences and gates.
Before painting forged products, you need to carry out preparatory work:
- Cleaning the surface from rust and old composition. You can use a wire brush or sandpaper.
- Dusting and degreasing of the structure.
- Application of a primer with anti-corrosion additives on the surface.
- Coloring of a forged product in 1-2 layers.
When performing work, it is necessary to wear protective equipment. The paint releases harmful substances until it dries completely, which is dangerous for health.
How to paint antiques
For the decoration of the structure, manufacturers offer varnish compositions with "patina" particles of gold or silver color. When applying such a coating, the service life of the paint increases and the effect of antiquity is created, which is in good harmony with the black, brown and dark gray color of the structure.
Choosing the right paint for forged products, you can create a unique interior inside the house and transform the territory of the site.
