Features of application and color of hammered effect paint, top-4 formulations
Enamel or hammer paint is a popular decorative type of painting materials. It is a composition that gives the surface a refined appearance of carving or grained leather. It is mainly used for painting objects, objects and metal products. The coating is a durable film that protects the metal from moisture and corrosion. It is characterized by a long period of protection.
Distinctive features of hammer painting
This is a decorative type of paints and varnishes, which, after being applied to the surface, form a coating similar to embossing or stamped metal (bronze, gold, copper). Hammer painting is generally used to paint metal objects, objects and forged products. The cover looks like real currency. It seems that the surface was deliberately beaten with a hammer, hence the name - hammer enamel.
The outwardly colored base is somewhat reminiscent of an orange peel. After application, the metallic hammer effect paint does not spread on the surface but foams forming numerous bumps. Hammer enamel has a more viscous consistency.It contains polymer and metallic components that give it strength and metallic luster.
Apply to surface using short nap roller, brush or spray gun. The size or pattern of the embossment depends on the method of applying the paint materials. To obtain a uniform and uniform coating, it is advisable to use a paint gun.
Key Features of Hammer Painting:
- is a one-component paint material;
- used mainly for metal;
- creates a durable coating;
- can be used for interior and exterior work;
- prevents corrosion of metals;
- after drying, forms a semi-gloss film with a hammer;
- dries in 1-2 hours, cures in 72 hours;
- diluted with a solvent recommended by the manufacturer;
- applied in 2-5 layers;
- is distinguished by low consumption (150 grams per square meter);
- the coating can withstand temperature drops from -60 to +60 degrees Celsius.
There are several types of hammered enamel (depending on the constituents): alkyd, acrylic, epoxy, nitrocellulose. The most durable is epoxy. The most popular are alkyd hammertone paints.

Advantages and disadvantages
Varieties
Hammered effect paints and varnishes are available from a variety of manufacturers. All these paints have one thing in common: they form a durable coating that is resistant to moisture and corrosion.
EP-1323ME
It is an epoxy enamel that includes the properties of paint, primer and rust remover. Mainly used to paint steel and cast iron objects, objects.
ML-165
It is a melamine enamel (with alkyd resins) for painting metal objects, which is diluted with xylene. It can be used for installations operated under adverse weather conditions.
NTs-221
It is a nitrocellulose enamel that is used for decorative painting of objects and metal objects. Applicable for interior work only. It is applied to the surface by pneumatic spraying. Thinned with Thinner 646.
Hammerite
Well-known Hammerite compositions are among the most expensive paints and varnishes. They are used for painting metal objects, objects. Can be used on rust.
Surface preparation before painting
Before painting, it is recommended to clean the old or previously used surface from loose rust, crumbled old coating, and also degrease it with a solvent (white spirit). Hammer paint goes well with any paint. The only exceptions are powder and bituminous compositions.
It is recommended to completely remove old powder or bituminous coatings from the surface. Chemicals are usually used to wash them. There are other ways to remove powdered dyes (baking, sandblasting or water jet).
New metal products (factory only) should be cleaned of factory grease before painting.The articles are washed with a solvent (solvent, white spirit). Surface treatment is carried out two or three times. At the very end, the base is wiped with acetone.
It is advisable to grind smooth or shiny surfaces with sandpaper or an ordinary wire brush before painting. It is important to create a slight roughness. Grinding increases the adhesive qualities of the paint.
How to apply the paint
In order to create the most decorative coating, it is important to choose the right tool. Usually, manufacturers indicate how to apply the paint with a hammer to the metal.
Brush
For painting, use the highest quality brushes (flute with natural bristles). It is not recommended to use tools with synthetic fibers (the material can melt).
Before the main coloring, the corners, elbows and seams are first painted. The paint is applied with longitudinal or transverse movements in two or three layers.
As a rule, brushes are used for painting surfaces with bends (for wrought iron gates, products) and in the case of a small amount of work. For a flat and wide base, such a tool is not used, since after painting the scratches of the brush will be visible. Optimal coverage is no more than 100 microns.
Roll
It is advisable to use such a tool (short-haired, furry or woolen) for wide horizontal surfaces. When applying paint with a hammer on a vertical base, the paint may run. For painting, do not use a foam roller. The chemical constituents of paint and varnish materials will corrode this porous material. Using a roller, the surface is painted in two or three layers.
Aerosol
It is advisable to use a spray can for painting only with a small amount of work. The spray is used to repair or renew enamel with a hammer in a small area. It is recommended to shake the can well before painting. It is desirable to spray at a distance of 18-28 cm from the surface. The paint is carried out in 2-4 layers.
Using a pneumatic gun
To apply the enamel with a hammer in a thin and even coat, it is recommended to use a pneumatic gun. It's important to remember that there are metallic flakes in the makeup of hammer paint, so choosing the correct nozzle size is important. It is recommended to pre-filter the paint.
When working with a pneumatic tool, it is advisable to keep the nozzle perpendicular to the surface to be painted.
The spray gun is used for painting garage doors, metal roofs, gates. The paint material is applied to the surface in 3-5 layers. Between each application, take a break to completely dry the paint.
Spray
The best finish is obtained with a pneumatic gun. The surface must be dry, clean and smooth before painting. Using this tool requires certain skills.
The main thing is to choose the right degree of viscosity of paint materials. For this purpose, the type of thinner specified in the instructions is added to the enamel. To check the readiness of the paint, use a viscometer or determine the viscosity with the naked eye (the composition should not flow from the stirring paddle, but slowly drip). The surface is painted quickly and accurately. It is desirable in 3-5 layers.
Additional tips and tricks
It is advisable to use hammer painting materials for the repair and restoration of objects and metal objects.This paint hides dents and cracks. In addition, it protects the metal from corrosion. You need to work with such paint as quickly as possible. The paint hardens and dries quickly. Before painting, the object must be positioned horizontally so that the paint does not flow. In the vertical position, it will not be possible to obtain a pebble effect.
