Painting metal and plastic in gold, brass and bronze | Types of gold paints and 4 ready-made solutions for painting

It is difficult to imagine any premises in a complete form without installed interior or entrance doors that provide a security barrier, heat retention, and prevent the spread of unwanted sounds. It is worth remembering that in past times and now it is one of the main elements of the design of any interior. Currently, solutions related to filling the room with the spirit of antiquity in retro or country styles have become popular, which involve the use of appropriate design of all elements, including door leaves with fittings, regardless of the material used in their manufacture.

A room with an antique metal door

What you need to know about paint

When deciding to independently design a metal door to look like antique bronze, you need to confidently navigate the method of preparing metal for the procedure, paints, and methods of proper application.

First of all, it is necessary to remember that metal products are dependent on the influence of external factors, the main one of which is moist air, which contributes to the formation of corrosive destruction. Metal paint is primarily intended to prevent such exposure. Secondly, modern paint compositions give the metal surface any color, durable protection, and if antique paint is used with the technique of “aging” the metal, it gives the appearance of almost any material suitable for the interior of a particular room or building.

To paint metal surfaces, paint and varnish mixtures are used, including organic solvents (such as white spirit and the like), as well as synthetic resins. During the drying process, they form protective paint films with characteristics of high density and strength. Such paints are used for processing metal elements in interior spaces, located on the outside of buildings and on streets.

For a long time, blacksmiths tried not to use coloring on their products to preserve the individual characteristics of handmade work. But modern paints, produced by manufacturers specifically for processing such products, make it possible to give the product additional elegance and originality, imitate almost any metal, cause a visual effect of aging, while providing reliable, long-term protection against corrosion. But it should be noted that the cost of such a coating is significant, but the price of forging is comparable.

How to paint a chrome part

Chrome parts are a rather controversial element of car decor, due to its obvious garishness. Many car enthusiasts consider themselves ardent opponents of chrome parts and try in every possible way to camouflage such decorations of car manufacturers by covering them with film or painting. Those who are comfortable with chrome are also often forced to mask the decor due to scratches or cracks on it. Yes, chrome plating is not a particularly durable coating and often rubs off or even swells on radiator grilles, which looks very unflattering.

Tools and accessories

Carrying out painting work on any surface, including metal, requires the prior acquisition and preparation of the required number of devices and special accessories.

To prepare the surface:

Which is better: heated floors or radiators?

Warm floorBatteries

• metal bristle brush,
• sandpaper of various sizes,
• possibly an angle grinder,
• drill with special attachments for cleaning metal,
• if it is necessary to remove old paint - a hair dryer and scrapers,
• rags.

For applying primer paint and varnish coatings:

• paint brushes of various widths, hardness and sizes,
• artistic brushes (if delicate works are required),
• various types of rollers,
• foam elements,
• It is possible to use a painting console.

1. Paints and varnishes and solvents.
2. Accessories in the form of various containers and more.

Important! Work on painting surfaces and elements should be carried out in a well-ventilated area or outdoors to avoid poisoning from fumes of paints and solvents. At the same time, compliance with fire safety rules must be ensured: exclusion of sources of fire, smoking and the possibility of sparking.

Powder production

The production of powder takes place using industrial methods by repeatedly crushing bronze powder. After several stages of grinding, its separation is carried out in ball mills or pneumatic units.

Paints and varnishes based on bronze powder have significant hiding power. The quality of painting depends on the size of the fraction. The highest quality is powder, which, when sifted, forms a residue of no more than 1% (on sieve No. 0.045). To obtain a powder with maximum coverage, it is necessary to use bronze alloys rather than pure copper. With one gram of such powder you can cover up to 4500 cm² of surface.

Method of painting metal surfaces bronze

Painting metal surfaces bronze has been used for decades, but due to the unpleasant odor and poor resistance to temperature conditions, the possibility of use was limited. Modern paint mixtures based on acrylic and water have expanded the scope of application. They are characterized by resistance to operating temperature conditions, exceptional resistance to corrosion, and do not create discomfort when painting room elements.

Important! Any work related to the processing of metal products is associated with the possible formation of chips, which can harm human skin. At the same time, contact with exposed areas of the body by chemical compounds, including paints and varnishes, can lead to burns.

Thus, when carrying out the work listed below, it is mandatory to use protective clothing, headgear and goggles.

Currently, the following procedure is used when painting bronze:

1. Applies to all types of surface painting. It is necessary to prepare surfaces for painting by removing old paint, rust, etc. using suitable equipment.
2. Mandatory degreasing is carried out.
3. To improve the quality of adhesion and create additional anti-corrosion protection for the material, the surface is primed.
4. After drying, apply a layer of bronze paint. After drying, the procedure is repeated until the desired visual effect.

We paint chrome products

Chrome is a modern, practical material that looks great and is not prone to corrosion. Things coated with this metal look stylish and interesting, but, unfortunately, tastes change and it is quite possible that a chrome chair will need to be repainted matte black to match the surrounding interior. Also, old things with a chrome plating damaged by time often need painting - by applying paint to them, you can get very attractive products that will become a real decoration of the interior. How to paint a chrome-plated item at home, using improvised materials and the most common acrylic or latex paint?

Antique bronze coating of metal

To give the product the appearance of an antique item, it is necessary to carry out the following sequence of procedures:

1. Preparation of the product for painting remains unchanged.
2. We apply the painting technique described earlier.
3. Natural irregularities with depressions must be treated with patina to the required percentage of darkening.
4. After drying, use a brush to glaze the corners with light paint, creating the effect of wear and tear from aging.
5. Finish by applying a thin layer of varnish.

Bronze with aging effect

To obtain the effect of old bronze, a technique using a craquelure primer coating is often used, which as a result gives the product a look with traces of rust, which ultimately represents the illusion of an old material.

Procedure for painting parts

The process of working with chrome is quite long, but you need to be careful and perform priming according to the following scheme:

• Remove the chrome part from the car using a flat tool, depending on the case, it can be a flat-head screwdriver or a clip-on clip.
• Rub the surface of the chrome with sandpaper until a matte effect appears. Sometimes, if the chrome is already pretty cracked, you can remove the chrome coating using a knife or the same screwdriver. It will come off in small pieces that resemble foil.

Repainting Chrome Nameplates
You can use Scotchbrite to matt all glossy surfaces. This should be done very carefully and “wet”, since any glossy area, even the smallest one, can cause the paint to crack and peel off.

A sufficiently matted chrome surface will resemble aluminum, with hints of copper visible in places. This surface can then be painted by performing preliminary priming.

• Then the part must be washed very well and dried perfectly, then apply a degreaser.
• If your part is not completely, but only in fragments, covered with chrome, then the next step is to apply a primer for plastic parts coated with chrome. Read the instructions carefully and follow the manufacturer's instructions - shake the can for a minute, then spray an even layer, wait 5 minutes until it dries and repeat application. It is very important not to get on matted chrome. Leave to dry for 15-20 minutes.

Please note that it is impossible to completely remove the chrome film from the part manually; all you can achieve at home is to grout the chrome to a matte state. This is necessary to increase adhesion, which will prevent the paint from peeling.

In addition, it is advisable to use a phosphating or acid primer, since it can penetrate quite deeply into micro-scratches in chrome. We have a separate article about acidic soil - acidic soil for a car.

Design errors

Unfortunately, it is not uncommon for a product to have a significant amount of time and money spent on aging, but it has an unfinished, and often contradictory, look to the era of imitation. The reasons include poor training of the person who carried out this work, violation of recommendations on the methodology and sequence of work, and may only consist of a careless attitude to detail. For example, painstaking work was carried out and the metal doors were painted in an antique style, but the frame did not undergo any changes, the fittings and small door parts have a modern design. The overall picture is not original, but rather unpleasant. If we consider the issue more deeply, then it is important to involve several elements of the overall interior of the room in the architectural group to create the effect of an ancient component.

A variant of the technique for making an antique door leaf is demonstrated in the following video.

Why is it important to carefully follow the preparatory steps?

Regular paint practically does not stick to chrome. If the dyeing technology is violated, it is very difficult to achieve an aesthetically attractive effect. In addition, the work may be in vain - the paint is simply washed off under the pressure of water.

To enhance the effect of the primer, you can first place the faucet parts in a special acid primer. This solution eats into the deeper layers of the metal and ensures reliable adhesion. Then proceed in the same way as in the previous version: apply a primer to protect the surface from corrosive processes, paint it in the chosen color.

Features of working with chrome-plated parts

During preparatory work and during the painting process, difficulties may arise with removing chrome, which is best rubbed with a special machine. Manual work will require diligence and a large supply of free time.

If you decide to transform the appearance of your car yourself and replace boring chrome parts with beautiful coal-black ones, then you should be patient and use high-quality materials. This process is quite lengthy, especially if you have to remove chrome from plastic yourself, but by following our recommendations, you will be able to do this job efficiently, and the effect will last a long time.

Aging materials

You can achieve the effect of aged metal by using the main method - aging through the creation of a patina and the formation of abrasions. Patina is applied with special paints, but for metal, acrylic-based metallic compounds are more often used. In stores today there is a wide range of such paints; in addition to their decorative function, they also perform a protective function.

There is a choice of acrylic paints for aged metal, namely:

Thanks to modern technologies, an aged effect can be given not only to metal surfaces. Often this painting is performed on plastic, wood and plaster products.

The aging process is completed by applying a final protective layer. For this they often use:

• acrylic-based varnish, which has a high degree of gloss;
• very durable polyurethane-based varnish with a gloss level of up to 50%;
• polyurethane-based varnish with a matte effect.

Application of coloring compounds

Before painting metal bronze, it should be prepared.

Applying paint and varnish material to unprepared areas will not produce results.

Careful surface preparation is required to remove traces of dirt and rust. If you apply paints and varnishes to areas damaged by corrosion, this will not protect the metal from premature destruction.

Preparatory work

Rust and remnants of old paint must be removed from the metal surface. To carry out such work, the following methods are used:

1. Rough mechanical cleaning with a wire brush or abrasive disc mechanisms.
2. Sandblasting. The advantage of this method is penetration into hard-to-reach areas. The downside is the relatively high price of the unit.
3. Cleaning surfaces with chemical compounds that react with rust and old paint. At the end of it, everything can be easily washed with a soft cloth.

When carrying out this work, you will need protective equipment to protect your face and hands from damage by small particles and reagents (goggles, gloves made of thick cotton fabric and a respirator).

After cleaning operations, a primer is applied to the prepared surfaces (in two layers). This improves the adhesion of the metal surface. At the same time, an additional moisture-proof polymer coating is used. Once the top coat of primer has set, you can begin applying the bronze dye.

Painting

Depending on the type of dye, it is applied using one of the methods to form a monochromatic coating. To do this you need:

1. dilute the mixture in water in the proportion described in the instructions;
2. prepare working brushes for painting small parts and surfaces in hard-to-reach places;
3. When painting flat areas, use a regular roller.

For these purposes, you can use a dye sold in cans with a spray gun.

When painting you need to pay attention to the nuances:

1. To obtain a more saturated color, after the first layer has dried, you will need to apply another one.
2. For streaks and stains, it is necessary to evenly blend the composition over the surface.

The bronze composition can be used to paint stainless steel to give a noble appearance. Bronze acrylic dyes are suitable for these purposes. They are environmentally friendly and durable.

Precautionary measures

• Do not insert a pin or other objects into the canal. Pressurized cylinder. Protect from direct sunlight and heat above 50°C. Do not pierce or burn even after use. Do not spray near open flames or hot objects. Do not smoke while working. Cylinders may only be thrown into designated areas.
• FIRE HAZARD! Flammable vapors. Keep away from heat, sparks and flame. VAPOR MAY CAUSE SPONTANEOUS COMBUSTION. Extinguish all fire sources and burners, turn off stoves, heaters, electric motors and other sources of ignition while spraying. Prevent fumes from accumulating by opening all windows and doors to create drafts.
• May cause dizziness, headaches, nausea, and irritation to the eyes, skin, nose, and throat. Wear eye protection, chemical resistant gloves, protective clothing and a respirator.
• Avoid contact with eyes. If contact occurs, rinse eyes with plenty of water for at least 15 minutes. Do not take orally. If swallowed, consult a physician. Avoid getting vapors into the respiratory tract. Ensure good ventilation during application and drying. If you experience difficulty breathing, watery eyes, or headaches, increase the flow of fresh air. Wash your hands thoroughly after work.
• Keep away from children!

Patination colors

On different metal surfaces, completely different color schemes can be achieved by patination. The most common patina color is greenish, which is produced by the oxidation of copper. On other metal surfaces, the resulting shade may be completely different:

• Rich yellow or ocher color on steel surfaces.

• Chocolate brown on brass and bronze items.

• Dark gray on silver items.

The choice of dry patina for metal work is quite varied. Powder is sold in almost every hardware store. Most common colors:

• aged silver;
• natural or oxidized copper;
• red gold.

Brighter radical colors are also available, for example, blue, lilac, red, allowing you to achieve an original effect on the surface of various metals.

Painting chrome parts

The next step is to apply a coat of paint, during which it is very important to paint all the gaps. The paint should dry for 5-10 minutes between coats of application. There should be 3-4 layers of paint in total.

Half an hour after applying the last coat of paint, spray the surface with varnish. It must be applied with very light movements from a long distance, since it is more liquid than paint and can cause drips that are almost impossible to remove. Apply it in two layers, taking a break of 15 minutes. Leave all this to dry for at least a day, after which the part can be returned to the car body.

Choosing the right solution

For a long time, any bronze paint had an organic solvent in its structure. Its presence contributed to the spread of an unpleasant specific odor, which significantly limited the scope of such solutions.

Nowadays, thanks to technological progress, water-soluble mixtures containing natural metal pigments have appeared. Acrylates act as binders in such solutions.

Water-based bronze paint (do not be confused - this is not Zinga conductive paint)

Acrylic bronze paint for metal has many advantages:

• Ecological cleanliness and absence of any unpleasant odors. During the drying process, only water vapor is released.
• Relatively low price. Using H2O as a base makes it much cheaper to produce, for example, oil analogues.
• Stunning non-ferrous metal appearance. It is also possible to apply it using the “antique” method, which will create an even greater natural effect.

Bas-relief surface painted in bronze shades

• Easy to use with your own hands. The application technology is not much different from using conventional paint and is quite feasible for an amateur.

Applying the solution using a brush

• Moisture insulation. Qualitatively protects metal from rust.

Tip: pre-applied Z inga electrically conductive paint will maximize the protection of iron from corrosion, as it will create a reliable thin-film galvanizing layer.

• High resistance to mechanical stress and ultraviolet radiation. For many years this finish will have its original appearance.
• Long service life. With proper use, at least ten years.

Advice: if there are many fire-hazardous items in the room, it is recommended to additionally use fire-retardant metal paints Polistil. They have the ability to foam when a fire occurs, preventing its further spread.
