How and what is better to dilute silver powder, proportions and rules of application

The name suggests that the paint contains silver. In reality, there is no precious metal in the composition, and the powder is named silver for the silver color of the painted surface. The dye is still popular, it forms an even coating, is suitable for use inside and outside the building, and protects the material from corrosion and weathering. To obtain a paint with the listed qualities, it is necessary to dissolve the powder well.

Composition and characteristics of silver

Serebryanka in undissolved form is aluminum powder produced by grinding aluminum scrap. The powder has an intense silver color that gives the paint its name. A colorant can be added to the composition to paint the surface like gold or bronze while maintaining an intense metallic luster.

A bituminous varnish and a synthetic drying oil are generally used to dissolve the powder. Depending on the dissolving component used and the grinding degree of the aluminum scrap, the powder is divided into 2 types: PAP-1 and PAP-2. Each type is intended for painting specific surfaces, it is operated under certain conditions.

The maximum lifespan of surfaces painted with heat-resistant silver is 7 years outdoors and up to 15 years indoors, without loss of decorative quality. With constant exposure to moisture, it decreases to 3 years.

How to properly plant with your own hands

It is necessary to prepare for work, to protect the skin from dye penetration. The worker must dilute the powder while wearing closed clothing and rubber gloves. A respirator is necessary to protect the airways so that no aluminum powder particles enter the lungs. If silver gets on your skin, immediately wash the stained area with soap and water.

To dilute the powder, take a container that you will not hesitate to throw away, because you will not be able to wash the silver out of it. You also need to take a solvent to adjust the thickness of the paint. Turpentine, white spirit and solvent are suitable.

To protect surrounding surfaces from accidental stains, cover with newspapers or film. If during operation the drops fell in the wrong place, they are immediately washed off with solvents suitable for a specific material. You can use vegetable oil, smear drops with it, leave it for 10-15 minutes, then the wipe with effort with a dry cloth. A nail polish remover is also suitable, but it should not contain acetone or it will damage the surface.

To dilute the silver powder, a dissolving component is poured into it slowly, stirring continuously. You need to stir until the substance becomes homogeneous. It takes about 15 minutes, stirring by hand. To speed up the work, you need to use a construction mixer. The work is done outdoors. It is also possible indoors if it is well ventilated.

After mixing silver powder and varnish or drying oil, a dense and viscous solution is obtained. Coloring is problematic for them. Therefore, to achieve the optimum consistency, any of the above solvents are added to the composition.

How to dilute with flaxseed oil

Drying oil is less expensive than heat-resistant varnish. But silver, diluted with this composition, does not have the same protective effect as paint with varnish, does not withstand exposure to high temperatures. To dilute the aluminum powder, only synthetic drying oil is used.

A silver composition for painting is prepared by the following step-by-step method:

1. Take a container for mixing and a tool that will be used for painting (spray gun, brush or roller).
2. Put on personal protective equipment.
3. Pour silver powder into the container.
4. Pour in the drying oil. This is done slowly, while gently stirring the resulting composition with a wooden stick until it acquires a homogeneous viscous consistency. If you have a construction mixer, use it. This not only speeds up the work, but also allows you to get a more uniform mass.
5. A solvent is added to the resulting paint in a ratio of 1: 5. This ratio is optimal for serebryanka and drying oil. It provides a paint that easily adheres to the material, does not spread and forms a dense coating.
6. The painted surface is left to dry.

The disadvantage of silver, dissolved with linseed oil, is that it dries for a long time, unlike varnish paint. It takes up to 3 days to wait for the coating to be completely dry.

Recommended proportions for PAP-1 and PAP-2

Different types of silverware are diluted in unequal proportions. The following ratios are considered optimal:

1. PAP-1 is diluted with linseed oil in a ratio of 2: 5. The resulting thick composition is diluted with "solvent" or an analogue.
2. PAP-2 can be combined with both types of diluents. The proportion of powder and thinner is 1: 3 or 1: 4. Both proportions create a dense mass that is not suitable for easy painting of surfaces. The most commonly used solvent is turpentine. The amount of added substance is determined taking into account the tool with which the material will be painted. If with a roller or brush, silver and solvent are taken 1: 0.5, if with a spray gun, then in equal proportions.

After adding the solvent, the composition is carefully and slowly stirred so that it becomes uniform and forms a high-quality coating.Prepared liquid paint is stored less than powder - only six months. The shelf life of silver powder is almost infinite.

Dilution of silverware with metal varnish

The general principle for diluting aluminum powder with heat-resistant varnish is the same as for drying oil. But it is necessary to take into account certain rules of breeding in order to obtain a reliable coating of metal surfaces exposed to high temperatures.

In a hardware store, you need to buy a varnish marked as heat-resistant. Usually buy BT-577 polish. Silver and thinner are taken in a ratio of 2: 5. The powder is poured into the container, then the varnish is slowly poured in, constantly stirring the mass until it acquires a uniform consistency.

Heat-resistant varnish has a pungent smell, so you should work in a respirator even when outdoors. If the work is carried out indoors, ventilation must be ideal.

Advantages and disadvantages of using silver

Serebryanka is used to cover a wide variety of domestic and industrial installations. It creates a stable and durable coating not only on metal, but also on wood and concrete. The heat-resistant paint is applicable for coating radiators, heaters, hot pipes. Cold pipes, elements of industrial devices and mechanisms, and bridge structures are often painted with the usual composition.

Silver is particularly sought after, due to its resistance to moisture, in the shipbuilding industry. It covers the structures of shipyards, shipyards, ships.

No other paint so reliably protects ship elements from negative external factors: moisture, weather conditions, corrosion.The protective effect of aluminum paint lasts approximately 3 years. The painted surface is smooth and even, the silver luster is not intense, the ship structures are aesthetically pleasing and neat.

The popularity of silverfish is due to many positive qualities. Dye:

• lays flat on surface when painting with any tool;
• resistant to temperature fluctuations and mechanical stress;
• environmentally friendly, does not contain toxic components;
• dries in a short time;
• has a long shelf life;
• suitable for painting all materials, all construction objects;
• looks attractive, forms a silver coating without a single flaw.

Silver, like any coloring composition, also has disadvantages:

• the powder is explosive, improper storage may cause a fire;
• it is unacceptable to apply silverware to an alkyd coating, the second composition under the first swells, bubbles, as a result, the surface is deformed;
• do not apply aluminum paint on a galvanized product, when joining metals, the risk of corrosion increases.

Rules and features of applying silver paint

After dissolving the silver powder, you can start painting. It is necessary to work in a room with excellent ventilation. For work you need to take a painting tool. Serebryanka copes well with a roller, brush and spray gun.

Before painting, the surface must be prepared. The work is carried out in stages according to the following algorithm:

1. Remove rust and old peeling paint using sandpaper or a wire brush.Grinding must be done carefully, otherwise poorly removed old paint will cause new peeling. The wood is also treated with sandpaper. Lime and chalk coating is removed from brick and concrete surfaces.
2. Apply a primer to improve adhesion. A layer of soil is sufficient, since silver has good adhesion to the material. A primer for concrete and brick surfaces is recommended. It is necessary if the old paint layer has eaten away, it was not possible to grind it.
3. The silver layer is applied in a thin layer on a dry surface. Apply 2 or 3 coats: the next one after the previous one is completely dry. It is necessary to work quickly, especially with a brush, because the process of hardening of the coating is short. For the same reason, the wait between coats does not take long. If you slow down, the paint will have time to dry, and continuing to work with a brush will create flaws on the surface.

If the money is divorced correctly, it is not difficult to work with, the coating turns out to be high-quality and aesthetically pleasing. To prolong the life of the silver coating, you can apply a protective varnish over it, the same one that was used to dissolve.
