Serebryanka is a finely dispersed aluminum powder that has a light gray steel shade. This material is used mainly for the preparation of paints. There are only two types of silver powder in powder - PAP-1 and PAP-2. Paint from them is prepared using different technologies. For information on how to dilute silver in one case or another, as well as how to properly apply it to the surface, read the article.
Powder composition
The only component of silver is the actual aluminum powder itself, made by crushing. The varieties of PAP-1 and PAP-2 differ only in the size of their constituent fractions. Powder PAP-1 is made from larger metal particles, and PAP-2 from smaller ones. At enterprises, this aluminum powder is made according to the standards stipulated by GOST 5631-79.
On sale today there is not only silverfish powder itself, but also ready-made PD paste. Use it whenself-preparation of paint is more convenient than PAP-1 and PAP-2. But it also costs more, of course. If desired, today you can also purchase ready-made paint based on silver. It is called BT-177.
How to breed silverfish: cooking pasta
To prepare such a semi-finished product from PAP-1, you will need a special heat-resistant varnish BT-577, and from PAP-2 - any. From PAP-1 silverfish, paste is made as follows:
- pour 2 parts of the powder into any suitable container;
- add 5 parts of BT-577 varnish to it;
- thoroughly mix the ingredients until a completely homogeneous paste is obtained.
Lacquer BT-577 is an excellent answer to the question of how silver is bred, if it is supposed to be used for painting surfaces that heat up during operation.
From PAP-2 powder, the paste is prepared as follows:
- pour 1 part of silver into a container;
- add 3-4 parts of any varnish to it;
- everything is thoroughly mixed.
Of course, in order to get a high-quality paste, you need to have an idea not only about what products should be added to the powder, but also about how to dilute silverfish correctly. In all cases, it is desirable to mix the components using a construction mixer. In this way, you can get a much more homogeneous, and therefore high-quality, paste. Mix the components manually for at least 10 minutes.
How to breed a silverfishdrying oil: proportions for PAP-1 and PAP-2
In addition to varnish, this tool can also be used to make paste. Moreover, both for PAP-1 powder and for PAP-2. But at the same time, it must be borne in mind that when using drying oil, a non-heat-resistant paste is obtained. It is allowed to use it for processing only ordinary, non-heating surfaces. For both types of powder, natural drying oil should not be used. It is better to take a synthetic version of it.
So, how to dilute silverfish with drying oil? The proportions for PAP-2 in this case will be 1x3 or 1x4. For the PAP-1 silver coin, this indicator is slightly different - 2x5.
How to make paint
After the paste is ready, it should be diluted to such a consistency that it is convenient to handle the surface. The answer to the question of how to dilute silver mixed with varnish or drying oil is quite simple. You can use for this purpose:
- various solvents;
- turpentine;
- solvent.
The proportions of paste and thinner in the preparation of paint depend on which tool is supposed to be used for surface treatment. To apply silver, like any other paintwork, an airbrush, brushes or varnish can be used. In the first case, the components are mixed in a 1x1 ratio. When using a roller or brush, the solvent takes half as much as the paste.
Ready-made purchased paint of this varietyhas a rather thick consistency. Therefore, the owners of country houses and apartments who decide to make repairs are often interested in how to breed BT-177 silverfish from a spray shop. In this case, it is also worth using a solvent. It is believed that its variety No. 646 is best suited for such paint. No more than 20% of the solvent can be added to the purchased silver BT-177. Otherwise, it will lose its original properties.
The color of silver-painted surfaces is quite presentable. However, if desired, you can give it some nice original shade. In this case, when answering the question of how to dilute silver paint, you should think about using special tint pigments.
Advantages and disadvantages of silverfish
The advantages of this tool primarily include:
- strong grip;
- long service life;
- fast drying;
- anti-corrosion properties;
- UV resistant;
- the ability to form an absolutely even layer without streaks and streaks;
- can be used on surfaces of different materials.
The answer to the question of how to properly dilute silver for painting is completely simple. This, of course, can also be attributed to the advantages of the BT-177. The advantage of this type of coatings is considered non-toxic after drying. But, of course, directly in the process of surface treatment with thisthe smell of varnish is still present. Therefore, painting BT-177 with closed windows and doors is not recommended. In addition, gloves should be worn on hands before starting surface treatment. It is also advisable to use a respirator.
The disadvantages of silverfish include:
- explosiveness of the powder itself;
- impossibility of application on surfaces covered with oil and alkyd paint, as well as nitro enamels.
The disadvantage of this tool is also considered to be that the surface treated by it gets dirty rather quickly and is poorly cleaned at the same time.
How to paint correctly
So, we figured out how to breed silver. Next, let's figure out how to use this tool correctly. Most often, BT-177 is used for painting metal or wood. Before processing, any surface must be cleaned of dust and dirt. From the metal, in addition, it is necessary to remove scale and rust. It is advisable to sand the tree before starting processing.
It is not necessary to prime the surface before using the silver. Coverage of this paint is already quite good. Apply BT-177, like any other coatings, in 2-3 layers. It is best to use a spray gun or roller for processing. Before applying each subsequent layer, you need to wait until the previous one is completely dry.
After painting the surface with silver, it should be additionally coated with the same varnish that was used to make the paste. In this case, it will servethe film formed by the agent is much longer.
Storage conditions
Of course, when performing repairs in an apartment or house, you should know not only how to dilute silverfish with drying oil, varnish and solvents. You also need to have an idea about how to properly store the resulting paste or paint. To prevent the product from drying out, a hermetically sealed container should be used under it. Silver can be stored in such containers for about 6 months. In the room where the container with paint will be installed, the positive temperature should be maintained all year round. Also, when storing BT-177 silverfish or paste, it should be borne in mind that these products are highly flammable. Therefore, keep them away from open sources of fire.
Conclusion
Thus, we have found out how silver is bred (powder for painting metal and wood). To prepare the paste, you should use varnish. Synthetic drying oil can also be used for this purpose. In order to make the paint itself, you should use a solvent. When preparing BT-177 on your own, you need to mix all the components as carefully as possible. In this case, the tool will turn out to be of the same quality as the one released at the enterprise.
