Serebryanka is called finely dispersed aluminum powder, which 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 various technologies. Read about how to breed silverfish in a particular case, as well as how to apply it to the surface correctly.
Powder composition
The only component of silverfish is the aluminum powder itself, produced by crushing. The varieties PAP-1 and PAP-2 differ only in the size of the fractions included in their composition. PAP-1 powder is made from larger metal particles, and PAP-2 is made from small ones. At enterprises, this aluminum powder is made according to the standards provided by GOST 5631-79.
On sale today there is not only silver powder itself, but also ready-made PD paste. It is more convenient to use it for self-preparation of paint than PAP-1 and PAP-2. But at the same time it costs, of course, more expensive. If you wish, today you can buy ready-made paint based on silverfish. It is called BT-177.
How to breed silverfish: cooking pasta
To prepare such a semi-finished product from PAP-1, you need a special heat-resistant varnish BT-577, and from PAP-2, any. From PAP-1 silverfish, the 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 components until a completely homogeneous paste is obtained.
BT-577 varnish is an excellent answer to the question of what silverfish are bred in case it is supposed to be used for painting surfaces that are warming up during operation.
From PAP-2 powder, the paste is prepared as follows:
- pour 1 part silverfish into the container;
- add to it 3-4 parts of any varnish;
- all mix thoroughly.
Of course, in order to get a quality paste, you need to have an idea not only about what products should be added to the powder, but also about how to breed the silverfish correctly. In all cases, mixing the components is desirable using a construction mixer. Thus, you can get a much more uniform, and, consequently, high-quality, paste. Manually mix the components for at least 10 minutes.
How to breed silverfish with drying oil: proportions for PAP-1 and PAP-2
In addition to varnish, this agent can also be used to make paste. Moreover, for both PAP-1 powder and PAP-2. But at the same time, you need to keep in mind that when using drying oils , 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 breed silverfish with linseed oil? The proportions for PAP-2 in this case will be 1x3 or 1x4. For PAP-1 silverfish, 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 treat the surface. The answer to the question of how to breed silverfish mixed with varnish or varnish is quite simple. You can use for this purpose:
- various solvents;
- turpentine;
- solvent.
The proportions of the paste and solvent in the preparation of the paint depend on which tool is intended to be used for surface treatment. For applying silverfish, like any other paintwork, spray guns, brushes or varnish can be used. In the first case, the components are mixed in a proportion of 1x1. When using a roller or solvent brush, take half as much as paste.
Ready-made paint of this variety has a rather thick consistency. Therefore, the owners of country houses and apartments, who decided to make repairs, are often interested in how to make silver BT-177 from a spray store. In this case, it is also worth using a solvent. It is believed that its type No. 646 is best suited for such paint. No more than 20% 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 you wish, you can give it some pleasant original shade. In this case, when answering the question of how to dilute silver paint, it is worth considering the use of special tinted pigments.
Advantages and disadvantages of silverfish
The advantages of this tool primarily include:
- strong adhesion to the surface;
- long service life;
- quick drying;
- anticorrosive properties;
- resistance to ultraviolet radiation;
- the ability to form a completely even layer without streaks and stains;
- the ability to use on surfaces of different materials.
The answer to the question of how to properly breed silverfish for painting is completely simple. This, of course, can also be attributed to the advantages of BT-177. An advantage of this type of coatings is non-toxicity after drying. But, of course, directly in the process of surface treatment with this tool, the smell of varnish is still present. Therefore, BT-177 staining 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;
- the impossibility of applying to surfaces coated with oil and alkyd paint, as well as nitro enamels.
The minus of this tool is also considered to be that the surface treated by it is rather quickly contaminated and at the same time poorly cleaned.
How to paint
So, how to breed a silverfish, we have found out. 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 metal, in addition, it is necessary to remove scale and rust. It is advisable to polish the tree before the start of processing.
Priming the surface before using silverfish is optional. The hiding power of this paint is already quite good. Apply BT-177, like any other paintwork, should be 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 staining the surface with silver, it should be additionally coated with the same varnish that was used to make the paste. In this case, the film formed by the tool will last much longer.
Storage conditions
Of course, when performing repairs in an apartment or house, one should know not only how to breed silver with varnish, varnish and solvents. You must also have an idea about how to properly store the resulting paste or paint. To prevent the product from drying out, use a hermetically sealed container under it. In such containers, silverfish can be stored for about 6 months. In the room where the container with paint will be installed, the 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, they should be kept away from open sources of fire.
Conclusion
Thus, we have found out why silverfish is bred (powder for painting metal and wood). To prepare the paste should use varnish. Synthetic drying oil can also be used for this purpose. In order to make the paint itself, a solvent should be used. With the independent preparation of BT-177, mix all the components as carefully as possible. In this case, the product will turn out to be of the same quality as the one released at the enterprise.
