What to breed "silver" (powder)? Serebryanka: instructions for use

Repair is expensive, but, unfortunately, not very long-term. But you want the fresh coating to last as long as possible. Most modern materials can not boast of such properties. Then the proceeds come to old, time-tested funds. For example, powder "silver". Such a coating is widely known for its wear-resistant properties, resistance to environmental influences.

In this article, we will talk about the amazing properties of this material and learn how to prepare "silver" from the powder at home.

What is "silver"

This wonderful tool would rather be called "aluminka." In spite of the beautiful name, there is not a drop of silver in its composition. The powder consists entirely of fine aluminum and the waste of this material. Simply put, the powder "silver" - is milled in the dust aluminum. That's why it has such a beautiful silvery hue.

To obtain a coloring composition "silver" (powder) is bred to the desired consistency by special means, which we'll talk about below. The mixture obtained in this way is widely used for coloring various surfaces.

If you do not want to bother, you can buy a ready-made paint in the store or on the market and use it for the intended purpose. However, in this case, you run the risk of catching the tricks of thrifty manufacturers. Such grandsons do not hesitate to add a variety of additives to the paint, reducing its cost, but adversely affecting the quality of the material.

Types of "silver"

Since the powder "silver" completely consists of aluminum powder, then there is only one difference - a fraction. There are two types of "silver" on the market:

• PAP-1 - aluminum powder of a larger fraction;
• PAP-2 is the smaller particles of this metal.

The difference lies solely in the size of the fraction, all other properties are identical.

Differences have already finished "silver" (paint). The powder is diluted with varnish or linseed oil. Depending on what kind of a tool is used, the finished paint can have different properties. For example, when diluted with a heat-resistant varnish, the mixture can withstand temperatures of up to 400 ° C. Such paint is allowed to be applied to radiators, car engines, the internal surface of fireplaces and other surfaces that are exposed to high temperatures.

If such properties are not necessary, then the bituminous varnish BT-577 will suit the preparation of the paint.

Where to use "liquid silver"

Powder "silver" - a fairly popular material and is widely used in everyday life, and at production facilities. Silvery paint is used for staining:

• Bridges;
• Details of production departments;
• Radiator systems and district heating batteries;
• Ship parts, floating stations and docks, port and underwater structures;
• Various pipes and metal elements;
• Parts of systems that must be protected from overheating;
• Sculptures, monuments, grave fences, souvenirs and other items.

Benefits

The wide application of this paint and varnish product is due to its positive properties. Here are just some of the advantages of this paint:

• It covers the surface, like a second skin, lies flatly and fairly thinly;
• "Silver" can cover almost all types of surfaces: wood, metal, ceramics, concrete, plastic and others;
• The coating is absolutely not susceptible to rust, does not exfoliate and does not peel, stuck to the surface;
• Can be resistant to high temperatures;
• Itself is non-toxic and very quickly dries up;
• In comparison with other dyeing materials, "silver" has a huge service life: 3 years under water, 6-7 years in the open air, more than 10 years indoors;
• Painted in silver, the materials look rather original and attract attention.

disadvantages

Before we breed "silver" (powder) for painting metal and other surfaces, let's talk not only about the advantages, but also about the shortcomings of this material. They are few:

1. Dry powder is quite explosive, so it is worth keeping it away from fire, in a tightly closed container. Also it is worth keeping silver powder away from children.
2. Silver paint can not be applied to surfaces previously painted with oil, NBH or alkyd paints, as well as nitro-enamel. Bubbles can be observed on such surfaces when the "silver" is applied. The paint falls off badly or completely disappears.
3. Contrary to advertising, the acrylic "silver" not only does not have all the remarkable properties of the usual paint, but also lets rust traces at the time of staining.
4. A solution of silvery aluminum powder can not be used for painting galvanized parts. From the contact of these two compounds, the zinc coating quickly collapses. If the need for galvanizing is too great, cover it with a pair of special primers.

Preparation of "silver"

So, how to dilute the powder "silver" for painting? Before you start, you need to stock up on everything you need. You will need:

• Rubber gloves and goggles;
• Brushes or spray gun;
• Capacity for breeding (keep in mind, wash it will not work);
• Solvent for paint: "White Spirit" or something like that;
• Linseed oil or varnish.

If it is necessary to prepare ordinary, non-heat resistant paint, varnish and aluminum powder are mixed in a ratio of 1: 3. That is, one part of the powder has three parts of varnish or varnish. If the mixture obtained is too thick, the desired consistency can be achieved by adding a little turpentine, "Solvent" or "White Spirit". In cases where the resulting mixture will be applied with a paintbrush or roller, it is worth adding a little to the solvent. In order to use the spray gun, the mixture must be diluted in a ratio of 1: 1.

If you want to get a heat-resistant paint, you will need a varnish that has these properties. Dilute the mixture as follows: two parts of an aluminum powder and five parts of a heat-resistant varnish. Olifa in this case is not good.

Now we should dwell a little more on the process of mixing:

• Varnish must be poured into small quantities in powder (not vice versa);
• That the mixture turned out without lumps, it should be continuously stirred for at least 15-20 minutes;
• It is best to use a construction mixer.
• If the finished solution is too thick, you can achieve the desired consistency with the help of toluene.

Attention! As any varnish is quite toxic and has a pungent odor, the mixing process must be carried out in a well-ventilated area, protecting the respiratory system with a respirator.

How to apply the paint correctly

To make the painting process as good as possible, the surface must be prepared: cleaned of rust, scale, dust and dirt. The wooden parts must be thoroughly ground and wiped with a damp cloth to remove fine shavings. If you remove the old paint is not possible, the surface should be sanded and covered with a primer.

Depending on the desired result, it is best to apply the paint in several layers, usually two or three. Work needs to be done fairly quickly, since a thin layer of paint dries out quickly in the open air. If you hesitate, the "silver" withers directly on the brush and it will have to be thrown away.

How to clean everything around

Now you know what interesting properties are "silver" (powder). How to dilute this material, you also already understood. But that is not all. Quite often when working, droplets of silver paint fall on those surfaces where they should not be. What to do in this case? How to remove "silver" after it dries?

If you diluted the powder at home, then to remove unwanted droplets and streaks, you need to use the same solvent that was used in the preparation of the mixture.

In the case when the ready (shop) paint was used and the solvent is unknown, you can try to apply well-known folk methods:

1. Apply on the stain liquid for removing female nail polish, which does not contain acetone. After a while, rinse the dissolved paint with plain water.
2. Densely spread the silver stain with any vegetable oil. Wait 10-15 minutes and rub the paint with a dry, hard cloth. Repeat the process several times until the desired effect is achieved.
