How to dilute paint for collapse?

The paintopult is a special device that allows you to quickly and evenly apply the LKM. However, it is impossible to pour into it the undiluted viscous paint, and therefore the issue of breeding LKM remains fairly relevant.

What do you need to breed enamel?

The color of the surfaces with the help of pulverizers makes it possible to get even and beautiful coverage, deprived of defects and leaps, as well as significantly reduce the execution date of painting works. However, not all LKMs are suitable for working with a sprayer due to very high viscosity.

  • Too thick enamel is difficult to evenly apply on the surface, She will start to bed with a thick layer and will dry long. This will significantly increase the flow rate of the LKM and time painting.
  • Undiluted paint is not able to effectively fill the pores and penetrate the narrow slits, which markedly affects the quality of work.
  • Modern paintopulizers are quite sensitive technique and quickly clogged from too thick LKM. Most domestic models are equipped with a diameter with a diameter of 0.5 to 2 mm, which are difficult to spray dense enamel. As a result, they have to constantly disassemble and clean the internal channels. By the way, when working with large professional pulverizers, the diameters of the nozzles of which reach 6 mm reach 6 mm, there is another problem – too liquid enamel will be divided into large drops and to form herds on the stained objects. Therefore, before proceeding to the dilution of the LKM, it is necessary to get acquainted with the technical characteristics of the collapse.

How to breed different colors?

In order to properly distribute enamel, you need to get acquainted with the instructions on the bank. Typically, the manufacturer indicates which solvent should be used and in which amount to add it. It must be remembered that for each paint material, you must use your dilution tools. But sometimes it happens that information on the bank is written in a foreign language or the text is poorly visible or chosen paint. In such cases, it is necessary to use the advice of experienced masters, the recommendations of which are presented below.

Acrylic enamel

These two-component paints created from ester polymers are used for work on wooden, drywall and metal surfaces.

For dilution it is better to use tap or distilled water.

Alkyd

These one-component LVM are produced on the basis of alkyd resins and after drying requires a lacquer coating. Alkyd enamel is used to work on concrete, wooden and metal planes, as well as primer with anti-corrosion properties. It is inexpensive, quickly dries and does not fade in the sun. In the role of a diluent, you can use xylene, turpentine, white spirit, solvent “NEFRA-C 50/170” or a mixture of these substances.

Nitroemali

The basis of these paints is the nitrocellulosic varnish, connected with coloring components. Nitroemali used for painting metal objects differ in rapid drying and sharp odor.

You can dilute them with White spirit, xylene and solvents No. 645 and No. 646. You can also use gasoline and solvent.

Water-emulsion

The water disposal is the cheapest LKM and is made of polymers, coloring agents and water. Used in all types of repair and painting works. During dilution, it is allowed to use the ether, alcohol or distilled water. It is not necessary to dilute in conventional water from under the tap, as it is because of a low quality and a large number of impurities, it often becomes the appearance of white raid on painted planes.

Oil

At the heart of such paints is the connection of olifes and coloring pigments. Oil enamels are distinguished by bright, juicy colors, which is often used as facades when repairing and building housing. There are varieties intended for metal work. Such enamels are in their composition lead Surik and are enough toxic.

For dilution of oil paints, you can take the White spirit and Pinen or use Skipidar.

Molotkovy

LVM data have a porous structure and are represented by persistent polymer dyes dissolved in a chemical reagent. They are often used to process metal, very durable and skillfully mask surface defects. Dilution of hammer paint requires toluene or xylene.

Rubber

Such paint is often used as a facade, and it also paint metal structures, metal tile, straightening, slate, plasterboard, chipboard, fiberboard, concrete, plaster and brick. To dilute it takes distilled water, but only no more than 10% of the total volume.

Diluted rubber paint required to stir regularly.

How to make up?

Dilute the LKM for the sprayer at home is easy. This requires you to select the appropriate solvent, strictly observe the proportion and stick to the simple algorithm.

  1. Initially, it is necessary to thoroughly mix the paint in that bank in which it was purchased. To do this, you can use any tool with a vopotoxy ending capable of getting to the bottom of the bank. Mix the enamel until the lumps and clots remain in it, and in its consistency it will not begin to resemble a thick sour cream. Similar way, you need to mix the paint in all banks that are planned to be used for painting. Then the contents of all cans are required to merge into one large capacity and move again.
  2. Next, it is recommended to rinse the empty cans with solvent and drain into the total capacity of the residues. It is necessary to do this, as a sufficient number of LKM remains on the walls and the bottom, and if you do not collect it, it dries and thumps together with banks. It is very important to remember that when using expensive branded enamels, breeding should be carried out by solvents of the same brand as LKM.
  3. Then proceed to the most important event – adding solvent. Pour it with a thin jet, continuously stirring the paint. From time to time you need to raise the tool to be mixed, and look at the flowing enamel. Ideally, paint should flock smoothly unintended jet. If it drips with large drops, this means that the enamel is still very thick and needs a solvent additive.

Professional builders determine the consistency of paint “on the eye”, and for less experienced masters, a simple device is invented – viscometer. On domestic samples, the unit of measurement are seconds, which is very convenient and understandable even those who face the device for the first time. The viscometer is made in the form equipped with a container holder with a volume of 0.1 liters. At the bottom of the case there is an opening of 8, 6 or 4 mm. Budget samples are made of plastic, and metal is used for the manufacture of professional instruments.

To use this device is very simple, for this you need to perform the following actions:

  • Close the hole with your finger and fill the paint tank;
  • Take the stopwatch and run it, setting the finger from the hole synchronously;
  • After all the paint runs out with a flat ridge, you need to turn off the stopwatch.

Only the time of leakage of the jet is taken into account, it is not necessary to count. The result is checked with a table, which is included in the buckleter kit, and determine the viscosity of the enamel.

If there were no tables at hand, you can use the following data, which are valid for the instrument having a hole of 4 mm:

  • The norm for oil paint varies from 15 to 22 s;
  • For acrylic – from 14 to 20 s;
  • for water-level – from 18 to 26 s;
  • For alkyd compositions and nitroemals – 15-22 with.

Viscosity is required to be measured in the temperature range of 20-22 degrees, since at a more reduced temperatures, the LKM thickens, and at higher – it becomes fat. The cost of viscometer varies from 1000 to 3000 rubles., And you can buy the device in any construction store.

After the desired consistency is obtained, a slightly solvent is poured into the paintopult, which was used when diluting the LKM, and the tool is blown over 2-3 minutes.

It must be done in order to dissolve fatty or oily spots inside the collapse, which can remain there from the previous painting and be incompatible with the new paint. Then the dilute enamel is poured into the working tank of the painting and check the quality of staining. The composition should evenly exit the nozzle and spray in a fine stream.

If the LKM crashes with large splashes or drops, then a slightly solvent is fascinated to the tank, mix well and continue testing. With an ideal correction of enamel and solvent, the air mixture comes out of the nozzle directed fog and the uniform layer falls on the surface. Sometimes it happens that when applying the first layer, enamel formed a beautiful and smooth layer, and when spraying the second – it became “shaggy”. So it happens with fast-circuit compositions, so before applying the second layer, you need to conduct control testing and, if necessary, add a little solvent.

What to do if the solution is too liquid?

If the paint has become much fat after dilution, than it should be, then a series of measures should be taken to return to it more thick consistency.

  • Add undiluted enamel from banks and stir carefully.
  • Give liquid enamel to stand 2-3 hours with an open lid. The solvent begins to evaporate, and the LKM quickly thickens.
  • Put the container with liquid enamel in a cold place. Reduced temperature will force the material quickly thickening.
  • When using enamels of white colors, you can pour into them a small amount of chalk or gypsum and mix well.
  • Use the paintopult with a nozzle of a small diameter and thus apply several layers at once.

    Properly selected enamel viscosity will help to significantly unload the paint and will not make it work on wear. This will increase the service life of the pulverizer and makes the color of fast and high-quality.
