Preparation of painting structures (a part 3)

structures are much stronger than Emulsionnye glutinous, but is much weaker than the oil. Replacing oil structures at colouring in premises, they reduce cost of colouring and save drying oil. At oil colourings indoors it is possible to replace a drying oil part with cheaper thinners - emulsijami.

It is simple in manufacturing emulsionnyj K.A.Ivanov and S.T.Dementyev's thinner. Its application gives the chance to lower the expense of drying oil on 30-50%, and gustotertyh oil paints on 15-30%. An emulsionnyj thinner prepare from to exhaust-kipelki or the limy test, salt and drying oil (natural or oksoli) as follows. In 10 l of water where add 100 g table salt, extinguish 1 kg to exhaust-kipelki (salt accelerates clearing process). During clearing a mix carefully mix and leave slaked izvest on 2-3 sut that it has settled on a bottom. From above the transparent solution named alkali which merge in pure capacity (without traces is formed to exhaust), and add on each litre of the merged alkali 50 g is thin the sifted chalk, receiving so-called suspension. (The chalk is necessary that alkali easily mixed up with drying oil.)

To Receive alkali it is possible and from the limy test, for what 1 ch. The test fill in 3 ch. Waters, carefully mix and leave for upholding on 3 ch. A transparent alkaline solution merge and add a chalk in such quantity as it is specified above.

For reception emulsii or emulsionnogo a thinner in suspension a squirt pour in drying oil, carefully mix during 10-15 mines and receive homogeneous smetanoobraznuju the weight painted in cream or yellow colour depending on colour of added drying oil.

Emulsionnyj a thinner № 1: natural drying oil - 25% (0,25), suspension - 75% (0,75).

Emulsionnyj a thinner № 2: drying oil-oksol - 35-45% (0,35-0,45), suspension - 55-65% (0,55-0,65). On such emulsionnom a thinner it is possible to prepare structures for proolifki and ogruntovki.

Emulsionnyj structure for proolifki: emulsionnyj a thinner - 820 g, a pigment - 10 g, turpentine-170

Emulsionnaja an oil first coat: emulsionnyj a thinner - 400 g, gustotertaja an oil paint - 50-100 g, turpentine - 100

Prepare these structures in such sequence. In emulsionnyj a thinner add a pigment (dry) or gustotertuju an oil paint for podtsvechivanija, carefully mix and only after that add solvent - turpentine. The received structure stir to the necessary density and filter.

Proolifka this structure, or emulsirovka, is carried out usually. At first on a surface there is a light foamy touch which through 5-6 ch disappears, and the surface assumes a usual air. Through 30 ch emulsionnaja the film dries up and it is possible to start to shpatlevaniju or to colouring of a surface by an oil paint.

Oil-emulsionnaja shpatlevka: emulsionnyj a thinner - 500 g, 10%-s' glutinous solution - 500 g, a chalk - 2-2,5 kg.

Prepare shpatlevku so. In emulsionnyj a thinner pour in a squirt a glutinous solution, carefully and quickly mix to homogeneous weight. After that in the small portions add a chalk, all again carefully mix, receiving shpatlevku the necessary density which can be applied for shpatlevanija walls, doors and covers in buildings.

Painting structure on emulsionnom a thinner: emulsionnyj a thinner - 600 g, gustotertaja an oil paint - 400

In gustotertuju an oil paint add emulsionnyj a thinner and carefully mix to homogeneous structure. Depending on density of a paint the quantity emulsionnogo a thinner can decrease.

At colouring by the mechanised way on 1 l of a paint add 125-180 g turpentine. If koler prepare from dry pigments, emulsionnogo a thinner take 70% and drying oils of 30%, mix them and gradually pour there at careful hashing a pigment.

In that case when it is necessary to prolong service life of oil colouring on emulsionnom a thinner, it cover with an oil varnish which shine also adds to it. The painted surfaces before a covering it is delicious well dry: in the summer - not less than 6 sut, in the winter - 12 that from an oil paint all flying substances negatively influencing durability of a varnish film and its shine have evaporated.

Swedish and Finnish structures. Limy and glutinous structures are of little use for colouring of external wooden surfaces because term of their service no more than one season as they are quickly washed off by rain water.

Long check has shown that for this purpose the most suitable are emulsionnye structures from which it is considered the best Swedish. Swedish and Finnish structures are suitable and for colouring of the plastered surfaces, but their colour is rather limited. Without the additive of a pigment they because of presence iron kuporosa have yellowish colour. However, some variety can achieve, having replaced minium ohroj, a chalk with soot or peroksidom manganese.

the Swedish structure: any drying up vegetable oil (linen, konopljanoe) or drying oil - 240 g, a rye flour - 580 g, iron kuporos - 260 g, table salt - 260 g, iron minium or a mummy - 260 g, water (to working density) - about 4,5 l.

From a flour and 3 l of water prepare in the usual way paste. In the presence of lumps it filter. In the received paste, without removing it from fire, pour kuporos and table salt, and boil a mix at constant stirring before full dissolution of crystals. After that pour minium or a mummy and again mix. Then in the received structure at careful hashing by small portions pour in oil or drying oil and mix until the homogeneous weight with which dilute with water of demanded density will turn out. It is recommended to make use of the prepared structure there and then; as even at short storage it starts to get denser and demands water addition that reduces its durability a little.

For colouring of 1 m 2 is required to a wooden surface nearby 200-300 g structure.

the Finnish structure: a rye flour - 120 g, iron kuporos - 260 g, table salt - 60 g, minium iron or a mummy - 260 g, water (to working density) - about 1,5 l. Prepare as well as the Swedish structure, only paste prepare from 1 l of water, instead of from 3.

Oil structures apply to external and internal works on plaster, a brick, a stone, concrete, a tree and metal. Paints ready to the use need to be mixed carefully only before application. Gustotertye paints demand addition of drying oil and careful hashing. Drying oil enter in the small portions.

As though well have mixed a paint, it should be filtered through a fine sieve to remove probably remained clots. The filtered paint spreads is better and more exactly lays down.

The White paint consisting of whitewash and drying oil to prepare simply, it is more difficult to make difficult koler. For this purpose it is necessary to mix two-three paints. All of them should be preliminary finished to a working condition and are filtered. Prepare oil structures in the same sequence, as well as glutinous. For colour definition necessarily it is necessary to make vykrasku on a piece of plywood, a cardboard, a tin.
