Materials (a part IV)

Limy structures apply for internal and external pokrasochnyh works on concrete, a brick, plaster, sometimes on a tree.

The Binding material in limy structure is slaked izvest which, besides, paints structure in white colour. For reception of other colour add colour pigments. It is necessary to mean that izvest can mix up only with shchelochestojkimi dyes (minium, soot, zhzhenaja a bone, ohra, a mummy, umbra, okis chrome, a sienna).

To check up a pigment on stability to alkali, it is necessary to put a few powder of a pigment in a glass glass and to pour its solution kausticheskoj soda. The unstable painting substance will instantly change colour.

For achievement of durability of limy structure in it add table salt, alum or drying oil.

At preparation cement water structure instead of to exhaust cement is used.

Glutinous (cretaceous) structures are used only for internal paintings of the surfaces plastered or revetted with dry plaster. These structures do not contain some alkali, therefore in them it is possible to add almost all pigments.

Silicate structures apply to furnish of the plastered, brick or stone facades. In premises colouring on a tree is possible.

These structures prepare from a dry ready paint, kalievogo liquid glass, get divorced water.

In silicate structures add only shchelochestojkie painting substances.

Silicate paints are strong enough, hygienic, do not fade from solar beams. They form a transparent film with matte shine with which it is possible to wash with water.

However water painting structures, despite the advantages, have essential lacks: they are short-lived, from them it is difficult to receive identical coverings on colour.

To to waterless painting structures carry oil paints, enamels, varnishes.

Oil paints . Binding substance and simultaneously a thinner in oil paints is drying oil. These paints apply both for internal, and to external works.

Oil structures happen ready to the use or gustotertymi (them it is necessary to plant with drying oil).

Paints package in banks on which there are labels with instructions of appointment of a paint, the colours, an applied thinner, etc.

For external pokrasochnyh works the oil paints containing proof pigments and binding substances, steady against a bright sunlight are suitable: beige, pale-yellow, under an ivory, blue, light blue, grey, yellow, green, pistachio, red, red-brown.

At colouring of internal surfaces apply the same paints, as for external, and, besides, salad, is pale-salad, dark blue, light-grey-blue, light-turquoise, brown, light-beige, light-sand, rozovo-beige, light grey, a Bordeaux.

Enamel paints prepare on oil and synthetic varnishes by introduction in varnishes is thin the pounded pigments. At drying they form the firm, brilliant layer reminding enamel. Them apply to colouring of the metal, plastered and wooden surfaces as in premises, and outside.

Enamels provide a high-quality covering of the surfaces which are exposed to atmospheric influences, located in places with the raised humidity.

There are enamels of different kinds, marks and colouring. Let out enamels ready to the use, with instructions of a way and area of their application.

Varnishes are solutions of natural or artificial pitches in various solvents. Depending on containing solvent varnishes are subdivided on oil (vegetable oil), skipidarnye, spirit (ethyl spirit), alkidnye, nitrocellulose, poliuretanovye, etc.

In painting works are used oil-pitch and bezmasljanye synthetic varnishes. Them apply to a covering on an oil paint, a tree, metal as in premises, and outside.

Oil, enamel paints and varnishes provide more durable, waterproof covering of a facade, and also rich colour possibilities and high aesthetic qualities.

At manufacturing emulsionnyh paints knitting materials get divorced special emulsijami, consisting of drying oil, glue and alkali. Pigments for these paints plant with water. These paints are not neither oil, nor enamel, glutinous. Their structure includes the smallest particles of plastic in regular intervals weighed in water. .

The Surfaces painted by these paints, pass steams of water and air, that is "ф№°р=". Besides, it is possible to wash them.

For internal coverings these paints replace with themselves glutinous.

By the Industry are issued vodoemulsionnye paints for external and for internal works.

At external furnish of buildings vodoemulsionnymi structures it is possible to paint concrete, brick, plastered, wooden and other porous surfaces, and also the grounded metal. Having added a pigment, it is possible to receive a paint of the necessary colour.

For colouring of a facade of the wooden house, cheap and hygienic Swedish and Finnish emulsionnyj painting structures are more durable. In comparison with oil paints they in one and a half time serve longer, several times more cheaply. The house painted by these structures, "ф№°ш=" and thus does not pass a moisture. Before painting it is not required preliminary ogruntovki. At repeated colouring of the house by the same structures it is enough only obmesti a wall a rigid broom (in zachistke the old paint is not present necessity). .

The Swedish structure: 1160 g torments (rye or wheaten), 520 g iron kuporosa, 520 g table salt 520 g a dry limy pigment, 480 g natural drying oil and about 9 l of water.

Limy pigments concern: minium iron (red-brown colour), ohra (yellow), zhzhenaja ohra (brown), okis chrome (green), synthetic cinnabar (red), a synthetic mummy (red-brown), a natural mummy (brown), brown mars (brown).

At first prepare from a flour and water (6 paste: a flour fill in with a small amount of cold water and stir. In the received dough add cold water before reception of a consistence of liquid sour cream. The water which has remained from 6 l boil and add boiled water a continuous squirt in the received weight, intensively stirring slowly. Paste filter (that there were no lumps) then put on fire. Then into hot paste pour salt and kuporos and mix before their full dissolution. After that put in a hot solution a pigment and carefully stir. In the received structure a thin stream pour in drying oil at constant stirring. Then add the remained hot water (nearby 3), well mix to a painting consistence. .

The Swedish structure is considered the best as it includes drying oil.

The Finnish structure: 720 g torments, 1560 g iron kuporosa, 360 g table salt, 1560 g a dry limy pigment and water about 9 l.

This structure prepare the same as also Swedish. .

It is better to wrap up the Prepared structure, that during all operating time it was warm. To prepare a paint it is necessary in such quantity which can be used during 1-1,5 business hours. After this time the structure gets denser, therefore it is necessary to add in it hot water that reduces its durability.

Prepare both structures in the enameled ware, and for work cast from it necessary quantity in suitable plastic banks. .

Swedish and Finnish structures are suitable for painting and the plastered surfaces, but in this case the colour choice is limited. Without a pigment these paints have yellowish colour because of containing in them iron kuporosa. For reception of brighter colour structure it is possible to add manganese peroxide, ohru or a chalk with soot.

Now in specialised shops there is a wide choice of the domestic and foreign paint and varnish production ready to the use and allowing to reach high decorative and hygienic qualities of furnish of the house, and also auxiliary materials for painting works: first coats, shpatlevok, glues, solvents, etc. This production is supplied by detailed instructions about appointment, properties and a way of its application.
