Colouring by various structures
(A part 2)

Colouring by enamel structures. These paints also put brushes. Skilful performance of works gives the chance to receive exclusively smooth, as though a smooth surface. The structure of enamels includes the pitches which are getting denser at low temperature. The thickened enamels lay down on a surface a thick layer which drying up screws up the face. Therefore enamels are good for applying warmed up.

For heating ware with enamel put in hot, and it is even better in boiling water. Nagretuju enamel carefully mix, that it was absolutely homogeneous both for structure, and on temperature. It is necessary to warm up to 60... 80°С. Some enamels prepare on flying solvents. Them warm up only in the closed ware, observing thus fire-prevention rules because solvents are explosive. Under colouring by surface enamels prepare in the same way, as well as under oil colouring.

Enamels let out both for drawing by brushes, and for mechanical dispersion. For work as brushes enamels for mechanical dispersion because from them solvent quickly disappears are unsuitable, and they badly spread on a surface, leaving rough strips.

Some enamels produce on the basis of synthetic pitches. For such enamels of a surface before colouring do not demand proolifki, but only drawing of a special first coat of factory manufacturing or the first coats prepared on a place of works from the same enamel, dissolved to the necessary density corresponding solvent.

the Covering of the painted surfaces a varnish. the surfaces Painted by oil paints cover with oil varnishes to add to them shine and to protect from destruction.

All varnishes including oil, incorporate pitches which during cold time get thick and lay down rough strips. Varnishes should be warmed up the same as also enamels, it is good to stir and only after that to put by means of a brush on painted by an oil paint and well dried surfaces. Put a varnish a thin layer for one or two times. Repeated varnishing carry out on well dried out first varnish coat.

Application of a safety guard at colouring of covers Colouring of covers, platbands, doors, plinths. At covers especially carefully it is necessary to paint corners because there there are admissions more often. A put paint or enamel shade lengthways bruskov cover. The paint should reach glasses. Traces of a paint from glasses after drying delete a chisel or a sharp knife. However not to paint over some glass, it is better to apply special guards (fig. 91). Them produce from a tin, a roofing steel, a cardboard or plywood in length no more than 25 the Working parties at plywood and cardboard guards see cut off on a facet that they were sharp and under them does not remain not painted over places.

Covers after colouring should be left opened on two days that the paint has completely dried up in places pritvora.

Painting doors, a paint at first put across, i.e. On width of a door, and then there and then shade on its height. Work can be carried out brushes or platens. At colouring of platbands a paint shade on their length.

Switches, sockets etc. Before colouring it is better to remove not to soil their paint.

Painting plinths, it is necessary to be careful not to soil a floor and walls. Here too it is convenient to use safety guards.
