Besides, the industry lets out following mastics: bitumno-rubber izoljatsionnuju "Ђчюы" bitumno-skipidarnuju "…шёъш" cold bitumno-synthetic, kumarono-rubber КН-2 and КН-3, "¤хЁьшэшф" "+ѕьш-ыръё" on which labels there are instructions on their application. All of them are produced with application of materials which are not always accessible to the mass builder.
However there are mastics which well paste linole-minds and tiles, and materials for their preparation are available on sale.
Lakomelovaja mastic prepares from an oil-pitch varnish № 7 (40%), dry tonkomolotogo a chalk (60%) by mixing of materials among themselves. That the mix has turned out homogeneous, it is desirable to grind it on kraskoterke or to wipe through a fine sieve. Mastic is applied to gluing alkidnogo linoleum and should be used during 7 ch. Hardens at a room temperature in 3-5 days
Lakosurikovaja cretaceous mastic prepares from an oil varnish № 74, 75 or 408 (35-30%), dry ohry (3-5%), iron minium (2-5%) and dry tonkoprosejannogo a chalk (60%). It is applied to gluing linoleumov on a fabric underlying cause. Mastic prepare so. A chalk, ohru and minium carefully mix among themselves. In this mix pour in a varnish and again carefully mix, it is desirable to grind in addition also a mix in kraskoterke. 2-3 days the Thickened mastic plant viability of mastic with a varnish.

Structures of first coats, % on weight:
- bitumen - 40, soljarovoe oil, kerosene or automobile gasoline - 60;
- a coal pitch - 45, antratsenovoe oil - 55.
The Measured materials heat up to full raspravlenija and the foaming terminations, deleting emerging impurity. Fire extinguish, cool bitumen or a pitch to 80°С, pour in solvent and all carefully mix.
The Prepared first coat should be liquid and homogeneous (without lumps). Is better to filter it through a fine sieve. After drawing on the dry basis it should dry up for 5-10 ch without otlipa.
To Store first coats it is necessary in tight ware. However is better to prepare a first coat directly ahead of application.
