Structures of first coats, % on weight:

  1. bitumen - 40, soljarovoe oil, kerosene or automobile gasoline - 60;
  2. 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.
