Mastic is used when carrying out roofing works, such as:

  • sealing of seams, joints and adjunctions;
  • local repair of mastic and rolled roofs;
  • gluing of rolled materials.



  • reliably protects a roof from leakages;
  • does not burst at low temperatures;
  • it is steady against high temperatures;
  • quickly dries after drawing;
  • does not demand a warming up, it is easily put with a brush or the roller;
  • it is made of high-quality raw materials;
  • high durability of coupling with surfaces from concrete, reinforced concrete, a brick, metal and a tree,
    with materials on a bituminous basis;
  • conforms to requirements of GOST 30693-2000 "Mastics roofing and waterproofing".




Waterproofing NeoMast mastic – the unicomponent bituminous and polymeric structure completely ready to application. After polymerization represents a rubber-like elastic membrane of black color.


Instruction for application:

To perform works at a temperature of air from -10 °C to +50 °C. Working temperature of mastic has to be not below +15 °C.

Preparation of a surface
To clear the processed surface of dust, oils, a rust and other pollution, and also of free water, snow and frost. To dry and warm up a surface up to the temperature not less than -10 °C.

Preparation for use
Before drawing carefully to mix mastic with use of the electric drill (power not less than 0,5 kW with a possibility of adjustment of frequency of turns) with a nozzle for hashing of construction mixes with a diameter no more than 12 cm. 
For convenience of application mastic dilution by solvents (toluene, white spirit, gasoline) to the necessary consistence, but no more than 20% of the mass of mastic is allowed. The same solvents are recommended to be used for cleaning of tools.

Performance of work
To apply mastic with a rigid brush, the pallet, the roller or method of dispersion under pressure. The recommended thickness of one layer – 2 mm in the dry rest. Putting mastic by a filling method with the subsequent leveling is possible. In a hot sunny weather to apply mastic with layers no more than 0,5 mm thick for 4 – 5 passes, whenever possible to shade the venue of works.

Average consumption of mastic

For creation of a layer 0,5 mm thick makes 0,5 l/sq.m. 




Mastic use is not allowed:

  • in premises and in contact with drinking water;
  • in liquid organic environments: oil, oil products, solvents;
  • for gluing of heat-insulating materials on the basis of polystyrene.



Metal tin of 2 l, metal eurobuckets of 5 and 21,5 l.
