Mastic bitumen BITELAST - ROOFING Ecobit bucket 20 kg DSTU B V.2.7-108-2001, Dnipropetrovsk region.

Mastic bitumen BITELAST — ROOFING Ecobit DSTU B V.2.7-108-2001 (GOST 30693-2000) Installation of a new roof, repair of an old one (together with roofing material and bituminous coating or in combinations with it), coating waterproofing of foundations, walls, for sealing closed vertical and horizontal joints of external walls, laying joints of rolled insulation materials

Purpose:

- installation of a new roof, repair of an old one (instead of a solid-bitumen coating or in combination with it);
- coating waterproofing of foundations, walls, for sealing closed vertical and horizontal joints of external walls, etc.;
- sealing of joints of rolled insulating materials;
- waterproofing of various surfaces (reinforced concrete, metal, wood, etc.);
- sealing of closed vertical and horizontal joints of external walls; 150
— гідроізоляція підлог (душові, ванні кімнати, санвузли).

Properties:
- is a thick mass, ready for use, which must be mixed if necessary;
- easily succumbs to the pressure of the tool used;
- has good adhesion to horizontal and vertical surfaces;
- forms a durable elastic coating;(//tractor-service.com)
- does not crack;
- work with mastic is allowed during rain, because mastic has the ability to displace water;
- has the property of flexibility at low temperatures;
— flow resistance and shrinkage at high temperatures.

Application:
The surface must be cleaned of weak damage, dirt and dust damage. Mastic is applied to a dry surface with a roller, brush, spatula, in a layer of at least 1 mm at an ambient temperature of at least 5 °C.
During roofing waterproofing works, the surface must be cleaned of weak, destroyed covering elements, dirt, dust, grease and other contamination. The mastic is applied to the surface with a brush, a spatula, a roller in a layer of at least 1 mm at a surface temperature not lower than 0 °C. The number of layers is at least two. Mastic consumption during application of one layer is not less than 1.3 kg/m2. The drying time of a layer 1 mm thick is 24 hours. Simultaneous application of several layers of mastic with the use of reinforcing material is allowed. At the same time, the drying time can increase to seven days.
To improve the operational properties of the coating, it is recommended to use roofing powder on the surface of the mastic layer.
Mastic is used as a ground layer during the installation of roofing material. Mastic is applied with a spatula or roller to a pre-cleaned surface in a layer 1 mm thick. Consumption of mastic is 1.3 kg/m2.
The drying time of the mastic layer is 24 hours. If the thickness of the layer increases, the drying time may increase. After the mastic layer has dried, a layer of roofing material is glued onto the surface using heating with a gas burner. Joints formed during the laying of roofing material are treated with mastic.
During anti-corrosion painting, mastic is applied to the prepared, cleaned surface using a roller or brush. The consumption of a single-layer coating is 0.2 kg/m2. A two-layer coating is recommended. If necessary, it is possible to dilute the mastic with a solvent (white - spirit,gasoline - solvent).
To increase the adhesion of the mastic and ease of work, in the cold season, it is recommended to pre-heat the mastic in a metalcontainer on a closed fire to 50 °C.

Storage: Keep away from fire and heating devices.

Packaging: Mastic is packaged in containers with a capacity of 5 kg, 10 kg, 20 kg, 45 kg.
