Bitümento BT2K 600
ADVANTAGES
- High elasticity and capability of bridging cracks.
- Not affected by microorganisms and aggressive underground waters.
- Forms a flexible, covering and continuous asphalt layer on horizontal and vertical surfaces, dry and slightly moist surfaces.
- No damage to environment as it is water based. Easy to use indoors.
- No swelling and flaking by time due to very good adherence.
PLACES OF USE
- As water and moisture tight material in underground applications such as foundation, base wall and basement,
- Protection and isolation of structures and structural elements which are exposed to seepage water and continuous or temporary water pressure,
- As water proofing material in dry or slightly moist details such as , kitchen, bathroom, etc.,
- Insulation of mineral surfaces such as concrete, stone, brick, briquette, plaster, grout, etc.,
- Repair of old isolations such as bituminous membrane, asphalt, etc.,
- Fastening of heat insulation boards,
- Isolation application with resistance to higher pressure water, together with isolation net, isolation fabric, etc.

SURFACE PREPARATION
The substrate should be free of dust, dirt, rust and oil, and loose parts scraped. The steel and wooden dowels should be removed from the surface. Wide cracks and gaps should be filled with Elastopast or Elastomast. The corners and edges should be rounded by at least 4 cm in diameter. Bitümento BT2K 600 should be applied on dry concrete.
APPLICATION
Application temperature: +5 oC / +35 oC
Application surface temperature: +5 oC / +30 oC
Working Time: 1-2 hours
Drying time *: min. 48 hours
Mixing ratio (by weight):
liquid component : 3
powder component : 1
Mixing:
Mixing ratio : 3 parts by weight liquid component
1 parts by weight powder component
The powder component should be added in the liquid component slowly, and mixed in a mixer with 400-600 rpm for 3-5 minutes until a homogeneous mixture without lumps is obtained. The mixed material should be consumed up within 1-2 hours.
Priming:
Apply ready-mixed Bitumento BT2K 600 , diluted with 1:5 with water, or the bitumen emulsion BTR200, diluted 1:2 with water or liquid component of BT2K 600 diluted 1:10 with water, to the substrate. The material should be applied on the surfaces by means of a brush without allowing accumulation of material. The primer should be allowed for drying, and then the main application should be done.
Application of Coating:
After the primer dried, it is applied in a thickness of 2-5 mm by means of brush, trowel or appropriate spray equipment.
It may be applied in higher quantities depending on the absorption, porosity of the surface and the water pressure to which the waterproof layer will be exposed.
In case of double-layer application, the first layer should be allowed for curing and then the second layer should be applied. It is recommended to use with 50-100 gr/m² fiberglass or net to improve mechanical properties in large areas and horizontal ? vertical joints and to bridge the cracks. The mixture prepared should be consumed up within 1-2 hours depending on the weather temperature.
The application tools should be cleaned with water immediately after application. The tools which have not been cleaned timely, may be cleaned with thinner later.
Considerations:
- It should not be applied at temperatures below +5°C or in cases where the temperature is expected to drop below +5°C within 24 hours following application.
- The mixture should be prepared only with the liquid and powder components of the product. No foreign substance should be added.
- It should not be applied on wet and frozen surfaces. The application should not be made on surfaces at temperatures below +5°C?den or above +30°C.
- The application should be protected against dew, frost, etc. until it fully dries.
- The coating should be applied on those surfaces of the structure and structural elements which are in contact with water.
- In foundation isolation applications, the waterproofing layer should be protected against mechanical damage by heat insulation boards, drain sheets or bricks before filling.
- The soil filling should be applied at least 3 days after waterproof application.
CONSUMPTION
- Insulation against moisture:
min. 3.3 kg/m2 for a thickness of 3 mm - Against non-pressure water:
min. 4.4 kg/m2 for a thickness of 4 mm - Against pressurized water:
min. 6.6 kg/m2 for a thickness of 6 mm - min. 2 kg/m2 for fastening Heat Insulation Board
As primer;
use of liquid component by adding 1:10 water
0.20 - 0.25 kg/m2
use of mixture by adding 1:5 water 0.5 - 0.8 kg/m2
NOTE: The consumption quantities may vary depending on the application details and surface smoothness, absorption.
PACKAGING
