Polymer modified, bitumen-rubber based, two-component waterproofing material.
It is a polymer-modified bitumen-rubber based, two-component, highly elastic
waterproofing material. It is used to protect structural elements below
ground level or at ground level, and those buried under soil, from the harmful effects
of water. It is only suitable for use on the positive side. It can
be applied to all mineral-based surfaces. It is resistant to seawater and underground
chemicals. It provides excellent adhesion to all mineral-based
surfaces. Once applied, it forms a continuous waterproofing layer. It is suitable for
use on horizontal and vertical structural elements that are constantly
underground and in continuous contact with water, protecting against humidity, leakage
water, and continuously pressurized water. After drying, it is
highly flexible and bridges shrinkage cracks. It can be easily applied with a brush or
trowel. It has high aging resistance under expected conditions,
and is resistant to water, various salt solutions, soil chemicals, and weak acids. It
can be safely used on surfaces in areas exposed to movement and
vibration. It contains no solvents and is environmentally friendly.

30 kg Plastic Bucket Set (Component A: 22 kg, Component B: 8 kg) Should be stored in a dry environment between +5°C and +35°C in its original packaging. Has a shelf life of at least twelve months when kept unopened in a dry, cool, and enclosed space.
During application and mixing, the material should be kept away from skin and eyes. In case of contact, wash thoroughly with water. If the material comes into contact with the eyes, rinse immediately with plenty of water and seek medical assistance. Protective gloves, clothing, mask, and goggles should be worn during use.
Ensure that the application surface is dry, solid, and clean. The surface to be applied should be free of residues such as dust, dirt, mold oil, or detergent that may prevent adhesion. The hardness, water absorption, and durability of the surface should be checked in advance. If there are any voids or moving parts on the surface, they should be fixed. Before the application, the surface should be checked, and if there are any areas that need repair, these should be first repaired with NANOREP FT 70/30 series repair mortars. After this process, the waterproofing application should be done after 7 days. The surface must have at least 25 N/mm² pressure resistance and at least 1.50 N/mm² pull-off strength. Before application, the surface should be primed with bituminous primer, depending on the roughness and absorbency of the surface. If necessary, a double priming process can be done. Moving parts should be fixed, and joints and seams should be sealed with expansion tapes. For freshly poured concrete, a curing period of 21 days must be observed. The application should be made when the moisture content drops below 10%. Before starting the application, BITUBOND 2C should be brought to standard room conditions (23±2°C) at least one day prior. Before and during the application of BITUBOND 2C, appropriate work clothing, goggles, and mask should be used according to health and safety regulations. The A component of BITUBOND 2C should be mixed with the B component, using a low-speed mechanical mixer, until a homogeneous mixture is achieved (mix at 500 rpm for 2-3 minutes). In cases where the entire product in the bucket will not be used, the mixing ratio of 22/8 should be followed. If applied, the primer should be left to dry before proceeding with the application. After a 1-2 minute rest, the homogeneous BITUBOND 2C mixture should be applied to the surface using a notched trowel, brush, or roller. At least two coats should be applied. Between coats, wait 1-2 hours depending on the ambient temperature. The second coat should be applied when the first coat has dried enough not to be damaged. The application thickness can be increased depending on the surface roughness and the water pressure the insulation layer will be exposed to (please refer to the consumption table). In areas exposed to temporary and permanent water pressure, an alkali-resistant glass fiber reinforcement mesh with a maximum weight of 110 g/m² should be placed over the entire surface after the first coat of BITUBOND 2C. The second coat should then be applied to completely cover the mesh and ensure a minimum application thickness of 4 mm.
