Maxi BP 2000

Bitumen-polyurethane based, dual component, fast curing, super elastic waterproofing material. A polyurethane-based, two-component, fast-curing, elastic, cold-applied, elastic liquid membrane enriched with bitumen for waterproofing and protection. Adheres strongly to almost any type of surface, creating a highly elastic film. It is used as an insulation material against moisture, unpressurized and pressurized water in the waterproofing of the foundations, curtain walls, terrace roofs, balconies, parking lots, bridge tops and similar areas of all buildings. It is also used in wet volume insulations. Thanks to its excellent consistency, it is easily applied even on complex details and creates a seamless waterproofing layer. It is highly resistant to water ponding and freezing. It blocks water vapor. It has crack bridging properties. Even if the membrane is damaged in any way, the damaged part can be detected and easily repaired in a short time.

General Characteristics
It can be used on all mineral-based surfaces, offering high adhesion. It has 2000% elasticity and is resistant to salt solutions and weak acids. It is durable against freeze-thaw cycles. It forms a seamless, continuous insulation layer. It can be easily applied with a brush, trowel, or spraying machine.

Packaging & Storage

Component A: 20 kg Metal Can. Component B: 20 kg Metal Can A+B Set: 40 kg. It should be stored in its original packaging in a dry environment between +5°C and +35°C. In unopened packaging, it has a shelf life of at least twelve months when stored in a dry, cool, and closed area.

Safety Recommendations

During application and mixing, contact of the material with skin and eyes should be avoided. In case of contact, wash with plenty of water. If the material comes into contact with the eyes, rinse immediately with plenty of water and seek medical help. During use, gloves, protective clothing, mask, and goggles should be worn.

Application Method

Before application, the surface should be inspected, and if there are areas that need repair, they should be repaired using NANOREP FT-70/30 series repair mortars. After this process, water insulation application should be carried out after 7 days. The surface should have a minimum compressive strength of 25 N/mm² and a minimum pull-off strength of 1.50 N/mm². Before application, the surface should be primed with NANOPUR-NANOPOX series primers, depending on the roughness and absorbency of the surface. If necessary, a two-coat priming process can be applied. Under all conditions, the moisture content of the surface to be applied should be below 4-6%. The primer consumption varies depending on the quality and absorbency of the concrete. Make sure the primer is fully cured and hardened. Water insulation can be applied after at least 4 hours and at most 48 hours. Fresh concrete surfaces should not be applied to. All drains, channels, and filters should be sealed using sealing tapes. The surface to be insulated should be dry. Before starting the application (at least one day before), MAXI BP 2000 should be brought to standard room conditions (23±20°C). Appropriate work clothes, goggles, and masks should be worn in compliance with occupational health and safety rules before and during the application of MAXI BP 2000. MAXI BP 2000 is supplied in ready-to-use sets according to the mixing ratio. Before mixing, ensure the material temperatures are between +15 - +25°C. Component B should be mixed for 4-5 minutes using a mechanical mixer at 300 - 400 RPM, without introducing air, until a homogeneous mixture is obtained. Then, all of Component B should be poured into Component A, ensuring that no material remains in Component B. After mixing A and B components for at least 4-5 minutes until homogeneous, it should be used. The prepared mixture should be applied to the surface using a stiff-bristled brush or spray machines. After the material completes its reaction, the second coat should be applied in a vertical direction to the first coat. The waiting time between coats is at least 12 hours. After the first coat is applied, check by pressing your finger on the surface. When no impression is left, proceed to the next coat. Fine cracks, joints, corners, and edges should be supported with geotextile fabric after the first coat application. In terrace roof and similar applications, geotextile fabric should be applied to the entire surface after the first coat application. After completing the coating, the coating should not be exposed to direct water contact and the air temperature should not fall below +8°C within 36-48 hours.
