Notteproof PB2K

Description

NOTTEPROOF PB2K is a two-component, bitumen polyurethane-based, plant root-resistant, liquid waterproofing material. It adheres strongly to the applied surface and forms an elastic film. It is suitable for vertical and horizontal application.

Usage Areas

Floors
Under-coating areas
Foundations and curtains
Gypsum and cement panels
Under cladding on terraces, roofs, and balconies

Characteristics

The product can be applied using a brush, roller, or suitable spraying machines.
It has plant root strength and can be used in green roof applications.
When applied, it forms a seamless and leak-proof insulation layer.
It has an elastomeric, hydrophobic structure.
It effectively allows water vapor to pass through, preventing moisture accumulation.
Damaged parts can be easily repaired in a short time.
It provides effective resistance to chemicals.
It is ideal for vertical applications and does not leak or sag.

Application Method

Before application, surfaces should be free from substances that may weaken adherence, such as wetness, grease, paraffin wastes, cement syrup, loose particles, mold release agents, and cured old membranes.
If possible, surfaces should be washed with high-pressure water, cleaned, and dried.
Surface defects should be repaired with appropriate products.
For absorbent surfaces like concrete, cement, and screed, NOTTEPROOF P140 should be used, ensuring a maximum humidity of 4%.
For damp or non-absorbent surfaces, NOTTEPOX P355 should be used.

Each product should be opened individually and mixed with a low-speed mixer for 2–3 minutes.
The A and B components are then combined and mixed with a low-speed mixer for a minimum of 3–4 minutes.
The product should be poured onto the primed surface and applied in a minimum of two coats using a roller, brush, or trowel until the entire surface is covered.
After the first coat is applied, the second coat should be applied within a minimum of 6 and a maximum of 24 hours.

Packages should be used entirely upon opening and within the specified periods.
After application, the surface should be protected from water, rain, dew, frost, and snow until it is completely dry.
Once the product is fully dried, it should be covered.

Consumption

1.50 – 2.00 kg/m² (for 2 layers of application)

Packaging and Storage

30 kg Tins (set):
- Component A: 15 kg

Shelf life when stored in its original packaging at +10°C / +30°C in dry, protected, and ventilated environments, protected from sun, rain, and frost, is 12 months from the date of manufacture.

Safety Precautions

During application and mixing, contact of the material with the skin and eyes should be prevented, and in case of contact, it should be washed with plenty of water.
In case of contact with eyes, they should be washed immediately with plenty of water, and medical assistance should be obtained.
Gloves, protective clothing, mask, or goggles should be used during use.
