Product Description:

HI-TECH WP-NB 2K is a cementitious, two component crystallized waterproofing product. When applied on concrete surface on positive or negative sides the product provides waterproofing in depth by penetrating into concrete. The product provides high mechanical and chemical resistance on the applied surfaces. Chemical materials in its structure penetrate into concrete in depth by reacting with moisture and free lime present in the structure of concrete and form insoluble crystals inside capillary spaces and pores. It can be applied on new concrete surfaces. It decreases the duration of hydration and reduces shrinkage crack formation on applied surfaces. Protects concrete against corrosion and dilute chemicals. HITECH WP-AS700 fast setting mortar can be used in conjunction with the HITECH WP-NB 2K system to plug active water leaks in concrete and masonry.

Application Areas:

Internal and external waterproofing of horizontal and vertical surfaces
Water tanks, waste water and other reservoirs,
On concrete surfaces exposed to see water
Basement and foundation waterproofing
Internal and external insulation of enceinte walls. Canals, Tunnels, Bridge decks

Features:

-It has a wide usage area with its resistance to negative and positive water pressure.
- Resistant to chlorine and mild chemicals.
- Suitable for drinking water
- Safe use in buildings with fresh concrete
-Easy to apply with brush and trowel.
-Splinterproof
-Has high adhesion performance
-Prevents carbonation in concrete
- Non-corrosive to reinforcement or steel
-Due to its flexibility, it provides waterproofing without being affected by deformation in areas sensitive to vibration and slight building settlements.

Surface preparation:

Surface to be applied should be wetted before the application. Wetting of the surface should be performed at least two hours before starting to application and surface should be saturated with water. If surface is humid or wet this process is not necessary. Surface of application should be cleaned of materials such as dust, grease etc. Weak parts of concrete should be repaired with by Elastic Repairing Mortar. Dilatations should be filled with Elastic Filler. After surface preparation mixture should be prepared.

Preparation of the mixture & application:

Preparation of the mixture & application:
- Mix one drum (3 kg-B component) with 4.5-5.5 liters of clean water in a suitable container.
- Add the powder component(A component) under continuous stirring.
- Continue mixing for approximately 3 minutes. Mixing must be done with a low speed (400 rpm) mixer and a mixing tip. As a result of the mixing process, a homogeneous, lump-free and spreadable mortar is obtained.
When the mixing process is finished, the mortar has a homogeneous paint consistency that can be applied with a brush.
Note: if the consistency is thick, it should be thinned with water, if the application is in the form of plastering, the water ratio should be reduced.
Note: use a disintegrator type drill mixer bit as much as possible.

Application procedure:

The application is applied in three layers with the help of a brush, waiting 4 hours between the layers (but more than 24 hours)should not exceed.. The application should be applied in opposite directions on each floor. The surface should be completely covered when three layers are applied. The application should not be done in frost and extreme temperatures. It should be done in the evening or in the morning in cool places in summer. If frost occurs in cold regions, the floor or wall should be watered beforehand with hot water. If the applied surfaces will not be plastered from the back and will remain exposed, they should be moistened at 48 hour intervals. This process speeds up the curing process and provides more successful insulation.
NOTE: During and after the application surfaces should be protected from rain, water, mechanical loads and impacts for 24 hours.
