İnoflexibit 2K - Two Component Bitumen Based Waterproofing Coating
2k Inoflexibit
İnoflexibit© 2K is a two component, fibre reinforced, solvent free bitumen based brush applied coating developed to provide waterproofing on building surfaces in contact with soil. The liquid component consists of a polymer modified bitumen emulsion and the powder component of a cement based binder. When the two components are mixed, the powder component binds the water within the emulsion and the mixture begins to harden chemically. For this reason the coating cures not only by evaporating its water but by reacting within itself. Its thixotropic consistency prevents it from running on vertical surfaces, while the fibre reinforcement supports the crack bridging behaviour of the cured film.
İnoflexibit 2K Functions
İnoflexibit© 2K works to prevent water from reaching the concrete on building surfaces that remain below ground. Because it is applied by brush, trowel or spray, it forms a seamless and continuous layer regardless of the geometry of the surface. Since the cured film remains bonded to the surface, water finds no path between the coating and the concrete. Its fibre reinforced flexible structure accommodates movements that develop in the concrete over time.
Seamless Coating
In sheet or roll based waterproofing systems, the overlaps are where water passage is most likely to occur. Because İnoflexibit© 2K is applied as a liquid coating, it forms a seamless layer across the entire surface. The same continuity is maintained at details such as corners, returns and pipe penetrations.
Crack Bridging
Concrete develops fine cracks over time through drying shrinkage and the effect of loading. The fibre reinforced flexible structure of the cured coating covers these cracks without interruption and prevents water from travelling through them. The coating accommodates the movement of the crack through its own elongation capacity.
Adhesion on Vertical Surfaces
Thanks to its thixotropic consistency, the product remains at the applied thickness on vertical surfaces and does not run down. This behaviour allows sufficient thickness to be achieved in a single coat on retaining walls. The cement based powder component supports adhesion to the surface after curing.
The Powder Component Binding the Emulsion Water
Single component bitumen emulsions cure solely by evaporating their water. Film thickness therefore depends on weather conditions, water becomes trapped within a thickly applied layer and drying slows down. İnoflexibit© 2K removes this constraint. Because the cement based powder component entering the mixture binds the water within the emulsion chemically, the layer hardens not only at the surface but throughout its mass. As a result a thicker layer can be achieved in a single pass and curing becomes less dependent on the drying rate of the environment. The counterpart of the same mechanism is this: since the reaction begins the moment of mixing, the prepared material must be used within its pot life, and because cement hydration slows at low temperatures, application is not carried out below +5 °C.

Frequently Asked Questions
1. What Is İnoflexibit 2K?
İnoflexibit© 2K is a two component, fibre reinforced, solvent free bitumen based brush applied coating developed to provide waterproofing on building surfaces in contact with soil. The liquid component consists of a polymer modified bitumen emulsion and the powder component of a cement based binder.
2. What Does the Two Component Structure Provide?
Single component bitumen emulsions cure solely by evaporating their water, which means a thickly applied layer dries slowly. In İnoflexibit© 2K the cement based powder component binds the water within the emulsion chemically, so the layer hardens throughout its mass as well. As a result a thicker layer can be achieved in a single pass and curing becomes less dependent on the drying rate of the environment.
3. Which Surfaces Is It Applied To?
It is applied to mineral based surfaces such as exposed concrete, cement based render and screed. A damp surface does not prevent application, but the product must not be applied over a frozen layer.
4. Why Does Application Temperature Matter?
Application should not be carried out when the air and surface temperature is below +5 °C. Because the curing reaction of the powder component slows at low temperatures, the coating cannot develop its expected strength. High air temperature has the opposite effect, shortening the pot life of the mixture and increasing its fluidity.
5. How Long Can the Mixture Be Used After Preparation?
Since the curing reaction begins the moment the two components are mixed, the prepared material must be used within its pot life. For this reason the mixture should be prepared only in the quantity that can be applied. Pot life varies with ambient temperature and shortens in hot weather.
6. How Is İnoflexibit 2K Packaged?
The emulsion component is supplied in 22 kg plastic buckets and the powder component in 8 kg bags. One set is supplied as a total of 30 kg.
