Material base: Cements and polymer additive
- Solid surface, resulting in mechanical and chemical protection of walkable concrete surfaces (not suited for horizontal silo construction or similar structures)
- Quick and definite to set, resulting in fast progress of work
- No blistering on warm surfaces
- Excellent friction adhesion to mineral surfaces, high degree of functionality
Bitumen-free and polystyrene-free
- No bitumen seepage
- Good UV stability and is therefore ideally suited for sealing in visible areas (e.g. sockets being plastered)
- No layer thickness loss under pressure, high level of functional reliability
Elastic material behaviour
Remains permanently flexible and bridges cracks, thereby guaranteeing a high degree of functionality
Resistant to all standard chemically aggressive substances found in floors, as well as diluted acids and caustics that attack concrete
Solvent-free
The minimum application temperature is +5°C. It is essential that the effects of rain and frost and water stresses are prevented until both coats have completely dried. In the event of prolonged exposure to sunlight, discolouration cannot be ruled out and should therefore be avoided. Not for use in horizontal silos, biogas plants and similar systems. Not suitable for sealing against backwards flowing water and for sealing roofs. During application, it is recommended that you wear personal protective equipment (safety goggles, art. no. 0892 102 ff./gloves, art. no. 0899 435 ff.). The powder component contains cement; therefore avoid contact with skin.

"2C cement-based sealing" is used in the Würth building waterproofing system for the elastic and waterproof sealing of areas at risk of cracking, of terraces and balconies that are not positioned above living spaces, for protecting concrete surfaces designed for foot traffic, for sealing water tanks (not drinking water), swimming pools, wet and damp rooms and for cross-sectional sealing according to W4-E. Not suitable for water penetrating from behind or for sealing roofs.
For use in accordance with DIN 18533, Part 3, Table 1, lines 3 and 4, "crack-bridging mineral sealing compound (MDS)", for use on concrete substrates for water impact classes W1-E and W4-E.
The surface must be dry to slightly moist, and free from grease, oil, frost, tar and bitumen. Non-absorbent surfaces should be pre-wetted so that they are matt damp. However, puddle formation must be excluded. Absorbent surfaces must be primed with waterproofing system primer coat (art. no. 0893 212 100) to improve adhesion. Loose components and protruding mortar residues must be removed before commencing work. Sharp edges must be blunted and corner and transition areas must be rounded off by means of a chamfer with waterproof mortar (art. no. 0893 212 110). Recesses > Compensate 5 mm with waterproof mortar, art. no. 0893 212 110. Completely mix the liquid component (bag enclosed in pail) and mix into the powder component in portions using a slow agitator, art. no. 0702 836, or a mixing paddle, art. no. 0713 95 121. Carefully and thoroughly mix both materials until they form a pasty, clump-free homogeneous paste. A universal brush, art. no. 0693 009 5, or a smooth comb, art. no. 0695 943 ff., is used to apply "2-component cement-based sealing" in two layers; the first layer must be hardened before the second layer is applied. In areas at risk of cracking, reinforcement fabric (art. no. 08963 212 105) must be inserted into the layer of the first surface. On adjacent components (floor panels or similar structures), the seal must be applied to at least 15 cm of the front. A horizontal seal must be incorporated into the surface seal in all areas.
