- Is tested according to DIN19573 XWW4 -B2 and exceeds the requirements by far
- Is perfectly suited for wastewater structures with very heavy BSK (biogenic sulphuric acid corrosion) contamination
- Can be applied by hand coating, wet spraying and the centrifugal process (KS-ASS)
- Can withstand water after 4 hours (at 20°)
Further properties
The special WW mortar ERGELIT-KS2 bL is the versatile corrosion protection mortar for the particularly aggressive environment of BSK in wastewater structures. It is ideal for use as a joint mortar and coating mortar - whether you need to close joints or coat surfaces, ERGELIT-KS2 bL offers you the solution.
ERGELIT-KS2 bL has been tempered with organic and inorganic additives to offer you a product of the highest quality. With its special properties, ERGELIT-KS2 bL is a high-quality, cementitious one-component corrosion protection mortar. Here are some of the outstanding features that make ERGELIT-KS2 bL stand out:
Versatile application options: Whether by hand coating, wet spraying or using the centrifugal process (KS-ASS) - ERGELIT-KS2 bL can be used in a variety of application methods. You have the flexibility to choose the right method for your project and still achieve the same high quality and protective effect.
Tested quality: ERGELIT-KS2 bL has been tested in accordance with DIN19573 XWW4-B2. This stringent test confirms the outstanding quality and performance of the product.
This WW mortar is therefore ideal for wastewater structures with severe BSK corrosion (biogenic sulphuric acid corrosion). Thanks to its special properties, ERGELIT-KS2 bL offers reliable and long-lasting corrosion protection that meets the high requirements of this aggressive environment.
Fast water resistance: Time is crucial, and with ERGELIT-KS2 bL you save valuable time. ERGELIT-KS2 bL is water loadable after just 4 hours, even at a temperature of 20°C. This fast curing time allows you to speed up the construction process and complete projects more efficiently.
