Bottrop, 17 June 2015. Even where a screed layer has been properly installed, cracks can appear at the surface that may even run through the entire cross section. Left unrepaired, they can develop into more serious forms of damage. MC-Bauchemie offers an impressive range of product systems that enable cracks in screed to be permanently and rigidly sealed. Now, with its new two-component reaction resin MC-Estrifan RIS-SL, the company has developed a product that is easy to use and will reliably, quickly and efficiently repair cracks and seal joints. Application could not be easier: The base and hardener are first mixed in a bottle and then simply poured into the gap.
