How can screed rapidly ready for covering be installed?

With UZIN SC 980.

Screeds have a drying time of at least 28 days. Especially when using CEM II cements and calcium sulphate screeds, the drying time may last much longer in the context of high thicknesses and increasingly complex flooring construction.


The solution for shortening the drying times and thus making rapid progress at the construction site comes with the low-shrinkage rapid cement UZIN SC 980. It consists of a hydraulically setting special binding agent, ensuring rapid and practically shrinkage and tension-free setting. Regard of the floor covering, the surfaces are ready for covering less already after 24 hours* without the risk of rewetting. Thanks to its reduced shrinkage, screed areas up to 200 m2 2 are possible with UZIN SC 980 without joints.

 

* At 20 °C and 65 % relative humidity.
