Screed ready for covering after three days

A beach snack bar in the Baltic seaside resort of Kühlungsborn needed a new screed floor with an area of 40 m2. In order to minimise any loss of earnings, the owner decided to get the job done quickly with Powerscreed RS Binder, an MC special. Powerscreed RS Binder sets very quickly, cures rapidly and deformation-free and therefore ensures both fast accessibility and early readiness for covering.
The quick-acting cement is mixed with 0/8 screed sand in a ratio of 1:5 to create a screed mortar compliant with EN 13813, ensuring that the w/c ratio does not exceed 0.45. For the Kühlungsborn job, 70 kg of Powerscreed RS Binder was used per batch to ensure readiness for covering after just three days.

And it worked: The screed was laid on Friday 5 April 2019 and was ready for tiling on the following Monday.

As quick-acting cements are generally more difficult to apply than normal cements, new MC-Easyscreed plasticiser was also added to the screed mix as a precaution. It reduces the screed's resistance to levelling and thus significantly improves its workability, as can be confirmed by delighted applicator Mike Köhnke of SoKo Fussboden GmbH.
