Hard aggregate dry-shake method is an alternative acc. to DIN 18560-3 and -4 to achieve a surface modification of a concrete floor. This surface modification serves to increase the wear resistance and the surface hardness, however, cannot be compared with a hard aggregate layer acc. to DIN 18560-7.

KORODUR dry-shake products are based on hard aggregates acc. to DIN 1100.

The dry-shake is carried out dry on the fresh screed or concrete surface – manually, with sprinkling cart or spreader.

KORODUR hard aggregate layers are

Processing :

NEODUR HE 2 is processed in dryshake method for the production of industrial screeds with integrated wearing topping. Precondition for a correct processing of NEODUR HE 2 is the correct initial consistency of the previously installed concrete/screed. (Attention: not for airentrained concrete!). The installed concrete/screed must have set so far that the surface is just walkable. As soon as this point of time is given, the concrete/screed is trowelled by means of disk float in order to concentrate cement paste on the surface to serve as bond aid. Apply NEODUR HE 2 uniformly in dry condition. Immediately after moisture penetration, work in the applied NEODUR material by using disk float. A further analogous application can be carried out as long as the NEODUR dry mortar still moistens. Afterwards timely smoothing of the surface by using wing float.


After final processing of top layer curing must be done according to DIN 1045 standard. to avoid rapidly lost of wayer content of concrete and NEODUR, top surface must be covered by polyethylene sheet, KOROTEX or KOROSEAL material.

After curing expansion joints must be apply on surface and final surface will be cut by a mechanical cutter machine. Dimension og cutting could be varried from 1.5*1.5 to 3*3 meter. Joint must be filled by proper material.
