The mixed product is to be poured on a dry surface in the shattering with a thickness of 10 - 50 mm, on top of webertec 311 MC / webertec 313 EHS. The flowability characteristic of the product will allow a self-leveling action and the help with steel trowel is always recommended. The finished product will be set within 2 – 5 hours.
