The plaster is taken out of the bucket and spread on Styrofoam. Then it is equalized (structured) to form a homogeneous surface. On larger buildings, workers start applying the plaster on the highest level and work from (e.g.) left to right and top to bottom. There is always freshly applied plaster overlapping plaster that has been applied 30 min to 1 hour before. The overlapping zones do not look homogeneous if the plaster does not contain an open time prolonger.
