Through the resistance that our Floats are making during the grinding there will be a very good compaction. The floating produces a “rolling” of the sand and the small stones into the material. This “rolling” brings out of the material entrapped air and thus brings the effect of compressing the plaster. Plasterer Floats must have an abrasion, so that there is enough resistance during the floating. The special Foam allows a time-efficient working. In the process you need not to press the Float very intensive.
