Abstract: A method of making a setting type compound by injecting an activator compound into a plaster compound wherein the activator compound tube is coaxial and within the plaster compound tube, each at the same flowrate, the same pressure and the same viscosity. The cross sectional transverse areas of an annulus containing the plaster compound and the hole in the annulus containing the activator compound are the same.
