Begin mixing without all the liquid. Approximately 4-5 ounces should be held back from
a 50 pound bag of material.
Allow the material to false set after fully mixing. This may occur in as little as a
couple of minutes or as long as 20-30 minutes. The material will become significantly
stiffer when this has occurred.
Add the saved liquid and thoroughly mix. For some products the material manufacturer
will allow several ounces of additional water to be added in order to increase the
pumpability of the product.
Note: It is important to realize that with powdered materials, it is very necessary to
use the process described above in order to avoid the false setting of the material in the
hose or on the wall.
Finally, always pour the mixed material through the hopper screen. Never push clumps
through the screen and always discard clumps.
