ABSTRACT:
A pulverulent fiber-reinforced spray mix is disclosed in which about 0.02 to 0.3 wt. % of flexible, thermoset polymer fibers resistant to decomposition at a temperature up to about 400.degree. F. are added for each 100 wt. % of other solids in the mix to form a mix which both avoids formation of mat-like structures in the dry hopper of refractory spray apparatus and provides a sprayed lining that is resistant to cracking and peeling during dry-out and preheat. The invention also comprises sprayable compositions formed by admixing water with the mix.
