ABSTRACT:
Plastic foam is expelled from a slit-shaped nozzle under high enough pressure to break up the plastic foam into generally discrete particles which are propelled toward a surface to be coated with foam at a relatively high velocity. Upon striking the surface, the particles exhibit good adhesion and mechanically key into the substrate upon which they impact. The invention is particularly useful for coating the surface of a landfill for daily sealing of the upper surface thereof.
