Abstract
The invention is a system of spraying coating on the surface of a substrate with a convergent spray gun that utilized separate pump and flow metering systems. Each part of a two part resin is pumped and metered separately. The third part which is a foaming agent and surfactant is also pumped and metered separately in a mix chamber. All three materials are mixed in the mix chamber and then atomized and combined with dry filler in the convergent zone of the spray gun. The quantity of the filler and the three part foaming resins are proportioned in order to maintain a predetermined ratio.
