ABSTRACT:
An apparatus for mixing and spraying a catalyst with a resin onto a surface. The resin and catalyst are internally mixed in confluence with pressurized air. The sprayer is provided with a specially designed check valve to prevent resin and catalyst from entering the pressurized supply line. The construction of the check valve prevents it from clogging or becoming stuck shut during operation.
