Abstract

An apparatus for mixing a catalyst with a resin and then spraying the mixture onto a surface. The catalyst is mixed with air before the catalyst/ air mixture is introduced to the resin in the mixing, tube. The sprayer is provided with a specially designed check valve to prevent resin and catalyst from back flowing into the air /catalyst supply line. The construction of the check valve prevents it from clogging or becoming stuck shut during operation.
