Abstract
A two part adhesive spray system is provided herein. This system provides numerous enhancements to the prior art including limiting overspray “fog,” saving on sprayed material because of a more efficient spray pattern, and providing a more efficient bond than that of the prior art. In particular, the present invention provides a spray pattern having both adhesive and activator. The activator is sprayed in a smaller spray area than the adhesive, which is sprayed on a larger area. As such, when sprayed on a substrate, the activator provides a rapid tack to hold a second adhered material to the substrate sufficient to hold it in place while the remainder of the adhesive dries and/or cures.
