Abstract
A method of applying a two-part liquid composition to a workpiece is provided. In particular, a two-step method is provided wherein a first liquid composition is applied to the workpiece by roll coating, and a second liquid composition is applied by spraying the workpiece. Generally, the first liquid composition is a polyurethane adhesive and the second liquid composition is a polyurethane catalyst. By applying the reactive components of the polyurethane composition in two steps, the open time may be controlled.
