A:  Hi Dik629, here are the suggested directions AIR PUMP METHOD :The recommended equipment is an airless pump with pressure of 1,500 to 2,000 psi. A fluid delivery of 1 to 2 gallons per minute with a spray tip of 0.026 to 0.035 will be adequate. Wait 24 hours between coats. The hoses should be at least 3/8" inside diameter and of the high-pressure rate type. If the hose length is more than fifty feet, a larger inside diameter will be required. Only use a gas powered sprayer. The electric sprayer can burn down. We recommend GRACO and I see that you have one.
