When spraying 1-part paints like TotalBoat Wet Edge, Interlux Toplac, Pettit EZ-Poxy, or Epifanes Monourethane paint, key factors include the type of spray application, nozzle size, pressure, thinning, and technique. These elements significantly impact the finish quality.

Initial reduction of these paints is crucial. Refer to the tech data sheet or label of each paint to determine the appropriate thinning solvent for spray applications. The percentage of thinner required can vary between 10%-40%, depending on the specific product and application conditions. Insufficient thinner may lead to improper atomization, while excessive thinner can cause sputtering and sagging during application. Personal judgment based on viscosity, flow, and environmental factors is essential. For warmer conditions, maximum thinning may be necessary. Examples of thinners include Totalboat Spray Thinner 101, Interlux 216, Pettit 121, xylene, and Epifanes Spray Thinner for 1-part paints.

These paints are suitable for application using airless, pressure pot, siphon, or conventional spray methods. While other methods may work, these are the recommended approaches. For airless spray, maintain a pressure of around 170 bar/2500 psi with a .33-.41 mm (11-16 thousandths) tip. In a pressure pot, use a pressure of 3.44-4.47 bar/50-65 psi (gun pressure) and 8-10 psi (pot pressure), with a tip size of .89-1.4 mm (35-50 thousandths). When utilizing a siphon cup, aim for a pressure of 3.44-4.47 bar/50-65 psi (gun pressure) and a tip size of 1.5-1.8 mm (60-70 thousandths).
