Liquid Paint Directions:
On previously painted surfaces blistered and loose paint must be removed. Sandblasting is the optimum surface preparation. Clean painted and bare metal surfaces with POR-15 Cleaner Degreaser to ensure that the surface is clean, dry, and free from oil, grease, dirt, salts, and any other contaminants. Prime all bare areas with POR-15 High Temp Coating before a full coat is applied. Glossy surfaces should be roughened with 320 grit sand paper before recoating. Allow POR-15 High Temp Coating to cure for 24 hours on the surface before temperature is raised above 300°F for full cure.
Dry time: Cures to touch in 4 hours. Second coat can be applied in 24 hours, depending on ambient temperature and humidity. POR-15 High Temp reaches maximum hardness after heat exposure above 300°F (150°C) for 15 minutes and then allowed to cool down.
Clean up: Do not put left-over paint back into can. Clean all equipment immediately after use. At the same time, flush out all fluid lines and carefully clean pressure pots. Use clean POR-15 Solvent only. It is also good practice to periodically clean the spray tip or the fluid tip/air cap combination during the course of the working day or shift.
Aerosol Spray Directions:
Surface must be clean, dry an free of all oil and other contaminants before painting. Sandblasting is the optimum surface preparation. Protect surrounding areas from spray mist. Must be heat cured at a minimum temperature of 400°F (205°C) for two hours. More than one coat may be required for full hide.
Shake can at least one minute before and occasionally during use. Spray surface with steady, even strokes at a distance of 8 to 10 inches. Several light coats give a better finish than one heavy coat. For best results, recoat within 1 hour or after 24.
Cleanup: To prevent clogs in spray nozzle, hold can upside down and spray until clear gas appears. Completely empty cans may be recycled or disposed of with regular trash. Dispose of partially empty cans responsibly. DO NOT puncture, incinerate or compact.
