Stir contents well, then dispense a portion into a separate container and seal can at once, keeping lid and grooves clean to avoid permanently sealing can shut. Do not paint directly out of can. Like all POR-15 coatings, this should always be stirred, never shaken. Best Dispensing Method: Use coffee scoop or pouring spout. Do not put left-over paint back into can. Thin only with POR-15 Solvent , if necessary. Apply in thin, covering coats. SURFACE PREPARATION Surface to be coated should be dry and free of grease, oil, and other contaminants. Use POR15 Cleaner Degreaser (Marine Clean) , diluted 1 part Cleaner Degreaser to 8 parts water to remove light contamination. Then rinse with water and allow to dry. APPLYING OVER OTHER PRIMERS Repeat instructions above, then sand surface lightly with 240 grit sandpaper and wipe clean with dry tack cloth and paint. TO PAINT OVER A CURED POR-15 SURFACE Clean with Cleaner Degreaser as above, then sand with 300 grit sandpaper and apply one light to medium coat of POR-15 Self-Etching Primer . Allow to cure for 30 Minutes at 68ºF (20ºC), or longer in cooler temperatures. Apply POR15 Top Coat as final finish. Depending on temperatures and humidity recoat at 3-12 hour intervals. Spray or Brush Application: POR-15 Topcoat will need thinning using POR15 Solvent for all spray and brush applications between 10-20%. Use 25-35 lbs.(172-240Kpa) pressure for normal semi-gloss. Cleanup: Use POR-15 Solvent or lacquer thinner for cleanup, which must be done before the top coat dries; once dry it cannot be removed by solvent. POR15 Top Coat can take 3-4 days to reach maximum hardness or longer in temperatures below 55ºF 15ºC.
