Preparation FACTORY PAINTED SURFACES: Sand with 80 grade (grit) paper. Wipe down with Brush-Ease 433 or Special Thinner 216 to remove sanding residue.
PREVIOUSLY PAINTED SURFACES: Sand with 80 grade (grit) paper. Wipe down with Brush-Ease 433 or Special Thinner 216 to remove sanding residue.
BARE METAL: Surface should be blasted to bright metal. For steel surfaces, grit blasting is preferred. For aluminum or other light alloys, sandblast if possible or grind with medium coarse grade (grit) emery cloth. Remove all blasting/grinding/sanding residues with a clean air line and sweep with a clean brush or broom. (Vacuum clean for best results.) Do not wipe with cloth rages after blasting or sanding as fibers may be pulled out and protrude through the primer coats.

Method Apply a minimum of 3 coats of Primocon. Primocon may be applied directly to blasted metals if applied within 1 hour after blasting. If sanded or if more than 1 hour has passed since blasting, prime bare metal with Viny-Lux Primewash 353/354.

Hints Airless Spray Pressure: 170-204 bar/2500-3000 psi. Tip Size: 0.53 mm/21 thou.
Conventional Spray Pressure Pot: Pressure: 3.44-4.47 bar/50-65 psi (gun pressure); 8-10 psi (pot pressure). Tip Size: 1.5-1.8 mm/60-70 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.8-2.2 mm/70-85 thou. When spraying with Siphon Cup equipment, reduce first with Special Thinner 216.
Other Apply extra coats of Primocon over riveted or welded areas. Do not sand between coats of Primocon or between last coat of primer and first coat of antifouling. There is no maximum overcoating time between coats of Primocon or between the last coat of primer and the first coat of antifouling paint. It is, however, suggested that after thirty days the surface is sanded and wiped clean before proceeding.

Some Important Points Product temperature should be minimum 10C/50F and maximum 29C/85F. Ambient temperature should be minimum 10C/50F and maximum 35C/95F. Substrate temperature should be minimum 10C/50F and maximum 29C/85F.

Compatibility/Substrates Primocon should be applied to freshly sandblasted metal, metal that has been etched with Viny-Lux Primewash 353/354 or to previously painted surfaces. Do not use under vinyl based antifouling paints such as VC Offshore or Baltoplate.
