APPLICATION AND USE

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, wipe surface clean with 202 Solvent Wash, then sand to a bright finish with 36 grit abrasive. Follow up with 2316 thinner immediately after sanding, and apply Primocon as per instructions.

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 10 C/50 F and maximum 29 C/85 F. Ambient temperature should be minimum 10 C/50 F and maximum 35 C/95 F. Substrate temperature should be minimum 10 C/50 F and maximum 29 C/85 F. Primocon prevents leaching of TBT from an underlying antifouling coating provided it is applied at a minimumdry film thickness of 3.5 mils (minimum of 2 coats by roller) & that the film remains intact. We have studied the leaching rate of TBT from a TBT SPC antifouling (such as Micron 44) overcoated with Primocon (applied as specified) & seen that TBT leaching is prevented. The leaching rate determination method used was ASTM D5108-90 (2002) Standard Test Method for Organotin Release Rates of Antifouling Coating Systems in Sea Water.

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.

Good product, use it for more than just boats.
By Obsession 1987&2000 from Long Island, NY

May need to add Brush Ease 433 as you are painting, product dries very fast and thickens as you use. Works great on any kind of metal as a primer or alone. I use it on more than just boats. I was very happy with results. Used it as a tie coat on unknown previously painted boat bottom , one coat, than 2 coats Iterlux Bottomkote NT finish. Came out great!

Bottom Line Yes, I would recommend to a friend
