The chemical compound behind the highly effective anti-slime additive Irgarol was unavailable for several years. Paint manufacturers substituted additional zinc in its absence to ensure similar antifouling performance. Bottom paints containing Irgarol are once again available, and are recommended for extra protection in medium to severe fouling conditions.
APPLICATION AND USE
PREVIOUSLY PAINTED SURFACES: With VC 17m Surface must be clean and dry prior to application of VC 17m. Sand areas that are loose or flaking with 320 grade (grit) paper. Clean with Special Thinner 216. with conventional antifouling paint Removal is best but if this is not possible, start sanding with 80 grade (grit) paper and progressively sand with finer grades until the final sanding with 320 grade (grit). Remove sanding residue.
BARE FIBERGLASS: Begin by scrubbing well using soap and water and a stiff brush. Rinse with fresh water. Wipe with Fiberglass Solvent Wash 202. Sand with 320 grade (grit) paper. Wipe clean.
BARE WOOD: Wipe clean. Sand surface, wipe clean.
STEEL/LEAD: (Keels & Hulls) Blast to near white metal surface (Sa 2.5).
Method Apply 2-3 coats on the area to be coated per season. Do not sand between coats of VC 17m.
Mixing Pour the powder (stored under the plastic hat) into the can. Stir or shake thoroughly.
Airless Spray Electric Airless Spray: Pressure: Full. Tip Size: 1.5-1.8 mm/60-70 thou. If spraying in hot, dry conditions or outside with wind, you can add VC 17m Thinner to VC 17m to slow down the dry time during application. Add up to 15% by volume. Spraying too far from the hull will cause dry spraying which will result in poor adhesion and negatively affect the antifouling performance of the product. Spraying of antifouling paints is prohibited in Canada.
Brush Do not brush apply.
Roller Use a short nap roller. Add V172 up to 15% should VC 17m be drying too quickly for application. Put just enough paint to fill the roller in the roller tray and put the lid back on the can.
Other Surfaces previously painted with VC 17m do not need to be sanded. Performance of the paint relies directly on the care taken in surface preparation, the application technique, and the number of coats applied. VC 17m is a copper color at application.
Some Important Points It takes several weeks of immersion to develop final color. It may not change color above the true waterline. Product temperature should be minimum 10 C/50 F and maximum 32 C/90 F. Ambient temperature should be minimum 7 C/45 F and maximum 35 C/95 F. Substrate temperature should be minimum 7 C/45 F and maximum 35 C/95 F.
Compatibility/Substrates Apply to clean, dry, properly prepared surfaces only. Bare surfaces must be sanded. Do not apply VC 17m over graphite antifoulings. Do not apply over soft antifouling paints. Do not apply VC 17m over aluminum.

TRANSPORTATION,STORAGE AND SAFETY INFORMATION
TRANSPORTATION: VC 17m should be kept in securely closed containers during transport and storage.
STORAGE: Exposure to air and extremes of temperature should be avoided. For the full shelf life of VC 17m to be realised ensure that between use the container is firmly closed and the temperature is between 5 C/40 F and 35 C/95 F. Keep out of direct sunlight.
DISPOSAL: Container Disposal: Triple Rinse (or equivalent). Then offer for recycling or reconditioning, or puncture and dispose of in a sanitary landfill or by other procedures approved by state or local authorities. Pesticide Disposal: Open dumping is prohibited. Pesticide, spray mixture or rinsate that cannot be used or chemically reprocessed should be disposed of according to procedures approved by Federal, state, or local disposal authorities.
