Yes you can. Here's the data from Interlux:


PREVIOUSLY PAINTED SURFACES:
with VC 17m and:
with VC 17m Extra with Biolux: Surface must be clean and dry prior to application of VC 17m Extra with Biolux. 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. Apply 3-4 coats of VC Tar2.
STEEL/LEAD: (Keels & Hulls) Blast to near white metal surface (Sa 2). Apply 3-4 coats of VC Tar2.


Method Apply 2-3 coats on the area to be coated per season. Do not sand between coats of VC 17m Extra with Biolux.


Hints Mixing Pour the powder (stored under the plastic hat) into the can. Stir or shake thoroughly.
Thinner V172
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 Extra with Biolux 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.
Brush Do not brush apply.
Roller Use a short nap roller. Add V172 up to 15% should VC 17m Extra with Biolux 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 Extra with Biolux 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 Extra with Biolux 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 10C/50F and maximum 32C/90F. Ambient temperature should be minimum 7C/45F and maximum 35C/95F. Substrate temperature should be minimum 7C/45F and maximum 35C/95F.


Compatibility/Substrates Apply to clean, dry, properly prepared surfaces only. Bare surfaces must be sanded. Do not apply VC 17m Extra with Biolux over graphite antifoulings. Do not apply over soft antifouling paints. Do not apply VC 17m Extra with Biolux over aluminum.


Number of Coats 2-3
