Interlux ACT Ablative Antifouling Bottom Paint

Interlux ACT bottom paint provides premium seasonal antifouling protection in moderate to heavy fouling areas from algae, slime, barnacles, and zebra mussels. It is compatible with (and can be applied over) other antifouling paint as long as that coating is in acceptable condition. 'ACT' stands for Interlux's Ablative Copolymer Technology, which constantly exposes fresh biocide for anti-fouling protection throughout the season. ACT eliminates the problem of old coating buildup and associated need for heavy sanding to remove. ACT is very effective at controlling shell fouling such as barnacles and zebra mussels and contains a Slime Fighter to control weed, slime and algae growth, keeping the bottom cleaner longer.

APPLICATION AND USE

Apply Fiberglass Surface Prep YMA601 with a maroon, 3M Scotch-BriteTM pad and scrub well. Flush with fresh water or wipe off with a clean, wet cloth ensuring that no traces of Fiberglass Surface Prep remain. An alternative method would be to dampen a cheesecloth with Interlux Fiberglass Solvent Wash 202. Wipe thoroughly to remove all surface contamination and cleaners. Wipe off with a clean, dry rag before liquid dries. To be certain the contamination has been removed, run water over the surface. If the water beads up or separates, repeat one of the above methods. When the water sheets off, all contamination has be removed. Sanding does not remove contamination. After the surface has been properly prepared follow the application system below.

Bare Fiberglass - No Sanding System: Clean surface as above. Apply one thin, continuous coat of Interlux Fiberglass No-Sand Primer with brush or roller (do not spray; do not sand). Follow application guidelines for the primer and apply Fiberglass Bottomkote ACT with Irgarol.

BARE WOOD: Sand with 80 grade (grit) sandpaper and remove sanding residue with Special Thinner 216. Repair defects with Watertite, then sand and wipe clean. Apply first coat reduced 10% with Special Thinner 216 or Brush-Ease 433. Fill seams, if necessary, with Seam Compound Brown 30. Apply 2 further coats of Fiberglass Bottomkote ACT with Irgarol.

PREVIOUSLY PAINTED SURFACES: In Good Condition: Wet sand surface with 80 grade (grit) paper to a clean firmly attached surface. Clean with Special Thinner 216. In Poor Condition: Use Interstrip to remove all traces of antifouling. Sand and wipe clean with Fibreglass Solvent Wash 202 for fiberglass and wood substrates. For steel, sandblast or grind to bright metal finish.

I used ACT on a 22' boat and got 4 years of life with 3 coats. Antifouling properties are good, had minimal cleaning at the end of the season. Just purchased more and I hope it does as well as the previous paint job. Jamestown had the best price and super fast delivery!

This is the product they advertise - but what you get is the new interlux product that is replacing Fiberglass Bottomkote ACT which is what I ordered. The 'new' product has about 1/2 of the copper as the old and 30% more 'inert' ingredients. I have yet to apply it to my Newport 30 but will write a review when I use it.

This bottom paint was easy to roll on my sailboat bottom and also easy to brush in between my rudder and the hull. The color looks great and there are no overlaps. A great replacement for Bottomkote Classic.

Drys very fast in warm weather so work fast or recruit some help. 3/8" nap roller worked for me and cleans up with mineral spirits.
