Interlux ACT Antifouling Bottom Paint Item # 870433
Description
ACT uses Ablative technology to provide excellent season-to-season protection. Ablative technology enables it to wear away with use and eliminates the build-up of old spent coatings and the heavy sanding needed to remove them. It provides excellent protection against all forms of marine fouling in waters with moderate to heavy fouling and can be used in fresh, salt and brackish waters.
Features:
- Ablative Technology provides excellent season to season antifouling protection for power and sailboats
- Ablative technology enables the paint to erode away with use which eliminates buildup and the need for heavy sanding
- Trusted and reliable antifouling paint used by boaters and boatyards for protection in salt, brackish and fresh water
- Overcoats existing antifouling paint
- Flexible application schedule
- Paint in the fall and launch in the spring

Not the Easiest to Apply
This is the first time I have used ACT; I chose it because it went over Micron CSC without sanding. I can’t speak to its effectiveness, but I do have two significant comments. First, it applies like driveway sealant so be careful selecting your equipment. I started using a foam roller but the paint was so tacky it fell apart quickly. I had more success with a regular roller with a 1/4” nap. Second, Interlux is using really thin metal cans, and both gallons arrived damaged (the outer packaging was intact.)
In general, the coverage was good and Defender’s price was excellent. If ACT holds up well in the Great Lakes I will continue to use it.

Nice paint for the money
This is the second year in a row we have chosen this paint. For the money it gives very good performance. It goes on thick as ablative should and dissipates at a ood rate

Easy to Apply
I had no difficulty applying this bottom paint and the results looked very good. Only time will tell if it performs well as a ablation surface.
