Hempel Silic One Bottom Paint

My bottom paint is Hempel Silic One ablative paint. Data sheet says that it is silicone-based and that it may be over-painted with other brands of antifouling. I don't know what silicone-based means. I am concerned that I may have problems switching to one of the Micron paints. Does anyone have experience with over-painting this paint with a different antifouling?

The manufacturer of your new paint will usually tell you whether it's compatible over your older paint. I would pick a new paint and email the manufacturer to see if it's compatible over your old.

I switched from an ablative to a hard paint and ended up sanding the old off. It was worth the cost (peace of mind) which was about the same as my new paint.

I'm tired of fast moves, I've got a slow groove, on my mind.....
