For fresh water AF 33 with some Bioboost to guard against slime would be sufficient. See our Ablative Bottom Paints/ Bioboost.
Usually if the existing bottom paint is in good condition you can just scuff with 80/100 grit, rinse, dry and apply as most bottom paints are compatible. If the current paint is flaking off or really think and you’re removing a large portion or it’s going to the fiberglass you should prime with something like Barrier Coat Primer.
Just pulled my boat ( USY 18-freshwater) & pressure washed it . I had some Interlux ACT bottom paint left over from last year ,and I wanted to use it before it solidified in the can. The paint was powdery and rubbed off on my hands .To avoid painting over loose paint ( I've done enough houses to know). I thought that a wipe with DENATURED ALCOHOL would do the trick, and the local boat repair guys thought so, too.( well. it seemed like a good idea at the time). Naturally, the alc acted as a solvent and all the bottom paint below the waterline came off ( Suprisingly, paint above the waterline was solid). So I scraped it, feathered the edges and put on the paint. Now, I see that
Interlux recommend 60 day max to put the boat back in. I don't want to put her back in in Feb, so I was thinking that applying another coat before launching in the spring might be best. What do you think???
So for future reference what would have been the RIGHT thing to do?
Thanks for your help
