Micron CSC bottom paint

[fordo]

Last winter I had the bottom stripped of 30 years worth of flaking hard bottom paint. I coated it with Interprotect 2000e barrier coat and put on three coats of Micron CSC (1 green, then 2 Black). The paint adhered well and worked really well but I'm down to the green at the bow, the leading edge of the keel and the trailing edge of the rudder. My question is, can I repaint with the CSC this fall, while the weather remains warm, or should I wait for the Spring? Should I paint the worn parts this fall and put a new, full coat on in the Spring? Will it hurt its effectiveness if I paint now?

The instructions on the can say that boats can be hauled & relaunched with no reduction in effectiveness. This would indicate that you can paint anytime it's convenient. The paint works by "washing off". It obviously won't wash off while the boat is hauled. Watch overnight temperatures if you paint in the fall.

And it is a good idea to put extra coats on the high wear spots when you paint.

Contact Interlux. MAny of their paints are required to be launched within 30 days of application. I seem to ecall that Micron is among them ...

I always paint in the spring, just before launch. I can attest to the "multi-season" protection of CSC Micron; I got three full years of protection out of the last coat of CSC. Just touch ups on the leading edge of the rudder and at the bow every year, but the rest of the bottom was fine.

I use the more or less the same Micron Extra and wonder how long did you two coats last as my paint shows very little wear after one season ?

Kind of cold right now as they want it above 50 DEG for 24 hours

Micron CSC is the only bottom paint I ever used and it would last 3 years before needing sanded and replaced. I hauled my boat yearly in the fall and would put a coat on the leading edge before launch in the spring. Even with winter storage in the hard (approx. 4 months) I had minimal growth over the season in the lower Chesapeake where the water temp gets above 80.

Paint it when it is convenient and as others mentioned put an extra coat or two on all the leading edges and waterline.

I checked with Interlux and was told that as long as I am painting over the same paint that no sanding is needed; just a clean surface and a solvent wipe will prepare the paint to adhere properly and, since it is a multi season paint I can paint whenever the weather permits; I don't have to launch within any time frame.
