Micron CSC is an great multi-season ablative bottom paint with a copper-copolymer formula that provides controlled release of antifouling biocides at the paint surface.
The longevity of the coating depends on the amount of paint applied. CSC retains its effectiveness even when the boat is removed from the water for extended periods (winter storage, for example). To reactivate come springtime, use a stiff brush or powerwash lightly. Suitable for sailboats and power boats.
Available in Black, Blue, Green, Red, and Shark White colors in Quart and Gallon sizes. Dark Blue is available in Gallon size only.

I have a 43' fin keel sailboat with Micron 66 bottom-coat. This year, we will be in the Great Lakes and rivers to Mobile Bay; i.e., in fresh water all season. The Micron 66 is in pretty good shape, but needs a bit of touch up in a few places. Interlux recommends not using Micron 66 in fresh-water. Can I apply Micron CSC (on top of the Micron 66) at the water line and high-wear and touch-up areas to get me through the season in fresh-water? What surface prep is necessary prior to application of CSC on top of 66?
Unfortunately if you are going to put anything other than Micron 66 on top you will need to Remove the Micron 66 first.

Hi, What is the difference between the CSC I have used for years and CSC HC ?I have a 20ft bowrider that is in brackish water ftom May to the end of September, then wintered on a trailer and relaunched.I have been getting two seasons with the CSCThanksMike G
CSC HS dries to bright colors. This new coating provides excellent antifouling longevity against all types of algae, weeds, barnacles, and other shell fouling. Micron CSC HS is intended for use below the waterline in fresh, salt or brackish water on fiberglass, wood and properly primed metal boat hulls and parts.In addition, this technology allows the boat to be hauled and relaunched the following season without repainting.The HS is a brighter color formula.

I have a 17 foot boat I use in salt water it had bottom pain and it is completely worn off and in some cases it pealed I am down to bare fiberglass that was originally sanded what prosecutors should I proseed with ?
The best would be to soda blast and start over. You need to barrier coat the bare parts with 2000e interlux then give it a full coat of the csc.
Last time I used CSC was years (1992 ? ) when I went from freshwater to saltwater. At that time I sanded down to gelcoat. should have gone to fiberglass??.applied 6coats 2000/2001 then 1st coat of CSC was RED Next 4 coats..maybe a little too much? Was BLACK. CRUISED on my boat untill 2004 put her on the hard (no red shown) after my 11year project ends in a few weeks I will again apply csc b4 LAUNCH of my 50' M/V DAWN MARIEITS GOOD STUFF.

how long to put second coat on?
Really pretty quick. Just sorta slopped it on heavily with a roller
Hello shopper,I'm not sure what the requirement is, but I would apply my first coat in the morning and take a break. Then I would apply the second coat in the affternoon. You might be able to apply it sooner because it dries fairly quickly.I just need that break before tackling the painting again.
the manufacturer website lists 16 hours between coats and 16 hours before putting it in the water.
The boatyard usually waits about 1 hr between coats.
I use only a single coat every year otherwise there is too much buildup year after year. There are places that have worn off within the year but the boat is pulled out every October for winter storage. Some springs I only touchup places and do not paint the entire bottom.
Can I use micron optima over act and how to prep ?
After using ACT for years, I switched to Micron but had the bottom soda-blasted first. I don't think the Micron would adhere to any ablative paint.
I have always painted my boat with Micron Extra. I see it is no longer offered by Interlux. Can I safely overcoat Micron Extra with Micron CSC? Thanks.
Shouldn't be a problem. Check out yachtpaintforum on the internet under micron-csc-to-extra_topic414
Sorry I don't know
Yes. Use the same painting and cleanup methods. Micron CSC is a good bottom paint. We recoat the bottom every spring. Alex
Barnacles are a big problem in Salt Pond area of Rhode Island. Had been using Interlux Micron CSC on hull, rudders and tabs which worked well only on the hull. Tabs and rudders were like a magnet for barnacles. Props and shafts were too but Pettit Barnacle Barrier paint worked great this season. I traded in my boat last month for one with IPS Pods and cannot strip down to bare metal so need another route. I spoke with Interlux today and they said the barnacles on metal were due to the Copper in CSC fighting the metal tabs and rudders and not the barnacles. They told me to prime the metal parts with Primocon then paint the metal parts with Micron CF. Has anyone had experience using Primocon under CF regarding barnacles? Thank you, John
I cannot help you with this problem
Thank you for your input.
Sorry, John - I've only used Micron CSS on fiberglass
what is major difference between MicronCSC and the 66, are you in Jamestown R.I. ?
I'm in Oklahoma. I use the micron because it's good for multiple seasons. Never used anything else. I have a sailboat on a small lake. Fouling isn't a huge problem
Diff between MicronCSC and Micron Extra ? Is JD in Jamestown R.I. ?????
No, I'm in the Great Lakes. Nice thing about it though, is if you want to go from salt to fresh water, there is no problem. Also, it does fine out of the water. If you ever take it out, and pressure wash it off, just be careful not to get to close, as it can start peeling it off.
I don't know
When to remove waterline painters tape?
I put 3 coats on before removing the tape on my sailboat. Worked fine.
I would like to say this is my first time with bottom paint. I have a 1981 Grand Craft that need a fresh coat of bottom paint. After removing all of the loose paint. Ok I did the best I could, not sure you ever get it all. I applied the painters tape. Rolled and brushed the bottom paint on. Allowed the paint to cure over night. I removed the bottom tape 9 hours later. I had a great line and was very happy with my project. I can supply a pic later, I am still working on my white line above the bottom paint.
You can leave the tape on for up to 14 days but I usually remove the tape once I am finished painting. Just in case you did not get a tight edge you can still clean the wet paint from the hull.
I waited a couple of days in the Florida hot sun before pulling the tape from my boat. That worked well for me

So far love it.
Easy to apply. Looked better on the 2nd and 3rd coat. Looks nice and I'm excited to see how well it works when the boat is back in the water.

yes,yes,yes, and probably yes
MY 31' Tiara's bottom was stripped and painted with black AwlGrip in 2005. That application lasted about five years without touch up. Then minor work was required yearly, mainly involving pinholes and small areas. Since I can't buy AwlGrip in quarts I went with CSC over 2000E barrier coat for touch up. I don't know if this is the method for professional shipyards, but it works for me. Fresh water Lake Erie is my boating location.
Not another boat Bill
