Interlux Micron CSC Antifouling Bottom Paint

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.

    Some Important Points
    Colors may fade or change color at the waterline. Shark White may turn green above the true waterline. Product temperature should be minimum 10°C/50°F and maximum 29°C/85°F. Ambient temperature should be minimum 10°C/50°F and maximum 35°C/95°F. Substrate temperature should be minimum 10°C/50°F and maximum 35°C/95°F.

    Surface must be dry and clean, and free from grease, detaching paint etc. Micron CSC can be applied to most popular antifouling paints as long as the old coating has been aged, is tightly adhered and is in sound condition. Do not apply Micron CSC over aluminum. Do not apply over tin-based copolymer antifouling paints.

Put it on my wooden boat.


Whidbey Island WA.


good buy but dented paint can


Consistant color. Like all bottom paints, it's a little tedious to mix completely.




Works as intended


I have used this product many times over the years, and its always worked well. This year I helped a relative with his new boat. We had it delivered with no bottom paint.I started with cleaning the hull bottom with interlux 202. Once cleaned we painted with no sand primer. Once dry (finger imprint in paint) we started with Micron csc black. This was then over coated with micron csc blue. We will now have a boat that we can relaunch for a few years without repainting. If the black starts showing through then we will know for sure we need to repaint.

Goes on Easy


I have yet to see how the paint performs for antifouling, but it was a nice product to work with. The bottom of my boat soaked up the first coat pretty well, and the second coat covered too but did not leave a uniform finish. For the areas where a 3rd coat was applied finish was perfectly uniform. I think my boat just needed it really bad. Drys quick so easier to trim out with a brush first and roll into those areas. Keep your brushes and rollers moist or in aluminum foil if not using.


Lake George NY


so far so good


Applied to a tacky coat of interlux 2000. Went on well with a roller or brush. Looks great held the tape line well. Will see how it performs on the sea life and my trailer rollers, but I sure like the appearance.




Basic paint


Basic paint which is good for in and out boats or one year service periods. When left in the water for periods of six months, it has poor grass and slime protection. Totally failed after 3 years with significant fowling.
