Paint Compatibility-Mixing Antifouling paint

[wingssail]

I have always mixed black and blue antifouling paint to get dark blue. It has worked well.

Now there is a shortage of blue antifouling paint here in Mexico.

I am going to use PCA Gold Premium Ablative Antifouling Paint from West marine. I can get black but not blue. I have a gallon of blue ABC3.

Can I mix the ABC3 with PCA Gold?

Only looked at if both were solvent based paints so they would be miscible. They are so they should be fine to mix.

That said, would try a very small batch (a few mLs) at a 50:50 (or whatever approx. volumes you have of each to form the ratio) to see if anything unexpected happens (forms a weird precipitate, etc.).

No idea what the performance will be for such a mix, but if that is what you have it's worth the test. What color did you get this time!!??

Well, it would probably work (mixing the two brands) but I think I'll use the Comex ABC3 blue that I have and scrounge up some Comex ABC3 black so I am not taking a risk. It'll cost me a bit more but that's what I have done in the past.

Some paint has copper or zinc. Mix the two together for a fun time.

Many paints have already been combining copper and zinc compounds for their biocide cocktail, not a big deal.

Neither of the products mentioned by the OP contains any zinc.
