I have some fiber cement board that I need to paint on the side of my building. Painters and manufacturers recommend 100% acrylic paint but I need to use solvent based paint to match the rest of the concrete building that's not covered by fiber cement board. I live right next to the ocean so I'm using solvent based paint to prevent mildew and stains from the ocean spray and salty mud around my home. It will have to be very durable and able to be washed occasionally.
I read
here and
here that you can use water based/acrylic primer and then topcoat it with oil paint.
I just wanted to make 100% sure.
Can I have input from some people?
Additional Note: I already bought the Solvent Paint and can't return it. So I will test it in a small section but I'm not sure what to "look for" when trying to identify if this will be a NO GO. So, what to I look for to make sure I can proceed?
