I primed my steel siding with Epoxy Primer. Can I topcoat it with acrylic latex?
Follow the recommendations on the can. But generally, yes you can top coat an epoxy primer with a 100% acrylic paint. The major stipulation is if the primer is over 30 days old. It will need repriming before painting. Most primers dry very hard after 30 days and paint could have a hard time sticking to this hard surface.
