Primed HardiBoard?
 
I have some preprimed HardiBoard (4'x8') sheets, dull yellow in color, that need to be painted. They are supposedly pre primed. Should I trust the pre priming, or is a priming step neccesary?

I'd trust the pre priming, but then I'm always looking to cut down on the work I need to get done.

I love it, a slacker after my own heart!

I do a lot of work on the weekends, anything I can do to get to the next thing sooner is a good thing in my book.

Hardi has a list of approved paints to use and whether a primer is needed. With the pre primed stuff if you are using a a high quality exterior like Aura, Duration, MH Timeless you should be fine without needing to prime the factory primer. With that said there is not to many factory primers I do not prime over but with the Hardi it is usually unneeded.

With Hardi, you should be able to get by without a separate primer coat, but for Masonite, I coat any boards I am replacing and all the bottom boards plus boards subjected to drip splash with Seal Krete Clear Waterproofing on the front, back, and all edges. I also prime and paint all surface of the affected boards for extra durability and have not had any recurring moisture problems as determined by moisture meter readings higher than 15%.
