Any Advantage to Use 2 Coats of Primer?
Hi, I am using Zinnser CoverStain over Marlite which I had scuffed with sandpaper and cleaned.
Primer looks like it's thin in places thou the walls are actually covered.
Not sure if I should do another coat of primer or not?
This is in a bathroom, so there will be moisture.

Primer is only to give the topcoat a good bond and to seal certain stains not to cover/hide imperfections. If you truly got good coverage, there shouldn't be any need to do 2 coats.
I'm not so sure about the painting over Marlite (if it's what I think it is) in the first place, but 2 coats of primer won't help...imo.

Thanks, wasn't sure on that.
Just recently, Marksr was nice of enough to guide me along about painting the Marlite.
I am doing this one exactly like I did the other bathroom with Marlite six years ago. That paint has held up nicely. Just couldn't remember if I gave that one double primer.
The one I am doing now gets a lot more use, so I wanted to make sure I am doing it the best I can.

The primer's main purpose is to provide adhesion between the top coat and the substrate. Unless you missed areas or the thin areas are so thin that you can rub thru the primer with your finger - 1 coat is sufficient.
