Is it normal for primer to show thru dark paint on first coat?

Autumnknight

I am in the process of painting my exterior window frames around my house. I posted earlier in different threads about caulking and fixing weather checks.

I primed the repaired spots with an oil based white exterior primer. My window frames are two colors, a light green on the outside frame, and then a dark green on the inside frame. When I put my first coat of the dark green over the primer, I could still see the primer thru the green paint. I then tried putting some more paint on the brush, but then it was tending to run in a couple of spots.

So, am I doing something wrong as I am painting? I am using a Purdy brush btw. Or is it normal for white primer to show thru on the first coat? The exterior paint is a water based paint.

Thanks!

Totally normal...that's why paint manufacturers typically recommend 2 coats. A tip...when using primers, get them tinted to the color your working with, then you wont have a hard time with them showing through! It's a popular trade secret...

What brand/line of exterior paint?
Some show more than others, and some don't show at all

After reading one of the other threads about paint brands...I almost hesitate to say....the dark green paint is Behr ....

I had bought Pratt & Lambert semi-gloss for the light green (since it was highly rated in CR), and then bought Behr semi-gloss for the dark green. (My windows are light green on the outside frame, then dark green on the part surrounding the glass).

I used a brush, and when I applied the dark green, I could see right thru it to the primer. I understood the other post about using tinted primer....but this weekend I realized that even when I painted over the light green (which is already tinted), it showed thru very plainly as well.

It took 2 coats, and in a few spots, 3 coats, to hide the lighter colors completely.

My next can of paint will be Sherwin Williams or Benjamin Moore....

Yeah that's about right
You can need 3-5 easily with the Behr
If you get it to cover in 2 your doing well

The best covering exterior paint in SW's Duration
Yes, it costs twice as much as Behr
But if it covers in one coat.....well.....
