This is in a new addition mud room so we used an eggshell finish as you can tell if you can zoom in on the pic it's like the paint just ran right off the spots

What did you use to fill the holes?
Something with silicone in it perhaps?
This is very odd indeed if not.

Please put your location into your profile-----

I believe what you have is condensation forming above the screw heads--and it is washing the paint off those cold spots---Has it been cold?.

new drywall


Thanks for the help....made a materials run this evening for the tile. The location of the photo is in the corner where the new addition abuts the existing structure. We used regular drywall compound on all of it. we have 2 corners that have this issue going on. one is on the old structure side the other is on the opposite corner where the new addition goes out onto the deck and there is nothing that it touches....all this has me puzzled/stumped. The drywall had about 3 days to cure after the final coat was put on before it was primed. My confusion is why only the screws seem to show when the same compound was used on all and they are under tape and compound. It has been cold here temps in the 30's (avg) but the heating is in place and has been running plus we had a propane fireplace type heater also running in there while we were working on the drywall because of the fact it is winter here.

I've seen that exact problem---high humidity from all the paint and mud--cold spots=condensation

Try just touching up those spots and putting a fan on it--it will dry.

I had a house with a bad moisture problem caused by a badly vented roof--we had to cook the walls with a torpedo heater to keep the paint from running off the corners.

Thanks Folks, we have had high moisture....snow/rain/cold. I'll try giving it a couple more days to cure on out then try touching up the spots. I really appreciate all your help! I do think next time we tackle a project like this it won't be in the dead of winter....brrrrr

I have never heard of a white bleed through. But there are a number of things it could be, and not being able to see it first hand, I would assume that maybe the primer wasn't of good quality or the application wasn't thick enough. In that case more paint won't usually help. It is the primer sealer that seals. I have used Parker pro prime for 30 years because it does the best job and isn't outrageously priced. I would first try repriming only where needed and then repainting. If it still shows then you will need to get some kilz to seal it with and repaint.
