Okay, we've lived in the house 5 years this coming July and the house is approx. 43 years old. This past winter nearly 80% of the drywall screws have begun to show their ugly heads (pun intended) through the paint. The are showing up as small, dark circles and in a few places actually appear to be slowing coming out of the wall. I remeber several years back, when this was not even a thought, I heard or read of this happening and a fix for it. Now that I need the fix, I cant find it or remember it. Does anyone else know what it is?

Also, I am in need of two, 8' long, pieces of 8" diameter pvc pipe for the slip at the marina. Anyone know where i can pick this up? Home Depot and Lowe's show nothing in this size.

I've never seen screws start to show like nail pops after drywall work.

If that happened to me, I would check the length of the screws because they should be long enough to penatrate the joist/stud by at least a 1/2 to 3/4 inch.

If the screws are too short, back them out and use longer screws, mud over the holes, sand then paint again. You may have to place the new screw and inch to either side of original screw whole so it has fresh drywall to grab.

In a house that old they didn't use screws for drywall I thought???????

I thought the same thing Rerun. I cant see a screw pulling itself out like this, and it all happened in the last 4 months or so. I was even thinking of just using a block of wood and pounding them back in, a coat of KILZ and then repaint the walls. As much as we love this house, she is going up for sale as soon as we are done with a few fix jobs and moving closer to the water.

Wow thought houses in 50 s or 40 were plaster. Mine was. Might as well do it right and drive a new one in on top or next to old one. Then mud over it. Can you get old one out if so unscrew it.

Try warren pipe for PVC. Or Macomb pipe on mound and 15 mile. You're in sterling hts right? Macomb should have it. They will order it for you if not. Or D.F. Burnham pipe and supply off 18 and Vandyke.

did you re-do the drywall? strip the walls and put up new sheetrock? or is this the original wall material that you painted over and is just now starting to have these problems?

hard to believe it would be the original wall material that after 43 years the screws just start popping through, if this is the case my guess you have a severe moisture problem, is the screw pops isolated in one area, on an outside wall, maybe caused by ice daming and water backing up behind the wall, if its an interior wall, im not sure

sounds very weird, post more info, or a picture

I would have to think that they are nail heads, too. Screws won't pop unless they unscrew out of the wall. If that's happening on it's own, you probably need an exorcist.

If they are nails, I'd agree with Goose that there is some sort of underlying moisture problem causing the wall studs to swell or contract for the nails to work themselves out.

I was just helping a friend of a friend hang drywall this past weekend and we were doing a room in an addition. Where the wall met the ceiling his Dad didn't want me to put any screws any closer then 6 inches to the wall/ceiling pieces. His dad has been in construction for 30 some years and he said that any areas where moisture is a possiblity (roof line, wall seam) he said if you put a screw there, there is a possibility that the screw head will turn the drywall black there from the moisture. I learn something new every day

i redid a bathroom and used longer screws and on the walls that were on exterior facing walls the screw heads would get colder than the rest of the walls, cause of the exterior wall being colder and the metal conducting the cold better

well , when you took a shower the water first condensed on the cold screwheads, even though they were covered with mud, primer, and paint

i had dots on the exterior walls of water and eventually the paint cracked up around the water marks

i had to chip out the old mud and use a thicker mud to redo the screws on the outer walls

The main wall with the problem is an exterior wall, right above the front door. Unfortunately it is also appearing throughout the upstairs in the hallway and bedrooms, especially on the ceiling where the drywall was hammered to the studs. This should all be original wall board material from when the house was built in 1961. It could very well be a moister problem as the main bath/shower is on the second floor and there is no exhaust fan in the bathroom, just a large atic fan in the hallway just outside the bathroom door, and we very rarely run it. Its not uncommon after a hot shower or bath to see all the windows upstairs steamed over just as bad as the mirror in the bathroom.

As for pics, I'll post a couple in the next day or so, have to get ready for work right now.

Thanks for all the input.

Bathroom
In Canada we use a Blue drywall in Bathrooms 5/8 th with
1 1/4 inch screws.Do not use ordinaly drywall it will rott
with the moister.I agree with the person that said it was Nails
screws would not turn out .Your drywall may have moisture in it
and has rotted.If this is true rip it out fix where the water is coming
from then Insulate & put up a Vaper barrier.You are very likely loosing
a lot of heat.By doing this it will inprove your Heat bill.
As for your 8" Pipe any Plumber will have it .

Once you read this post it will self distruce.
Never tell anyone I told you this.LOL
