Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


Well you are about to get a self-taught course on dry-wall finishing.

Glossy commercial paint, light shining on an acute angle, vertical joints, not much margin for error. If it was a dark room painted with flat white you would be cashing the cheque right now. Guy walks in at 3PM when the sun is just streaming in against that wall and those joints stick out like a sore thumb, so he grabs his phone and lights ya up.

Also look at pics and notice no butt joints. Full sheets

so speed.

metal studs - no need for strength.

tradition.

There are a number of rated wall assemblies using single sheets of drywall on either side of steel studs, some of which require that there are no floating drywall joints. But in this case it was probably to avoid butt joints.

I skim to even all that out in old houses. Lumps, bumps, ridges,... 1/8"-1/4" skim will flatten most wall defects. That's trowel work, for me.

Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


I would try this: knock it down with a pull scraper with somebody catching dust with the vac (check that it's knocked down to the tapers with a long straight edge), then try again. Just this one time.

Or hang new drywall horizontally. Use a magnet to find the screw heads and remove it gently to minimize dust.

Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


I'd have to go with Big Johnson on this one - get a good finisher in to fix it. Once it's painted, it just more of a PITA to fix, no matter which way you do things.

Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


I ain't a drywaller or painter but I've worked a lot of commercial construction and never seen board hung vertically on metal studs. But maybe that's more standard practice where you guys are.
I'm also wondering about the cure time between coats if the weather was humid at the time and also the cure time before the painter put the primer/sealer on because that really looks like a humidity/moisture issue to me. Did you have de-humidifiers/dryers going at the time? I know you guys over by the Great Lakes have monstrous humidity in the summer.
As far as fixing, you experts in this field will know more than me but realistically, is there any other way than to take it down and redo it to actually make it right?
At any rate, that is one helluva mess by the looks of it. Good luck.

Hanging vertical is common in commercial work here.

Thank you, Ernie - yes, we had fans and commercial air movers; no de-humidifier. This area is part of an existing office so A/C was running most of the time. We did not rush spackle drying time; have no idea about the painter. The painter started with primer about 3 days after we finished this room. We do not yet know what products or process the painter used.

Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


Thanks again for all the feedback; criticism we learn from as well.

Yes, GC required vertical hung boards.
Yes, for what it's worth, the darker paint color with higher sheen on the soundboard was unexpected.

UPDATE after today's visit:

There is NO lifting, bubbles, puckering nor any cracking at all.
The soundboard walls are the major issue.
We inspected with a spotlight and 4' metal straight edge over the seams.

The seams were flush despite the scary picture (and having been schooled here on the 'sloppiness' of our edges, which I don't disagree/will improve), with the exception of a couple of seams, not all, with approx. 6-10" area with approx. 1/16 - 1/8" high point, the rest were flush.

So, upon closer inspection, the darkness seen in the picture around the seams is not a ridge shadow but is instead discoloration. The lighter area around the seams are as well, or simply appears lighter due to the very visible shine there.

All of the seams, on the soundboard and most standard sheetrock walls, are shiny.
We also noted in the existing office area, which was also freshly painted, our minor patching can be seen when looking at the wall at an angle because those spots are also 'shiny'.

The client noted that the wall looks perfect when the overhead lights are on and joked about just never turning them off

Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


I finished drywalling and painting my bathroom a few months ago and had a similar problem with 1 wall with the way the light hit it from the window. I solved it with a coat of plaster weld and a skim coat of joint compound. Only other way that I could think of maybe fixing it is by spraying it with a coat of USG Tuff-Hide and then repainting.

Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


You can minimize flashing issues (which is what this seems to be by what you say) by using a primer / sealer, or just a regular sealer for the first coat.

I've never seen a seam flash light on the window side, and dark on the other side. Like I said before, if you hold a 12" knife perpendicular to the wall and you can see light under part of the blade, it isn't flat enough.

Yep, excellent advice and totally understood what you were saying -- we attempted exactly that today while we were there.

Yeah I expected that response, lol, and do completely respect and acknowledge your experience and skill exceeds my own.

As advised, at visit today we had a brand new 4' level as well as the knife and halogen spot. And just in case two guys did not correctly hold a perpendicular straight edge over the seam while shining light, checking up and down all of the wall seams, we will diligently re-attempt tomorrow and confirm our findings. It is difficult to get pictures but we'll try.

Again, we appreciate your input, thank you.

GC was not yet able to confirm if the painter actually used a sealer. I'm assuming you are saying that with the situation today, we could (or the painter could) apply sealer now before a new topcoat which would even out that coloring, doing so without skim coating first....?

Seeing as the seams are flat and you appear to need a resolve to this, Gaurdz, Stix or SW Pro Block over the paint, thin a 5 of Plus 3 to pancake batter constancy, roll "batter" on the wall using a 3/8" nap roller, smooth with your brand new 24",(or) 32" and/or 48" Tape Tech finishing knives.

Not going to work. You could put 10 coats of anything on there and it's still going to show. It might show less but it's still going to show. I'll bet your painter used PVA primer which the GC should know and it should be in the painting contract. In your defense, I'm guessing the contract didn't call for level 5 so you should be able to get away with fixing the sloppy parts and recommending they buy some horizontal blinds (to reflect the light up or down) and repaint the walls flat or flat enamel. Maybe low sheen eggshell if you're good.

Re: Help! - Why Seams Bubbled 3+ Weeks After Finish?


How big is this room? It wouldn't take much to just do two skim coats and sand. A couple guys could do it pretty quickly.

My concern would be if you are allowed a quick, but not quality fix, it will come back to bite you. You might be fine as far as this job goes, but you might not get called for any more from this GC, no matter how many times he says it's fine.

Vertical seams and that window are a recipe for disaster unless you know exactly what you are doing. Those joints are pulled way to narrow for vertical, as you now know.
