Compound Failing In Bathroom


I completed a full bathroom gut/remodel about 8 months ago and recently received a call from the owner to look at a couple drywall issues. On the ceiling it looks like the compound is separating from the screw heads and some of the tape. I use the same method for every bathroom which is MR board glued and screwed with Great Stuff foam adhesive, black top compound to set the tape and then lightweight for the finish coats. I would have primed with either Zinsser 123 or Benjamin Moore SureSeal and then 2 coats of Benjamin Moore ceiling paint. The screws haven't "popped" since it is glued and I checked it isn't loose. The compound is just falling out of the screw heads. The owner insists they are running the bath fan but I obviously can't verify this. There is staining on the ceiling from moisture along with streaks down the walls. This problem is not occurring at any walls. I will probably end up fixing it either way to avoid confrontation but want to know if I am doing something wrong with my methods???

Re: Compound Failing In Bathroom


Wondering you have any gaps around the bath fan, behind the trim. Maybe the excess moisture is affecting the wood.

Re: Compound Failing In Bathroom


It looks like it’s more of a moisture problem than anything else. Either the fan is underperforming due to size, ducting or lack of makeup air or they aren’t turning it on and letting it run. Second, not a fan of LW compound. Third, if we are taking that BM waterborne ceiling paint, it’s nice stuff but I’ve noticed it’s finicky some times.

If you want to repair this to keep a good relationship with the customer, I think I would skim and sand the bad spots. Prime it all with Gardz and then paint the ceiling with Aura Bath and Spa (matte). Although I always like a dead flat finish on ceilings, once you leave the job you can’t control how hot of a shower they take, for how long and if they run the fan or not.

Re: Compound Failing In Bathroom


I've seen plenty of issues driven in part by leakage at the fan/duct connection.

Re: Compound Failing In Bathroom


Don't do anything different with baths in new homes than in any other room.

Invariably, when I get calls about streaking on walls, they have kids that have reached puberty and use all the hot water.

Oh reminds me: these are the same families who will claim their water heaters are defective.

Re: Compound Failing In Bathroom


If those boards are glued on well, take out all the screws where the compound popped off.

Re: Compound Failing In Bathroom


X2 on the light weight compound, donít like it at all. Donít like the pro form black top either, only used it once . USG green top for me , it seems to dry harder .

Donít know if thatís the problem . Iíd guess the moisture on the walls with uncured paint .

Re: Compound Failing In Bathroom


As far as I’m concerned there’s no such thing as too long a shower or running out of hot water. It just has to be understood and planned for and managed.

Yeah, I'll be damned if I'm going to let USG dictate how long I spend in my shower.

Always green top. That aura matte doesn't look bad, I don't think. I used it last month and I thought it finished very well. It also makes customers happy because it says bathroom right on, so clearly I know what I'm doing.

I thought that's what the number on the EasySand bags was for? I went with 90 because I like long showers.

Setting compound for at least first coats followed by AP. So far, so good. Got away from light weight a few years ago. Its scars too easy until primed and sands away if not careful.

Re: Compound Failing In Bathroom


Thanks for the responses. I started the repair this week and found every screw which had failing compound was rusting so I replaced the screws as recommended. Setting compound first coat, regular compound finish coats, Gardz primer and then Perma-White also by Zinnser for the final coats. I also bought a good moisture meter and found between 14% and 16% in the sheetrock... I'm hoping the owner runs the fan after this repair which I don't think I would consider warranty work but it's better than a bad review I think? Lesson learned is I'm going to add a couple more lines to my contract/warranty!

Re: Compound Failing In Bathroom


any chance you checked the operation of the fan? the flapper can get stuck.

recent remodel I talked the customer into an automatic (humidity sensing)
exhaust fan. It HAS to be in automatic mode, so it's not fool proof, but better than a fan not being used.

Re: Compound Failing In Bathroom


I always wrestle with wiring shower lights with the fan to force the issue.

Re: Compound Failing In Bathroom


Problem is, running the fan just while you're in the room only reduces the moisture; it doesn't fully dry the area. General recommendation is to ventilate for at least 20 minutes after showering. A timer is really the only practical way to do that.

Still, wiring them together beats a blank.

Wire together on a timer.

Re: Compound Failing In Bathroom


Still depends on the HO to set the timer, so I doubt that would be any more effective.

I could rig a setup to activate the fan when the light is turned on, and automatically extend the run time after it's turned off, but so far haven't encountered anyone willing to pay for that. Not to mention the logical objection to running the fan when you just run in to pop a pimple or whatever.
