Help with drywall stench


I handle remodeling for houses owned by banks & corps. We have one that presents a difficult problem. Mentioned in other posts, apparently, this house was built using the foreign drywall. It has a developing smell of sulfur.
Is there anyone in this group who knows of a solution other than replacing all the drywall which would be beyond the value of the house?
Any suggestions greatly appreciated.

I've seen on home improvement shows where you can also add an odorizer to your paint. They've used it to remove the smell of cigarette smoke trapped in walls.

Help with drywall stench


Thanks for the replies. What I'm hearing is that in 2005 when building material was so scarce, builders were buying material from foreign suppliers & the result is this stuff that smells really bad after a time.
I am trying to find out if anyone is familiar with it and if there is some solution other than replacing all the drywall.

This has to be the tip of the iceberg.

Help with drywall stench


You could seal the drywall with a shellac
It's what we use for smoke damage

If sealing it with a coat of Zinsser's BIN (pigmented shellac) doesn't seal the odor, then the next step is drywall removal and replacement

I like the shellac a lot better than the replacement!

Help with drywall stench


Chinese drywall can be toxic. Is the copper tubing in the A/C black/tarnished? If so, the drywall could be offgasing sulfur. This could be a very serious problem and it is my understanding that the drywall must be removed.

I heard that when the Chinese make drywall, they use filtered sewer water.
