Question from Sandy
I posted a question last week on sheetrock, but forgot to ask one of the the most important questions. Would green sheetrock be equally as safe as white sheetrock..which would you recommend?
Thanks
Sandy

When I first looked at your question I thought of a piece of green sheetrock I saw years ago that was coated with a think green waxy substance that smelled terrible.
Today that seems to have been replaced with a product with this description:
Sheetrock UltraLight mold tough gypsum panels are lightweight gypsum wallboard panels and have a noncombustible, moisture resistant gypsum core encased in moisture- and mold-resistant. 100-percent recycled green face and brown back paper.
I called US Gypsum and got from them the MSDS for this product, to find out what the mold inhibitor is.
It turned out to be Sodium Pyrithione. Here is a statement from USG about why they use it.
Here is the data sheet from the manufacturer for Sodium Pyrithione
If you wanted to use green sheetrock, it’s unlikely you would have any exposure to the fungicide after it was painted. But it’s not meant to be water-resistant.
In my bathroom and kitchen, I tiled the walls up seven feet to have waterproof walls. My bathroom is sooooo waterproof.
If you are wanting to install tile, use cement backerboard. That will firmly hold the tile in place.
