brown spots on spackling
brown spots on spackling
(OP)
The strangest thing is going on in my new addition. Last Saturday a contractor came in to hang sheetrock. On Monday the spacklers came and put on the first coat of compound. Wednesday they added a second coat. Today (Friday) we noticed that brown sticky spots are developing on the spackled areas only in one room.
My first instinct tells me that it is some kind of fungus. Does anybody have any input on what is causing these spots. I am concerned about the health of my family if this indeed is a fungus problem. I would also be interested in learning what may have caused the fungus to develop and how to get rid of it.

For what it's worth, I have observed mold growing on drywall compound in the bucket. Mold will also grow in as little time as a day.
Also, you should be awaree that drywall compound is available with a tint. Some drywall finishers use the tinted drywall compound after application of the initial taping. The tinting of the compound helps one to be able to see what how much compound that you are putting. The tinted drywall compound is kind of a yellowish color. However, drwyall compound is not sticky.
Suggest you get the drywall finishers back for consultation.

It could be a chemical reaction either within the compound or exacerbated by the application onto a treated material. Assuming the compound is a latex enhanced or water based material, you could be seeing a reaction result called "saponification". This occurs in latex materials when they revert to their "soap-like" chemistry.

Your concern over mold is a valid one, but also, will the area be able to hold paint without bleeding through. I'm sure the contractor would like to know. There should not be a cost for having this done by the manufacturer.
