Oily Substance On Bathroom Walls

In the bathroom i ve noticed that on certain surfaces like the part of the sink that is connected to the wall has some yellow substance in it.

Oily substance on bathroom walls. Red stains on an interior wall possibly wallpaper that may be a red mold. I have never painted these walls in the past 8 years we have been here so i have no idea what it has been painted with. The wall is an interior wall constructed of wooden studs and 1 2 inch drywall. Then i noticed it on top of the radiator.

Only thing we have done is put a metal roof on the house approximately one year ago. It looks like water has condensed on the wall but despite repeated cleaning the substance still appears brown and sticky. Concentration of water soluble paint ingredients called surfactants. On the surface of a latex paint.

We thought at first it was something from the kids spilled something and maybe didn t clean it up right maybe spilled some kind of candy or our 6 year old niece that visits and doing something. The odd thing which i cannot figure out is that a faint yellowish substance appears from nowhere and runs down the wall. It is not happening in the bathroom and the hallway was painted approximately 2 years ago. The ceiling seemed unaffected.

Then pooled on top of the toilet paper holder. This is an interesting thread. The bathroom is up against the wall to the outside of the house. Behind 2 of them are bathrooms and the 3rd backs on to a hallway near the kitchen.

Several weeks ago the walls in the bathroom began to bleed a mysterious sticky substance some sort of oil. All 4 walls in the bathroom were bleeding from top to bottom. Yes you are right it is plaster out of the 4 walls 3 of them have these oily yellow tear drops. It didn t build up it more or less pooled.

If you live in an older house that had a lot of different residents move in and out over the years there s no doubt that the place has a lot of character but one mystery that has been stumping me for some time now are these gross brown spots and streaks on my bathroom walls. Yellow sap like substance on inside walls. I wouldn t notice this on the semi gloss lavender paint but it pools on the white wainscotting below. Over the last month or so we have had random spots of sticky yellow sap on our walls in weird spots.

I have an interior bedroom wall that somehow produces a brown sticky substance that runs down the wall. We just noticed yesterday this scenario on our hallway walls outside the bathroom. Red stains on walls or ceilings may be due to mineral salts and effloresence if the wall is masonry particularly brick masonry or the red stains may be a species of mold or even a red yeast such as rhodotorula often found indoors in wet moldy conditions.
