Yellow sap like substance on inside walls over the last month or so we have had random spots of sticky yellow sap on our walls in weird spots.
Oily substance on bathroom walls.
What is happening in your bathroom is a common paint problem called surfactant leaching the following is from the paint quality institute.
It didn t build up it more or less pooled.
We have the wallpaper looking wallboard stuff.
The bathroom is up against the wall to the outside of the house.
I have noticed in the bathroom after recently painting steam seems to leave an oily golden yellow residue dripping down the walls.
Then pooled on top of the toilet paper holder.
I have tried leaving the window open when showering and even leaving the bathroom door and then both bathroom and bedroom doors open.
They appear on external and internal walls.
That old of a home would have oil based paint and a varnish on the walls.
I have an interior bedroom wall that somehow produces a brown sticky substance that runs down the wall.
A few years ago we used kilz primer and painted two of the walls in the bathroom.
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.
It looks like water has condensed on the wall but despite repeated cleaning the substance still appears brown and sticky.
Then i noticed it on top of the radiator.
Started noticing this same thing so we never painted the other walls.
What can i do to stop this.
Is it something that is leaching out of the paint.
The condensation causes all the foreign material that is on the wall to coalesce into the water droplets.
Having just cut a hole through the dry wall i can confirm that there are no leaks from the.
The drips are always on paint.
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.
The wall is an interior wall constructed of wooden studs and 1 2 inch drywall.
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.
Over the past few years i have found a number of oily yellowish drips in all areas of our home.
The drip can start from.
I d say it s from condensation and the odd collection of goop is from the wall never being completely washed or painted for who knows how long.
It would be alot of work to remove it.
