What would cause a tan substance to "seep" from an interior latex satin?

Question

ColorPlace Paint
Only the top two feet of the wall
It is dry, and wipes off with a wet rag.
Looks like I poured CocaCola on my wall and let it dry.

I gutted the bathroom all the way down to nothing but the studs, replaced and finished the drywall, put two coats of kilz, and two coats of paint. The last coat of paint was put on about a month ago. It seemes like it happened over the past seven days while I was offshore.
I've crawled all around my attic suspecting water, there are positively no leaks (especially with the rain lately) and my house is elevated off the ground making water not an issue.
I think it is defective paint.

Answer 1

I had the same problem in my kitchen. - New drywall, primer, and paint - then the mysterious brown stain. The stain was also at the top of the wall, but in the general area of the drywall seams, where there was the most joint compound. I assumed it was caused by the moisture in the joint compound - i.e. I didn't let it dry long enough, or maybe it was defective or not mixed properly. A second coat of paint a week later, covered the stain and there has been no more seepage.

Answer 2

You are getting water infiltration from the outside, and its making what ever is in the wall, bleed through.

I will assume its in a basement, with that much water infiltration, so, there are a few things you can do...

Make sure your gutters and downspouts are clear.

Make sure the slope of the land is going AWAY from your home! So that water is carried away and not setting in puddles around your exterior foundation.

Fill in any cracks in the sidewalk with an asphault filler, (roofing filler in a caulk gun is the best as it will 'spread out in the heat', and seal good).

If you have bushes, remove them near the foundation as it collects water and will actually break down a wall, or start to "root" into a wall, and crack it. (Plus termite damage is a great possibility).

Now, if after all this you still get "wet walls", then dig a trench a foot wide and a foot deep all along the foundation. fill with pea gravel, to a dept of 2", then lay a pvc pipe with holes in the trench. (Put a fiberglass mesh over the holes so that you dont get anything in the pipes and clog them). Now, join all the pipes together, and have one, going to a down hill slope leading away from the foundation. Now, fill the rest of the trench with river gravel, and top with an inch or so of soil, and plant grass over it.

This should redirect the water away from the house and you wont get the "wet spot" all along the walls...

I wish you well..

Answer 3

You might have to use a sealer (like z-prime) and repaint if the bleeding doesn't stop. Previous answer, could be nicotine, might also be some sort of mildew residue or an acid product, like the brown foxing on old paper.

Answer 4

is sweat building up inside the room somehow? like in a bathroom with steam

Answer 5

your walls should be cleaned with tp ( a cleaner ) before you paint . the brown must be cooking grease or oil from when you fry food.

Answer 6

it is probably nicotene from a previous tenant or owner.
