Hello all,
I am redoing a home I just bought, the walls are plaster. I just skim coated the entire house with 20 minute and then compound. The day after I finished, these brown spots started to appear on the ceilings of the bedrooms (but not the kitchen ceiling or any walls). There were only a few spots in the morning, but after 8 hours, the ceiling looks like this..
I have not primed yet, and was thinking to stainblock with some Killz oil based.. and then prime with Killz water based.
Has anyone seen this before? What's the cause of it? Thanks in advance. I am hoping to paint later this week, but this just totally threw me off!
