Have you had the stain on the bathroom ceiling by the bath fan?
It isn’t hard to fix! First remove the loose popcorn. Next, use some popcorn patch to fix the affected area. This can be purchase in spray or a tub. I use the tub because the spray can be a little messy. Finally, after popcorn patch is dry, paint the area. This kind of stain must be painted by a oil-based paint. Sometimes the stain doesn’t go away when using a latex based stain blocking paint. I keep a spray can of Sherwin-Williams ProBlock handy. It comes in a can as well.
I added bead board and a chair rail. A pedestal sink gives the illusion of more space. The trim is in Dover White accented with Urban Bronze (dark gray). I also painted the outside of the tub with this color. The top half of the walls are in Escape Gray. The bottom half is in Ethereal Mood. These colors were selected from the Neutral Nuance collection HGTV Home by Sherwin-Williams.
