Looking for a quick'n'dirty solution here-
Situation- 1960 cookie cutter, typical 5x9 bath. Sitting on the throne yesterday, look down and notice a vertical crack in the wall facing me, very close to the outside corner where it abuts the mud-bed tile job around the tub, down at the bottom near the floor. Start poking around with a fingernail, and determine that the lower edge and corner there has gotten wet and soft under the paint, either wicking up from floor, or from overspray soaking through defects in the grout and edge caulking.
I can switch to the other bathroom for a week while this drys out. And yes, I know the proper repair is to remove all the mushy stuff and build back with new. However, the entire bathroom really needs fresh drywall due to 'redecorating' done by previous owner, which consisted of mechanically scraping off wallpaper and painting over. (Sort of looks like knock-down textured plaster.) And if I'm dong that, may as well replace fixtures and vanity, etc. In short, it needs a gut job, which simply ain't in the budget this year (money or ambition wise). Maybe next year. (I'll probably hire it out, other than maybe doing the demo myself- my drywall skills are sub-par, I've never done tile, and I don't have the tools for plumbing.)
So, I really don't want to open this wall any more than I have to, right now. What is the best material for a spot repair, after raking out the loose particles from the crack with an awl? Vinyl spackling compound? And what is the best thing to coat the grout lines in the area with, to keep water from seeping through? A thin layer of tub caulk is all that came to mind for that one. Don't care if it looks perfect, just so it doesn't look hideous, as long as it will limit further damage until I can afford to have the whole room redone.
