Greetings and Happy New Year. I own a 60 year old house with stucco walls inside/ out. I live in a tropical region with an average humidity of 80%. I would like to resureface the interior walls (3/4 inch stucco/ metal reinforced + multiple layers of latex paint) and my question is can I apply cement plaster over mulitple layers of latex paint or is is essential to remove it. What is the recommended preparation? I assume that because of the relatively high humidity cement is prefered over plaster. Am I correct? Thanks!

Okay I admit I'm a newbie so I need lots of advice: I have a "new" home built in 1933. Love the house, I mean love it! but I have some issues in the Living room which I need to fix. The walls have 3 or 4 random wall cracks which is not unexpected in a town with a noisy rail line. The cracks while anticipated with the age of the house has caused a dilemna. The walls seem to have a bubbled or textured surface. I know how to correct the cracks, but then the smooth crack fix will not blend in to the rest of the room. If this was a family room, I wouldn't worry about it, but being that it is the Living room, I need to have the room look correct (a job worth doing is worth doing right). Anyway I guess my question is what do you guys/gals suggest? I have thought of sanding the surface of the entire wall, but that will be a task in a 24x12 room even with a power sander. Is there a way to duplicate the surface texture? I am not opposed to almost any options. I just want the room to be done correctly.
