Mesh tape, that paper shit is garbage. I still avoid sheetrock though, beaners can have that trade but I won't let a stranger in my home or be price gouged so I learned enough.
mesh tape does not completely saturate dwall with compound. mesh is garbage. 'pretty good''doesn't cut it. is good or is not. use sheetrock all purpose dark green lid compound; it has adhesive in it; with paper tape. compound, tape, press and squeeze out. dry thoroughly then all purpose base coat. the paper absorbs the compound. all purpose dries hard. or you can tape with hotmud. then plus three is okay after base coat. you really need to pickup frame to prep for hanging. use glue and screws and glue and galvy roofing nails. you can use glue and nail for shimming if you know what you are doing. just don't pound the nail in all the way till the glue is dry. nails are god for joints and seams. use a small beveled edge hammer. any joint compund other than hot mud, all purpose, or plus 3 is useless garbage.
What do you recommend far a skim coat directly over painted OSB? I know enough to get myself in trouble. My mesh tape has lasted years, no cracking or any problems but I have another project doing a tiny home (on a foundation not a trailer).
I'm no expert (besides electrical). I love building stuff though and wouldn't mind some advice. I wanna skim coat, drywalling over everything would obviously the correct way but I don't want the added expense, labor and there won't be an inspection.
all purpose dries hard and has adhesive. but to smooth plus 3 is okay. the surface needs to be fairly smooth might have to belt sand 120-150 grit then get all the debris off. i would coat with paint primer first.
