I have a 3 season cabin in PA. We have torn out old homosote and would like to cover the studs with something else. The cabin sits through all kinds of weather and gets aired out regularly in the summer, but no so often in the winter. We occasionally use a propane heater and/or fireplace for a fall or early spring weekend. There is no insulation. It is wired for electricity and keeping the studs exposed is not an option (although that might be best for the cabin).
Would moisture resistant wallboard be a good option to cut down on mold/mildew? Is there still a visual texture difference between the joints and the wallboard surface after installing?
You won't stop mold except with good ventilation. I have seen it on greenrock, durarock, concrete, wood, paneling, and other surfaces I can't remember.
If you think about it most sheetrock is textured and painted. Yet mold still grows on it. It has no bearing in what kind of sheetrock is underneath.
Any sheet rock would be fine.
Just move furniture away from the walls, open up cabinets to allow ventilation.
Get a small box fan and hook it up to a timer that will turn it on one a day for an hour or so. That will give some circulation. Also having some vents in the wall would help in keeping moisture from building up.
My idea of a perfect day: No where to go and all day to get there.
