we're new home owners and wanted to do the painting ourselves. Childs room has knotty pine, what can be done to properly paint this surface? Master BR is just paint, does this need to be primed or can I just paint over it? LR has wallpaper, don't know if its vinyl or paper, house is 50 years and in good shape, but not much has redecorated over the years. I understand that I need to strip the wallpaper, backing and wash any remaining glue off. I've read about using DIF, fabric softener and white vinegar to help in this process, but I need to make sure the wall is clean afterwards. How wet can I get a wall? Can I get it to wet? does this need to be primed before painted? What does the term "Cut in" mean? I read it a couple of times in other post.

I have a couple of (probably silly) questions related to painting a bathroom: First, would it be better to wait until paint is completely cured before using this bathroom for showering (there is, of course, another shower available :D ) ?? Just wasn't sure if the humidity would adversely affect it somehow while it cures. It was painted 5 days ago with a Satin finish paint. How long is cure time? Second, when painting around a commode tank, what is the best way to get that part of the wall painted? The tank is probably less than inch from the wall, so even the narrow rollers won't get back there. I hate to leave that area back there unpainted (though it probably wouldn't be visible) but I have no clue otherwise how to get back there?? Thanks in advance!!
