Question on painting bathroom
Hi all, I have a question on painting my master bathroom in my house. First, I am pretty sure the drywall is of a regular type and isn't rated for bathrooms. My house was built several years ago,(2007) and was primed when I closed and moved in. I painted shortly after closing with a paint I wasn't really impressed with the quality of. My question is how can I properly seal this drywall where the paint will last longer, look better? Should I use something like Kilz? Should I use a special primer? Will oil based paint work better than latex? I've never had an issue with a bathroom before, but the paint from only a couple of years ago really is starting to show moisture damage and I'm concerned I may get damage to my drywall if not careful.
