Kilz is nasty stuff, I refuse to use it anymore, and am not in the mood to put on a gas mask. Ha. Lowes has 3 levels of semi gloss interior, and I use the middle grade. I prefer semi gloss because it's washable when it dries, and we always have children in this house. It is also washable off the brush, unlike the old thick enamel everyone used to use for the kitchen. We don't have any mold in the upstairs bathroom, or anywhere I've seen here. Husband is allergic to mold, so we are nick picky about that, and use dehumidifiers when we need to. That bathroom was put in just 4 years ago, and we only put one coat of paint on it. The kids use the upstairs, so it was just looking a little hinky, and needed a total cleanout. Theyve be using the downstairs shower and bathroom while this is under construction. We have our own new handicap bathroom off the bedroom build on. The walls and ceiling just needed another coat of paint, a new light fixture was installed since the kids broke the last one. I need to paint the floors two coats, another coat on the ceiling, and a wall by the sink. Then rehang the curtain and the shower curtain. No trim was ever put up or baseboard, and I need to buy some, something thin enough for me not to use a nail gun with, since I don't have one, and someone ok enough not to require a slanted corner cut. Then I'll paint that white, along with everything else.
