I am in the process of painting my bathroom. It was recommended to
me by the Home Depot people to use good quality semi-gloss latex to
paint the walls. I want to make sure that moisture does not get to
the sheetrock underneath the paint.
Is there any reason why I can't use exterior semi-gloss paint in my
bathroom? It would seem that the exterior paint would be excellent in
the bathroom as it was intended to handle the tough weather conditions
outside. I happen to have a fair amount of exterior white that I
would like to use up.
Thanks, Al Kondo
Use a couple coats of a good oil-based primer, then top-coat with two coats of
anything, and your sheetrock will be quite adequately protected.
There are several reasons why you should not use exterior paint indoors.
First, exterior paints contain mildew inhibitors. They used to use mercury;
I'm not sure if they still do. But in any event, you DON'T want these
chemicals outgassing into your house.
Second, exterior paints are designed to "chalk" as they weather. This is
definitely undesirable inside your house.
Third, exterior paints are formulated to be more flexible than interior
paints, because they are subjected to a much wider range of temperatures. This
means that they don't dry as hard. IOW, indoors, they'll always be a bit soft
It might seem so, but that's not the way it is. A good-quality interior latex
paint is plenty good enough for your bathroom. (Hint: you won't find good
paint, or brushes, at Home Depot. Try a Sherwin-Williams store.)
Then paint your garage white. What you propose is false economy. The cost of
the paint is a tiny fraction of the true cost of a painting project. Forty
bucks is more than enough to buy paint for a bathroom. The real expense is in
the time and effort needed to do a proper job of preparation: cleaning the
walls, patching cracks and holes, removing switch and receptacle covers and
other hardware, and so on.

Some interior paints also contain mildew inhibitors.
"Soft"? "sticky"? I wouldn't say that.
False. We can argue the religious argument about what type of paint is
best, but if anything, a Home Depot store will carry *better* brushes and
rollers than a Sherwin-Williams store. Try Purdy or top end Wooster
brushes, and Purdy rollers - woven ones (not knitted) for less lint, with
beveled edges, such as the Purdy White Dove.
