painting the bathroom

PNW, WA(Zone 8a)

I tried to search for this but couldn't find it. Back several months ago I was reading this forum and there was talk of some kind of sealer put on bathroom walls before you paint in order to keep them from getting mildew. We have a moisture problem in our bathroom that I want to take care of this year but I don't want to rip all the wallboard out. I'd like to clean it with TSP or if someone has a better suggestion and then paint it.

Any help would be great.

Clean the walls well with TSP and be sure to rinse them clean.

Allow to dry several days before proceeding to the next step.

Prime the bath with an oil-based primer such as Kilz or Fresh Start (from Benjamin Moore).

Top coat with a latex paint.

There are additives that your paint store can put into the paint for you to repress the mildew, but I don't use them. I find that proper preparation, priming, and then top coating will do the same thing with less expense and aggravation.

Thank you so much for your help.

robinz, we had a lot of trouble with mildew on the ceiling around the shower stall. I would clean it with bleach then paint it, but it always came back.

I painted it with this,( after cleaning with bleach and rinsing well) and have not seen any mildew at all. That was about 3 years ago.

For this particular paint, they do not recommend cleaning with TSP. I have no idea why.

You can get this at Home Depot. Ginny

WoW ginlyn that sounds like just what the dr ordered. Very interesting stuff. Do they add color to it or does it only come in white? Can't wait for it to warm up enough that we can tackle that bathroom. With so little ventilation I have to be able to open windows in the adjoining rooms.

Thank you

Robin, I wanted white since it was for my ceiling, but at the bottom of the label it say's it's tintable, so I imagine you can get the color you want.
The bathroom I used it in has a window but no exaust fan and always got mildew even if you opened the window to let the moisture out. Our main bath has the fan but no window and never gets the mildew, even though the shower is used just as much.

The PermaWhite does work. They guarantee it for 5 years on the mildew. I have used it a couple times on "problem" bathrooms such us yours and have not been called back with any complaints by the customer.

I believe it's tintable to pastel colors though, unless they have come up with deeper tint bases.

Thanks everyone. For the first time in a long time I'm actually looking forward to tackeling that bathroom. There is hope now that it might turn out nice!

I just found this thread. How did the bathroom come out? ~ Suzi :)

It didn't yet. It isn't warm enough yet for us to paint indoors as I want to be able to leave the doors and windows open while we are working. We have nice days here and there but nothing consistant. It pretty much rains every day or every other day.

I'll post when we get it done.
