How to prep a bathroom walls for painting?

Paint is flaking above the shower/bathtub. How do I prep the walls to paint. What type of paint do I use?

1.you need to clean your walls very well, no dirt no nails remove everything..then you need to scrap you walls to get rid of all of the chipping paint..
2. you need to tap off your bathroom around anything you don't want paint on
3..you need to prim your walls with something like kilz
4..you need to paint then let it dry 101%
5..you need to make sure you have a wall or ceiling fan in your bathroom to control the mositure when people bath..
6..in the future you might want to make an attemp to wipe your walls down after very hot showers...

Hello, I have recently did this job, what you have to do is simple, first clean the walls down, and it is not necessary to prime, you can go to your local hardware dealer or walmart paint shop and ask them for a special paint which is anti fungal, which is easily applied on the walls just like regular paint. That way it wont peel off your walls.

Scrape as much of the loose paint as possible and then some!
Prime with KiIlz the original formula...yes it does smell horrible!
Dry for a day.Use oil paint and two coats, let dry well between coats.

Air bathroom as often as possible not to have the same problem again.

I would use TSP and water to remove the gunk. But I would also scrape the old paint off first.

First, remove the loose paint. Second, prime the wall. Third, use a paint specifically designed for kitchens and bathrooms that is mildew and moisture resistant.

use primer!

I would deal with the state of those walls and the ceiling first. If the paint is flaking, moisture has gotten into the drywall and it was obviously not primed. And in a high-moisture area, green drywall should be used, as it is made for these conditions. If this is not structural damage to the drywall, scrape and sand the affected area, prime, then paint with a good kitchen/bath paint. Prime and paint are two things that I don't skimp on. In some things, store brands are perfectly fine, but prime is the foundation of a professional paint job, and paint is the finishing touch that is probably going to be there for years. So buy a name brand. In this case, it IS better quality than some off brand that you never heard of. You get what you pay for, and a name brand will last longer than Brand X, so you're actually saving in the long run by not having to re-do a paint job sooner. The most labour-intensive and rewarding part of painting is prep: if you take the time to get quality supplies, use painter's tape to tape off non-painted areas for nice clean lines, and cover not-to-be-painted areas, it will look professional, and there will be less clean-up. Then it will not be as unpleasant an experience. Take time to do it right; don't rush the job, or the fixing up of mistakes will cause headaches and result in a poor job. So pick a day and time when you will not be interrupted, and go to it. And try not to use the shower for a little while as the paint is drying. Baths would be preferable, as there would be less steam and water splashing. Better yet, shower somewhere else as the painted area dries for a couple days. Even though it will appear dry, it's still drying for a while.

sand the flaking with a sanding sponge.then wash all the walls with ammonia and water, or a liquid sander, let dry, and paint them your favorite color in a semi-gloss latex paint.

sand the walls and use a good quaility latex paint.

scrape away the loose paint and apply 2 coats of "Killz". it is a mould and mildew killer/preventative, as well as a primer.
