and then should I paint with Kilz and then oil base paint? what should I do to not get mold anymore in the bathroom? thanks
please let me know how much bleach? how much water?

the most important thing to do is to make sure you have a ventilation fan that is adequate. some older homes dont have a vent and because of that moisture stays trapped in the room from taking a shower. It is that moisture that is the basis of the mold and mildew.
Have a contractor install one for you. Or a really handy friend if you dont think you can tackle the job. Since it involves electricity, youll want to make sure it is done correctly. Kilz is fine and bleach water will kill the mold, ( i use a 25% bleach 75% water to do the job myself ) but they are only treating the symptoms. The disease is lack of ventilation.
One other thing that ive seen in my many years as a contractor is that sometimes the ceiling above the bathroom is not insulated very well in some spots, or all of it. What this does in single story homes is allow for warm air to be "drafted" into the bathroom and that can also cause condensation to form. This last example is unusual but ive seen it a few times. And Yes bleach does kill mold. Bleach kills almost all micro organisms. BUT, and this is important, it will not effectively kill the roots of mold in most porous surfaces, such as wood. It will kill both mold and mold spores (roots and all) on hard non porous surfaces such as glazed tile (not natural stone tile, thats a porous surface)

When I moved into my apartment I noticed that under the floor where the tub meets the floor there is a growth of mold that seems to be growing. I was wondering if anyone had any suggestions for cleaning this mold out from under the floor? Realize as well that I cannot do too much "construction" since it is a rented apartment. Thanks for the help.

I would use bleach diluted with water on the mildew. I hope it is not under the floor if it is the landlord needs to repair. Especially if you are allergic to mold/mildew. Also I use Oda Ban this is a good product for mildew too and it is good with bad odors it will kill germs too. I use it on stubborn stains in my own home.

Your bathroom wallpaper is the ideal spot for black mold to thrive in. First off, the bathroom is one of black mold’s favorite places in the house. It’s probably number one. This is because it’s humid and, unlike water damaged parts of the house, the bathroom keeps getting steamy and wet repeatedly each day.

Mold likes the wallpaper in particular because it’s a nice, porous surface. This makes it easy for the mold to get there in the first place, and “breathe.” Black mold needs a little air to thrive well, but it also needs the darkness. Mold that hangs out behind your bathroom wallpaper actually stores water, like a mouse in its hole with a chunk of cheese. This keeps it alive and going behind your wallpaper.

Finding The Enemy!

Most people don’t know they have black mold behind their bathroom wallpaper until they’re removing it. Mold is sneaky, and you can’t see behind your wallpaper. If you suspect that you might have bathroom mold, you might want to get your bathroom inspected. It’s difficult to be sure by yourself, but if you have sudden nasal decongestion, trouble breathing or other mold-related health symptoms when you go into your bathroom, you definitely have a problem. And, if you can’t see the mold anywhere, there’s a good chance it’s behind the wallpaper.

You vs. The Mold: Getting It Off Your Bathroom Wallpaper

Unfortunately, the only way to rid yourself of the evil mold behind your bathroom wallpaper is to remove the wallpaper itself. If you decide to do this, there are some precautions you must take:

- Put plastic around the bathroom as if you were painting. Remember that mold is toxic stuff and the spores can get anywhere and cause you even more trouble. Imagine that you are cleaning up toxic waste somewhere, and you don’t want it to touch anything!

- Make sure the room is well ventilated. If you’re bathroom has no windows, at least run the exhaust fan. When you start stripping that wallpaper, the mold is going to go everywhere, so you want to make sure there’s plenty of air circulation.

- Wear protective gloves and a mask. You don’t want it to touch anything, including YOU! The bigger, the thicker the gloves, the better. Also, look for a mask that is especially made for mold cleanup. Some masks just cover your mouth and nose, but at your local hardware store you can find special masks intended for mold removal.

- After you take off the nasty, moldy wallpaper, save it in plastic bags before you throw it away. As I said before, it’s important to not let the mold touch anything. You also don’t want the spores to be airborne.

Keep It From Coming Back

Even more important than cleaning up the mess is keeping it from coming back. The bathroom’s always going be a popular spot for mold, but here are some things you can do:

- Buy a humidifier to keep in the bathroom. Use it as directed, and turn it on after showers to help keep the bathroom from getting too moist.

- Make sure you turn on the exhaust fan when you’re showering. You might want to run it a little bit afterwards too.

- You can buy woven wall paper that is designed to keep off mold and mildew. Look around at wallpaper suppliers and tell them what you’re looking for.

- Some wallpaper dealers also sell waterproof wallpaper. You might want to check these out, but make sure it’s the real deal. Ask the dealers how exactly it keeps off the moisture. Regular vinyl wallpaper isn’t always “mold proof.”

- Instead of wallpaper, paint the bathroom. Although mold can grow on paint, this will greatly reduce your risk of getting a mold infection behind your bathroom wallpaper.

Not only is bathroom mold ugly, it’s also bad for you! That’s why it should not be ignored no matter how common it may seem. If you notice mold in your bathroom, you must take action right away as mold can multiply rapidly and can quickly get out of hand.

If you do have mold, don’t despair because are lots of bathrooms that have mold, in fact it is actually rather common. That’s because mold loves a moist and warm environment, so what better place to grow than in your bathroom? While a little bit of mold can easily be wiped off, letting mold build up can be problematic as the more mold that you have, the harder it may become to get rid of it.

If your house is like so many others and has some bathroom mold, here are a few things you can do to battle it:

The first thing you should do is to check if your drains are draining properly. If your water is not draining properly, then this leaves your bathroom moist for long periods of time thus creating an environment for mold to thrive in. Also, check for leaks under the sink – a drippy pipe can create an inviting environment for mold to take hold inside your vanity where you may not even notice it.

Another thing you can do is to minimize the number of items that you have in your bathroom. This means your toiletries such as shampoos which are almost empty, facial scrubs as well as soap cradles and toothbrush cups. All these items are potential breeding grounds for mold. Plus with more items cluttering up the room, you are less likely to be able to spot mold on any surface.

Of course, cleaning the bathroom is a must. Remember to clear out all the items inside your bathroom when you clean it. Use store bought cleaning products that are proven to work and use it on all the soiled, moldy and damp areas within your bathroom. Use a sponge when doing so for brushes tend to leave scratch marks and make bathroom fixtures look aged. You can use vinegar or tea tree oil to get rid of mold if you are opposed to harsh store bought cleaners. Also, if you do have mold, be sure to dispose of any cleaning materials used to eradicate it as the mold can be on your sponge or brush and then could be transferred to another area of your bathroom.

You might also want to start doing small repairs and remodeling jobs inside the bathroom. Replacing old fixtures such as the faucets, old tubs and the shower itself would help prevent mold and remove the mold that has accumulated on these surfaces as well.

Taking the time to inspect your bathroom periodically will help you be able to notice mold when it first starts and make your job of getting rid of it that much easier. Unless your mold problem is excessive, battling bathroom mold is not that difficult – it just takes a little bit of time and elbow grease!
