Mold along crack behind wall that was removed


Hello.

I am currently renovating a small half bath in my bathroom that we never used. Upon removing the shower I found what looks like mold in a line following a crack. Then kind of collecting at one spot the size of a softball. I have attached a picture.

PICTURE: http://www.conqo.com/mold.jpg

Here is my plan and I am looking at opinions if it is wrong.

1. Scrape off the excess all around the area.
2. Clean with a mild detergent and water
3. After dry clean with bleach and water.
4. Chisel out damaged areas and seal with hydrolic cement
5. Once dry and hardened paint over with Water Seal paint


Did I miss any steps? I am new to this issue and want to make sure I do not miss anything.

Thanks!

Looks like mold. Spray it with a 10% bleach solution, then wipe it down. If you are going to scrape it out anyway, I would skip the un-necessary steps. Clean off anything that is discolored, then patch it. Prime it with a sealer like Kilz or Zinnser. Be sure to solve the moisture problem, or it will be back. Don't use more than 10% bleach.

Well I just started working and realized I am an idiot!! This is not mold. What it is, is that the old owner must have patched a crack down the wall with a cement or hydrolic cement that dried a dark color. The beige on the wall is the water proof paint that painted over the area.

I was sitting there scraping it all realizing how hard it was and how it was falling off in rock like shapes before I realized what it is. No mold at all. Geez I feel stupid.

I am braking up the bigger areas to reseal with hydrolic cement. Then will water proof paint again.

Sorry again to waste everyones time.

Happens to all of us. Some just won't admit it.

Don't worry about it. It's not like you posted it on the internet for the world to see.
