BLACK MOLD

I have just noticed on my blog. A young lady asks me how to tackle a mold problem she has just gotten after a roof leak in her home. She went on to say ripping out the wall/ceiling isn't an option, because of the cost. Then went on to say that Kilz is also expensive and was not effective at any rate.
I will answer the last part first, but first I want to thank her for sending me her question. Now!
Kilz is a product that is in my opinon is very good, but is does not kill the mold. It kills the stain. There are other products like whitealac. This is a paint/shellac product. This does the same thing. Long before this and any other of these products, we in the trade, just used shellac. It will cover any stain whether it be oil, water or mold. Then allow you to paint over it and the stain will disapear.
THIS IS of course, IF the problem that caused it in the first place has been corrected. A water leak is the worst of all. This is because sheetrock/wallboard has just the right make up to allow black mold to fester and flourish. But the things that must be presant for this to happen in the first place is MOISTURE. Not just once, but on going moisture, like a little leak on a pipe or in the roof. TEMPERATURE. Mold grows better in the warmer month or where there is heat.
In this case there is a roof leak, you stop the leak and now you want to paint the stain. You first must have it dry out fully. If there is insulation behind this wallbord. It will act like a sponge. It will take forever to dry out and just give off more mold spores while it is damp, This is the reason that most say cut out the wet part, patch it with new wallbord/sheetrock and mud it and paint. If this is not a option for one reason or another, WAIT for the area to get fully dry and then cover with shellac and paint to match.
To kill the mold in the first place. Mix in a spray bottle a mixture of water and Clorine Bleach, 50/50 and spray it directly on the mold stain. Clorine is the only thing that will KILL mold, When this is completely dry you can paint it with the shellac . Let it dry and paint to match. This is very time consumming and an eyesore to look at. BESIDES not being healthy to have around while waiting to be dealt with. This is another reason most people just cut out the wet area and go from there. Hope this was helpful.
