using kilz as primer coat

i have some mildew on my overhangs and i have scraped all i can get off.also i have gotten all the mildew off that i can .can i use the kilz stain killer,primer on most of the first coat to seal cracks etc. or am i wasting my time using kilz to cover existing paint that won't scrape off instead of using latex paint.
another question ,i was told by a person that has been in the paint business for years that tsp and laundry detergent are the same thing .what you think? i have used both and i dont think so.i have never used soilax pro. any advice you can offer will be appreciatted.

you could use an oil based primer (original Kilz), or an acrylic primer. Either way, I'd add some mold/mildew inhibitor to it before applying.
TSP (tri sodium phosphate) may or may not be in laundry detergent, but doubt it is exactly the same. Never really looked at the ingredients of laundry detergent before.
Soilax and Dirtex are good products IMHO.

You must kill the mildew dead
Dead, dead, dead
Or it will come back
Spray some X-14 on it, just watch your eyes and don't get it on your clothes
Better use some rubber gloves
Let it dry or wipe it off
That'll kill it

None of my laundry detergents contain any phosphates
Arm & Hammer, Clorox II, Woolite, Spray & Wash

I think phosphates were removed from laundry detergents many years ago.

using kilz as primer

wouldnt kilz already have a stain mildew preventative in it ,or what would you add to it .thats why i used it ,because i thought it already had stuff to prevent mildew from reappearing in it,after you kill it. is kilz or kinzer 123 stuff better for outside use .or is there something better yet?

I have run across a lot of people who have the mistaken idea that kilz kills mildew. This is not true. Although painting over mildew will slow it down the only way to kill it is with bleach [or similiar products]. Washing off the mildew is the most effective way to prevent mildew from coming back prematurely.

using kilz as primer

what can you add to the kilz to help prevent mildew from reappearing if anything.? is there anything you can add to any oil base primer to help with mildew. my wood is old ,but is in good solid condition. most of my trim has been painted with oil base paint im pretty sure.most of it has held well. thanks for any help. i have added vents to my soffits and that has allready helped immensely.

You can mix some Add-2 to the paint.

I have never added any mildewcides to Kilz, because I only use Kilz to seal stains, not as a primer or undercoater.
All of the ones you mention should work though.

The mildewcide is more important in the top coat than the primer. All mildew should be killed before painting and the mildewcide will hinder the growth of new mildew on the finish coat.

i bought some add-2. are all the mildew killers come in paste forms. makes them pretty diffifcult to get all of it into paint containers. i had no idea what form it was .i thought maybe it was crystals ..are other brands different forms? thanks for any info.
