Primer Under White Paint
« on: May 24, 2015, 11:03:15 AM »
This isn't a model airplane question, but perhaps model painting techniques can be employed.

Yesterday, after a horrific winter of ice dams and water leaks, I had my shingled roof replaced with metal.

Now, I have to address the many stains and spots in my white popcorn ceiling.  I previous years, I touched up leak damage (yes, there have been a few in the past) with the ceiling white paint.  They never covered well and after several coats, the stains still bled through a bit.

This time, I am thinking of priming the damaged areas to hide the stains.  Should I use silver, gray or white primer?  I already have some aerosol cans of gray.

Dick,

There is a product that covers ceiling stains quite well. It's white. Home Depot. There's also an aerosol can that sprays a popcorn fix. White again. Home Depot.

Certainly you may have an insurance claim that could pay for the stain fix?

That would be my first choice.

Good luck.

  There is a product called Kilz that is a primer and stain blocker. I believe there are several different varieties, and comes in small cans. A deep, loose nap roller will help you apply it. It has always worked for me.
  Good luck with it,

I have used KILZ before.  I have also used the popcorn spray which is messy.  The best solution has been the popcorn pellets in bulk mixed with the desired paint to the required consistency.

I don't mind paint and minor repairs myself.  The last time we had roof damage was when a tree came through the bedroom ceiling at 4:00 AM on Christmas morning a few years back.  The insurance covered repairs approaching 20 grand.  However, in making some of the repairs, unseen water damage around the foundation and structure resulted in a whole new end of the house which ended up being 42 grand out of pocket.

 I was a pro painter for years. Use Kilz stain blocker in the spay can and  not to heavy as the first coat as it will loosen the popcorn. There are special foam rollers that have grooves in them for painting popcorn. Any fast drying ceiling latex will work fine after the Kilz has fully dried. If you paint over the stains with out sealing them first the popcorn will roll off on the roller ~^ Yup I did that.

BIN and Killz are the right stuff.  BIN offers a shellac formula.  This stuff is alcohol based and fumes may be intoxicating!  Use ventilation!  Shellac has an advantage of stopping oily stains from progressing.  It also dries in minutes, on a hot day it is sometimes impossible to keep a wet edge.

Both Killz and BIN have a less odorous formula that is also very effective at stopping water stains from bleeding. 

I have used all three, and for any situation the shellac formula will work, for water stains then take your pick.  The lower priced, less odorous formula is probably just fine for your current needs.  If you have knot in trim boards that are bleeding then the BIN shellac is the only answer.
