Painting Question

[mikester]

Ive been trying to get my house freshened up since last April. It needed some work both inside and outside. The outsides finished pretty much but now we're doing the inside. Bathroom remodel, carpet, furniture and paint.

The question for painters.. I had a very mild puff back last year. A company came in and did the clean up but theres still dark areas along the ceiling/outer walls. You can notice it more in corners and along the crown molding. I have a painter thats going to do the whole inside of the house. The insurance company covered the cost.
The question is should I have the painter prime everything with a BIN type primer ? Maybe shellac based ? I painted some base trim in the upstairs bedroom and it looks dark along the top towards the corner of the room. The corner also has a bit of soot staining. All the trim in my house is Moores Regal Dove White. Walls will also be Moore Regal flats and the ceiling will be decorator white. Not wanting to see stains bleeding through in a month.

Seal it for sure, use an appropriate blocker for smoke . I'm not up on the water based stuff, I was the era of solvent or shellac based

Wall surface can be cleaned so the soot does not bleed through but it requires tedious wall cleaning, I have done it at my parents home... not worth it. Any oil base primer (BIN ect) will seal so there is no bleed through in a top coat. A seal coat can be thinned a good bit, it only need to be a complete coat, no missed areas.
With Cobbler as to latex, no water based primer or paint I have used will seal soot or smoke damage without multiple coats, like 3 or 4 coats.

a very mild puff back

huh?

huh?

Wood stove back draft.

Although interesting why insurance would even be involved.

Insurance I have is either 5 or 10k deductible. Other than place burning down or blowing away, I have no plan to use it.

huh?

What is a Puff Back? Is it any relation to a puff on a cigarette or a drag on a "Joint"?

Believe BIN is alcohol based shellac.

I've used it on some tough stains with good success but note it is extremely flammable and will leave some strong fumes during application and while drying so may not be best choice for interior of home esp if anybody in household is sensitive to this stuff.

will leave some strong fumes during application and while drying

the good thing tho, the smell is gone quick with very little linger

Carbon black from chimney soot or wood fire is tough.

probably save you the trouble of doing it twice.

in the old days, I used cheap hairspray for this stuff. (might be why I have no lungs left.)

Yes, Covid greed has not resided.. (and inflation is suppose to be 3%... ********)

Considering 5 gallons of the stuff is $181 at Home depot, retailer are still over charging. A couple of buck over $36 a gallon should be more like it.

^ on the flip side:
I bought a quart can of Rustoleum High-Heat Barbecue Black paint a couple weeks ago for $24.99 at Ace Hardware.
The last can I bought was almost exactly 12 months ago, and it was $24.99 at the same Ace Hardware.

So... .the price increases appear to have not been "across the board", which I found rather puzzling.
