Diesel Additive on Painted Wall

[DsmToolsGuy]

Hello,

Boy I'm paying another round of "stupid tax!"

I had my diesel fuel additive bottle along with some bottles of cleaning stuff, car detailing products, etc, etc on a shelf in a small closet in my house. Not sure if the additive is that bad but it actually leaked through over time. The additive run along the shelf and then leaked through to the shelves underneath and down the wall.

The walls are sheetrock with contractor flat paint. I have gotten the shelves and supports off and out of there. Would you cut out the sheetrock and replace or just paint it with some oil based (or water based) Kilz with a couple of coats before repainting the closet? Poking those affected stained areas with my finger doesn't seem they are soft. I've had a fan blowing on it for about 24 hours.

Thanks guys for any advice, besides store that **** outside of the house and not worry about freezing !

maybe a rinse with some mineral spirits. let it dry. seal with oil base and keep your fingers crossed. probably will be fine .

Not mineral spirits, that's oily. Use alcohol, acetone or lacquer thinner, etc.. Prime with Kilz or Zinser 123, that's what those are for. I hate Kilz for every reason, but this is one place it will work well. So will shellac. Spray, roll or brush any of these.

Don't even bother with doing that great of a job with the thinner. Just get off what comes off first couple of tries. Ventilation with all this stuff !!

The additive is oil based, starter fluid on a rag and wipe down to remove as much as you can, but I'd bet it soaked through to the gypsum layer. Use a alcohol base primer to cover.
Be careful with disposal of the rags soak in water first.

My last house , one of the garage walls was splattered with a brownish substance. The seller wasn't open to answering questions . one of the neighbors told me the seller had a bio diesel making business in there and had a minor explosion one night which splattered the wall. I didn't bother trying to remove it from the drywall , just rolled two coats of oil,based kill and two coats flat white paint. No bleed through , no problem

Thanks guys for the ideas ! Sometimes I really hate having these types of learning experiences but it causes me to remember

I wouldn’t recommend using ether soaked rags to clean a wall in an enclosed space.

I agree that alcohol based Kilz will probably be adequate to seal off the stains. I used shellac to seal off urine stains and odor from the floor of one of the bedrooms in our first house. Three coats of shellac and then new wall to wall carpeting worked great.

Fortunately, it’s just a closet. I think a contractor wouldn’t hesitate to cut out and replace the Sheetrock. You can do that later if the smell persists or something.

I would go with what Zeke wrote. Or you can use one of the methods at the link to discuss it with a technician.

I used Alcohol and went fairly gentle. Some paint come off (stupid flat paint) and felt like I would just go with oil based Kilz. After drying over night and Kilz done this morning and dry it did pretty good. I think another bit of kilz and will call it a success. As Joemctag said I can rip out sheetrock down the road if need be. I think and hope this will do it after a good final coat of some good paint.

Thanks Guys !
