I stripped my marble fireplace with Peel Away 7 and the vertical process made some of the liquid seep onto my parquet urethaned floors…
There are now black spots on the floor, as if some of the urethane had been stripped.
Does anyone have any experience with this- or ideas on how to restore the blackened sections to their original state?
I am thinking of sanding the area and then re-coating it with urethane…
I had that problem with PA1. I thought 7 was a lot milder. Anyway, you should try sanding first, then oxalic acid if the dark spot is still there. Then, re-poly as needed. PA is tough stuff and it’s really difficult to keep off floors if you’re doing door frames, especially the steel ones popular in the late 20s early 30s. The paint just sort of slides under and down…
if the wood has turned blackish, and won’t sand out, you could try oxalic acid. This is a form of bleach that takes out discolorations but doesn’t really lighten the wood itself.
Just read the label instructions, and wear gloves. A dust mask is a good idea also.
I spilled rubbing alcohol on my door saddle which has a water based polyurethane on it….left white spots….I used regular toothpaste to “buff” the marks out…it worked
Also, years back, I spilled nail polish remover on my parents’ nightstand…..well, my grandmother got the stain out with toothpaste, also
Give it a try before you use sandpaper
Call the company and ask. They are very helpful and will know how their product interacts with wood and poly.
You will probably have to sand it off. As for how much sanding, I can’t say. Also, you will want to try to finish off with the same grit paper as the floor was finished with, probably 100 grit (though maybe you won’t have to go all the way to the wood?)
If you do go all the way to the wood, you will want to try to use the same sealer they used, if any. It could be an alcohol based sealer or even reduced poly (if it is oil base; 50% with mineral spirits). If you know what was originally used, try to do the same.
Now you can put one or two coats of poly on those spots, but the repair will show. Usually with repairs like this, it is better to, after putting a coat or two of poly on the spots, let them dry thoroughly and then screen the entire floor, that is cut the surface with a 150 grit sanding screen on a floor buffer and then recoat the entire floor with a coat of poly. I can almost guarantee that those repair marks will not show if you do this –
