Oil spots showing after cleaning/grind?

[busyallthetime]

Good evening. Looking for insight on an issue I came across today while staining my floor. My plan was to use H&C semi transparent grey stain to create an acid stain look and then follow it up with Legacy clear epoxy and urethane.

So here's some background info on the prep. I degreased the entire floor ans scrubbed with a brush. I pre-soaked any spots which I thought may have had oil prior. I then power washed prior to using the Diamabrush.

After power washing I hadn't noticed any water beading. Fabulous! I thought. After the Diamabrush the floor looked great. No signs of potential issues.

After I applied the H&C semi transparent stain several spots beaded up and as the pictures show its evident these spots aren't fully clean. Now I am in a dilemma.

First, are these oil spots ans how should I correct it?

Second, I am leaning to ditching the stained look and do a colored epoxy with flake to hide imperfections in the slab.

Third, anyone looking for 5 gallons of Legacy SD clear epoxy?

I know we offer an oil stop primer, they may have something similar... Also you could try Pour N Restore, but you will need to rinse thoroughly

Another good product to use would be our Oil/Grease emulsifier, then coat with our Oil Stop Primer, and coat with epoxy, flecks and topcoat.

Thanks for the responses. I forgot to mention, prior to degreasing I used Iron Out and Pour and Restore. It is possible I missed these spots with the floor being as dirty as it was.

I am going to address these spots and hopefully the outcome will be better.
