Should I remove the floor adhesive?

[Earp_C]

Floors are up! Luckily no plywood under the rubber and zero rust! That said, there is some adhesive left after removing the rubber. “Should” I grind that off before primer? My wife and I are on the fence about it. I mean, it’s adhesvie and very hard to remove. It will need to be ground off. If it’s bonded that well, could we just clean the floor and primer over the adhesive? What would you do? Pic attached.

If you have a sealant (the glue), why grind it off to expose metal that can rust, only to cover it with primer to prevent rust?

Spray over it. The primer might not adhere well to the glue, but who cares you are covering it anyway.

I agree with Twigg...
