The beginning prep for epoxy

[loosegroove]

I just finished cleaning and degreasing my garage floor this past weekend in preparation for my epoxy coating (Wolverine!!!). I am planning on grinding the floor this next weekend, but I noticed this morning that the floor has a very fine white dust residue. I am assuming it’s from the cleaner because it contained Phosphoric Acid. Should I re-rinse the floor with baking soda or can I skip this process this because I am grinding the floor in a few days?

Even after cleaning / power washing I still have a couple of dime sized spots of old paint. Should I work on removing these spots before the grinder or will that take care of these spots.

Grinding will take the spots out but why not spend a few minutes cleaning spots? Might save some grinding.

If you're going to grind anyway don't bother with the residue down there now, the grinder will grind it off pronto.

Despite our efforts, we end up breathing some dust. If cleaning spots saves one minute of grinding it is worth doing.
