washing after grinding slab?

[slackdaddy1]

Just completed prepping the slab with a HD diamabrush walkbehind.
I blew the garage out with a leaf blower, but there is still a dusty slight coating.
Does it need to be washed with water? if I do wash it, wont I be making my slab moisture laden and have issues with the epoxy adhering ??

Any insight is appreciated,

Nick

If you wash it, you will have to wait a few days to dry.
Surface tension could be holding the dust.

Broom and blow or broom and vac, 3 or 4x.

You will never get it perfect as you just made it porous and open.

Some residual dust is normal and will get entrained in the coating.
