Dave Ruiz and Hunter Martinez continued to grind and polish the concrete in the lower level today.

As Dave says, ‘We make a mess, clean it up, and do it all over again. And again, and again …’

This is very accurate.

The concrete is covered with 1/8 inch of concrete dust from the grinder/polisher.

Dave used a mop to wet the concrete so we could see how it was progressing.
