Polishing New Countertops

I think I'm on the final stretch polishing our counter tops.  This is the most time consuming part of the whole fabrication process.  

The polishing process started with grinding the surface of the concrete down to expose the aggregate and to remove any blotches.  Grinding the surface also exposes small air bubbles and pin holes so they need to be filled with a slury mixture.  Repeat the slurry and grinding process until counters are smooth, level, and flat.

When the counter tops were reasonably flat I began polishing them with 50 grit diamond polishing pads and worked my way up to 6000 grit pads.  

Here is one of the counter tops polished up to 3000 grit.

The photo above shows the exposed aggregate (rocks), glass, and quartz sand that I used in the concrete mix.

Just to show the difference between un-polished vs polished.  Here is the area the kitchen faucet and skink will be installed.  It's only polished to 400 grit.  The picture just after shows the same area polished up to 3000 grit.

It's slow work but we're getting there
