DIY Concrete Countertops - Finishing

Alright, where did we leave off on the concrete countertops?  Oh yeah, the SINK!  I can feel that ugh feeling coming right on back...

(Pssst...click here to read about the Part I of our new countertops.)

In our first post about the prepping and pouring, I wrote about how much of a pain it was to install the sink form.  We hoped the pain would end once the concrete was poured but when we removed the form, we had all these big voids.

The frustration was real but we had to move on and start with the process of finishing the counters before we figured out how to make the sink look better.  So, let's talk about the finishing and come back to the sink.

With the concrete completely dry (about five days after pouring), it was time to grind them down so the tops were smooth.  Even with screeding and then floating the concrete after it was poured, the counters still felt rough to the touch, slightly more smooth than something like our sidewalk but definitely not smooth enough for a kitchen sponge to glide over.
