Finishing the White Desk

The white concrete desk was placed two weeks ago. Form were stripped after 4 or so days. Initial grouting was done at 4 days and moist cured. Initial grinding 50 and 100 grit was done at 7-days. A second thinner grout was applied with a rubber trowel. The countertop was moist cured for another 7-days until polishing. At 14 days after placing the top was polished through 1500 grit. So the full polishing scheme went 50, 100, 200, 400, 800, and 1500. I skipped 3000 grit since the sealer doesn't really stick to it. Four coats of sealer went on today. The sealer will cure for another day (it is really hot and humid in the garage right now) and will get waxed before installation.

  1. This is impressive - how thin is this and could a kitchen countertop be made that thin?

  2. The desk is 1.5" thick with a 4" drop front to cover the support. You can make a kitchen countertop that thin. The key is having good support underneath. Usually cabinets have enough support.
