Evaluating Concrete Colors and Finishing

We need to finalize the design on our exposed concrete floors.  The design we need to establish (decide on) includes the following elements:

  1. The color, if any, of the concrete;
  2. How that color is set in the concrete (stain or integral);
  3. The finishing of the concrete (grind into the aggregate or just into the ‘cream’);
  4. The sealant (if any); and
  5. The level of polishing.

Reviewing Alternatives

Bryan spoke with Bill Clyne, who explained the differences in the various alternatives facing us, including the maintenance and other issues.  Bill recommended that we visit Safeway’s new ‘The Market‘ store in downtown San Jose.  The floor in this store is stained, sealed and polished, and has received accolades from many people.

Bryan visited the store and was fortunate to meet with Safeway’s product manager for the The Market line.  Safeway has two The Market stores, with the first store opened in southern California (Long Beach) and the second store in San Jose.

The stained and polished concrete looked great in the store.  it was a warm ‘earth tone’ and not a cold gray concrete.  Jo-Anne wants our floor to have a warm earth tone and not gray concrete.

(Bryan received permission to take photos of the stained and polished concrete floor in The Market.)
