How do I care for and maintain my countertop once it has been sealed?

Proper care and maintenance will provide years of trouble-free service from your concrete countertop.  Concrete is like other natural stone materials and should be sealed with a product intended for its use.  No matter what sealer was used you should promptly wipe up all spills and use trivets for hot items, cutting boards for chopping and coasters or plates under bottles that may drip oils or vinegar, which minimizes the exposure to the concrete or sealer.
