If you have cracked or otherwise damaged countertops, refinishing them is a great way to restore them to their original beauty without having to install brand new countertops. By refinishing your current countertops, you can erase the signs of damage and cracks without having to spend copious amounts of money. If your countertops are unique and must be specially made, refinishing them can save you anywhere from 30% to 50% of what it would cost to replace your countertops.
