I have just purchased a 5 yr old home with a brick lined, poured cement front porch, approx. 8 x 6 ft. Due to contractor nonpayment issues, the cement wasn't finished level with the surrounding brick. It varies 1/16 inch to as much as 3/8's inch deep. I need a repair product that will stand up even at the thinner depth. I have considered the commercial epoxy garage coatings, but I am concerned they will be too thin to control, and don't know what problems the required thicker depths might cause. Any suggestions?
