I bought a house in which the small front porch which is made of cement is painted. I don't have a problem with it being painted except that the area that is walked on the most is always peeling off. I have tried repainting, but the same areas peel. I would like to know if there is something I can use to seal these areas first before repainting them or if there is some type of primer I can use in order to stop the paint from peeling. Please let me know if you have a solution to my problem. Thanks.
