Hello, I am preparing my exterior foundation so I can repaint it. It is poured concrete and I have a basment. I started by scraping it with a paint scraper and got off I could that way. Next I found some cracks while scraping. I then got a 2000PSI power washer to get the rest of the paint off and to clean the cracks. I then the next day washed the cracks and foundation with dulited muriatic acid. Then after it dried I filled and covered the cracks with hydraulic concrete. Now my question is I am going to be using self priming masonary paint, but should I use something before I paint like a sealer or something? I really cant wait 30 days for something to set up before I paint because I need to regrade around it as soon as I can. Thanks for any help.
