I replaced my windows and I was told that the stucco patch wouldn't match the old one which has been painted many times (sand texture). My contractor suggested a sandblasting and a skim coat. I'm worried about my budget. My stucco doesn't need major repair (other than the window patch) but the paint is peeling. I definitely need to change the apperance of the house by at least paint it. Any suggestions? Is the skim coat my only way to go?
