Q: I enjoy your column and have a question for you. We built a home last year and have a concrete patio at the rear. It already has a crack in it (not very large) and it’s starting to stain. I would like to improve the appearance. What would be the best choice? Paint it, carpet it (I do not like the look of the turf like outdoor carpeting), lay down a stone covering over it, or something else? It is fully exposed, and we live where the winters are not very cold but the summers can get very hot. There are few trees around it so leaf stains are not really an issue.
