Painting or staining a concrete floor

Q.    We are closing on a 2-year old house with a basement. We don’t plan to have it finished yet but would like to paint the concrete floor, the metal posts and the walls. What are the best paints to use and the best way to apply the paint?  Do we need to powerwash the floor?  The basement has French drains.

Additionally, the concrete floor has a lot of bumpy golf-ball-sized concrete nuggets. How can they be removed and still retain an even surface?

A.    To remove the bumpy nuggets, you will need to get a concrete contractor to look at them to determine if they can be removed and by what method. I do not recommend painting a concrete basement floor as it is seldom successful in the long-run. It is best to use a concrete stain after a thorough cleaning of the floor with a strong detergent. It may also be necessary to etch the concrete slightly for the stain to penetrate. The concrete contractor or an experienced painter can advise if this is necessary.
