Concrete's gone a long way in the past few years, as our Painted Concrete gallery will show. Concrete overlays for resurfacing concrete are popular on the driveway, walkway, pool patio, or basement floor. The effect can be toned down or dramatic, depending on what you've got in mind. When it comes to color, many homeowners will gravitate toward natural browns, tans, charcoals, and terra cotta reds, but you're not limited to these. In fact, you've got hundreds of shades to choose from and endless variations of textures and finishes, too.
