Hide rough concrete patio crack repairs

If you have a rough concrete driveway, patio, or walkway with minor surface cracks, one of the best ways to repair these cracks is to fill them in with concrete repair caulk (siliconized latex concrete caulk). The only problem is that once you caulk these minor surface cracks, it will be extremely obvious that a caulk repair was made because the texture and color of the caulk does not blend in with the texture and color of the concrete slab.

A trick used to help hide any minor crack repairs in your concrete floor using concrete caulk is to sprinkle ordinary play sand over the caulk immediately after you apply it to the crack - while it is still setting up - or wet. Don't be stingy with the sand, and just cover the entire area of the caulk job so that you do not risk missing any of it. If you have a colored concrete slab, patio, or walkway, or you need to try to match the sand closer to the true color of the concrete - pick up some concrete colorant from your hardware store and add it to the sand. I recommend that you mix the sand and colorant in a small plastic re-usable container when doing this.

Let the caulk and sand mixture dry, and then simply brush it all off for a clean repair. The crack lines will still be visible, but they will not stick out as badly as they would with just a caulk repair.
