By Glenda Taylor. A cracked or stained driveway can not only detract from curb appeal, but it can also make your entire house look dated and drab. While installing a driveway is a job for the pros, sealing one can be a simple DIY project. Left untreated, these issues can lead to larger problems such as potholes. Concrete is porous, so when ice or snow melts and then refreezes, expanding and stressing the surface, flaking and cracks can eventually appear. Here are some points to consider when selecting a product for your concrete surface.
Wide cracks in concrete are best patched and sealed with a concrete patching compound. Patching compounds typically are mixed with water and applied with a trowel. They have a texture similar to grout and can be smoothed and textured to blend with the surrounding area. However, the color of the patch will look like new concrete and will not match the old concrete. Hiding the patch completely requires painting the surface with an appropriate concrete paint.
